<h3 style="text-align: left;">
Intro</h3>
<div style="text-align: left;">
This is the first tutorial by Barium Electronics that will be dealing with using the internal EEPROM of an ATTiny using the Arduino IDE and also using the AVR EEPROM library.</div>
<div style="text-align: left;">
<br /></div>
<div style="text-align: left;">
The Arduino EEPROM library is compatible with the ATTiny range of AVR
microcontrollers as the library itself is built on the standard Atmel
AVR <code style="background-color: grey;">avr/eeprom.h</code> 'library' so it is compatible with all the AVR
microcontrollers.<br />
<br />
This was originally written back in 2016 (wow...) so some things may not match what people have floating around now :)</div>
<div style="text-align: left;">
<br />
<b>Things needed:</b><br />
<br />
<ul style="text-align: left;">
<li>ATTiny of your choice, I prefer the t85</li>
<li>ISP programmer/ArduinoISP (Pocket ISP, <a href="http://www.dx.com/p/usbasp-isp-programmer-adapter-for-at89s-series-mcu-silver-164820?Utm_rid=49285005&Utm_source=affiliate" rel="nofollow" target="_blank">USBasp</a>)</li>

<h3 style="text-align: center;">
Basics:</h3>
</div>
<div style="text-align: left;">
<ul style="text-align: left;">
<li>The EEPROM doesn't take to being written too often as
EEPROM can wear very quickly. Reading though does not cause as much damage
though, possibly none.</li>
<li>EEPROM is good for storing settings</li>
</ul>
</div>
<div style="text-align: left;">

<div style="text-align: left;">
A quick example of the way you can use EEPROM: you can run one sketch to set values in EEPROM and then use a different sketch, program to read the values you set.. That is
usually the point of EEPROM, it is a memory type that "keeps its value
while there is no power". By storing settings, you can use a ATTiny with minimal Flash space 1K, and then have another 500B of settings stored...</div>
<div style="text-align: left;">
<h4>

<h4>
<b>Note: </b></h4>
</div>
<div style="text-align: left;">
</div>
<div style="text-align: left;">
If you are programming your ATTiny using an ISP programmer (probably won't need it on a Trinket) you need to make sure the ATTiny is set to preserve EEPROM
during upload with the ISP, this is done with the fuse settings. You
need to look for a tutorial on fuse calculators for the AVRs. To set the
<code style="background: grey;">EESAVE</code></div>
</div>
</div>
you need to set the High fuse to <code style="background: grey;">0xD7</code>, you can change this in the <code style="background: grey;">boards.txt</code> file. <a href="http://eleccelerator.com/fusecalc/fusecalc.php?chip=attiny85&LOW=E2&HIGH=D7&EXTENDED=FF&LOCKBIT=FF" rel="nofollow" target="_blank">Here is a fuse calculator.</a><br />
<br />
<h4 style="text-align: left;">
<b>Start:</b></h4>
<br />
We will want to arrange our needed setup of the components. First need to setup the programming jig, this can be the ATTiny micro on a breadboard or using the Arduino as ArduinoISP with a custom or bought <a href="http://www.dx.com/p/arduino-prototype-shield-with-mini-breadboard-65273?Utm_rid=49285005&Utm_source=affiliate" rel="nofollow" target="_blank">shield </a>to program the chip.<br />
<br />
I assume in this tutorial that you already have the ATTiny Arduino extension installed on the IDE.<br />
<br />
Here is good tutorial on setting up the ATTiny libraries in the Arduino IDE:<br />
<br />
<a href="http://highlowtech.org/?p=1695" target="_blank">High-Low Tech </a><br />
<br />
It is really a lot easier with the boards manager for beginners. If you have older versions of the IDE, you can find a lot on the old way of copy and past, High-Low Tech also show how to do this.<br />
<br />
Next we will get the IDE going and set it up in the following way:<br />
<br />
<table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto; text-align: center;"><tbody>
<tr><td style="text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjOrjx6DeHmdEWt_ZSXbk-HybpZRfeyYriTADVI_227Bp3OimMUc7vxe8ewhIcKEMo2QkwT_qZA0zOJO0JgXkzaneOkJU02O8ltlf_2DvGNlCq1pDCBM-zP3ypMb6-9UWkMN6viTOf340ki/s1600/2016-11-08+10_46_20-.png" imageanchor="1" style="margin-left: auto; margin-right: auto;"><img border="0" height="366" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjOrjx6DeHmdEWt_ZSXbk-HybpZRfeyYriTADVI_227Bp3OimMUc7vxe8ewhIcKEMo2QkwT_qZA0zOJO0JgXkzaneOkJU02O8ltlf_2DvGNlCq1pDCBM-zP3ypMb6-9UWkMN6viTOf340ki/s400/2016-11-08+10_46_20-.png" title="Click to see a larger image" width="400" /></a></td></tr>
<tr><td class="tr-caption" style="text-align: center;">IDE preferred setup</td></tr>
</tbody></table>
Now that the IDE is setup and the bootloader is burnt we move onto the code.<br />
<br />
<h3 style="text-align: center;">
<b>Code:</b></h3>
<div style="text-align: left;">
The first bit of code we are going to discuss is the way in which you will need to read/write the EEPROM on the MCU.<br />
<br />
For Reading you will do the following with the Arduino library:<br />
<br />
<code style="background: grey;">EEPROM.read(__addr); //where __addr is an int of the EEPROM addr number</code></div>
<div style="text-align: left;">
<br />
the Arduino library simplifies the use of the EEPROM by making it easy to use, if it were to be done with the AVR library, it would look something like:<br />
<br />
<pre><code class="prettyprint linenums:1"> eeprom_read_byte((uint8_t*)__addr);
//you need to make __addr a pointer to the type you are using </code></pre>
</div>
<br />
avr-libc definition:<br />
<br />
<pre><code class="prettyprint linenums:1">uint8_t eeprom_read_byte ( const uint8_t * __p )</code></pre>
<br />
For further explanation of more in depth discriptions of the AVR libraries, check <a href="http://www.nongnu.org/avr-libc/user-manual/group__avr__eeprom.html" rel="nofollow" target="_blank">avr-libc</a>.<br />
<br />
When you want to store data into the EEPROM, bear this in mind, each cell is 8 Bits / 1 Byte. When you write to the EEPROM using the Arduino library, do the following:<br />
<br />
<pre><code class="prettyprint">EEPROM.write(__addr, __val); // __addr = 0-1023 for UNO, __val 0-255</code></pre>
<br />
I prefer to use the <code style="background: grey;">eeprom_update_byte(uint8_t* __p, uint8_t __val);</code> this is because it updates the bits that need to be change only, and it thus reduces the wear on the EEPROM, this coupled with wear leveling, it should make the EEPROM last a while.
<br />
<br />
<h4 style="text-align: left;">
Getting to some code:</h4>
<div style="text-align: left;">
Below is some code that writes a value to the EEPROM of a set value, and then makes use of that value later on in the code to blink an LED on one of the pins<br />
<br /></div>
<pre><code class="prettyprint linenums:1">
/* EEPROM demo code for the ATTiny. This code sets a variable in the
* EEPROM that is then used in the main loop.
* By Ba_E (RSM)
* 2016-09-10
*/
#include "EEPROM.h"
byte CLK = 0; //This is a global variable with an initial value
void setup() {
// put your setup code here, to run once:
if(!EEPROM.read(0)) EEPROM.write(0, 1); //set the pin to D1</code></pre>
<pre><code class="prettyprint linenums:1"> </code></pre>
<pre><code class="prettyprint linenums:1"> delay(5);
//read from EEPROM address 0
//this sets the value of the global variable CLK
CLK = EEPROM.read(0); //place this inside a function
//just to give an example...
byte PIN = CLK; //PIN variable is a local variable
pinMode(PIN ,OUTPUT); //using that local variable
}
void loop() {
if (!CLK) {
for (int a = 0; a < 3; a++) {
digitalWrite(CLK, HIGH); //this uses the global variable
delay(1000);
digitalWrite(CLK, LOW);
delay(1000);
}
}
else {
for (int a = 0; a < 100; a++) {
digitalWrite(0, HIGH); //this has a predefined pin no.
delay(500);
digitalWrite(0, LOW); //this has a predefined pin no.
delay(500);
}
}
}

</span>
<span style="font-family: "arial" , "helvetica" , sans-serif;">The program is quite simple, it sets the pin that you want to use for writing to in the EEPROM and then uses it to set the digital pin, this is just an example of showing you how you can use the EEPROM. </span></div>

</div>
<div style="font-family: -webkit-standard;">
<span style="font-family: "arial" , "helvetica" , sans-serif;">An example of using it more extensively for a settings thing is to have a set of values set in hex or a single arduino program for the fun of it to interpret the serial data and set the eeprom, then extract that eprom data as a setting file you can flash onto all of your devices or program into an I2C eeprom :)</span></div>

So a while ago I answered a question on <a href="http://arduino.stackexchange.com/q/28876/2944" target="_blank">Arduino.SE</a> with regards to a person wanting to shield there Arduino from EMI( Electromagnetic Interference) that was coming from some AC they were feeding into a shield on the Arduino, and thus they asked if it would be plausible to use a shield in between the Arduino and the other device to stop interference. Thus I brought out some points to help that person.<br />
<br />
Some things I answered in it:<br />
<br />
<ul style="text-align: left;">
<li>Using DC Ground</li>
<li>Using AC Earth/Ground</li>
<li>Isolating circuitry </li>
<li>Extra, PCB layout </li>
</ul>
<ul style="text-align: left;">
</ul>
<br />

<h3 style="text-align: left;">
Methods</h3>
<h3>
DC Ground</h3>
If you connect the DC ground from the main board you should use a <code>ferrite bead</code>(FB)
between the two grounds, this will ensure that you don't get noise
getting back into the ground of the main board after you have tried to
shield it. You should try to match the ferrite bead to the noise
frequency you experiencing (use a scope if you have one).<br />
Using the DC ground as a shield is often done, if you look at the EMI
cages on cellular phones, WiFi modules, and other noise generating
devices/susceptible-to-noise devices, they are connected to ground. It
gives the noise somewhere to go, instead of your signal lines. <b>Thus
using the DC ground is defiantly an option</b><br />
<br />
i.e.:<br />
<pre><code style="background-color: grey;">Main ground]--------[__FB__]-------[shield </code></pre>
<h3>
</h3>
<h3>
AC Ground</h3>
You could use the AC earth line on the top part of the shielding
board. The coupling part might be a bit over kill, leave space for it to
test to see if it helps when you make the board. Also AC earth can be
used for shielding but is used for the safety aspect of earth leakage.<br />
Don't do a direct <i>DC ground</i> to <i>AC ground</i> unless you
know what you are doing as this will create a ground loop, this will
change the way stuff behaves and will make your circuit no longer a
floating device, or in another way it won't be and isolated circuit, but now referenced to mains ground/earth.<br />
<h3>
Other stuff</h3>
I would also make sure how you drive the relay is isolated from the control circuitry, although from what the OP had described:<br />
<blockquote>
<blockquote class="tr_bq" style="background-color: grey;">
if I move the shield further away I also don't see the issues.</blockquote>
</blockquote>
If you share power rails between the relay board and the main board,
try filtering the power coming from the Arduino shield or the power that is being supplied <b>and</b> shared between the two. Also the control lines
can be isolated between the controller and the relay with
opto-couplers, this might stop noise coming back into the circuit from
the relay part.<br />
<br />
<div style="text-align: left;">
<h3 style="text-align: left;">
PCB designs</h3>
<div style="text-align: left;">
I have made a initial design idea with Eagle, and put it into a GitHub repo, thus please change, improve or add to the design. I plan on adding more designs to make it more multi-design so that it can meet different needs.</div>

I was in need of a sound sensor board because I wanted to test some code that someone was experiencing issues with, so I scrounged around for some scrap parts and decided to make a free form circuit of the common sound sensor circuit, I used this as a base:</div>
<div class="separator" style="clear: both; text-align: center;">
<a href="https://lowvoltage.files.wordpress.com/2011/05/lm358_mic_amp1.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="137" src="https://lowvoltage.files.wordpress.com/2011/05/lm358_mic_amp1.png" width="320" /></a></div>
I made some modifications for the look of it, such as the ceramic caps and not the electrolytic ones.<br />
<br />
The modification I made to the circuit was the addition of a comparator using the free half of the LM358. That is what the green trim pot is for at the top of the circuit.<br />
<br />
I used enamel coated wire from a stripped transformer. The other parts were from various PCBs I have collected... <a href="https://lowvoltage.files.wordpress.com/2011/05/lm358_mic_amp1.png" rel="" target="_blank">Hackaday calls it Fracking</a>. <br />

That seems to be about all the photos I took. But the idea is simple in that you take the wire and bend it around a cylindrical shape of your choice and arrange the curves to the way in which it best fits. </div>

I have been busy with work and working on and off with the weather station. I have been working a bit on the FARS lately and have gone with plant pot basses with a 120mm diameter and made a 50mm hole in the centre for sensors and a 50mm PC fan I found/had lying around. I used 160mm 5mm thread bar by three, I used straws to hold each base at 10mm apart; each base is 20mm, 10mm is half way where the centre rim is, so it gives a nice overlap.<br />

I have also painted the whole thing white hamerite. It looks the part, and hopefully after I have a solar panel for it I can test the setup.<br />
<br />
Next I have been fiddling with the sensor circuit for the wind vane, I had a bit of an issue where I ordered IR LEDs and phototransistors $3mm$ OD, the opto sensors where clear, but I ended up with clear IR LEDs, so I had to re-order. To the circuit... I used an LM324 quad op-amp, 100k pull-down resistors on the phototransistors emitters, and $1/2V$ to the non-inverting input.<br />
<br />
An idea I had for the circuit to basically be a three wire system was to have the amps, a CD4017 and AND gates, tiny4/85 and then pulse the CD4017 and it would 'scroll' through the AND gates and relay that signal to the tiny if it was true from the op-amps. Sort of like parallel in serial out.<br />

<br />
The diodes protect the AND gate outputs. The schematic is not complete and should not be used. The first part is what I started working on so far, LEDs are for output.<br />

Next I have done some turning on the lathe with some brass, stuff is so fun to turn I 'sort of' under cut the part by $0.2mm$. It is a shaft holder for the anemometer, it allows the movement to be translated to the inside of the body of the thing so that I can use a reed switch and magnet as the sensor, it was also meant to provide a tighter fit to the bearing. I then attached it the same way as the original one.<br />

So I have been working on the anemometer on and off for the last month as I have also been working on another project. I have also been working on the final design of the weather vane setup and slicing my thumb :) This will be part one of this part of the weather station, discussing mainly the anemometer.<br />
<br />

The basic build</h3>
<h2 style="text-align: center;">
<a name='more'></a></h2>
I started off with some cheap ping-pong balls, seems I was going to hack them up.<br />
They were about R13($1) for a pack of 6, this was nice. I started by cutting two in half, this gave me the three cups and the cover piece for the shaft to give a nice clean look. The edges must then be trimmed as depending on your method of cutting them it might leave an unclean finish.<br />
<br />
<div class="separator" style="clear: both; text-align: center;">

<br />
I then cut the shafts from some brazing rod and got some tin left over from the rain gauge.<br />
The dimensions of the anemometer determined the length of the shafts. I chose to use the 7.5" diameter this meant that the total diameter of the anemometer had to be $190.5mm$. So the diameter of the balls is $37mm$ (3mm less than stand.) therefore we get the length of the shafts by: $$\begin{eqnarray}l &=& \left(\frac {190.5 - (37*2)}2\right)\\<br />
&=& 57mm<br />
\end{eqnarray} $$<br />

</tbody></table>
The next thing would be to attach the shafts to the ping-pong balls. This was achieved by cutting the tin into 20x5mm strips, drilling 1.5mm holes at the ends and soldering the shaft to the centre of the tin strip. Before soldering the tin and rod, ensure to ruff the surface.Once the pieces are soldered together you will then curve the surface of the tin and cant it back a bit to fit the profile of the sphere. Repeat this two more times.<br />

Next I attached these to the ball halves, this was done with a nice idea, what I did was I placed the strips against the ball and marked holes. Next I piloted the holes with a large pin into the plastic, then used a heated metal rod to open up the holes to 1.5mm. I then found myself some 1.5mm nylon line for fishing.This was inserted into the holes and the metal strips.Once it is in the holes, take a blow torch and heat up the end of a pair of pliers, then when it is hot(warm enough to melt plastic), squeeze the pliers over the nylon line, so that it makes a flat rivet effect.<br />

Next I turned up some things to hold the whole thing together. I went through quite a few ways in which to do this, working through ideas as I wanted to try other ways to do it than using a ball bearing setup. Although I ended up using the ball bearing in the end as it provided the best stability at high speed.<br />
<br />
<h3 style="text-align: left;">
<b><span style="font-weight: normal;">First one:</span></b></h3>
I made up a steel shaft and a nylon body that clipped together, the nylon would theoretically spin because of the 'loose' fit, yet stay on because of the lip. This idea worked, it clipped on, didn't come of without sufficient force, but it would probably spin if you put it in the way of a cyclone. The nylon has dimensions of $20mm * 15mm$, the nylon also has three holes just under the sphere shape, at $120°$.<br />

Third:</h3>
Next I thought of using a DC motor, that was very responsive and would have been nice to use, unfortunately the thing was a bit of a pain to attach to the final design. So I scrapped that idea as it was also going to be fun to extend the shaft of that I had.<br />
<br />
<h3 style="text-align: left;">
Fourth:</h3>
<div style="text-align: left;">
I used steel rod again, and some solid brass rod. I then drilled out the brass rod as close to 3.2mm because of the drill bit being .01 too small. I then sanded the steel shaft with 1000 grit wet/dry cabinet paper, and then I also sanded the now brass tube with graduating grits of cabinet paper, starting at about 400 and going to 2000 odd. This was done with a dremel tool. You take a strip of sand paper, get a split pin, slip the paper in the pin and insert that into a dremel tool. Then you take this and put it into the tube when running and ream it out. This is done until the rod spun freely inside. <b>Make sure you clean out the tube before insertion</b> or it will grind out the inside with little burs when it is running. I ended up using this for most of the tests, as it seemed to work pretty well. But in the end I dropped it as it would get a sort of speed wobble.</div>

Before I changed over to the bearing style, I built the rest of the anemometer body. I first drew up the design and did an ISO. After it was draw I transferred the main points to the tin, so that I could use a compass to draw the development. I then used the compass with a sort of chisel thing I had lying around to score the metal. Then I cutout the development. This was then bent and rolled over a cylinder to get the curve and final shape of the base. I cutout and ground the top circle and the bottom one(which became of no use later). These were all soldered together and the brass shaft was inserted and soldered into the hole.<br />

The above setup was used to test the anemometer in some wind and it actually worked! Quite cool, but with the bearing setup the anemometer is able to pick up breezes better<br />
<br />
I then sliced my thumb when cutting another piece of tin, when from the tension it was under it sprung back and the corner sliced the top of my thumb, I kinda saw some bone or other tissue. And it bleed a lot... surprisingly?<br />

Finally I moved to the bearing setup. This entailed redoing a nylon centre block, and a base for the bearing to connect to. I under cut the base so I needed to add some PTFE tape to get it to stay, not a real problem. The steel base was then attached to the tin plate. The old brass tube was reused on the wind vane later on.<br />

Adding the small strip to the anemometer base, this is to allow it to attach to the $50mm$ PVC pipe.<br />

The anemometer and wind vane were then put on the roof for a few days, less the wind vane as it was not really stable at that point, this was just to test the design and its response. A <i style="font-weight: bold;">crude </i>test setup. <br />

In conclusion it was an interesting build, learnt a lot, and went through a few designs. The whole design of the weather vane is drawn by hand and at some point I will scan and upload it. The wind vane construction will be in a second post.</div>

For code and some designs(to come at this point) I have setup a <a href="https://github.com/ReeceM/AWS" target="_blank">Github repo</a>, it has some of the code that I used to test the anemometer and the theory code for the wind vane.</div>

A general update of the weather station. The anemometer is coming along nicely, except for changes in final design and construction which I keep making. I am working on a build post for that, which should be up soon.<br />
<br />
I received components I ordered the other day so that I can start getting some basic data.<br />
<br />
I have a BMP180, DHT22, and 2 RFM12Bs, pictured below for fun:<br />

I have so far tested the <a href="https://github.com/adafruit/DHT-sensor-library" target="_blank">DHT22 with the library from Adafruit</a>, it worked well.<br />
I have yet to have some time to test the other stuff and also to find a suitable library for the RFM12 module which doesn't have a heap load of stuff added in. I also have to make level shifters for the two transceivers. <br />
<br />
I got these through a local distributor for <a href="http://www.sparkfun.com/">SparkFun Electronics</a> who had reasonable prices, which is better than paying the import costs and overseas postage.</div>

So I have been toying with some names for my business & blog as the name is representative of my blog and of my actual business I have. I have thus officially re-named my blog and business today as: <br />
<br />
<ul style="text-align: left;">
<li> The company is not too big that it will cause a huge mess with customers and my blog.</li>
<li> Search the word Ziggy, Ziggy Electronics or ZE this gave some weird results which are not fit for a business when customers search.</li>
<li> Most people scoff at the name? Or at least a quizzical look, possibly the odd word.</li>
</ul>
<br />
So I have changed the name to something unique and more related to the electronics side:<br />
<br />
<h2 style="text-align: center;">
<span style="font-size: x-large;"><span style="font-family: "Helvetica Neue",Arial,Helvetica,sans-serif;"><i><b>Barium Electronics </b></i></span></span></h2>
<div style="text-align: left;">
<br /></div>
This is a name which is not used as a company name by anyone I can find. This should make the blog easily found by search engines as not much turns up in electronics projects, this should increase the traffic. </div>

For
the first build post I will be starting with the rain gauge. This is
based off the tipping bucket rain gauge method. These are pretty easy to
make and get running.<br />

<div style="text-align: left;">
The above picture is
from the 1-wire design which is a common picture, I used this to get the
basic design principle. Mine is constructed from tin from an old juice
concentrate can. The design was hand drawn to get the sizing that I
wanted and I could see the life size thing. </div>
<div style="text-align: left;">
<br /></div>
<div style="text-align: left;">
The enclosure is made with ABS plastic sheet that I had lying around, but anything that can be cut and glued should work. </div>
<div style="text-align: left;">
<br /></div>
<div style="text-align: left;">
The
design of the catchment area of the enclosure is very important as that
plays a role in what the amount of rain is caught and the amount per
tip. What is needed is a catchment area of $100cm ^ 2$ this equates to
$10mm$ of rain being caught by the system, but because this is 100 times
smaller, the $10mm = 1mm$ per $1m ^ 2$. Then the trick is to calibrate
the sensor to tip at a specific point, this can be between .01 to 1mm of
rain, but this is to the needs of the area. Mine by default ended up by
being $0.25 mm$ per tip, this is nice as I can pick up the sometimes
common drizzles where I live.<br />
<br />
I was originally going to
use the reed switch and magnet method as this uses less power to run
the system, but the little glass tubes broke every time I worked with
them, I went with a reflective IR sensor after that and ensured its
current is 10$mA$ at 3.3 V.<br />

Start by cutting off the
base that is left on the bottom, then cut up the join mark of the tin,
this gives one a straight line to follow when cutting. Next you will
trim the top and bottom of the tin so that you can open it flat (the
curly bit). Next is to mark out the dimensions on the flat piece.<br />

Then
what is needed is to drill the hole for the axle $3.2mm$, this is $5mm$
from the base, You will drill the side that is attached. Then you will
place the other side behind that and aligning the two mark the hole on
the unconnected piece. Then drill and attach it using the above method.

The Enclosure</h3>
<div style="text-align: left;">
The enclosure for
the bucket was made using ABS plastic sheet. The internal dimension of
the rectangle is $120mm * 80mm$, this gives a catchment area of the
$100cm ^ 2$. The height of the enclosure is 100mm, and the funnel is
placed 20mm down from the total height, this gives some free board if
there is a lot of rain.</div>

From the first pic you can see the threshold adjustment screw that was placed about 33mm away from centre.<br />
<h3 style="text-align: center;">
Sensor</h3>
Next is to attach the sensor components. This is done
using a IR LED at $940nm$ and a matched Phototransistor. The reflector
is attached to the bucket at centre, this is just a strip of the tin.<br />
<div class="separator" style="clear: both; text-align: center;">

<br />
<br />
The
signal is $Active_{HIGH}$ which keeps the current consumption down.
Also I used a 330$\Omega$ resistor on the LED at 3.3$V$ as there is no
need for a bright IR signal as it is <10mm away from the reflector.
The signal is then connected to a Digital pin. I used a comparator to
'Level Shift' the 3.3V signal for the Arduino UNO to understand, this is
as its max voltage varies between 1-1.5$V$.<br />

$R5$
and $R4$ are chosen to give a voltage just below the active voltage,
about 0.4V, with a final part being really weird that I only used a
pull-up resistor of 1$k\Omega$ to get the circuit to work.<br />

Catchment area</h3>
<div style="text-align: left;">
The catchment part
of the tipping bucket rain gauge was not built off a drawing/design, so it was more of a
process of elimination of fitment and seeing where how it would fit. I
used one tin to make it, the centre square piece is $30 x 15mm$ this is
from centre. The hole was drilled to a 3.2mm diameter and punched again
so as to create a lip downwards for water flow. From the corners of the
smaller rectangle lines were drawn outwards and then cut and soldered. </div>

Test Run</h3>
<div style="text-align: left;">
I tested the rain gauge
for a day or two when it was raining and it was actually very accurate. I
left it for a while after it rained to look at it again and saw some
flash rust on some areas which must have been exposed, this was before
painting, this was odd as the tin had some sealant over it. It also come
up on the shaft which was a bummer. This was solved by partial sanding and spraying with silicone spray. Also after the tipping bucket was painted, it was also sprayed with the silicone and the catchment area. This was done to help the water flow better because it was pooling in some areas and causing it to fail.</div>

<div style="text-align: left;">
<br />
The function $tip()$ is something I wrote for another program which became useful in this code, it just checks to see if the variable that you put in. When it is only working with logical 1 and 0, and you place it in an if() statement looking for a logic 1, it only ever triggers on a 0-1 transition. One thing though with this was that I had to set "<span style="color: #cc6600; line-height: 16px;">int</span><span style="line-height: 16px;"> previous = 1; </span><span style="color: #7e7e7e; line-height: 16px;">//no false reading on boot</span><span style="font-family: inherit; line-height: 16px;">" because as the comment says, I was getting false readings from the code on the first time the thing ran</span><br />
<br />
The code originally used interrupts, but with one tip it triggered about 100+ counts and gave some seriously weird results. So I just made it loop in the code to check for the change, and because the code never opens serial and also looks for the log button, its pretty much immediate. I do believe though that I will probably add the interrupt functionality for the rain gauge and the anemometer.<br />
<br />
When the log button is pressed it stores the $count$ variable into eeprom and flashes th onboard LED, $state$ also makes it so you can only do this once until you open serial and read the value. This was done because when it was setup away from the PC and then powered on and off, data was lost or when it was connected to the PC and the terminal was opened, data was lost because of restarting :(<br />
<br />
<h3 style="text-align: center;">
Results</h3>
<div>
The results of the rain gauge were good. I compared the values with a normal rain gauge. The system was tested over about three days, the tipping bucket was within about $0.5mm$ at most from the reading on the normal rain gauge. This also picked up about a $0.75mm$ drizzle. The readings are very accurate and I believe I have made a decent design of this and it looks nice. </div>
<div>
<br /></div>
<div>
The op-amp circuit and the tipping bucket combined draw a total of $9.1mA$ at $3.3V$, this I think is reasonable and should make it excellent for battery operation.</div>

<div class="separator" style="clear: both; text-align: center;">
</div>
I have decided to dive into the adventure of building a functional automatic weather station(<a href="http://en.wikipedia.org/wiki/Automatic_weather_station" target="_blank">AWS</a>), there are a lot of these projects on the web and are easily copied and pasted, but I feel this is not worth doing because you don't really learn anything from this.<br />
<br />
What I plan to do is write a series of blog posts detailing the build process of the weather station, describing my build of all parts separately and then finally bringing it together in a final post and a permanent web app with forecasting and logging of weather for where I live.<br />
<br />
I will be designing the station to be completely self-powered, this will be done by using a wind turbine and a solar panel, these will charge I am thinking of 3V coin cells, each one possibly powering a set of sensors and the micro.<br />
<br />
The weather station will send the collected data to the base station located in the house and will manage storage and the method of either hosting or pushing the data to a storage site.<br />
<br />
The station will contain the following functionality:<br />
<br />
<ul style="text-align: left;">
<li style="text-align: left;">Temperature</li>
<li style="text-align: left;">Humidity</li>
<li style="text-align: left;">Wind Speed</li>
<li style="text-align: left;">Wind Direction</li>
<li style="text-align: left;">Barometric Pressure</li>
<li style="text-align: left;">Light Intensity</li>
<li style="text-align: left;">Visibility( or a sort of mist sensor)</li>
<li style="text-align: left;">Rain Gauge</li>
<li style="text-align: left;">Wireless Transceiver</li>
</ul>
<div>
I'll add more as I find other interesting stuff to monitor.</div>
<div>
<br /></div>
<div>
The base will have:</div>
<div>
<ul style="text-align: left;">
<li>Display for sensed values</li>
<li>Wireless Transceiver</li>
<li>Storage</li>
<li>GSM to upload to server if needed</li>
<li>A display for the current or predicted weather</li>
<li>RTC</li>
</ul>
<div>
The Transceivers will be either 434MHz or the 2.4GHz range, although its only < 9m of distance between sensor and base(line of sight).</div>
</div>
<div>
<br /></div>
<div>
I also believe I might have a use for this site http://www.weewx.com/, it produces graphs and pages for weather station data and is <b>LINUX compatible! </b>Therefore the next logical thought is to run it on a Raspberry Pi which the system supports which will be awesome. </div>

Mine needs a bit of work in the code but I generally prefer to do something from scratch by myself after seeing an idea. Mine is also a bit larger as it is veroboard.</span><br />

Design</h4>
<div>
<br /></div>
<span style="font-family: Arial, Helvetica, sans-serif;">The parts are all hacked off of other dead RC toys and boards, ATTiny85 is the only thing I paid for, makes me happy. The system uses a small LiPo striped from crashed mini RC helicopter, nice and light. The board layout was worked out in building, working around the socket as it was meant to be a 8 pin PIC proto-board. </span><br />
<span style="font-family: Arial, Helvetica, sans-serif;"><br /></span>
<span style="font-family: Arial, Helvetica, sans-serif;">The wheels were made from ABS sheet, using a circle template at 23mm. Using the four centre marks on the diameter I drew between opposite ones to get the point to make a hole for the shaft, I used a dividers point and checked every now and then to see the fit, just push on with reasonable pressure. </span><br />
<span style="font-family: Arial, Helvetica, sans-serif;">I used marine silicon to create a tread. This is done by running two strips along ABS sheet at the distance of the wheels, and roll back and forth.</span><br />
<span style="font-family: Arial, Helvetica, sans-serif;"><br /></span>
<span style="font-family: Arial, Helvetica, sans-serif;">The battery is charged by a full spec LiPo balance charger through the headers, the switch is moved towards the header toput in charge mode.</span><br />

<span style="font-family: Arial, Helvetica, sans-serif;">I have finally found a very good plugin for generating 3D PCBs.

<div>
My new plane is a Fly Cat X-75 delta wing EPO plane. The kit was an ARTF style with ESC and brushless, but I had a lot of fun with the power-train. First the ESC was not working, get replacement, ESC makes smoke signals on bench testing (not even running), I then got a higher spec'ed one from my supplier and finally on the maiden the motor rattles around not cool. </div>
<div>
<br /></div>
<div>
There is a brief video at the end and in those few seconds of panic I found my plane has a good glide angle and very responsive even when there is no thrust.</div>
