Bluetooth 4 on IOS is working well. Here are a few pictures saved from the latest version. It is now using OpenGL ES 2 for rendering so it performs much better. It also makes it easier to smooth the temperature readings overlay to look better. Still working on auto-ranging the color ranges and I need to add a few more color ranges to pick from.</div>

Anyway, on to the Open Source Hardware thing. <a href="http://blog.makezine.com/author/phillip/" target="_blank">Phil Torrone's</a> article <a href="http://blog.makezine.com/2012/02/14/soapbox-the-unspoken-rules-of-open-source-hardware/?parent=Opensourcehardware" target="_blank">The Unspoken Rules of Open Source Hardware</a> has some very good information on what seems to be the current state of OSHW, or possibly how it should be anyway. There are also some good points in a response by <a href="http://dangerousprototypes.com/author/ian/" target="_blank">Ian Lesnet</a> in <a href="http://dangerousprototypes.com/2012/02/15/a-culture-of-ethics-in-open-source-hardware/" target="_blank">A Culture of Ethics In Open Source Hardware</a>. So I am trying to be a good community member and share info on my projects while still trying to make a living at OSHW. We'll see how it goes!<br />
<br />
What I have for you today is the Arduino code I used in the video. It is available at <a href="http://github.com/RHWorkshop/TIPIC-Arduino" target="_blank">github.com/RHWorkshop/TIPIC-Arduino</a> It still needs a lot of work but I wanted to get a prototype working for the <a href="http://www.instructables.com/contest/independence/?show=ENTRIES&sort=HITS_TOTAL" target="_blank">Instructables contest</a>. Also, a quick <a href="http://fritzing.org/" target="_blank">Fritzing</a> sketch of the bread board for this is <a href="http://github.com/RHWorkshop/TIPIC-Hardware" target="_blank">here</a>. I will have the iPhone code posted very soon I just have to clean up a lot of confusing and or unused stuff. It will be available at <a href="http://github.com/RHWorkshop" target="_blank">github.com/RHWorkshop</a> in a day or two.<br />
<br />

Thermal Imaging Phone Camera<br />
I have a 100 year old house that can be drafty and hard to heat in the winter. I have been wanting a thermal imaging camera to help find leaks ever since we bought this house. So I finally just made my own.The temperature readings are overlaid onto the phone's camera display. The display is adjustable for different temperature ranges and can show the numeric reading for every zone or just 1.<br />
<br />
No, it is not as nice as the $2000 - $10,000 cameras but it is good enough for most things you need a thermal imaging camera for and it is also rather fun to play with too.<br />
<br />
I would like to make and sell these so others like me can save money and energy. I should be able to manufacture and sell them for around $150. The software for iPhones is ready, the Android software will be available soon. This is also going to be an Open Source Hardware project so if you want to make your own that is fine too.<br />

I need a cheap universal joint for a project I am working on so I have been playing with a few options. This is the one that seems the best so far. It is using a plastic ball from a wall track toy which is pretty far from a perfect sphere but it seems to work very well anyway. For the project I will use a cheap 1/2" steel bearing and laser cut the pieces from <a href="http://en.wikipedia.org/wiki/Polyoxymethylene" target="_blank">Delrin</a> which has low friction. I will probably use nylock nuts on the screws to be able to adjust how stiff the movement is.<br />

</div><div style="text-align: left;"><a href="http://en.wikipedia.org/wiki/Stereolithography">Stereolithography</a> <span class="Apple-style-span" style="text-align: center;">(SL or SLA from Stereolithography Apparatus) is an additive manufacturing process using a vat of liquid UV-curable photopolymer "resin" and a UV laser to build parts one layer at a time. On each layer, the laser beam traces a cross-section pattern of the part onto the surface of the liquid resin. Exposure to the UV laser light cures, solidifies the pattern traced on the resin and adheres it to the layer below.</span></div><div style="text-align: left;"><br />

<div style="text-align: left;"><span class="Apple-style-span" style="text-align: -webkit-auto;">I have wanted a 3D Printer for a while now and there are some very reasonably priced kits available like the <a href="http://www.makerbot.com/">Makerbot</a>, <a href="http://www.ultimaker.com/">Ultimaker</a> and the <a href="http://reprap.org/">RepRap</a> project. I could have just bought a kit and started printing things but at the time I had not seen great resolution or print quality from those. I started looking around at the other 3D printing technologies and found SLA made some amazing quality prints, so I decided to try making my own. Since I started this a while back those projects have come a long way and they can make some <a href="http://davedurant.wordpress.com/2011/10/12/ultimaker-faq-but-what-about-the-quality-of-prints/">beautiful prints</a> now. There are also people working on a UV resin and <a href="http://3dlprint.com/">DLP projector 3D printer</a> which is showing promise. </span></div><br />

Alright, I've been meaning to post an update for a while now, I was just hoping to have finished the rebuild by now... Anyway, I have been working on a UV/Visible cure resin 3D printer using a 405nm laser. I started off thinking if I could mix a Delta Robot and a resin printer in one it would be ultra double awesome. While it was pretty darn cool and fun to build, it just didn't work great.<br />
<br />
I first started with a dynamixel servo based delta robot design thinking they should have a decent resolution.<br />
<br />
<iframe allowfullscreen="" frameborder="0" height="345" src="http://www.youtube.com/embed/zXI9c-xbyNM?rel=0&hd=1" width="560"></iframe><br />
<br />
Then after I built it, I found that was not the case, at least for 3D printing purposes. Also the controller started resetting every couple of moves so I probably fried it somehow.<br />
<br />
At that point I did some more research and found some people working on a <a href="http://www.reprap.org/wiki/Delta">delta robot for use as a reprap printer</a>. Following their design I used steppers and gears. The gear ratio was chosen mainly for what would be easy to cut on the taig mill. All worked out on paper it looked like it would have a decent printing resolution. My brother drew it up and we got to work cutting it.<br />
<br />
<br />
<div class="separator" style="clear: both; text-align: center;"><a href="http://3.bp.blogspot.com/-66DW-lOAcO0/TlR1vkYcnoI/AAAAAAAAEJc/WYFqsLGuS2E/s1600/Delta+Robot+xray.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="153" src="http://3.bp.blogspot.com/-66DW-lOAcO0/TlR1vkYcnoI/AAAAAAAAEJc/WYFqsLGuS2E/s200/Delta+Robot+xray.jpg" width="200" /></a><a href="http://1.bp.blogspot.com/-SpYU5UJvKPw/TlR1p9J0kMI/AAAAAAAAEJU/5dv7SRjDizk/s1600/DeltaParts.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="148" src="http://1.bp.blogspot.com/-SpYU5UJvKPw/TlR1p9J0kMI/AAAAAAAAEJU/5dv7SRjDizk/s200/DeltaParts.jpg" width="200" /></a></div><br />
We made the Z axis pretty much out of scraps and it didn't work the best. (linear servo... what was I thinking?) It was good enough to test the theory though.<br />
<br />
<div class="separator" style="clear: both; text-align: center;"></div><div class="separator" style="clear: both; text-align: center;"><a href="http://1.bp.blogspot.com/-Aq8NtOG-NaQ/TlR-lZfBh1I/AAAAAAAAEJg/XS4dcCecO-Y/s1600/IMG_1140.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="180" src="http://1.bp.blogspot.com/-Aq8NtOG-NaQ/TlR-lZfBh1I/AAAAAAAAEJg/XS4dcCecO-Y/s320/IMG_1140.jpg" width="320" /></a></div><br />
After assembly and mangling the reprap firmware into a usable shape for a delta robot we were ready to go.<br />
<br />
<iframe allowfullscreen="" frameborder="0" height="345" src="http://www.youtube.com/embed/-Thz-v1NF6s?rel=0&hd=1" width="560"></iframe><br />
<br />
Yeah, it printed an awesome lump! It was supposed to be a small hexagon.<br />
<br />
<div class="separator" style="clear: both; text-align: center;"><a href="http://1.bp.blogspot.com/-mrJYrKIzA3A/TlR_PQTZMbI/AAAAAAAAEJk/a3f5WKlP7fE/s1600/IMG_1142.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="180" src="http://1.bp.blogspot.com/-mrJYrKIzA3A/TlR_PQTZMbI/AAAAAAAAEJk/a3f5WKlP7fE/s320/IMG_1142.jpg" width="320" /></a></div><br />
<br />
<div class="separator" style="clear: both; text-align: center;"><a href="http://4.bp.blogspot.com/-ppANuPcHhD8/TlR_QhWT7WI/AAAAAAAAEJo/j5_RRlBI2X0/s1600/IMG_1142-1.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="180" src="http://4.bp.blogspot.com/-ppANuPcHhD8/TlR_QhWT7WI/AAAAAAAAEJo/j5_RRlBI2X0/s320/IMG_1142-1.jpg" width="320" /></a></div><br />
So, what went wrong? First off I think that shooting a laser at a shiny aluminum plate is going to make the laser reflect all over... Yup, also I think dye needs to be added to the resin to help with the reflections and diffraction. The delta robot worked alright but I just didn't feel it would make the best quality prints. There was a little too much backlash and the inverse kinematics is not my thing.<br />
<br />
So now we have redesigned, again, but this time back to the tried and true (but boring) Cartesian robot. Here is the X and Y axis, still working on the Z axis redesign but hopefully soon we will have <strike>more acrylic lumps</strike> cool 3D stuff printed.<br />

Here is a video of cutting a brass sign for a Christmas present. It was the first time I cut brass on the Taig mill so I went pretty slow. The video has most of the cutting sped up 4x so it is a little more interesting. Merry Christmas Brian and Amy!<br />

To hold the sign in place during the through cut I used the Tabs feature in VCarve Pro. Then I used a hacksaw blade to cut the tabs and a file to remove the rest of the tab.<br />

<br />
This year the boys wanted to be Mario and Luigi. Kind of boring right? Well my wife didn't think they were ready for throwing real fireballs so we did sound effects instead. I wanted them to make the Mario jump sound when they jumped and be able to make the fireball sound too and maybe a few others. So I took a Wii Nunchuck, an arduino, a set of portable speakers and a birthday card to make this.<br />
<br />
The Wii Nunchuck has an accelerometer in it so I used that to tell when they jump and also for them to control the rest of the sounds. The Nunchuck is connected to the arduino using an adapter that you can make or buy so you don't have to cut the cable.<br />
<br />
For the sound recording and playback I found a birthday card that you can record 4 sounds on and playback the sounds by pressing each button. After tearing the card apart I found that it ran on a 3V battery so I used an <a href="http://www.sparkfun.com/commerce/product_info.php?products_id=9220">arduino pro mini 3.3V</a> for one and an <a href="http://www.sparkfun.com/commerce/product_info.php?products_id=9712">arduino FIO</a> which is 3.3V for the other. This way the arduino could directly control the sound board and power it too.<br />
<br />
I have an instructable I made for this <a href="http://www.instructables.com/id/Mario-Bros-costumes-with-sound-effects/">located here.</a><br />

<br />
<a href="http://1.bp.blogspot.com/_jfvHlbYSxMQ/TK1NU_0IZEI/AAAAAAAAEAw/klA4PABzyAU/s1600/IMG_0196.JPG" imageanchor="1" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" height="320" src="http://1.bp.blogspot.com/_jfvHlbYSxMQ/TK1NU_0IZEI/AAAAAAAAEAw/klA4PABzyAU/s320/IMG_0196.JPG" width="239" /></a>Last year we asked our sons what they wanted to be for Halloween and they both wanted to be fireflies so of course that was what they were going to be. It went without saying that they had to light up so my wife started working on the costume and I worked on the lights. Of course there wasn't much time until Halloween so it had to be pretty quick and easy.<br />
<br />
<br />
<br />
<br />
<br />
<br />
<br />
<br />
<br />
<br />
<br />
<br />
For each costume I started with a cheap high powered LED flashlight and took out the LED assembly.<br />
<br />
<div class="separator" style="clear: both; text-align: center;"><a href="http://3.bp.blogspot.com/_jfvHlbYSxMQ/TK1OuEwD6VI/AAAAAAAAEA0/S6XVRT94oHI/s1600/IMG_0616.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="200" src="http://3.bp.blogspot.com/_jfvHlbYSxMQ/TK1OuEwD6VI/AAAAAAAAEA0/S6XVRT94oHI/s200/IMG_0616.JPG" width="149" /></a></div><br />
Then I took 2 AA batteries and put a piece of jumper wire at one end with some foam tape to hold it in place. On the the other end is the wire that goes to the battery connector and to the LED assembly. I soldered the wire to the LED assembly leads.<br />
<br />
<div class="separator" style="clear: both; text-align: center;"></div><div class="separator" style="clear: both; text-align: center;"><a href="http://3.bp.blogspot.com/_jfvHlbYSxMQ/TK1PpqNeXPI/AAAAAAAAEA4/rBYx7Mz4cl4/s1600/IMG_0617.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="148" src="http://3.bp.blogspot.com/_jfvHlbYSxMQ/TK1PpqNeXPI/AAAAAAAAEA4/rBYx7Mz4cl4/s200/IMG_0617.JPG" width="200" /></a><a href="http://1.bp.blogspot.com/_jfvHlbYSxMQ/TK1Pwi2dplI/AAAAAAAAEA8/L45ApcFbbWc/s1600/IMG_0619.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="148" src="http://1.bp.blogspot.com/_jfvHlbYSxMQ/TK1Pwi2dplI/AAAAAAAAEA8/L45ApcFbbWc/s200/IMG_0619.JPG" width="200" /></a></div><br />
<br />
To make them able to light the lights when they wanted to I soldered a tiny switch and put heat shrink on it. I used the battery connector so the switch could be ran inside the sleeve of the costume and be removed from the light and the rest of the costume without having to pull the wire and switch out.<br />
<br />
<div class="separator" style="clear: both; text-align: center;"><a href="http://4.bp.blogspot.com/_jfvHlbYSxMQ/TK1R2vA1a9I/AAAAAAAAEBA/b1uQH9H6w9Q/s1600/IMG_0621.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="149" src="http://4.bp.blogspot.com/_jfvHlbYSxMQ/TK1R2vA1a9I/AAAAAAAAEBA/b1uQH9H6w9Q/s200/IMG_0621.JPG" width="200" /></a></div><br />
Here it is assembled. I don't have pictures of the rest of the costume parts but for the firefly light I cut out a sort of oblong half circle shape from thick styrofoam and cut a hole in the middle for the light. The battery pack was stuck to the styrofoam with 2 sided foam tape. My wife sewed a bag from yellow fabric and to make it keep it's shape she put fabric interfacing on the inside.<br />

I was asked to make a sign for a friend and didn't like the router letter templates available so after doing a little research on the internet I found that you could build a CNC Router. It was a fun project to build and I never get tired of watching it move. Anyway, the sign may have taken a bit longer but it looked really good when it was done.<br />
<br />
The limit switches still aren't hooked up but I did make sure the E-Stop button works. I really like the Big Red Button I found at <a href="http://www.gatewaycatalog.com/">Gateway Electronics</a>, it just makes it look more like a real machine for some reason. I also got the transformer for the power supply there. <br />
<br />
I went with the <a href="http://www.hobbycnc.com/">Hobby CNC</a> controller kit bundle which was very affordable but you have to solder it yourself and build the power supply. I am glad I did because this was my first big electronics project and it has been another hobby I have enjoyed ever since. <br />

So, we decided to start with a robot arm and I found drawings for one on <a href="http://www.thingiverse.com/">Thingiverse.com</a> I started cutting it out of 1/8 inch aluminum and realized pretty quickly that the time spent while the CNC mill cuts out the parts is spent removing the chips and spraying cutting fluid or else the aluminum welds to the end mill bit. After sitting for a couple of hours doing this I did some research and found that it wasn't that hard to setup a flood coolant system for the Taig mill. This lead me and my brother to build an enclosure to keep most of the coolant from flying everywhere and a tub, drain and filter system to get the coolant back to the sump. After a few hours of building and lots of on the fly re-engineering we ended up with this.</div><div class="" style="clear: both; text-align: left;"><br />

<div style="text-align: center;"><br />
</div>There are a few things I would like to change about it and a few things I will just live with but overall I am pretty happy with it. I had a pretty good idea of how to build it but as things went together I saw some problems with the design and just did quick things to get it working. I think I will at some point make a removable shield that actually mounts to the x-axis stepper mount and take down the table mounted shield on the right side.<br />
<br />
I had seen a manifold to mount the coolant hose to the mill head at <a href="http://www.cnczone.com/forums/showthread.php?t=48196">cnczone.com</a> and so made something like that. It was my first real part that I made manually with the mill. It was pretty fun but I will probably do most things with the CNC.<br />
<br />
<br />
<div class="separator" style="clear: both; text-align: center;"><a href="http://3.bp.blogspot.com/_jfvHlbYSxMQ/TIx5YUGj_KI/AAAAAAAAD_Q/n66lDQ7mI1o/s1600/IMG_0508.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="http://3.bp.blogspot.com/_jfvHlbYSxMQ/TIx5YUGj_KI/AAAAAAAAD_Q/n66lDQ7mI1o/s320/IMG_0508.JPG" /></a><a href="http://3.bp.blogspot.com/_jfvHlbYSxMQ/TIx5fdEfWSI/AAAAAAAAD_Y/K1DdNPlXlfo/s1600/IMG_0514.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="http://3.bp.blogspot.com/_jfvHlbYSxMQ/TIx5fdEfWSI/AAAAAAAAD_Y/K1DdNPlXlfo/s320/IMG_0514.JPG" /></a></div><br />
So this is the difference between cutting without flood coolant and cutting with.<br />

Here is the new robot arm, just got it moving. It is based off of <a href="http://www.thingiverse.com/thing:2433">http://www.thingiverse.com/thing:2433</a> by <a href="http://jjshortcut.wordpress.com/">jjshortcut</a>. It is made from 1/8 inch aluminum cut out on my <a href="http://www.taigtools.com/mmill.html">Taig CNC Mill</a>. Halfway through cutting out the parts I had to stop and build an enclosure and flood coolant system for the mill but that's another post... It is controlled (currently) by a Wii Nunchuck connected to an Arduino which controls a <a href="http://www.pololu.com/catalog/product/1352">Pololu Mini Maestro 12</a> servo controller.<br />
