            <title>Automatic Wire Cutter and Stripper</title>

(a video of it in operation: <a href="http://www.youtube.com/watch?v=F2O7kGE34EA" target="_blank" rel="nofollow">youtube.com/watch?v=F2O7kGE34EA</a> ) <br />
<br />
<b> Why? </b><br />
To create lengths of wire that fit perfectly into an electronics breadboard. (we produce kits and you can only hand cut and strip so many wires before you go crazy)<br />
<br />
This is also the first item in a concept <a href="http://oomlout.com" target="_blank" rel="nofollow">oomlout.com</a> is working on dubbed "open manufacturing". (more to follow)<br />
<br />
<b> How?</b><br />
It breaks down into three parts<br />
1. <b>Wire Feeder</b> - This feeds the wire in measured lengths forwards and backwards (uses a stepper motor)<br />
2. <b>Wire Stripper</b> - This runs an exacto knife blade around the insulation of the wire twice. (uses a small servo motor and normal sized servo motor)<br />
3. <b>Wire Snipper</b> - Snips the wire at the end. (uses a pair of wire cutters and a cheap handheld drill motor)<br />

            <title>Open Source Robotic Arm</title>

            <description><![CDATA[<div style="margin: 5px;"><a href="http://www.thingiverse.com/thing:387"><img src="http://thingiverse_beta.s3.amazonaws.com/renders/99/26/3e/d4/e2/3381047684_066ffe8f56_o_preview_large.jpg" alt="OpenSource Robotic Arm" class="render" style="width: 240px; height: 180px" /></a><br/>OpenSource Robotic Arm</div><div>Perhaps one of the funnest projects we have attempted around the .:oomlout:. offices. A five degrees of freedom robotic arm. While we have spent many hours twisting knobs to move pop cans from one point on our desk to another sadly it has not progressed much further.<br />
The main reason for this is the sum total of math knowledge around the <a href="http://oomlout.com" target="_blank" rel="nofollow">oomlout.com</a> offices is about 4 (don't ask us to show our work on how we calculated this) so inverse kinematics is well beyond our reach.<br />
<br />
We are releasing it in an imperfect form in the hope that the clever Thingiverse denizens will be able to make it better.<br />
<br />
Why this isn't quite ready for sale:<br />
-We lack any inverse kinematics program which makes moving the arm intelligently nearly impossible.<br />
-Without software limits on the servos it is capable of stripping the low cost hobby servo motors (this is alright for testing as they are only five dollars) (we have stripped two in the life of our arm and both happened when we were asking it to do silly things) (this can be fixed by upgrading the servos)<br />
-We haven't completed the 3d model or assembly instructions just yet, but by studying the photos it is possible to assemble. (think more jigsaw puzzle than lego set)<br />
-The gripper, lets just say the gripper needs a little work.<br />
<br />
That said it is an amazingly fun toy to play around with, and a good starting point if anyone has ever had a desire to make the perfect robotic arm (it is open source so you'd be free to make and sell your own)<br />
<br />
(shameless plug)<br />
