"I built a pick and place machine so I could build up my Motobrain project easier. I used MDF for the platforms. 12mm rail and linear bearings for the Y and Z axis bearings. THK linear motion guide for the X axis. The Z axis is a piece of carbon fiber tubing attached to a piece of laser cut acrylic. The nipples on the tube are 3D printed."

"In about April of 2004 I started this binary clock project which was inspired by the Think Geek binary clock. I put the project on hold a number of times and finally finished it around October of 2004. When I started the project the TG clock was only available with red LEDs, and while it was definitely pretty cool, there were a number of things about it that bothered me."

"A reflow toaster oven and a simple laser cutter. Why a laser cutter? Using a reflow oven makes things easier, but we still have the problem of putting the correct amount of solder paste on the board. This can be done using a PCB stencil."

"A little time ago I made a robotic arm, without the gripper. So last week I draw a gripper that is compatible with a mini servo, I made two versions because I had to chose between two kinds of gears, straight and rounded. Because I first finished the straight gears version I milled this one first, but since there was a little play between the two gears I also made the second one, the one with the rounded gears."

"This project is a USB based computer status display. Downloads at the bottom of the page…The firmware uses microchips USB stack. The files included in the USB folder are from the ‘Microchip Libraries of Applications’ I used version v2012-08-22 of this…The support application was written in C#. Some things of note…the file HIDInterface.cs is an invisible form."
