Machine tools from scratch wiki
stewart platform simulator I wrote for EMC2, the prototype "hextatic" still in its box, and an illustration for the Buckminster Fuller Challenge entry
some cad drawings showing one of hextatic's pulley housings, and the semi-finished product
a "resynthesized" klimt painting...
a stick font engraving program, based on the hershey fonts
I made this metalworking lathe from scratch, using only a drill press, plate glass for a flat reference surface, and backyard foundry. It is in the process of being refitted with servo motors for CNC
me giving a demonstration of pouring aluminum into styrofoam "molds" which are vaporized and then burn off, leaving an arbitrarily shaped casting
3dspiro5.py
a poor quality CNC foamcutter assembled from trash, and associated useless art objects
moth demonstrating computation in nature with its aerodynamic shape and cellular-automata-like markings, or silly human projecting on the world? your pick
I helped build and maintain a community accessible woodworking/welding/electronics shop, and garden
papercraft with Blender, as an example of computer aided manufacturing that anyone could do
ideas for clanking replicators or just cheap machine tools: hexegrity and a laminated pancake motor design
illustrations done in Inkscape for EMC2 of the basic machine types and interface cards
board layout done in Eagle for openservo.org's "call for entries" - I thought they looked sorta like faces
wrote the gait sequencing code for the tiptoes robot, which was a friend in Australia's project
CAM algorithms - offseting polygons (well, not really - it's difficult!) and a curve-length-parameterized spiral, which prevents path planning queue overflow at the center
servo.c draw_encoder.py
a DIY "smart servo" with PID control running on an AVR in fixed-point, and printed optical encoder wheels
graphical representation of my "Guinea Pig C" lifelog data: blue is sleep, red internet, green food, yellow programming, etc
I was teaching a series of workshops on AVR microcontroller programming for the IU robotics club, and we needed lots of chip programmers. So I made some, based on designs from ladyada.org and modified for easier toner transfer etching. A circuit board assembly line spontaneously formed when I brought in the spare parts one day!
