It’s actually a drawing machine. It’s built from
two stepper motors I salvaged from come old CD-ROM drives.
You can’t see it in any of these pictures, but in its
current incarnation, it has two pots each of which controls
the movement of one of the two motors: for moving the pen up
and down or left and right.
After sorta-kinda hacking together one RFID-based project, Benjamin Eckel decided that enough was enough, and went through the effort of documenting the process correctly.
Alan Stein built this $10 Arduino beatbox for his first Arduino project.
Using an Arduino Diecimila, breakout board, female PS/2 connector, and sundry components Ben has built an interface to connect a full-sized keyboard to his jailbroken iPhone.
I would like to know what is the best way to get started in this area of physical, interactive microcontrollers. Can some one point me in the right direction?
The other night at Maker Faire Rhode Island, I met up with Raphael. He had brought along these neat prototyping kits made from cigar boxes. I asked him about why he made them and what he does with these mobile prototyping platforms.
The last time we covered this neat die reading machine by Steve Hoefer, he had a very nice design that was starting to be able to determine the number of a die placed on it. Well, he swapped out his problematic photoresistor sensors for an infrared emitter/detector-based scheme to produce version 2, which he claims works with almost perfect accuracy.
