Building IR peripherals for the PSP

top

C.K. has always been the goto guy around here when it comes to testing out new PSP hacks. Firstly because he was writing a PSP Hacks book and had plenty of hardware laying around; Secondly because it kept me from having to field questions in the excessively long firmware threads. The book has been published and O’Reilly has posted some sample chapters. Thomas Novotny wrote this chapter on interfacing the PSP with peripherals over IR (PDF). It’s similar to our previous entry, but has better documentation and doesn’t assume that you are experienced with microcontrollers.

MF2006: Human powered Ferris wheel

There is a set of bike pedals attached to each seat. The chain on each one drives a sprocket attached to the chair’s pivot point. Spinning the pedals tilts the chair and the entire frame reacts by rotating. They only had one set of pedals attached, but it was more than enough to spin the wheel at a pretty good clip. It did look like some damping on the chair pivots would help, since the chairs would swing pretty wildly. I’m sure adding two more chairs would help as well.

MF2006: Difference engine

difference engine

I was pleasantly surprised to find Tim Robinson’s difference engines at the Maker Faire. Both machines are based on Charles Babbage’s designs and built out of Meccano. A difference engine is a mechanical computer for tabulating polynomial functions. You can read more about the construction on his site. More photos: one, two.
