Commodore 64 emulator for the PSP

3Excellent reason to roll back any PSP, a Commodore 64 emulator! – “64psp began life as an experiment to learn how to program the PSP. No PSP C64 emulators existed at the time and the Frodo source code appeared to have a gentler learning curve. A PSP port of VICE is also in progress. Both emulators have their plus and minus points, so why not try both?” [via] Link.

Breakout dock – iPod hello world

Breakout dock – iPod hello world

Blog Dec 21, 2005 0-35Image1Steve writes in with his progress on making an iPod breakout box with some new BASIC stamp action – “Work on the iPod breakout dock continues, and I have achieved reletively painless interaction with a BS2 microcontroller. This simple starter circuit has a single push button, an LED to let me know I am actually pushing the button…This small step, along with the iPod code generator I released previously, opens the doors to more complex interaction. In my case, there will be another device attached downstream, but that will have to be explained at another time.” Link.

HOW TO – Make a pedal powered air compressor

HOW TO – Make a pedal powered air compressor

PedalHere’s a great how to on Instructables on making a pedal powered air compressor, Aaron writes – “replace the electric motor of an air compressor with modified bicycle drivetrain. pedal. keep pedalling…use the existing motor mount to install an axle with one fixed cog and a belt pulley. You’ll need bearings. try a 1/2″ axle with radial ball bearing cartridges. make the bearing housing out of a slotted tube that has a drilled out nut and a regular nut to allow a bolt to tighten the tube around the bearing….” Link.

The Elevator Music Box

The Elevator Music Box

ElevatorGreat (old) project from Rocketboom’s Andrew – “This project was designed to create an isolated box which can be placed inside of an elevator to play dramatic sound designs based on the direction and altitude of an elevator. A microprocessor chip is stamped with conditionals to determine the location of the elevator based on barometric pressure and then pulses are sent to trigger an mp3 player which, when amplified, plays out from a complex set of musical relationships to create a dramatic and playful experience for the unassuming passengers.” Link.

Laser beam detection with a serial port…

Laser beam detection with a serial port…

BeamGreat how to on detecting a laser pointer “break” using a serial port – Chard writes “Ever wanted to make your own laser beam security system. You know the kind they have in the movies, with dozens of lasers and the thief has to limbo through them. Well, I just made a simple laser beam break detector. My computer can now tell when the beam is broken. The parts I used are: 5.6k resistor, photo diode, Digikey part #PDB-V107-ND, serial port from my PC…” Link.
