PSP analog stick part 2


I’ve been getting some help with How-To’s over at engadget. One of our favorite hardware hackers Ben Heckendorn put up part two of his analog joystick PSP mod. When he showed me the original I was surprised at just how simple this mod is. Part one showed off the wiring, while part two puts it in a clip on enclosure. Who else would strap a jerky tin to his PSP?

LED sensor solar tracker


More of my EV kick coming through. A solar tracker is used rotate a solar panel to get optimum energy from the sun. This one uses LEDs as the light sensor and mosfets to drive the output to rotate on a single axis. He even reduced the duty cycle on the fets so no heatsink is needed. Mounting in a peanut butter jar keeps the circuit dry and allows the sun to shine through. (The designer sells these, but has circuits up on the site)
