Resurrecting a PS3 controller that won’t charge

[SJM4306] grabbed a used PlayStation 3 from a game store that was going out of business. He got a pretty good deal on what had obviously been the floor model for a number of years. The one real problem was the controller that came with it. The thing was so filthy that he literally used gloves to disassemble and sanitize it. It worked just fine after that,until he discovered that it wouldn’t charge from the USB port as it’s supposed to. But he managed to replace the charging circuitry with some of his own.

When cleaning the insides of the controller he found there were numerous deposits of sludge which he attributes to spilled soda. This must have damage one of the chips responsible for charging because he was probing an unstable 2V rather than the regulated 5V which should be coming in on the USB lines. His solution was to desolder the USB port in order to separate its 5V pin from the PCB. He then etched a tiny board to host a MAX1555 charging IC. With the new hardware in place the controller is back in action.

Developing an animatronics platform

This Predator costume has an animatronic element in the shoulder cannon. It tracks the movement of the mask, aiming wherever the Predator gazes. [Jerome Kelty] was asked by a friend to help develop the costume and he ended up with an animatronics platform which can be adapted for many different uses.

Starting with an Arduino Pro Mini [Jerome] designed a host board which would breakout the pins of the Arduino and make it easy to connect and drive multiple servo motors. The board is powered by a 3.3v Lithium Polymer battery with charging handled by a MAX1555 that was included in the design. Check out the video after the break which shows off the Predator suit. Looks like [Jerome] got it right, and he’s also put the platform to use with an Ironman suit that has an arm-mounted missle feature.
