Welcome to M&M's DIY Electronic Site!



This site is devoted to electronic gadgets which are:

  • fun to build
  • too expensive to buy or
  • just cool to have.


Let's see what we have. So far, the biggest project is the AVR Light Controller for LiPo-powered Halogen Bike Lights or similar use cases.

Then, we build an USB controller for IKEA DIODER LED stripes.

Also, we recently wanted to charge our iPhones in the car, which led to some googling and the iPhone Car Charger Mod.

Neither a hack nor a gadget, but related: a User-space Java Bluetooth (JSR-82) Keyboard Driver.
