 +
| '''WS2811 LED strips & 8Mhz AVR'''
 +
Want to know how to drive a WS2811 led string from an 8 Mhz AVR? [[Driving the WS2811 at 800 kHz with an 8 MHz AVR|This page]] has the code and explains it. Works for Arduino too...

| '''USB 433Mhz transceiver for $3'''
 +
Cheap 433Mhz receivers and transmitters are ideal to communicate with your microcontroller, but can also be used to control inexpensive RF-controlled switches. If you've got $3, an ebay account and a soldering iron, you can now [[Cheapest ever 433 Mhz transceiver for PCs|control your light switches through a USB port]].

 +
| '''Digital FD-8 repair'''
 +
Roland FD-8 hi-hat pedals have a tendency to become unresponsive over time. Instead of trying to repair the internal film resistor, why not completely [[Digital FD-8 pedal|replace its guts with a small microcontroller]] for accurate control without wear and tear? If you think a microcontroller is overkill, we also have [[Roland FD-8 Issues: Hall Sensor Modification|an analog electronics version]].

| '''Breadboard AVR Programming Headers'''
 +
To celebrate the release of Vinnies [[Vinnies Definite Straddling Header‎‎|student-proof, straddling programming header]], we've finally gotten around to documenting the [[Evolution of breadboard programming headers|programming headers]] we use for AVR breadboard programming!
