Making PCBs Using the Toner Transfer Method
I've been making a bunch of breakout boards recently using the toner transfer method. I think I've finally nailed the procedure such that I get good, repeatable results. The following wiki article only explains how to do the transfer, generating the layout and etching is pretty straightforward (links are provided to some good guides). I've [...]

Using an HD44780-based display with a TI MSP430 microcontroller
 ??I've recently been tinkering with TI's MSP430 line of 16bit microcontrollers thanks to the crazy-cheap MSP430 Launchpad development board. For less than $5 you get a USB programmer, an in-circuit debugger (that works with GDB!), and a USB to serial converter. There's pretty decent Linux support for these chips, much like with Atmel's AVRs you [...]

Simon Says
In an effort to learn more about the capabilities of Atmel's range of "tiny" AVR microcontrollers I decided to build clone of the popular "Simon Says" game using an ATtiny45. The gist of the game is that it blinks out a pattern using the LEDs and you simply have to key in the same pattern [...]

My Alarm Clock
For the longest time I've been using an old CRT television as my alarm clock. It was very simple, there was a sub-menu in the TV's setup menu that allowed you to set a time for the television to turn on. This worked great for many years until I got rid of the TV. I [...]
