ATMEGA8

Before the Arduino and ATMEGA328 really hit the scene, this development board was designed and constructed to explore and test peripherals of the Mega8 series of 8-bit micros. It features two analog input photometers, RS232-USART transceiver, LED bar-graph, four tactile push button switches, on board regulator and I/O breakout headers.

ATMEGA16

Like it's little 8-bit brother, this board was designed for testing and software development purposes. It features two analog input potentiometers, RS232-USART transceiver, LED bar-graph, DIP-switch digital inputs, LCD header, on board regulator and I/O breakout headers.

PIC 16F876A

Similar to the AVR development boards, this PIC board added general purpose op-amps for two analog channel front-ends, as well as more robust connectivity.

Acrylic Enclosure

A cheap resistor "decade box" from eBay was purchased and it seemed it could benefit from quick enclosure. Sorry, no design files here - one off on a vertical mill!
