Many moons ago, before I knew anything about Arduino, I bought a “minimum ATmega kit” from eBay, pretty much like this, DIY ATMEGA8 Minimum System Board ATmega48 ATMEGA88 Minimum System Board AVR Kit. It arrived, I built it, I put in in a box and forgot all about it until today, when I came across it.
But once you’ve made it how can you use it and what are the buttons for?

Following on from the keyboard gag being the reason for purchasing my first Leonardo, see My Arduino Babies and something useful to make with a ATtiny, see A tiny one, here is a self contained list of keyboard and mouse prank projects.

Found the first link, Buchla 100 system diy build, and went from there.
What is it? See The Buchla One Hundred Series
Buchla 100 Series Clones states:
I have found a 144, 111, 110, and a 194.

Metal Core Printed Circuit Boards (MCPCB) are used to keep high powered LED circuits cool, as the metal substrate helps dissipate heat generated by the LEDs.
However, they can also be used, as an alternative to FR4 PCBs, to create heavy, sturdy and funky PCBs for audio applications, especially if a thick 5-10 mm substrate is used (although 3.2 mm is the common maximum thickness – see below).
I got the idea after seeing this question on StackExchange: Custom/DIY Metal-Core PCB? However, MCPCB is really only useful for SMD components. Standard discrete components would need to be routed via the underside, and there would be a potential for short circuits caused by component legs coming in contact with the metal substrate.
