Veroboard-based USBtinyISP (solder side)
The solder side of the finished product consisting of an ATtiny2313 microcontroller, a 74HC125 tri-state buffer, a type-B USB socket, the 10-pin ISP connector and a handful of discrete components. With the exception of the red wire running between the USB socket and the ISP port, the red wires carry the programming signals, the blue are there to reverse the order of the USB signals, and the black wires are ground. (See decarchive.org/~prd/2009/11/a-veroboard-based-usbtinyisp-... and www.adafruit.com/usbtinyisp for more details.)
