Yet another fabable ISP (In System Programmer), this time based on the FabTinyStar board, which was specificly designed to be made in a FabLab.

It includes a few extra features such as a target power led and switch, a reset button and a led on the SCK line to indicate communication in progress.

The original documentation (downloads too) can be found at: http://fabacademy.org/archives/2015/doc/projects/FabTinyStar/

In this guide we'll be using the 5V version 0.3 (Bas).


Unfortunately this documentation isn't as polished as I want yet, but all the information you need to make one yourself should be here.


Some stuff you're going to need...

The vusbtiny_firmware_fabtinystar.tar.bz2 archive already has the modifications made to it and includes a precompiled binary firmware for convenience. With this you can skip the step "obtaining the firmware" in the "programming" chapter.

Alternatively you can download the original sources with a fresh copy of the vusb driver and build them yourself as described in the "programming" chapter.
