This is a version of the Tea Gallows (see https://www.thingiverse.com/thing:2630698) working with an Attiny84 on a onesided PCB made with Eagle. There are three printed parts which are different:

bottom_PCB.stl, top_PCB.stl, panel_PCB.stl, knob.stl

The necessary Eagle-file for making a PCB is "tea_gallows_attiny84.brd"

The bascom-file for programming the Attiny84 is "tea_gallows_attiny84.bin"

You need the following electronical parts for the PCB:

(Programming adaptor for the Attiny84)
