Tea Gallows with Eagle PCB

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)

ATTINY 84A-PU: Atmel AVR 8-bit 8 KB, DIP-14

R1 – R9: protective resistor, 150 Ohm, SMD Size 0805

Led1 – 8: 3mm, normal LEDs without internal resistor

Ceramic capacitor: 100nF, SMD Size 0805

Tactile switch: length of the actuator: ~6mm, such as (https://uk.rs-online.com/web/p/tactile-switches/4791435/)

Photomos Relais: Panasonic, AQY212S (https://www.buerklin.com/de/photomos-relais/p/29g8781)
