Tea Gallows with Eagle PCB

thingiverse

This is a version of the Tea Gallows working with an Attiny84 on a one-sided PCB made with Eagle. There are three printed parts which differ: bottom_PCB.stl, top_PCB.stl, panel_PCB.stl, and 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". To complete the Tea Gallows project, you need several electronic components. Here's what you'll need: A programming adapter for the Attiny84. One ATTINY 84A-PU: Atmel AVR 8-bit 8 KB, DIP-14 microcontroller chip. Eight protective resistors (R1-R9), each with a value of 150 Ohms and an SMD size of 0805. Eight normal LEDs without internal resistors, each measuring 3mm in diameter. One ceramic capacitor with a value of 100nF and an SMD size of 0805. One tactile switch with an actuator length of approximately 6mm. The tactile switch you need can be found at (https://uk.rs-online.com/web/p/tactile-switches/4791435/). One photomos relay: Panasonic AQY212S, which can be purchased from (https://www.buerklin.com/de/photomos-relais/p/29g8781). One buzzer: KPX-G1203B-6400, available at (https://www.voelkner.de/products/209749/Magnetischer-Summer-Kpx-G1203b-6400.html). A Molex pin header for the battery connector, an SMD PicoBlade 1 x 2-pin connector: MOLEX 532610271, which can be found at (https://www.reichelt.com/us/en/Molex-multiple-connector/MOLEX-532610271/3/index.html?ACTION=3&LA=3&ARTICLE=186225&GROUPID=7981). A Molex pin header for the servo connector, an SMD PicoBlade 1 x 3-pin connector: MOLEX 533980371, which is available at (https://www.reichelt.com/us/en/Molex-multiple-connector/MOLEX-532610371/3/index.html?ACTION=3&LA=517&ARTICLE=186227&GROUPID=7981). Two Molex crimp contacts for the battery connector, a PicoBlade socket: MOLEX 500798100, which can be found at (https://www.reichelt.com/us/en/Molex-multiple-connector/MOLEX-500798100/3/index.html?ACTION=3&LA=446&ARTICLE=186235&GROUPID=7981). One Molex crimp housing for the battery connector, a PicoBlade 1 x 2-pin socket: MOLEX 510210200, available at (https://www.reichelt.com/us/en/Molex-multiple-connector/MOLEX-510210200/3/index.html?ACTION=3&LA=446&ARTICLE=186197&GROUPID=7981). Battery contacts with a plate size of 20 x 12mm, available at (https://www.amazon.de/gp/product/B00PZT080S/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1).
