See how I've made my own PCB for the well know circuit of ATtiny85 Arcade game. Here you will have the schematic, part list, step by step of soldering components, how to burn bootloader and how to upload codes for different games to the ATtiny85. I know this is nothing new and you have more here on the original GitHub post. But I hope you will learn something new.

# 1. Overview #
TinyLoad is a simple electronic constant current dummy load. The ATtiny85 measures voltage, current and temperature of the heat sink, calculates power, energy and battery capacity, controls the fan and displays all relevant data on the OLED. The button is used to switch between power/restistance and energy/capacity display.

Simple USB ISP programmer for Atmel AVR microcontrollers. More information can be found at https://dicks.home.xs4all.nl/avr/usbtiny/. Windows users may need to install a driver: https://learn.adafruit.com/usbtinyisp/drivers. Of course this is not necessary for linux and mac users.
TinyKnob is a rotary encoder with a USB interface based on the ATtiny45/85 and the V-USB software-only implementation of USB1.1 devices on AVR microcontrollers (https://www.obdev.at/products/vusb/index.html). The example code implements a volume control knob for PCs which works without installing any driver by acting like a generic HID device.
Simple USB-C Power Delivery Tester based on ATtiny45/85 and INA219. You can switch between different screens by pressing the SET button. Due to the internal structure of the USB-C cables, it may be necessary to change the orientation of one of the cable plugs.
