Wemos as ISP
Wemos as ISP is an interface card that plugs into Wemos mini board ESP8266, to allow the programming of 8-pin ATtiny 25/45/85 controllers and 14-pin ATtiny 24/44/84 controllers
Hardware
The electronic board project files are found here:
https://github.com/Green-bms/Wemos-as-ISP/tree/master/Wemos%20as%20isp/Kicad
To make or buy the card, the gerber files are here:
https://github.com/Green-bms/Wemos-as-ISP/tree/master/Wemos%20as%20isp/Kicad/export
Software
The sketch to upload to the Wemos Mini card can be found here:

Test circuits
To test the correct programming of the ATtiny microcontrollers I created two test circuits for ATtiny85 and ATtiny84. The wiring diagram is here:
https://github.com/Green-bms/Wemos-as-ISP/blob/master/Attiny%20test/Electrical%20drawing/Attiny%20test%20circuits.pdf The Arduino IDE sketches to load into the Attiny microcontrollers are here:
