ZIF socket atTiny programmer

Hey. First post here on the page.
This project is fairly simple but i find it useful.
I did this early December after i found an orphaned 20pin ZIF socket at work and figured i wanted to program 2313’s.

Zifsocket programmer
It is just a permanent Arduino ISP programmer with 3 4052 multiplexers to switch between the pinouts for the attiny85,84 and 2313.
The 4052 address pins are pulled down and set with a sp3t switch. I’ve seen shields using 3 sixway dipswitches. this seemed impractical to me.

My nano is mounted on headers and not modified in any way. I might need it for something else one day.
The leds are heartbeat/error/programming indicators

Zifprogrammer underside
Not as pretty underneath, i used this stripboard that is cut every three holes. i find these practical when working with ic’s.

The predecessor was an old shield with ic sockets for 85 and 84.

Nest step adding a six ISP header so i can mess with ISP programming of atmega8s and other avrs by converting the arduino files to hex and programming through AVRdude
