If you have followed my channel, you would know that I'm in love with the Attiny85 microcontroller and that I've built a lot of projects with it.

To program the Attiny's I've built a shield a long time ago on a piece of perf board with an IC socket, and that has worked fine till now.

Since the socket started to become loose from the repetitive removals of the microcontrollers and I needed something where I can program more than one ATtiny at a time, I decided to build a new programmer.

The new programmer is made on a custom PCB that was manufactured by PCBWay and it has a quick-release socket in the middle.

The socket has 28 pins (14 on each side), so 3 sections of 4 pins are used to connect multiple Attiny's in parallel so the same program can be flashed on all three at once.

Besides the quick release socket, the programmer uses very few other components so it is a perfect project for anyone looking to try out the Attiny microcontrollers. 

You can check out the shield in action in the video below.
