Electronics hobby blog

In this blog series, I will cover the build of my Prusa MK3S 3D printer clone. My goal is to reduce the costs of the original while keeping the quality as high as possible.

In this blog post I am going to dive a bit deeper into the ezPLA chip, investigate the reason why it does not work in all C64 machines and then try to fix it.

A while back I made a prototype of a Commodore 64 PLA replacement chip in FPGA and covered this extensively in this blog post.

My Mac Mini from late 2012 started to get slow due to constant reads and writes of the mechanical hard disk. It was time to upgrade it with an SSD drive. I took some pictures during this upgrade to share in this blog post.

A while back I created a prototype board for the PLA replacement chip for C64. It was time to make a PCB out of it. In this blog post I will describe the steps that I did to design the PCB using KiCad and manufacture it using PCBWay prototype service.

Teensy 4.1 can be upgraded with up to 16 Megabytes of PSRAM. Here I describe the process.

SIDKick is yet another SID replacement solution for your C64 that is powered by Teensy 4.1 board. It is completely free and open source based that you can build yourself.

After collecting all the components needed for the Atari board it was finally time to solder them. But what are the chances that the project would work on first attempt? In my case it didn't and I will describe here my process of troubleshooting.

This blog post takes a closer look at the Macintosh Plus and show how to create a System Boot floppy disk. Besides that it also shows how to get some software to run on this computer.

In this blog post I will be taking a closer look at the WIO Terminal and making a small game using ArduPy which is a combination of Arduino and MicroPython.
