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.

This is the micro:bit. It is a pocket sized computer system with motion detection, a built-in compass and Bluetooth technology that can be used to learn programming and electronics.

This is a CNC 3018 Pro router. It can be bought for around 150 euros from various online resellers. It comes unassembled. In this tutorial I will first do the unboxing and then share with you my challenges during the assembly of this CNC router.

What you see here is a Commodore 64 cartridge that I have created by sticking an EPROM and some other components on a breadboard.

A while back I also made a prototype for C64 PLA chip replacement, but I never did any further tests and completed the project. I thought that it was time to do some more tests on the chip. But will it pass the tests? Let's find out...
