An undertaken electronic project does not always need a dedicated Arduino board. Sometimes it is sufficient to use separate Atmel ATmega328P chip and add some parts around it to make it work.

Visualisation of sound gives an extra dimension in the experience of music. The LM3915 chip makes it possible to easily create a circuit that can accomplish this task.

Important part in an electronic project is creating an enclosure for the parts. Without it, it is simply not finished. Luckily we now have 3D design software and 3D printers which are perfectly suited for the job.

Playing games on emulators is usually bound to using arrow keys on the computer keyboard or an analog PC joypad. This ruins all the fun. The right way to do this is of course using a real arcade joystick

Gotek floppy disk emulator can not be used on an Amiga computer without modding it. Luckily it is not hard to change the firmware on the device to be able to boot ADF images from an USB drive.

After I have bought this Amiga 500 computer, the cover was in very bad shape. The previous owner tried to retr0bright it, but it didn't work out as planned and there were a lot of spots.

Two old computer mice turned yellow over the years and needed some brighting up. To achieve this we are going to use the retr0bright method.

This vintage Canon parallel scanner needed some restoration and for that purpose it needed to be taken apart. It is a bit tricky as some of the parts are glued with adhesive tape and need to be detached very carefully. This small tutorial shows a step by step disassembly instructions of the scanner.

If you have old plastic cases that have turned yellow, you can restore them to it's original state just by using hydro-peroxide, some oxy powder, UV light bulbs and patience. In our test we will be restoring an old Canon flatbed scanner cover that had turned yellow

In this project we are going to create a simple BASIC program, then save it to the tape (which in our case will be a wave form on a PC) and in the end convert it to a TZX image file that can be run on a ZX Spectrum emulator like Fuse.
