To connect an old joystick, like the Competition Pro, to a modern PC, you need an adapter. The old joysticks from home computers have an interface that today's computers don't have anymore. On the Internet you can find numerous building suggestions. Today I would like to present a very interesting adapter.

Most people who deal with Commodore hardware will also like the term "ZoomFloppy". I've been using this hardware for some time, too, but I've also been bothered for so long that the board is extremely large and unwieldy. The ZoomFloppy is also delivered as a naked board, without any case. This made me shrink the ZoomFloppy.

The EasyFlash³ module is still a popular accessory for the Commodore C64. And meanwhile you can get the single components from Asia for little money. However there are here and there some stumbling blocks. Today I would like to give a few tips about the problems that can occur with the CPLD and how to fix them.

In the old quote "The most devout cannot live in peace if it does not please his evil neighbor" there is sometimes more truth than one can love. Like a simple offer to help another person suddenly almost became a blood feud...

Commodore floppy disks with an IEEE-488 interface have unfortunately become very rare in the meantime and are sometimes sold at top prices. At that time Commodore brought the model 2031 onto the market. It was basically a 1541 with modified electronics. The differences between the two models is extremely small.  At that time, this already led some resourceful hobbyists to take a close look at the circuit diagram of the 2031 and to make a corresponding adapter.

For many years Seeedstudio has been known as a development forge and shop of all kinds of fine electronic gadgets and accessories, making the heart of the maker beat faster. For some time now a board service has also been offered. This is what my little test is about.

"Planning is half the life" - Surely everyone has heard this saying before in his life. And he is not so completely wrong. Where one can act in the small perhaps still on it loosely, with larger topics a planning becomes inevitable.

As I had already written in the first part, only now did the whole thing begin to take on greater proportions.

I had presented my little project in the Forum64.de.

Surely one or the other JLCPCB is a term. It is about a quite large Chinese circuit board manufacturer. Until recently, you could upload your own printed circuit boards in Gerber format at a very reasonable price there, and a short time later you received the printed circuit boards by mail.

Since I also work a lot with SMD, I often order the matching stencil with it. All in all, this has always been quite inexpensive.

Today there are steamed circuit boards... Or how to make life easier with condensation soldering.
No, there are no recipes presented now, or cooking is discussed, although the latter is not quite correct. It is about a rather old process of reflow soldering: vapor phase soldering or condensation soldering.

At the beginning of the 1980s, this process was still being discredited and forgotten because of the use of chemicals that were not exactly environmentally friendly. Only with the development of perfluoropolyethers did this process experience a new renaissance.

Like that sometimes is. You have a nice idea for a small craft project, and in the end the whole thing becomes a mammoth task.

Such stories usually start with a "Actually, I just wanted to...", maybe paired with a "just fast...". And in this case I actually only wanted to make an existing circuit board smaller. There was not even a deeper sense behind it, but only the fun of tinkering.

In this case it was about the so-called ZoomFLoppy:
