I’ve been some time off with Covid during the first weeks of January and slowly started again with sports. Well, had some problems with breathing but finally I am fully recovered. Unfortunately, Frank had to wait quite a while to get his CD555 (the one from the unboxing video) finished, but now he got it back – fully recovered and […]

Happy new year – with new belts
First: I wish you all a happy new year. Let’s hope for peace and healthiness. Since I still had problems with the belts I was using from eBay I now found another manufacturer. After several months of usage I noticed that one belt, that got already replaced, failed. Not sure if it was a quality issue of just one belt […]
On cooling: A control unit for a fan
When designing the rear plate I kept some cuttings to place a fan. Initially it was designed for my new CPU board to control the fan with a sensor to measure the temperature. However, due to some requests I decided to design a small pcb to add a wee fan controller that fits into the given cuttings for the – […]
Attempts to improve the cooling
One of the main issues of the CD555 is the produced heat. Philips added a thick rear plate and the handle for the battery pack represents a kind of a heatsink. Mounted onto this heatsink are the two amplifier ICs and a transistor to generate 15V out of 38V. The difference of 23V will be transformed into heat. In addition […]
New Micro-Processor Board running inside the CD555 for the first time
Finally, after endless months of development Revision C of the new Microprocessor Board is running inside the machine to control the tape and the CD-Player. Let’s not talk about Revision B since it still had some faults. However, it has been a long way and took many fails and expenses to come this far. Some days ago, for instance, I […]
New 3D-Printer Anycubic Photon D2 with DLP
I spent the last weeks getting one of the 8 gears I bought at eBay working. But I failed., what a waste of money. Not only are they built from the hard material, the whole is not centred and also the size does not match. The tape stops to wind and the running capstan causes tape jam. So I am […]
New MicroController Board Rev.C running inside the CD555
After a while there has been some progress regarding the new Micro-Controller Board. Let’s skip Revision B since it still had some issues and move forward to revision C. This revision finally made it inside the SoundMachine. Everything fits and is working although I have to change the position of connectors for easier assembly. It is not possible to get […]
Progress of new cooling possibilities….
Well, after I lost this week the second time the decoder panel of the CD-Player due to heating issues, I’ve got a “little bit” angry. Although I use this sound machine everyday it should not fail every six months. I guess it is time to improve the cooling of the sound machine. Originally, the aluminium panel at the rear side […]
New office furnitures…
Earlier this year I already replaced the shelves and drawers. Now I got the hand on some second hand professional office tables and drawers. With a little bit of luck they all fitted into the office. I am really happy about the new space and the positions of the oscilloscope and other devices is now much better than before. I […]
New soldering iron
The last weeks had been very hot and I have not had any time to continue my projects. However, it was time for a new soldering iron. Even when es SMD parts are relatively large in the format 1206 they are way too small for me to handle. Seems I am getting older… As solution I ordered a new Ersa […]
