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 […]
Started with the development of a new uProc board
Well it has been a while since my last post. I have been off for a couple of months due to rehabilitation on burnout and now very slowly trying to get back to life… but that is another story. But let me introduce you to my latest project… After a successful reverse engineering of the CDM2 controller protocol and the […]
Markus Sound Machine finished
Finally another CD555 got rescued from the dumpster and except from recording to tape, everything works fine. We are going to have a look at the record function later on since I am off for a couple of weeks. I have also replaced the missing radio station indicator. Based on the original I rebuild it with the resin printer and […]
Create your own CD-Player around a CDM2
Another idea grow in my mind for a while… the plan to re-develop the faulty uProc board with the microcontrollers of the tape deck and CD-Player. I successfully replaced the tape MCU and added a better error handling and more features but always thought to use the MCU of the CD-Player as it is. However, there are a couple of […]
Replace broken parts of CD tray and buttons
Unfortunately some parts in Markus’s machine are broken and needed a solution. The soft eject gear of the CD tray was broken. The mechanism itself was ok but the brackets to hold it in place got broken. After some thoughts and several tries I came up with a printed bracket that holds the soft eject gear in place. It fits […]
CDM2 repaired
The first thing I liked to repair for Markus’s machine was the CDM2. The disc was not spinning and has not shown any signs of life. To avoid any possibilities of using a failed decoder board I was using my “modified” CD150 which has the connectors outside the case ready to be used with a CD unit for a better […]
New project: Markus’s CD555
Finally, there’s a new project on my desk. Markus found a cheap CD555 at an online second hand shop. Of course, unsurprisingly, it is not working. He contacted me to have a look at it and if possible to repair it… and here we are. The CD555 has some scratches and the speakers are badly worn. Some edge of the […]
Another interesting detail of the CDM2/29
Recently the CDM2 in Unit#4 failed to play. Hooray! At least something to work on 🙁 The Sound Machine right from hell. The CD was not spinning and the sound the motor produced was quite noisy. It was quite obvious that this is a mechanical issue. Even by hand I was not able to spin the motor. Unfortunately, this means […]
Another CD555 sold at eBay
Another non working CD555 showed up at eBay and got sold for 181€. Luckily the winner gets the original speakers which is not usual. Congratulations! In general it’s in a very nice condition. The winner contacted me, respectively Video #4, afterwards, but I am not able to answer since the comment on YouTube is not visible, even not for me. I just […]
