Well, I had enough problem with soldering tinny SMD parts, especially when removing them. Sometimes I damaged the PCB when trying to remove SMD components or was unable to remove simple components like resistors from multiple layer PCBs. When I learned something during my 35 years work experience, then it saves time and nerves when you use the right tools. […]

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 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 […]
Welcome Unit #4
Some days ago I found another CD555 Sound Machine on an online flea market in Austria. Yes, call me crazy but I had to buy it. On the picture it looked as it would working, also the Lady who sold it said it is working. I was sceptical because this would have been the first unit I have seen which […]
The hardest thing…
when repairing this old machine is the cat. I am always searching for parts which are spread around the house. Very nice when you step on an IC, gives a nice pattern on you foot. Lego is for beginners…
Workplace update
During analysation of the second unit I noticed that I need a frequency generator to be able to measure the audio channels. Real measurements based on a connected music box will not lead to any success. I came up with a cheap Chinese frequency generator. It delivers accurate results and offers a lot of feature for its price. However, its […]
The workplace
Since I have not been active in the field of electronics for many years there are only a few tools left my from previous activity. That also includes my knowledge about transistors and other parts which I really need to refresh. Beside a voltmeter and an analog electric soldering iron, which requires new bits, no other tools are available. Rigol […]
