New Homepage |

Hello,
after a long period it is time to redesign this homepage. I had no time left to keep this site up to date the last couple of months, but now I really want to see this site on a new level.
Therefore I will work offline to test the new ideas and layout on my offline-server.
Good ideas and suggestions are welcome. |

Mechanic's Toolbox Software - Must have item !?! |
|
|
|
"You get 41 software programs designed to make your job as a mechanic easier. Smart Tools with over 3,526 photographs, 200 catalogs and manuals, 11 videos, and 3 E-books all in one software package. You spend less time looking up information than the old paper catalogs."
I had a close look to this software and it is greeeeeat. This SW helps me to save time during my development ingeneering. Better way to use mechanics toolbox instead of programming my own SW or using different excel sheets.

Required Voltage - almost reverse engineering |
|
|
|
Not sure which voltages I need for this project, but my thoughts were DC 5 and 12 V are always good. Additional I would need a +10 and -10 DC for some OpAmps. As I mentioned earlier I would like to use parts I have already, therefore Instead of building a low voltage power supply I modified a power supply from an old broken DVD player which I found during my search for an suitable transformer. After Ithe replacement of the broken voltage controller 7812, a 2SB2001 transistor and two diode I got a working powersupply with 3.3V, 5v and 12V. It still needs some minor modifkation to get a + and - 10V DC.
As you can see on the picture above it is build with common parts; very easy to do some custom work on it.
The only detailed circuit diagramm I will do is the part for the power-on switch to turn on the transformer (system works like the ATX-Standard). The main power switch will turn on everything but not the isolated transformer. The reason for that is, that the TIAT will have two 220V outlets and both outlets are protected by a fault current protection switch. One normal and one is the isolated 220V outlet. The isolating transformer is going to be turned on separately by it's own switch (system is like a ATX power supply).
