What the world needs, is another VGA to SCART converter ;)
I based it on Tomi Engdahl's circuit, but added an MCU to enable the sync signal, when the horizontal sync is in range. Now I just have to convince the AMD GPU in my TV computer to output the correct signal...

Time for another project. I have close to zero spare time, so I really need another project ;)
This time it's a tube tester. I bought the minimum kit of just PCBs, the special transformers and a programmed PIC.
There's a lot of boards to assemble...

The second prototype - now enclosed. Soon I'll know if everything works. The boards work individually, but haven't been tested together 🙈

PCB coming up...
The audio part takes up little space. The power supply and control section takes up most of the space :)
The tubes will be connected with wires. PCB mount sockets for European 30's tubes are not readily available ;)

Been working on a very simple control panel for my latest project. It's just an MCU, a rotary encoder, an IR receiver, a pair of displays and a pushbutton. I would normally use a display driver of some kind. But with 42 I/O lines, why not drive the segments directly?

The new operating points of the input stage, did improve matters - slightly...
4% THD at 1W output isn't exactly great. But compared to 0.14W at 1% THD it is an improvement. Distortion halved in round numbers. So it's not just the input stage that was causing the issues.

Building small stuff tonight ...
Turned out the linear pre-regulator needed more cooling than just the copper area on the board. So I soldered on a small heatsink.

Tired of not being able to find LPs at night, so I'm building lights to install above the shelves. Warm white LEDs (I hope), and 3 brightness settings.
