To give some more context around some of the design decisions, I'll do a
quick summary of the power supply design process here:
A main goal was to only use off-the-shelf magnetics. The transformer was
chosen to have the highest available HV winding magnetizing inductance, to
limit the reactive
I know I'm a bit late in following up on this, but better late than never!
I got caught up in life and other projects as usual.
I've put up some more photos and videos, plus some preliminary schematics

Actually, that code works well! I had a typo on a pin config. Seems to work
well! Very pleased. I hope you find that snipped of code useful.

Jörg,
This is the code that I am using with DAC 4822 (similar to 4922 but with
internal ref.). I can generate some nice sinewaves with 1V or 2V amplitude
with the Teensy 4.1 powered by USB data cable and output displayed on my
Rigol oscilloscope.
And of course, I can draw a circle.
I think
Pretty nice photos.
I like it too, to disable blanking and to see the painting beam.
I did some tests with the MCP4922, too, but it was too slow for me.
Mabe you've found a better way (code) driving it. If you don't mind, I'm
intersted in a code snipped and which lib you have used.
I ended up in
wow! while the technical details are all "greek" to me, the images look
amazing. I love the "artifacts" in them. I dont know how you took these,
but it looks awesome! I like it as it is! not sure how this looks like in

I do not like the Arduino IDE much. It should run on david's hardware, too.
Do yo you have build the hardware already?

@jörg,
No, I have not yet built anything. Just "scoping" out where this will take
me.

I was able to change to a Teensy 4.1 with a 2 channel 12 bit SPI DAC in my
latest version. I had to reduce the DAC rate by half. It looks just as good
as the old version. Of course, the DAC I chise is already unobtanium.

Hi, maybe a bit offtopic.
I've put some effort in using the teensy4.x to run the scope clock based on
david forbes one.
The teensy3.6 based one is running on my own hardware for a while.
But because of CPU shortage and the use of the teensy3.6 internal DAC's, I
was curious to get the stuff up
