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

On Saturday,
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 t
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 a
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
"motion" but looks great in the stills... can you post some more? cheers

Just to take a quick victory lap to celebrate how beautiful scope clocks
can be!

It may take some time to track it down but I'd happily swap it
for a 4.1 if that simplifies things for you.

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

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.
