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.

True, but the schematic is SCTV rev. C which is for Teensy 3.6. Does anyone
have the schematic for using Teensy 4.1? Just designed a clock based on

Thanks for your reply. That's impressive.
As a 3.3V regulator I'm using a simple MCP1700, but that takes about 6.5uA,
that's "too much" vs 1.6uA declared in a the datasheet, I tried a few
parts, maybe not a genuine batch...
Then 2.4uA is taken by the power supply DC/DC converter. This can be

Regardless of which power supply I use, e

Aidan, the kickstarter link is not working any longer, at least for me. It

Do you have any tests on efficiency at 3.7V li-on battery input and 170V
1mA / 2mA and 4mA?
Would you have any suggestions on how this is even possible: 7 years ago,

Hey guys, I did manage to find some B-5870 on the internet after a short

WoW! That was quick!
What is a sensible price to pay for any of these tubes these days? B5853,
B5870, B5750 and the likes. Just looking for an idea of the range of
prices, although I understand large quantities can push the price down, I'm
just looking to have a sense of what is fair to pay.
