It said high-voltage reference on the tin. I expected high-voltage, just not 100kV.

We just released a new video on theory and experimentation with high speed high linearity analog optoisolator circuits, DC to 1MHz.

I feel it turned out pretty well, give it a watch!

Boosts appreciated!

first board of the year! (designed and ordered last year)
this is a bipolar analog bias supply for bread-board and also solder-on use.
this is, i think the third iteration of this circuit and i got tired of layouting it over and over again so now it’s a module.
It‘s wide-vin with a boost, an inverting buck-boost and a TPS7A39 LDO to have clean supplies.

@LucasWerkmeister what is a qid? Or what do you mean by item ID?
Jonas 3j14Dec 21
@sad_electronics yes! I need this! Also good to look up common parts that are easy to source and have alternatives available

of course the LEDs are also animated

they work! I'm now running rust on my earrings.

and battery life is much better than expected (more than 4h, depending on the brightness of the LEDs).

@sad_electronics wait, the USB ports are blue so I would expect it to be USB 3. Is that not standardized?

Out of curiosity, what vendor ID is reported when plugging this into a computer? I have no idea, does the chip already come with a vendor ID? Or do companies (in this case Hema) use their own when manufacturing devices on a commercial scale?
