USB-C to 300V Troubleshooting
In my last post I described the challenges in using the LT3750 as a high voltage power supply. Namely, the power supply needs to be restarted after it reaches its target voltage, since it is a one-shot “charger”. An additional problem is that when inspecting the output voltage, it didn’t quite match the calculated output.…
Micropropagation of wild-type Vaccinium Vitis-idaea
A few years ago my friend introduced me to a tasty and edible berry while we were on a hike up mount Washington. I had no idea what it was, and much later I learned that they were lingonberries, which are related to a lot of other shrubby berry plants like blueberries. Recently I learned…
Adjustable High Voltage USB PD Power Supply
When I say high voltage, I don’t mean 20V, I mean around 300V, for high-voltage DC needs like electrophoresis or electrowetting. This is a gratuitous and impractical project, since you can buy an electrophoresis power supply for about $100. However, I wanted to do a more compilated design, and I “needed” a test PCB for…
