Two reasons I would hesitate here: PROGMEM is flash, and therefore can have some performance complications in getting things into and out of it. P...

10bit to 16bit doesn't matter in terms of data storage unless you're being very fancy. In both cases it's 2 bytes. 2000 bytes / 2 bytes per sample i...

This is very true, and I was trying to figure out where it came from.... then I saw it in my code snippet. Oops! That is definitely a mistake. Avoid...

Memory is pretty tightly constrained on the arduino platforms. AFAIK you're limited to 2k of SRAM for all variables. /p> I would also be somewhat su...

This is actually a fun thing to experiment with. Try the following code with an arduino and an oscilloscope: bool x = false; void loop() { x ...

I share your concerns about plastic... I was particularly concerned about the plastic that holds the solderless breadboard contact springs in place, a...

I'm not exactly sure what the usecase is, but this doesn't sound too different from limit switches attached to an axis on a 3d printer. The trigger in...

There are basically two things going on with paired connections. 1) The ATX specification requires sense lines on some of the supply lines. If you s...

I'm going to disagree with the conclusion we've come to here. But first an explanation of what pihole does. The internet as we know it runs on an ...

I'm actually a little bit more concerned about running the FTDI programmer in 5V mode for programming a chip that runs on 3.3V logic. But I haven't lo...

Hmm... I hadn't looked at that video in detail. I agree there is a contradiction here between the two videos. Your onboard AM1117 _is_ going to be f...

The ESP32 chip itself runs on 3.3V. For convenience, the board has an AM1117 regulator that will bring a 5V power line down to 3.3V. The 3.3V pin look...

I'm not sure if you've looked around... but capacitors in this range are kindof monsters. The largest you usually find are measured in tens of MILLIfa...

I did quite a few things based entirely on the following: A variable voltage supply, modeled after our host's design here: One major modificatio...

Sure! Conceptually, just reversing the leads on any DC power supply is providing a "negative voltage", but not something that's very useful since we'v...
