After stumbling around with #arduino and #esp32#embedded stuff for some years, I now have the time and energy to learn #C++ properly. Time to actually understand what I've been doing all these years. Understanding types and the standard library is appealing.
I've always avoided C and its children but for embedded stuff it's kind of unavoidable. I'm looking at YOU ESPHome Display Lambdas: the power of C++ gimped by the annoyance of YAML!
Does anyone have course recommendations for learning C++ pretty much from scratch? It could be targeting embedded dev but a generalist course would be fine too I think.
This is what I have: When you scroll the knob it shows the number on the display (with brightness set dim) and then when you press the knob/button
it sends that value via MIDI output and then flashes 4 time and shows the number at full brightness.
The flashing lets you know you've set the value and sent it.
And "dim" means you are selecting a value and "bright" means you have chosen the value to send.
Does anyone know where I can find cheap #ADB to USB adapters, or if it is easy to build one using an #Arduino / #Teensy ? I have an #Apple Extended #Keyboard II I would like to put to good use.
I found only 2 relevant listings on AliExpress, and for some reason both are priced around US$ 400 each! 😱 #Mac
Did someone tried simply connect a water pump to #Arduino? I did. Arduino just controlling a relay (or MOSFET). Engine and Arduino has different power source.
Despite of it water pump producing so much #EMP what leads to Arduino random restarts.
As generator of random numbers it works perfectly. But I've expected something else :(
Some advices? Water pump is plastic and I can't solder any capacitors on it.
I'm once again asking for some #fedihelp to solve a #WoodWorking philosophical dilemma.
When cutting wood on a bandsaw with a fence, which side of the board is better to keep against the fence, the narrower or the wider (assuming both sides can pass through the saw throat)?
I usually keep the wider against the fence, but I don't know if it's the best practice (I push the piece against the fence not farther than the blade, or it will pinch it, of course).
The arcade version of Arkanoid is hard as it is, but with a joystick/gamepad is next to impossible to play. 🕹️ 💢
Originally it used a rotary controller (spinner). On an emulator, you can play it with a mouse... but that just doesn't feel right. And, with my setup, not very practical. 🖱️ 🤷♂️
So, I decided to build my own spinner controller. I think it turned out quite nice...
