I bought my first Arduino UNO R3 kit two weeks ago (the Elegoo Super Starter kit) and am stepping through its tutorials. In parallel I'm trying to learn the basics of its C++ based programming language, but that's proving a struggle. I'm impatient to use Arduino on my own projects so I will take a 'copy/paste/edit' approach. It then becomes a matter of finding sketches that cover a particular ...

Hi all, A member of our radioclub is starting to have problems with his eyesight, so he is looking for a multimeter that can talk. I've found one on the internet, but that product is only sold in the US. Anybody any idea for a not to expensive talking multimeter that can be purchased here in Europe? thx! Kristoff

Hello, My Motorola phone supports "Turbo" charging, apparently charging my phone at 9-12V after establishing a secret handshake with the charger. https://www.motorola.com/us/products/turbopower Is there a chip that performs this authentication? I'd like to build a car charger for my phone without blowing it up, but I haven't seen any sample schematics. All I've seen is a reference t...

Hello, What are some examples of oscillators which don't require transistors or vacuum tubes? So far I found relay oscillators and the Pearson-Anson oscillator. Does the Pearson-Anson oscillator require a high-voltage neon lamp, or would it work on LEDs as well? https://en.wikipedia.org/wiki/Pearson%E2%80%93Anson_effect Relay oscillators look neat too but I don't imagine they would la...

Is it reasonable/possible to build an 8 amp 20 V transformerless power supply from a 120Vac line. I calculate about 180uf plus or minus depending on other components. Maybe 9- 20uf caps in parallel? I'd like to build it into a leaf blower. All plastic, absolutely no metal exposed. I think I've answered my question, I have 12, X rated caps in my junk box, but they are only...
