A full bridge rectifier with some enhancements

A full bridge rectifier with some enhancements

So I was working on this Full Bridge Rectifier for my high school physics project and saw those transistor-zener diodes working as switch and that capacitance there.

I wanna know how do they enhance the circuit and what are their functions - why did we use them in the first place..

They don't make products like this anymore. Guts of an antenna tuner. [X-post]

I'm too poor to buy Crocodile clips for my projects so I soldered my own from scrap.

I'm too poor to buy Crocodile clips for my projects so I soldered my own from scrap.

This is my first soldering iron I bought it for 15€ , solder wire is from grandpa , and the rest is from electronic scrap bin in my school. Not the best project (a 12 year old could do it [I am 18] )but for the first time soldering I don't consider it to be the worst.

Latching relay question

Sun, 01/07/2024 - 16:05

Hi all, I'm new here. I'd appreciate your help with the following.

I have a latching relay module (the Adafruit one if it matters - 3V). It's meant to be used with their Feather MCU but it can also be used standalone (which is what I'm doing).

That relay has two separate trigger inputs for SET and RESET. I have a timer board with a single OUT wire that can automatically trigger a relay, an LED etc. after a set amount of time.

My question is, is it possible to trigger the relay on & off somehow (without an MCU) by having that single trigger voltage (e.g. 1 wire) alternate between the SET and RESET separate pins of the relay?

So effectively, pulse -> SET, pulse -> RESET, pulse -> SET, pulse -> RESET etc.

I hope I've explained this property. Any questions, let me know. Thank you.

Makita Radio DMR102

Can somebody help me with this part? What is it called? Is it a transistor? On the right contact 12V arrive at it, but all the other ones are 0V. It's hard to read but I think it says YL4686 SA7BRLXD. Can't find anything by googling it.
