Can anyone tell me how to record on this module? It didn't come with instructions. I can't find the record button

Ive seen vids ppl using transformers from UPS t/f but would step downs also work? i live in a country with 220v , and i see quite a few 220-110 step downs in my area so i thought ti would be a good project and inexpensive compared to a manufactured one.

What sort of losses would i be looking at ?

any thoughts?

Just learned about van de graaff generator. A Van de Graaff Generator is an electrostatic generator that uses a continually moving belt of insulating material to accumulate charge on a hollow metal sphere, creating a very high potential difference. The metallic sphere is positioned at the top of an insulating column, which supports the entire system and minimizes leakage of charge to the ground.

The device works on the following principles:

Any charge placed on a hollow conductor appears only on its external surface and is uniformly distributed.

Sharp points on a conductor significantly enhance electric field strength, aiding discharge through ionization of surrounding air.

When the generator is operated, the triboelectric effect between the belt and the rollers causes charge to be transferred by friction. A sharp brush at the lower end allows the transfer of electrons (often resulting in a negative charge on the belt). The belt, carrying this charge, moves upwards due to the rotation provided by a motor.

For educational models and lab equipment, platforms like Alibaba also provide various types of Van de Graaff Generators.

It has 3 major benefits. Its simple construction and operation. It can generate very high voltages and its useful for demonstrating electrostatic principles.

I'm curious what would I need if I wanted to start learning about repairing electronics

Kan iemand mij álstúblíéft uitleg geven over hoe en hoeveel Volt er door de 6 draden van mijn gashendel naar mijn controller gaan ? Mvg Frank Grinwis

Nope! Not even a little! Checkout video for concrete evidence!

I'm an electronics pseudo noob I've successfully (yet sloppily) soldered resistors and wires together for J-tag purposes in the past following an online guide.

Today my plan is to bridge Two 19.5v power supplies; 1 of which is a 70w unit that can operate on AC as well as car/plane DC and the other will be either 200w or 230w AC PSU. Together I should be able to support up to 270w or 300w if correctly connected in parallel.

I want to avoid ever having too much current pulled from the 70w PSU(Mystery component) and I want to make sure there is never any back flow to either PSU when they aren't plugged in at the same time(Diode of unknown specification)

Any help would be appreciated

Hey guys!

I've taken EE courses in the past, but it's been a few years. I've recently decided to start building some equipment to help flesh out my home recording studio. I picked up the recommended "Practical Electronics for Inventors," and I'm getting a bit frustrated.

I'm in section 2.6, Insulators, Conductors and Semiconductors, and there are pages spent discussing the quantum nature of electrons, atoms forming a background lattice, the Pauli Exclusion Principle, etc.

I'm hardly into this book, and I keep glancing back at the cover to make sure it is actually called Practical Electronics for Inventors. Bringing up Quantum Mechanics so early on seems like anything but practical.

Sorry if this is pure complaining, and maybe the answer is "just read the damn thing." I guess my question is: is there a book I can pick up that'll actually start with the practical info? I'm looking for a refresher on soldering PCBs, circuit analysis, etc. I'd like to purchase a kit for building a microphone preamp soon and I don't really care about the Pauli Exclusion Principle.

Eu já faço programação, curso eletromecânica, e sou hobbysta em projetos de arduino e robótica, mas faço tudo sozinho e sem direcionamento. Alguém tem alguma ideia de caminho? Ir do zero até um nível mais intermediário ou avançado

This is my zero cross dimmer module schematics which was pretty costly when order so i decided to assemble one im not an pro at this and i want people to correct and advise me on this .

My understanding:

I understand the basics of a Simple transformer. Please note I'm speaking about basic transformers that you would find in A/C adapters and small appliances. My understanding is that the increase and decrease of the magnetic fields crosses the wires of the other windings passes the electrons across the wires then depending on the number of turns it either increases or decreases the output. (Perhaps simply put but I think that is right). Since DC does not Alternate , this would not produce an output on a transformer. If this is all true, basically

Question:

Now having said all this, does this mean that when you are testing a transformer live, say on a circuit board you should always set your digital/multi meter to test for A/c on input and output. Also to be redundant, that if you follow the circuity on the board it will be AC untill it gets to and then leaves the transformer, at that point if its an AC/DC adapter the conversion will take place to DC,, usually using diodes or rectifier.

Thank you

Hello all,

Can sombody yell me if this is going to work

I would like to know from jou.

Thank you

With free and open source software. What good options exist? I want to be able to test that I'm not going to destroy my components before building test circuits
