Basic questions about simple circuits, single parts and components. Earn respect by helping new members learn electronics. Do your own research first! Ask specific questions, show that you did some work before asking and the help will be plentiful.

General electrical circuits, design, teardowns, audio, induction heating etc, if it is not directly high voltage related it belongs here

Layout, good practises, production, and design

Everything related to computers, other programmable devices and their human-machine-interfaces

Neon sign transformer (NST), Microwave Oven transformers (MOT), polepig transformers, Potential transformers, Oil Burner Ignition transformers (OBIT), Ignition transformers, old x-ray transformers etc

High voltage inverters, new x-ray transformers, flyback transformers from TVs and monitors etc

Marx, cockcroft-walton etc

Vimhurst, Van de Graff

DC charging, rotating spark gap, static spark gap, powered by NST, MOT, polepig etc

SSTC, Slayer exciter, Royer driven, single transistor

DRSSTC, QCW

Vacuum tubes, radio valves, thermionic valves

Discussion on construction, design and safety related to capacitors used for pulse energy discharges and their accessories like spark gaps, trigger mechanism, fail safe circuits and measurements. Can crushers and coin shrinkers etc also belong here

Discussion of coil design for induction/ring launchers, rail/coil design for guns, spark gaps, triggering mechanism, use of solid state switches etc

Radio Amateurs, infrared, microwaves, wireless communication, blue-tooth, WiFi etc

Everything related to light, be it visible or not

Sources, sample collections, polution, places and sites

If it has anything to do with x-rays, this is the place

Back ground radiation stations, dosimeters, cosmic ray counters etc

Apps like time lapse, slow motion, filters

Regular consumer cameras, custom firmware etc

Discussion of best settings for shutter, aperture, ISO etc

Discussion only for dedicated high speed cameras

The town square where you can chat about any topic allowed by the site rules

Discussion and posting of news from other fields of science than those that have special forums on this site already

Show off your lab, hackspace, garage, shed or work shop

Do you have a website, youtube or social media account where you show electronics, make other users aware of it here

Contents and events can be announced here or you can share a interesting one that you found

The only place where it is allowed to ask other users for help/sharing/money to your crowdfunding project, advertise for it here, nowhere else

It is only allowed to post on the selling board if you have at least 25 post count. Commercial advertising is allowed for small start-up companies, 1 man companies or other similar companies with a niche production in high voltage parts
