“Dark activated LED light is a simple project which operates a LED when the light falling on the LDR goes below a set point. The circuit is built using LM393 comparator, LDR as light sensor, preset (potentiometer) for sensitivity adjustment …
“This is a discrete Half-bridge driver based on IR2104 gate driver IC and low impedance high current N channel IRFP4368 MOSFETS. The IR2104 is a high voltage, high speed power MOSFET driver with independent high and low side referenced output …
“In this instructable I will show you how I made an LED flasher with Knight Rider effect. The circuit is relatively simple. For me the hardest part was etching the PCB.”
“Frequently I will install a control system to later find out —it doesn’t work or work properly. Have you been there? My aim with this project is to find those anomalies and “gotcha’s” before the first wire is …
“This project is also a Hackaday Prize 2015 entry, which isupdated here. This is still an active project, so the photos dont show the final unit, but should be more informative as you can see the different items I am …
“So, you’re an electronics hobbyist and want a 1GHz active probe, or a professional and tired of blowing your 2000$+ active probe in sketchy circuits when all you wanted to know are the whereabouts of some RF-signal? Then …
“My friend came to me with a simple request. To repair his electric wheelchair after it was damaged by lighning while on charge. The chair was fitted with a Shark controller, and on opening, there were severe flash-overs visible on …
“While writing the article on multiplexing the esps inputs I came up with the idea of PWMing all the outputs at once by interrupting the path to ground with an n-FET. Thats actually not a bad idea, and I …
“LIFETIMER counts down until I die. I think it’s set a little long — scratch that, way too long. Assuming 2.5 billion seconds in a human life you can then string it out to the correct number of digits …
“This project is intended to replicate some of the smart doorbells that are on the market. This version will detect when someone has touched the doorknob or doorbell and either tweet, text, or email a picture of the person at …
