“If you’ve played around with electronic circuits, you probably know the 555 timer integrated circuit,1 said to be the world’s best-selling integrated circuit with billions sold. Designed by analog IC wizard Hans Camenzind2, the 555 has been …
“I had a really difficult time understanding exactly what 555 timer circuits do and how they work. Most explanations online refer to their functionality when paired with RC series, but not exactly what logical interactions between the different input pins …
“A Working Replica of the classic 555 timer made using discrete components A fully functional replica of the classic 555 timer made using discrete through hole components which include only basic jellybean components like (to - 92) BJTs , 1/4Watt resistors …
“The project is a sample project about how matrix monitors works. The scroll speed can be set by a potentiometer. A Bluetooth module added to the project. So, you can send texts to your board with a smart phone. A …
“Hey everyone what’s up, SO here’s something really cool, a small Christmas tree-themed PCB powered by 555 timer ic and a CD4017 Decade counter. The idea here was to make a simple Blinky Board that drives 10 LEDs …
“A relatively sensitive IB (Induction balance) Metal Detector which is very easy to make, and contains a few standard electronic components In the previous period, I presented several types of metal detectors that were based on microcontrollers and Android smartphone …
“After various experiments and failed attempts to design a 7400-based computer, I came to a quite minimalistic 8-bit approach which is nevertheless pretty versatile and can utilize a surprisingly large amount of memory resources. The CPU core itself executes its …
“Ok - so this is going to be my last dub siren build (maybe…). This new one is an extension on the others that I have built and is definitely the best and easiest version I have designed. So what is …
“This spooky electronic ghost is a 555 LED flasher circuit encapsulated in silicone rubber.”
“These days good quality oscilloscope is not an expensive instrument and, we can see it in most workbenches. With the advancement of oscilloscopes, simple testing tools such as logic probes are not as popular these days. However, if the oscilloscope …
