“Sensors are the best thing to get started with DIY electronics, you can get a wide variety of sensors, each suitable for one or more tasks. The Arduino is compatible with a variety of sensors and I’m going to …

“Sensors make working with any project fun and simple to do, there exist thousands of sensors and we get the choice to choose the right sensor for our projects or needs. But nothing is better than designing your own DIY …

“In the lab, one often needs a repetitive signal of a certain frequency, shape and amplitude. It may be to test an amplifier, check out a circuit, a component or an actuator. Powerful waveform generators are available commercially, but it …

“Why would I want a tiny oscillscope? I’ve got a room full of electronic Stuff including four oscillscopes. But it’s a fuss using them. It would be nice to have something that fits in my pocket, that sits …

“A few weeks ago we had the first version of this project, the portable soldering iron V1.0 and that had a few problems. The main problem was the soldering tip that I’ve used. It was very low quality …

“Low-cost, homemade AT switches that, unlike Jelly Bean buttons, work by many forms rather than by contact or pressure This project presents two open-source, low-cost, homemade AT switches that don’t work by physical contact or pressure like Jelly Bean …

“In this post we will see how to measure the current frequency and power with a non-invasive current sensor SCT-13-50, a dual amplifier LM358. The most interesting thing about this project is that we can measure the current without …

“I’ve always wanted a transistor curve tracer. It’s the best way of understanding what a device does.Having built and used this one, I finally understand the difference between the various flavours of FET. It’s useful for …

“This is a very intresting project and utlize very less efforts lts make a very simple RPM meter (Round Per Seceond In my case).”

“If your project calls for light sensitivity, it’s hard to beat light dependent resistors (LDRs), also known as photoresistors. They’re available for a few cents each, and their resistance varies based on how much light they receive. In …
