“Prototyping is a dangerous job. Not for a person if you keep the voltage down but for the components. On breadboard misplaced chips, loose connection and other errors can blow the components. To save them a fuse is a good …
“Simple DIY switch for 12V lamps. Activate with a clap, turn off with another clap.”
“The Step-Up DC-DC Converter project provides 28V, 175mA output with input of 12V DC. The MC34063A IC is heart of the project from On semiconductor. The MC33063A is a monolithic control circuit containing the primary functions required for DC …
“The board built around LM2575-ADJ from Texas instruments. A 1.0 A output current capability power supply that features an adjustable output voltage, This regulator board delivers 1.0 A into 1.2 V to 35 V output. The …
“The DRV101 is a low-side power switch employing a pulse-width modulated (PWM) output. Its rugged design is optimized for driving electromechanical devices such as valves, solenoids, relays, actuators, and positioners. The DRV101 module is also ideal for driving thermal devices …
“Bagpipe chanter playing robot. A chanter is a low cost device allowing you to learn to play the bagpipes. It resembles the important part of bagpipes, i.e. the part that plays the main tune with a reed and finger …
Project Designing a simple and cheap temperature logger. Part 3: Open collector, FATs and de-debugging
“I had at last some time to work on the project. The prototype PCB is (at least, electrically) functional. I started with making the TMP102 temperature sensor work. Nothing to say in particular, it’s just an other I2C-small-package-sensor …
“In this instructable I will show you how I made an electronic “decision maker” with the 4046 - phase-locked loop. What does that mean you ask? Well it’s basically a coin flipper. You press the button to start the oscillation …
“After many hours of work I’m very happy to finally publish all the sources for the ESP8266 PlaneSpotter project. It is not yet really in a V1.0.0 state but I’m sure with the help of the …
“I have a drawer of random electronics parts and failed dreams. Amongst this pile is a handful ESP8266 chips. These devices are intended to be used as low-cost WiFi modules which are operated by other microprocessors, and by default you …
