“A tiny 8x8 matrix clock that automatically rotates the display when the cube is rotated. Recently I stubbled across the Lexon Flip Travel Reversible LCD Alarm Clock. It got me wondering about a clock that always showed the time in …
“Complete the Arduino-based Drone Assembly with the Arduino-based Receiver and Flight Controller as well. This is the third and final part of our Arduino-based Drone Series. In the first part, we made a flight controller for our drone using the …
“The project presented here is a dual output linear power supply. This power supply provides low ripple low noise DC regulated output. It is a very useful tool to power Audio, Video, OPAMP-based circuits, and projects. The circuit provides …
“This project is a solution to power up most devices or projects requiring dual (+/-) adjustable power. The circuit consists of a stepdown transformer, bridge rectifier, DC filter capacitors, LM317 positive and LM337 negative adjustable voltage regulators, 2 x trimmer pot …
“Simple FM stereo receiver based on QN8035 for Raspberry Pi. The QN8035 is a stereo FM radio receiver launched by the Quintic Corporation. Compared to other popular digital FM tuners (RDA5807, TEA5767, etc.), this tuner does not seem to be …
“I have assembled many desktop computers over the years but it’s just not the same when you don’t use a soldering iron! I wanted to build a computer from scratch for a long long time because I find …
“I wanted to build a TinyML model that could detect when a boat is nearby by listening for it on a hydrophone. Edge Impulse makes it easy to build ML Models that can run on an Arduino board and detect …
“A small hand-held tachometer that uses a laser to show how fast an object is rotating in revolutions per minute (rpm). This Laser Tachometer is a rebuild of Elite Worm’s Build a Laser Tachometer. Both the hardware and software …
“The Valden Heat Pump controller is an open source platform to precisely control heat pumps. This controller can be used for the automation of newly built Heat Pumps (HPs), as a repair controller for old systems or as control system …
“The project described here is a high-efficiency dual BTL class-D audio amplifier with single supply operations. The project was built using TDA7491LP13TR from ST. The low profile PCB design can fit in a small area, operating power supply 9-12V DC …
