On Kickstarter, the lead engineer of the $9 C.H.I.P. computer and team are introducing new single board computers under the name Popcorn: We are building the next-generation of single board compute… Source : The C.H.I.P. computer is back as Popcorn @PopcornComputer

An Open Source ESC For Brushless Motors

For something basic like a brushed DC motor, speed control can be quite simple, and powering up the motor is a simple matter of just applying voltage. Brushless motors are much more demanding in th… Source : An Open Source ESC For Brushless Motors

Battle Tested Current Limiter for Cheap DC Motor Controllers

Running a brushed motor in muddy or dusty environments takes a toll on controllers, with both heavy back EMF and high stall currents. This explains one of the challenge in Europe’s Hacky Race… Source : Battle Tested Current Limiter for Cheap DC Motor Controllers

Simple, Self-Contained LoRa Repeater In About an Hour

[Dave Akerman]’s interest in high-altitude projects means he is no stranger to long-range wireless communications, for which LoRa is amazingly useful. LoRa is a method of transmitting at rela… Source : Simple, Self-Contained LoRa Repeater In About an Hour

A Breadboard Power Supply That’s More Universal Than Most

A favorite project of ours is the humble breadboard power supply. Yes, you can still prototype on breadboards, no, you don’t need an entire bench power supply to prototype on one, and every b… Source : A Breadboard Power Supply That’s More Universal Than Most

Rudimentary ultrasound machine made with Arduino Due

Ultrasound images are an important tool for medical diagnosis, and while units used by doctors can be very expensive, getting a basic image doesn’t have to be. Inspired by this attempt at a $500 ultrasound machine seen here, maker “stoppi71” decided to create his own…
