LoRa security camera detects and transmits trespasser data

Security cameras are a great way to deter theft and vandalism, but what if the camera is out of WiFi range, or otherwise would need long cables to transmit pictures? As explained here, Tegwyn Twmffat has an interesting solution–taking advantage of neural network processing to…

CircuitPython 4.1.0 Beta 0 Released!

From the GitHub release page: 4.1.0’s biggest feature is speed! General execution of Python should be 2-5x faster and display refreshing will be faster as well. This is the first beta version… Source : CircuitPython 4.1.0 Beta 0 Released!

iArduino: a C Interpreter for Arduino #C #Programming #Arduino

N. Mitsunaga posts about iArduino: a C Interpreter for Arduino. Rather than using compiled C/C++ as in the official Arduino IDE, iArduino is interpreted at runtime like Python/CircuitPython but in … Source : iArduino: a C Interpreter for Arduino #C #Programming #Arduino

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
