Building A Robot Rover For Those Tough Indoor Missions
https://hackaday.com/2019/08/30/building-a-robot-rover-for-those-tough-indoor-missions/
Making an outdoor rover is easy stuff, with lots of folk having them doing their roving activities on beaches and alien worlds. Clearly the new frontier is indoor environments, a frontier which is helpfully being conquered by [Andreas Hoelldorfer]’s Mantis Rover.

Arduino on mBed
https://hackaday.com/2019/08/30/arduino-on-mbed/
Sometimes it seems like Arduino is everywhere. However, with a new glut of IoT processors, it must be quite a task to keep the Arduino core on all of them. Writing on the Arduino blog, [Martino Facchin], Arduino’s chief of firmware development, talks about the problem they faced supporting two …read more (https://hackaday.com/2019/08/30/arduino-on-mbed/)

Your Arduino SAMD21 ADC is Lying to You
https://hackaday.com/2019/08/30/your-arduino-samd21-adc-is-lying-to-you/
One of the great things about the Arduino environment is that it covers a wide variety of hardware with a common interface. Importantly, this isn’t just about language, but also about abstracting away the gory details of the underlying silicon. The problem is, of course, that someone has to decode …read more (https://hackaday.com/2019/08/30/your-arduino-samd21-adc-is-lying-to-you/)

When building robots, or indeed other complex mechanical systems, it’s often the case that more and more limit switches, light gates and sensors are amassed as the project evolves. Each addition brings more IO pin usage, cost, potentially new interfacing requirements and accompanying microcontrollers or ADCs.

ReMarkable Tablet Scores A MicroSD Slot

Steampunk Radio Looks The Business

Odd-Sized Military Headphone Connectors, Tamed!

Military headphones, at least the older ones, are like few other sound reproducers. They are an expression of function over form, with an emphasis on robustness over operator comfort. Electrically they most often have high-impedance drivers and annoyingly proprietary connectors for whichever obscure radio system they were a part of. …read more (https://hackaday.com/2019/08/31/odd-sized-military-headphone-connectors-tamed/)
