isoUSBRS422, an open source isolated USB-RS422/RS485 converter board

Alper Yazar has posted an update on his open source isoUSBRS422 project we covered previously: As I said, basically it is an USB ↔ RS-422/RS-485 converter board. It can be used to communicate devices with RS-422/RS-485 interface by using a USB port of PC. Also, ground of USB port is isolated from ground of RS-422/RS-485 […]

Open Inverter, an open source micro-solar inverter

Ken Boak has been working on an open source micro-solar inverter project: We wanted to make a design that uses readily obtainable N-type FETS and an Arduino (more strictly a ATmega328P-PU on a breadboard) to generate the PWM signals and provide simple circuit protection, and load sensing. With the PWM signals generated in firmware it can easily […]

ChainringGen – making a chainring with open source software

Rich Olson writes: ChainringGen is an OpenSCAD script I wrote that can generate a bike chainring with any specifications you like. You can download ChainringGen here.  You can control parameters like bolt-circle-diameter (BCD), number of bolt holes, number of teeth and other stuff. I primarily created ChainringGen because I thought designing / milling my own […]

Proof of concept: Open source ARM SWD debug and general purpose board

Erich of MCUonEclipse writes: The Freescale FRDM boards are using a Kinetis K20 based circuit (see “OpenSDA on the Freedom KL25Z Board“): However, that firmware is not open: the K20 is secured and protected, so the firmware cannot be changed. Newer Freescale FRDM boards like FRDM-K22F2 and FRDM-K64F do have an open source bootloader and debug […]
