DIY Analog resource monitor for your PC

Sasa Karanovic posted detailed instructions of how to build a physical dashboard for your PC, that is available on GitHub: The overall architecture is very simple; There is a python script that is running on a PC and collects CPU, memory, network and GPU usage. Then, it sends that information over serial COM port to […]

JesFs – Jo’s Embedded Serial File system

suchende tipped us to the small File system for NOR flash: The main problem for “very small devices” – until now – was the “File System”: everybody knows “FAT”, “NTFS”, … but have you ever thought of a file system on a small chip? Or even inside of a CPU? No problem, with the right […]

Aweigh: the open-source alternative to GPS

A team of student designers and engineers from the RCA and Imperial College have developed a substitute for GPS that does not rely on satellites, called Aweigh: Aweigh is an open navigation system that does not rely on satellites: it is inspired by the mapping of celestial bodies and the polarized vision of insects. Ancient seafarers and […]

LPCNet – Open Source Neural Net speech synthesis

Jean-Marc Valin has been working on Neural Network (NN) based speech synthesis in his project called LPCNet: This new demo presents LPCNet, an architecture that combines signal processing and deep learning to improve the efficiency of neural speech synthesis. Neural speech synthesis models like WaveNet have recently demonstrated impressive speech synthesis quality. Unfortunately, their computational […]

An open source VOR receiver for Airspy and RTL-SDR

A simple VOR receiver for Airspy and RTL-SDR called Vortrack by Thierry Leconte, that is available on GitHub: In the past we’ve seen several other posts about RTL-SDRs being used to decode VOR signals, but Thierry’s implementation appears to be the easiest way to get a bearing straight away. You’ll get the most use out of […]

How to build your Energy Load manager

A detailed instructions of how to build an Energy Load manager from Open Electronics: When the instantaneous power consumption exceeds the set values, it selectively disconnects the users, in order to prevent the electric meter to cut the power to disconnect. The management of the electricity users at home, intended as the possibility to define […]

Build a Multisensor Shield for ESP8266

Rui Santos has a great write-up on building a Multisensor Shield for ESP8266, that is available on GitHub: In this project you’ll discover how to design and create a Multisensor Shield for the ESP8266 Wemos D1 Mini board. The shield has temperature sensor (DS18B20), a PIR motion sensor, an LDR, and a terminal to connect […]

Open source RISC – Eclipse with RISC-V on the SiFive HiFive1 board

Erich Styger writes: Open Source software has been around for decades. But open source on hardware especially microcontroller is not much a reality these days. But there is something which might change this: RISC-V is a free and open RISC instruction set architecture and for me it has the potential to replace some of the […]
