MPPT Solar Charger Design based on PIC18F26J50
https://www.electronics-lab.com/mppt-solar-charger-design-based-pic18f26j50/
Lukas Fässler shares his Maximum Point Tracker Solar Charger Design based on PIC18F26J50: At the core of the design is a PIC18F26J50 in a 28 pin SOIC package. It’s capable of running at down to 2.15 volts and consumes extremely little power when running at lower clock speeds. And apart from that it features USB […]
CO2, temperature and humidity monitor
https://www.electronics-lab.com/co2-temperature-humidity-monitor/
An open source CO2 monitoring project from Roving Dynamics: The project described below uses a MH-Z16 or MH-Z19 CO2 sensor and a DHT-22 (or DHT-11 if less accuracy is required) to measure the Temperature and Humidity. It has a 4 line by 20 character LCD Display to show the current readings and status, a warning alarm […]
Ultrasonic Anemometer Project Progress
https://www.electronics-lab.com/ultrasonic-anemometer-project-progress/
Lukas Fässler discuss about his anemometer project progress and what tests he has performed so far. In the mean time I managed to do some rudimentary testing and now feel confident to take orders. These tests concern the hardware only. What I said last time about the state of the software still applies. But let […]

Intended for tasks such as monitoring IoT networks from a handheld device, Texas Instruments’ latest series of microcontrollers are single-chip Sub-1 GHz plus Bluetooth low energy ICs. By Graham Prophet @ www.edn-europe.com As part of TI’s pin-to-pin and software compatible SimpleLink ultra-low power platform, the SimpleLink dual-band CC1350 wireless MCU enables developers to move from […]
Infinite Noise True Random Number Generator
https://www.electronics-lab.com/infinite-noise-true-random-number-generator/
waywardgeek @ github.com shares his USB TRNG: The Infinite Noise TRNG is a USB key hardware true random number generator. It uses what I call a “Modular Entropy Multiplier” architecture (previously Infinite Noise Multiplier or FireBug). Besides being simple, low-cost, and fast, it is much easier to get right than other TRNGs. It naturally defends […]

The Tiny Lisp Computer is a self-contained computer programmed in Lisp. Some programming examples are included in the author’s website. This article describes a self-contained computer with its own display and keyboard, based on an ATmega328, that you can program in Lisp. You can use it to run programs that interface to components such as […]
OSHW Logo Generator
https://www.electronics-lab.com/oshw-logo-generator/
Here is a proposal for a new OSHW logo which uses release symbols to know exactly what the license covers. The KEYS used are: S = Schematic P = PCB F = Firmware and/or software M = Mechanical CAD files D = Design Documentation B = Bill Of Materials C = License used allows for […]
