MakerTronika Labs has launched their Feather compatible board with LoRa connectivity called Penguino Feather 4260. The Penguino Feather is a SAMR34 based LoRa/LoRaWAN™ dev-board with all the necessary components for fast prototyping. It's a successor of my previous Penguino...

Gerber Labs, an Orange County-based engineering startup, is rolling out a platform that makes custom printed circuit boards (PCB’s) accessible to electrical engineering students, hobbyists and small businesses. PCB’s traditionally have only been accessible for large businesses and...

In many applications, all you need is an MCU with reasonably low processing capabilities just to interface with sensors and send some data through a transceiver or even provide output to a display or actuate on something. For these simple tasks, an 8-bit microcontroller is usually just...

This motorized slide potentiometer is used in lighting and Audio/Video equipment or other similar application. It is a simple solution to control a motorized slide potentiometer using two tactile switches or a microcontroller interface. The project includes bidirectional motor driver...

This is a new project, a single supply instrumentation amplifier with onboard bridge configuration, and a 2.5V precision reference voltage chip. The project can be configured for applications such as thermocouple amplifier, bridge amplifier, ECG amplifier, pressure sensors, medical...

Precursor is a compact device with a physical keyboard, a built-in display, and an internal battery. It is an open hardware development platform for secure, mobile computation and communication, this device offers a system that users can have nearly complete control over, also with an...

This is a tiny module that allows users to charge small Li-ion batteries, CR2032 or equivalent, from a low power source such as a small photovoltaic cell. The project consists of the LTC3105 step-up DC-DC converter chip which features Maximum Power Point Control (MPPC) and 250mV...
