DIY IKEA Wireless Qi Charging

DIY IKEA Wireless Qi Charging

The Achilles Heel of the Mikroelektronika Hexiwear is its charging: the charging and USB connector are only designed for a limited number of plug-unplug cycles, and it does not have a wireless charging capability like the Apple iWatch. Until now! I have built a DIY wireless charging system for the Hexiwear ? : Wireless Qi […]

A battery small enough to be injected, energetic enough to track salmon

RICHLAND, Wash. – Scientists have created a microbattery that packs twice the energy compared to current microbatteries used to monitor the movements of salmon through rivers in the Pacific Northwest and around the world. The battery, a cylinder just slightly larger than a long grain of rice, is certainly not the world’s smallest battery, as

EAGLE BOM generation script

EAGLE BOM generation script

BOM-Gen BOM-Gen is EGALE ULP script to generate complete BOM (bill of materials) document for EAGLE PCB projects. This script generate BOM document as formatted HTML document. Usage Copy bom.ulp file to EAGLE ULP directory. Normally, in Windows operating systems this directory is located at “C:\Program Files\EAGLE-X.X.X\ulp”. Also note that this is an optional step

Mini 7 Segment Clock V3

Mini 7-Segment Clock V3

While I waited for the Mini 7-Segment Clock v3 PCBs to arrive, I got to work on designing an enclosure. First, I exported the PCB from EAGLE to SketchUp. I then assembled a complete 3D model with all the necessary components. With the 3D model complete, I could then design an enclosure to house the

Fuel-Gauge ICs Simplify Li-Ion Cell Charge Monitoring

For circuits relying on lithium-ion cells, determining the amount of charge remaining in a cell requires specialized techniques that can complicate the design of energy-harvesting applications. Engineers can implement these techniques with MCUs and ADCs normally used in these applications, but at the cost of increased complexity. Instead, engineers can easily add this functionality to
