Smart Battery Charger

Many AA or AAA battery chargers charge batteries in pairs, but plenty of devices use 1 or 3 batteries, meaning that some of your batteries get overcharged and some get undercharged. NiCd and NiMH batteries also benefit from an occasional full discharge, which most normal battery chargers won't do. If you're anything like me you'll end up with a lot of rechargeable batteries, none of which end up being charg ...

Quick Arduino Hygrometer with OLED display

We have been having some condensation and mould issues in our apartment recently due to, I think, the humidity levels. Our property is relatively newly built and, as such, has very good insulation properties (double glazed windows etc.). The side effect of this is that there is very little ventilation and therefore humidity rises over a period of time and water then condensates on windows causing puddles on ...

Using HealthyPi with a PC for ECG, Respiration & SpO2

We initially made HealthyPi as HAT add-on board for Raspberry Pi. Now you can run the application on any desktop PC with a USB port. Project We introduced the HealthyPi as a HAT add-on for the Raspberry Pi, turning it into a full-featured, medical-grade open patient monitor. However, we realized later that people also wanted to use the board standalone with a Windows/Linux/Mac PC. We already had an on-board ...

Control an Arduino Zero using Node.js

I had to delve deep into the code, but I finally got nodebots working on an Arduino Zero Story I recently received an Arduino Zero, arduino.cc’s latest offering. I’d been experimenting with nodebots, so I decided my first Arduino Zero project would be a nodebot. Anna Gerber has an excellent tutorial for doing nodebots using Arduino at http://node-ardx.org/ Not only is it well written and suitable for beginn ...

Hack-proof RFID chips claimed by MIT

MIT researchers have developed a new type of radio frequency identification (RFID) chip that is extremely difficult to hack. If such chips were widely adopted, it could mean that an identity thief couldn’t steal your credit card number or key card information by sitting next to you at a café, and high-tech burglars couldn’t swipe expensive goods from a warehouse and replace them with dummy tags. Texas Instr ...
