Lithium-ion batteries are flammable and the price of the raw material is increasing. Scientists and engineers have been trying to find out a safe yet efficient alternative to the Lithium-ion technology. The researchers of Empa and ETH Zürich have discovered promising approaches as to how we might produce powerful batteries out of waste graphite and […]

Features 3V and GND connections can be made from either side and allow you to power a second board such as the MonkMakes Relay Board or MonkMakes Speaker. LED ‘power on’ indicator Reverse polarity protection All three sensors are analog and can be connected to pins P0, P1 and P2 using alligator clips. Getting Started Connecting […]

During the academic year of 2016-2017 at McMaster University, in conjunction with Dr. DeBruin, Christina Riczu, Thomas Phan and Emilie Corcoran, we developed a compact, battery powered, 12-lead electro-cardiogram. The project won 1st place in the biomedical category at the ECE Capstone Poster Day. The final report we handed in for the course is attached […]

This is the first post of a 3-part series about reading out an SMA solar inverter over Bluetooth and displaying some readings every few seconds. Long-time readers may remember the Solar at last weblog post from several years ago and the SMA Relay, based on a JeeNode v6. The Bluetooth readout code was derived from […]

Hi all! I’m very busy last months working on new boards and projects, sorry for the delay! Some months ago I review the DSETA board due the obsolescence of the microcontroller. I use this board in some projects succesfully. But when I try to manufacture a batch of this boards, I found that the microcontroller […]

Introduction Previously I made a simple frequency-modulated continuous-wave (FMCW) radar that was able to detect distance of a human sized object to 100 m. It worked, but as it was made with minimal budget and there was a lot of room for improvement. FMCW radar working principle If you have read my previous articles you […]

Odroid is a great development mini PC board to make different IoT or other tech projects on. Needless to describe all the advantages of this marvelous device, as any reader of this post is likely to be really into this growing community. But if you are new to these boards, there are a bunch of […]
