The MonkMakes Sensor Board for micro:bit allows you to sense sound level, temperature and light level. 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 […]

Engineers and scientists from the UCLA Henry Samueli School of Engineering and Applied Science and SRI International, California, have created a thin flexible device that could keep smartphones and laptop computers cool and prevent overheating. The component is based on the electrocaloric effect – a phenomenon where the temperature of material changes when an electric field is applied to it. The research […]

uring 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 […]

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 Stuart Pittaway’s Nanode SMA PV Monitor code. This project is for a friend who’s birthday is coming up shortly, and who has the same SMA 5000TL inverter as I do – although it can […]

In next 10 years, the automotive industry will bring more change than we have seen in the last 50, due to technological advancement. One of the largest changes will be the move to autonomous vehicles, usually known as the self-driving car. Scientists from many universities are striving to implement vision processing with the artificial neural network to […]

Previously, I made a Pickit 3 clone – (See previous Blog Post). It works well, but I have often wondered just how little of its circuitry was needed to program and debug the boards I make. For instance – I primarily use the newer 3.3V PIC32 processors, so I really don’t need the ability to […]

SWEETENING THE DEAL With a few days left in our campaign, we will sweeten the MaxProLogic deal. We will now offer our newly developed BLE Board. This board includes the Texas Instruments CC2640 chip along with a 2.4GHz antenna and matching network. This board plugs directly into MaxProLogic. It communicates with the FPGA over a […]

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 FMCW radar block diagram If you have read my […]
