A while ago Farnell sent email to me and offered one (inexpensive) product as a sample in exchange for mentioning it at this blog. I browsed for a while for an interesting part and settled with Microchip MRF24WB0MA/RM WiFi module (Order code 1823142). This module is quite inexpensive and is used in products like WiShield and thus has good Arduino

Summary The solar energy collection is not that easy compared to the different types of power generation system because it has the lowest capacity factor. It has 5 out of 24 hours in a day that it can generate electricity from its solar collection. The only solution to this is by optimizing the 5 hours

An implantable, microchip-based device may soon replace the injections and pills now needed to treat chronic diseases: Earlier this month, MIT spinout Microchips Biotech partnered with a pharmaceutical giant to commercialize its wirelessly controlled, implantable, microchip-based devices that store and release drugs inside the body over many years. Invented by Microchips Biotech co-founders Michael Cima,

I designed this circuit for the same reason that i designed the SMPS Boost regulator with the MCP1640 – To gain experience in SMPS technology. This time i use the high power LM2595 buck regulator. The circuit accepts any AC voltage from 8 to 45 Volts. This wide input voltage range is a remarkable feature!

The BareDuino Nano is the world’s smallest Arduino compatible board. It was designed by a very young maker, Niek Blankers, aged 15, from the Netherlands. Niek has been interested in electronics since he was less than 8 years old. A couple of years ago when he was given the first Arduino board, he fell in

This article shows you how to build a very simple FM transmitter from thirteen components, a Printed Circuit Board (PCB) and a 9v battery. This project was designed to be mounted on a PCB, however you don’t have to. You could construct the project on Vero board (strip board) or any other 0.1” pitch style
