Jesus Echavarria has tipped us with his latest project. A car battery monitor in a Relay form Factor. Unfortunately only hardware details are given and no details on software. He writes: Hi all! I’m really busy this year so I can’t post all the projects where I’m involved....

But what is uStepper? In short, uStepper is a product, improving performance of a motor type called “stepper motors”. Stepper motors are used in a wide range of applications where you have to move something, a certain distance, precisely! For example, they are used in your inkjet...

A team led by the Technical University of Munich (TUM) physicists Alexander Holleitner and Reinhard Kienberger has found success for the first time in generating ultrashort electric pulses on a chip. They made this possible by using asymmetric metal antennas only a few nanometers in...

You want to maximize the power output of your solar panel? Then you need a maximum power point tracking charge controller! Source files here. Features: Programmable with Arduino IDE Input voltage: 15 - 22V Output voltage: 1 - 14.4V Simple MPPT (Maximum Power Point...

Designers working on line-powered systems are in luck… Designers working on line-powered systems are in luck; whilst wasting power is always bad, a few mA of waste don’t really matter. When working on battery powered systems, every bit of energy helps – an efficient switching...

One thing technology has taught us in the last few years, is the so-called powerful devices of yesterday, will not match the devices of today or tomorrow and this is something that is transcending in the hardware industry. Maker's board have seen a drastic improvement ever since the...

The ARM Cortex family of 32-bit RISC-based processors has emerged as the leading processor core in embedded designs due to its efficient architecture, robust and scalable instruction set, and extensive base of development tools and software. Cortex-M MCUs has been one of the most used...

Mare published a new build: Particle sensors could be cheap and easy to use. Disadvantage of lowest cost PM sensors is lack of “calibration”. The best method to measure particle content dispensed in the air is to collect the air sample and analyse it off-line in the laboratory with...
