In my previous post, I showed my design of a dual tracking ±30V linear power supply. My goal was to use the transformer (28V+28V, center tapped) from an old Deltron W127G open-frame power supply and build a lab supply that can be digitally adjusted in both constant voltage and constant current modes. I also wanted […]

TOREX Semiconductor Ltd. has developed the XC6190 series of push button Reboot Controllers, designed to provide a system reboot signal to the controller used in small wearable devices. The chip itself measures just 1.3 mm square (USPN-6 outline) and is available in four variants. The A variant only requires one external resistor to define the […]

If the design engineer’s choice of microcontroller was simple once, it certainly is not now. Massive improvements to the processor capabilities, availability of peripherals and power-saving functions of microcontrollers have created huge new opportunities for OEM designers to develop new products and to improve the performance and features of existing products. But the development in […]

Anne Mahaffey is an engineer with Analog Devices and was one of the beta testers for the Arduino Due. Anne’s been an ardent advocate for Arduino at Analog, and recently contacted us about a workshop she was planning with the Iron Yard, an accelerator in her hometown of Greenville, South Carolina. The workshop was to […]

I am twenty years old. I picked up my arduino for the first time this Christmas, and I’ve been keeping busy on my arduino applications so that I can bring you this instructable. I hope that it helps!!! The purpose of this project was to build a stepping stone from remote controlled flight to completely […]

Last March, Alexandra Deschamps-Sonsino registered a new limited company in London, and booked a booth at CES, the consumer electronics trade show, taking place 10 months later. She had no team, and only a dated prototype product that she had designed back in 2005. “I thought what’s the biggest kick in the ass that I […]

Scientists have come up with a way of creating sensors which could allow machines to smell more accurately than humans. Every odour has its own specific pattern which our noses are able to identify. Using a combination of proteins coupled to transistors, for the first time machines are able to differentiate smells that are mirror […]

I acquired an old fax machine that looked like a ripe source of parts, like steppers, IR sensors, micro switches and things.  As it turned out, it was.  It also had a nice looking 2 x 16 character LCD.  However, after taking everything apart, I found the LCD only had 13 pins instead of the […]

In our previous two tutorials (see here and here), we created a Simon-type game using the Arduino, a hardware platform for simple, and not so simple, electronics projects. We placed three buttons and three LEDs on to something called a breadboard, and wrote a small program that would send a random sequence to the LEDs, […]

This is a simple solar tracker which automatically orients itself towards the sun or any bright source of light like the sun .If you place solar panels on this robot it can increase their productivity by 90 to 95 %. At first creating a solar tracking robot may sound complicated but it quite quickly becomes […]
