AEM10940 is a power management IC designed by e-peas to store power from photovoltaics (PVs) cells and thermoelectric generator (TEGs) into rechargeable power sources, such as Li-Ion batteries and thin film batteries. At the same time, it supplies the system with two different regulated voltages, the charging voltage and the system supply voltage. e-peas is […]

A while back, I added a fan controller to my Topward 6603A power supply. Later on, when I bought a used programmable power supply (PPS-2322) I had to do the same thing. Both of those builds were done on protoboards but I had a feeling that many of my other projects could use a similarly

Never before have we been so incredibly connected to one another than today; thanks to the prevalence of internet and mobile data networks. But the dimension of this connected world is finite and ends not far beyond the outermost cell phone tower. John Grant wanted to be connected to his friends and family all the

The potential competitor of ESP8266 wifi module will be available next week for just $2! Pine64, the manufacturer of the first $15 64-bit single board computer, is now preparing to launch “PADI IoT Stamp” RTL8710AF module. This module has the size of the stamp, a small 24mm x 16mm package with powerful specifications compared to

A group of developers in Elektor Labs have modified a high power wireless power transfer project, which originally developed by Würth Elektronik eiSos GmbH & Co. KG, an electronic and electromechanical components manufacturer in Europe, in an attempt to come up with an easy-to-achieve solution for wireless power transfer of more than 100 Watts without using any kind

A retinal prosthesis substitutes for the photo-receptor cells of the defective retina. It’s composed of a camera carried in spectacles; electronics that processes the camera information; and a matrix of microscopic electrodes implanted in the eye in contact with the retina. These electrical signals are carried to the brain by the optic nerve. With such

The speed of light in vacuum is a well-known universal constant and is considered to be the nature’s ultimate speed limit. No matter, energy, and information can travel faster than this speed. The speed of light has always been a topic of great interest and significance throughout history. In the course of measuring the speed

Sure thing, Elektor has published several designs of adjustable power supplies based on switching regulators, so we know that doing this properly in a reproducible way and without making things overly complex requires some serious head scratching. The anxiety may be reduced vastly though by a new adjustable synchronous buck regulator which uses a single

Description Chronio is an Arduino-based 3D-printed Watch. By not including fancy Wifi and BLE connectivity, it gets several months of run time out of a 160mAh button cell. The display is an always-on 96×96 pixel Sharp Memory LCD. If telling the time is not enough, you can play a simplified version of Flappy Bird on
