With the diffusion of the IoT (Internet of things) and the numbers of Wi-Fi and wireless nodes continuing to grow together the applications requiring power (more than you can do with a battery and/or an ultra-low consumption node), the idea of using only one cable to bring connectivity and power – especially to a large number of […]

The EVLSTCH03-45WPD 45W USB Type-C® Power Delivery 3.0 adapter from STMicroelectronics is a USB-IF certified solution and reference design. The EVLSTCH03-45WPD is an isolated ac-dc power supply with a standalone USB PD controller. The board implements at the primary side a quasi-resonant flyback converter based on the STCH03 controller with optocoupler feedback for voltage regulation. This controller combines a high-performance low-voltage

Though the sizes of laptops and mobile phones have become smaller and lighter over the years, that of power adapters have pretty much remained the same. They are still the same device we have always known them to be; bulky, messy and hard-to-carry-around. But the new GaNtechnology seeks to bring a revolution in the world of power
WORLD’S SMALLEST AND MOST AFFORDABLE 65W GAN ADAPTER FOR LAPTOPS AND MOBILE DEVICES Continue Reading
Modern devices are quickly switching to USB-C power adapters, gradually fading out USB-A, and USB-B adapters. USB’s Power Delivery (USB-PD) protocol enables the supplies to be flexible enough to handle charging (or powering) devices ranging from mobile phones to laptops. There are many high quality 90-100 Watt USB-C power adapters available. But unfortunately, there are many devices that

Texas Instruments’ power-path management solution features 20 mA termination and 1 A boost operation Texas Instruments’ BQ25619 integrates charge, a boost converter, and voltage protection in a single device. It offers ultra-low termination current for switching chargers to charge wearable devices by full-battery capacity. The BQ25619 low quiescent current reduces battery leakage to 6 µA in ship-mode, which conserves

Singapore-based startup Kobol has successfully launched its open-spec “Helios4” NAS (network-attached storage) SBC and fanned system. In May 2017, Kobol tried to launch the open-spec Helios4 SBC and fan-equipped system for NAS on Kickstarter. Though a total of 337 backers helped to raise $74K for the Helios4, Kobol fell short of its $110K funding goal. The Helios4 NAS SBC

How to build your own VGA-adapter My lifetime project: building an 8-bit computer using Z80 CPU. This week I had a bad flu and could not do anything useful so I decided to dig up my old plans for this project. I first re-designed many things, like power, CPU-board, IO-board and so on (my old

In this project I will show you how I repurposed two old camera tripods in order to create a motorized camera slider. The mechanical system consist mostly of aluminium and stainless steel which makes the slider sturdy and pretty decent looking. The electrical system consists of an Arduino Nano with LCD, rotary encoder, limit switches
