Vacuum fluorescent displays (VFDs) are one of those beautiful pieces of bygone technology that you just don’t see much of anymore. At one time they were a mainstay of consumer electronics, but today they’ve largely been replaced with cheaper and more energy efficient displays such as LEDs and LCDs. While they might be objectively better […]

If you are a hardware DIY enthusiast who is interested in open source hardware and want to share projects and designs, you have to learn more about Upverter. Upverter is a web-based EDA (Electronic Design Automation) system which enables hardware engineers to design, share, and review schematics and PCBs (Printed Circuit Boards). It does for
After a youth spent playing with Amigas and getting into all sorts of trouble on the school computer network, I’ve always had a soft spot in my heart for hardware from the 80s and 90s. This extends beyond computers themselves, and goes so far as to include modems, photocopiers, and even the much-maligned dot matrix

The XCL206 series is a synchronous step-down micro DC/DC converter which integrates an inductor and a control IC in one tiny package (2.5mm×2.0mm, H=1.0mm). A stable power supply with an output current of 600mA is configured using only two capacitors connected externally. Operating voltage range is from 2.0V to 6.0V(XCL20xG:1.8V-6.0V). Output voltage is internally set in a

Libre Computer has successfully launched a smaller, less powerful follow-up to its Le Potato SBC, the “La Frite SBC. The La Frite SBC is a small version of the Le Potato SBC, that has a quad -A53, HD-only Amlogic S805X, a Raspberry Pi A+ footprint and GPIO connector, and mainline Linux support. The 64 x 55mm La Frite is roughly

Coffee machine manufacture Victoria Arduino is opening its new showroom in London on 28 March in collaboration with its local importer VA Machinery. Victoria Arduino’s showroom will introduce the company’s products to its United Kingdom partners at the River Thames near the London Bridge. The showcase will provide a space for roasters, baristas, technicians and
Firmware is a type of software that provides control, monitoring and data manipulation of engineered products and systems. A USB device firmware hack called BadUSB was presented at Black Hat USA 2014 conference, demonstrating how a USB flash drive microcontroller can be reprogrammed to spoof various other device types in order to take control of
Recently the hobbyist market has seen the appearance of the Air602 low-cost ARM WiFi module. This module might be a potential competitor of ESP8266, another low-cost powerful WiFi module, that took the electronics hobbyists by storm long ago and is still extremely popular. But what’s more interesting about the Air602 module is the usage of a completely

The $120 to $165 “SparkFun Autonomous Kit for Sphero RVR” extends the $250 Sphero RVR robot with an Raspberry Pi Zero W, a pan-tilt camera, GPS, and an optional ToF distance sensor. SparkFun Electronics recently completed a successful Kickstarter project for its Sphero RVR, a four-wheeled tank-treaded robot that offers optional programming via a Raspberry Pi,
RPi Zero W based robot kits offer pan-tilt cam, GPS, and ToF sensing Continue Reading
A feline’s appetite is rarely sated, and cat owners around the world are routinely treated to an early morning wake up call to remind them of this fact. To solve this problem, many turn to automated feeders. However, such devices usually handle only dry foods, with a simple hopper system. [Vikram Hao] instead went above
