“Never Twice the Same Color” may be an apt pejorative, but supporting analog color TV in the 1950s without abandoning a huge installed base of black-and-white receivers was not an option, and at the end of the day the National Television Standards Committee did an admirable job working within the constraints they were given. As […]
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 […]
When programming for modern platforms, the restraints are different to those of 30 years ago. Back in the dawn of the microcomputer age, storage and RAM were measured in kilobytes. It simply wasn’t possible to store large amounts of graphical data, and even code had to be pared back at times. [reeabgo] found out some […]
Security cameras used to be analog devices feeding back into a room full of tiny screens and commercial grade VCRs. As technology moved forward, IP cameras began to proliferate. Early models simply presented a video stream and configuration page to the local network. Modern models aimed at the home market differ however. More often than […]
Air quality has become an increasing concern in many urban areas, due to congestion and our ever-increasing energy use. While there are many organisations that task themselves with monitoring such data, it’s also something anyone should be able to take on at home. [Chrisys] is doing just that, with some impressive logging to boot. The […]
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 German Enigma device has always been a fascinating gadget for hackers. We’ve seen various replicas and emulators created over the years, and it was recently even the subject of our weekly Hack Chat. But if you think about it it’s not really a surprise; the Enigma has the perfect blend of historical significance and […]
The SEGA Genesis (aka Mega Drive) was launched at the tail end of the 1980s, bringing a new level of performance to the console world. At the time, 2D graphics ruled the roost, outside a few niche titles here and there. Decades later however, the demoscene continues to work in earnest. The Red Eyes demo […]
There are a few open source autopilots available these days for quadcopters and fixed wing aircraft. Two of the most popular are ArduPilot and PX4, however neither is officially capable of working with unpowered aircraft. Despite this, [rctestflight] decided to run some experiments to see just how PX4 would fare when controlling a drone-launched shuttle […]
ANT+ is a wireless protocol specifically designed for use with sensors, and has similar functionality in some respects to Bluetooth Low Energy. It’s found a place among various bicycle equipment manufacturers, to connect smartwatches, cycle computers and electronic gear shifters. Of course, as soon as something becomes a defacto standard someone has to start coloring […]
