This month will mark the 50th anniversary of the Apollo 11 mission that brought to a successful conclusion the challenge laid down by President Kennedy only eight years earlier. Three men went to the Moon, two walked on it, and they all came back safely, in a dramatic eight-day display of engineering and scientific prowess […]
Regular Hackaday readers may recall that a little less than a year ago, I had the opportunity to explore a shuttered Toys “R” Us before the new owners gutted the building. Despite playing host to the customary fixture liquidation sale that takes place during the last death throes of such an establishment, this particular location […]
With all the hoopla surrounding the recent launch of the new Raspberry Pi 4, it’s easy to overlook another event in the Pi calendar. July will see the fifth anniversary of the launch of the Raspberry Pi Model B+ that ushered in a revised form factor. It’s familiar to us now, but at the time […]
There’s been a lot of news lately about the Long Now Foundation and Jeff Bezos spending $42 million or so on a giant mechanical clock that is supposed to run for 10,000 years. We aren’t sure we really agree that it is truly a 10,000 year clock because it draws energy — in part — […]
When designing a printed circuit board, there are certain rules. You should place decoupling capacitors near the power pins to each chip. Your ground planes should be one gigantic fill of copper; two ground planes connected by a single trace is better known as an antenna. Analog sections should be kept separate from digital sections, […]
If you move as a hardware hacker through the sometimes surprisingly similar world of artists, craftspeople, designers, blacksmiths, and even architects, there’s one piece of work that you will see time and time again as an object that exerts a curious fascination. It seems that designing and building a chair is a rite of passage, […]
When it comes to the quest for artifacts from the Space Race of the 1960s, few items are more sought after than flown hardware. Oh sure, there have been stories of small samples of the 382 kg of moon rocks and dust that were returned at the cost of something like $25 billion making it […]
When I got the call asking if I’d be willing to fly down to Kennedy Space Center and cover an event, I agreed immediately. Then about a week later, I remembered to call back and ask what I was supposed to be doing. Not that it mattered, I’d gladly write a few thousand words about […]
In several decades of hanging around people who make things, one meets a lot of people fascinated by locks, lock picking, and locksport. It’s interesting to be sure, but it had never gripped me until an evening in MK Makerspace when a fellow member had brought in his lockpicking box with its selection of locks, […]
Solder is the conductive metal glue that one uses to stick components together. If you get the component and the PCB hot enough, and melt a little solder in the joint, it will stay put and conduct reliably. But it’s far from simple. There are many different solder alloys, and even the tip of the […]
