There are plenty of techniques and components that we use in our everyday hardware work, for which their connection and coding is almost a done deal. We are familiar with them and have used them before, so we drop them in without a second thought. But what about the first time we used them, we […]
Underfloor heating is a wonderfully luxurious touch for a bedroom and en-suite bathroom, and [Andy] had it fitted so that he could experience the joy of walking on a toasty-warm floor in the morning. Unfortunately after about a year it stopped working and the culprit proved to be its thermostat. A replacement was eye-wateringly expensive, […]
We like to pretend that wires are perfect all the time. For the most part that’s acceptable, but sometimes you really do care about those tiny fractional ohm quantities. Unfortunately though, most meters won’t read very low values. There are tricks you can use to achieve that aim, such as measuring low currents through a […]
Summer in the Northern hemisphere means outdoor cooking. Matches are old school, and you are more likely to use a piezoelectric lighter to start your grill. [Steve Mould] has one, but he didn’t understand the physics behind why it works, so he decided to do the research and share it in a video. The first […]
X-acto knives are popular as the scalpel of the craft world. Obviously, holders for the blades are available off-the-shelf, but you needn’t settle for store bought. [Ariel Yahni] set about making an X-acto handle of their own, and it shows just how quick and easy making your own tools can be. The blades are first […]
Over the last few years the open-source RISC-V microprocessor has moved from existing only on FPGAs into real silicon, and right now you can buy a RISC-V microcontroller with all the bells and whistles you would ever want. There’s an interesting chip from China called the Sipeed M1 that features a dual-core RISC-V core running […]
The ESP32 is well known for both its wireless communication abilities, as well as the serious amount of processing power it possesses for a microcontroller platform. [Robert Manzke] has leveraged the hardware to produce a Eurorack audio synthesis platform with some serious capabilities. Starting out as a benchmarking project, [Robert] combined the ESP32 with an […]
When Maker Faire Bay Area closed down early Saturday evening, the fun did not stop: there’s a strong pool of night owls among the maker demographic. When the gates close, the after-parties around San Mateo run late into the night, and Hackaday’s meetup is a strong favorite. This year Hackaday and Tindie joined forces with […]
Join editors Elliot Williams and Mike Szczys as they unpack all the great hacks we’ve seen this week. On this episode we’re talking about laser Internet delivered from space, unwrapping the complexity of Charlieplexed circuits, and decapping ICs both to learn more about them and to do it safely at home. We have some fun […]
Sometimes, rather than going the commercialistic route, it can be nice to make a gift for that personal touch. [Mahesh Venkitachalam] had been down this very road before, often stumbling over that common hurdle of getting in too deep and missing the deadline of the occasion entirely. Not eager to repeat the mistake, help was […]
