Collaborate Disseminate
How cool would it have been if arcade cabinets had acrylic panels all along that let you gaze upon the field of TTL chips within? When [Jürgen Müller] scored the innards of an original 1972 PONG machine, that’s exactly what …read more
Spec sheets are an important tool in determining the performance of a given part or system, but they’re not the be all and end all when it comes to engineering. However, specs alone don’t prove whether a given system can …read more
It’s long been common wisdom that one of the safest places to keep your cryptocurrency holdings is in a hardware wallet. These are small, portable devices that encrypt your keys and offer a bit more piece of mind than holding …read more

PCI Express (PCIe) has been around since 2003, and in that time it has managed to become the primary data interconnect for not only expansion cards, but also high-speed external devices. What also makes PCIe interesting is that it replaces …read more

With so many smaller and more capable microcontroller boards on the market it’s now fairly safe to say that the classic Arduino footprint and form factor is rather outdated. That’s not to say that there’s no fight left in the old contender though, and to prove it here’s a new …read more

[Mark Aren] purchased a pair of Turbomolecular pumps (TMP) sans controllers, and then built an FPGA based BLDC controller for the Turbomolecular pumps. A TMP is similar to a jet turbine, consisting of several stages of alternating moving turbine blades and stationary stator blades, and having turbine rotation speeds ranging …read more

By pretty much any metric you care to use, 2020 has been an unforgettable year. Usually that would be a positive thing, but this time around it’s a bit more complicated. The global pandemic, unprecedented in modern times, impacted the way we work, learn, and gather. Some will look back …read more
For as many of them as we’ve seen, we still love a good persistence of vision display project. There’s something fascinating about the combination of movement and light creating the illusion of solid surfaces, and there’s always fun to be had in electromechanical aspects of a POV build. This high-resolution …read more

One of the exciting trends in hardware availability is the inexorable move of FPGA boards and modules towards affordability. What was once an eye-watering price is now merely an expensive one, and no doubt in years to come will become a commodity. There’s still an affordability gap at the bottom …read more
A fact universally known among the Hackaday community is that projects are never truly done. You can always spin another board release to fix a silkscreen mistake, get that extra little boost of performance, or finally spend the time to track down that weird transient bug. Or in [ultraembedded’s] case, …read more
