In this episode of [Adrian’s Digital Basement], we dive into the world of retro computing with a focus on diagnosing and repairing an old full-height 5.25-inch floppy drive from an IBM 5150 system. Although mechanically sound, the drive had trouble reading disks, and Adrian quickly set out to fix the issue. Using a Greaseweazle—a versatile […]
Multiple motors or servos are the norm for drones to achieve controllable flight, but a team from MARS LAB HKU was able to a 360° lidar scanning drone with full control on just a single motor and no additional actuators. Video after the break. The key to controllable flight is the swashplateless propeller design that […]
Whether you’re a kid or a nerdy adult, you’ll probably agree that the interactive exhibitions at the museum are the best. If you happened to get down to the Oregon Science Festival in the last couple of years, you might have enjoyed “Catch The Wave!”—a public education project to teach people about electromagnets and waves. […]
I’m sitting at a table writing this in the centre of a long and cavernous industrial building, the former print works of a local newspaper, I’m surrounded by hardware and software hackers working at their laptops, around me is a bustling crowd admiring a series of large projects on tables along the walls, and the […]
What have you missed on Hackaday this week? Elliot Williams and Al Williams compare notes on their favorites from the week, and you are invited. The guys may have said too much about the Supercon badge this year — listen in for a few hints about what it will be about. For hacks, you’ll hear […]
We might consider PCB panels as simply an intermediate step towards getting your PCBs manufactured on the scale of hundreds. This is due to, typically, an inability to run traces beyond your board – and most panel generators don’t give you the option, either. However, if you go for hand-crafted panels or modify a KiKit-created […]
Up first this week is a warning for the few of us still brave enough to host our own email servers. If you’re running Zimbra, it’s time to update, because CVE-2024-45519 is now being exploited in the wild. That vulnerability is a pretty nasty one, though thankfully requires a specific change from default settings to […]
It’s fairly insignificant in the scheme of things, and there’s no hardware as yet for us to look at, but there it is. Tucked away in a device tree file, the first mention of a Raspberry Pi 500. We take this to mean that the chances of an upgrade to the Pi 400 all-in-one giving […]
Ever want a seriously powerful PCB for charging a Li-Ion pack? Whatever you want it for, [Redherring32] has got it — it’s a board bearing the TPS25750D and BQ25713 chips, that lets you push up to 100 W into your 1S Li-Ion pack through the magic of USB Power Delivery (USB-PD). Why do you need […]
What is with all the wasted space on keyboards? There’s a whole back side just sitting there doing nothing. But how can you use the back at the same time as the front? All the board sandwiches must be wired together like this, natch. Just when we think Google Japan can’t possibly produce another weird, […]
