Hackaday ☛ Rapid Prototyping PCBs With The Circuit Graver
Walking around the alley at Hackaday Supercon 2024, we noticed an interesting project was getting quite a bit of attention, so we got nearer for a close-up. The ‘Circuit Graver’ by [Zach Fredin] is an unconventional PCB milling machine, utilizing many 3D printed parts, the familiar bed-slinger style Cartesian bot layout and a unique cutting head. The cutting tool, which started life as a tungsten carbide lathe tool, is held on a rotary (‘R’) axis but can also move vertically via a flexure-loaded carriage driven by a 13 kg servo motor.

Hackaday ☛ Hardware-in-the-Loop Continuous Integration [Ed: Outsourcing to Microsoft's proprietary prison, GitHub, is anything but "open" and it is utterly foolish]
How can you tell if your software is doing what it’s supposed to? Write some tests and run them every time you change anything. But what if you’re making hardware? [deqing] has your back with the Automatic Hardware Testing rig.

Arduino ☛ This Flip-Pelt wearable concept enables ultra-fast thermal feedback in VR
The Flip-Pelt wearable device relies on Peltier elements to create heating and cooling effects, which is a common strategy for thermal feedback. Peltier elements use electricity to produce thermal transfer, heating one side of the element while simultaneously cooling the other side. By placing a Peltier element against the skin, it is possible to create a cooling or heating sensation on demand.

Purism ☛ Freedom of Choice vs. Oppression of Big Tech
As Purism grows and our market share grows, our goal is to compete at the large scale and be a convenient privacy-respecting alternative.

J Pieper ☛ moteus configurable motor thermistors
When operating a moteus controller with a brushless motor there are two main things that can get hot: the FETs (field effect transistors) on moteus and the motor itself. By default, moteus has built in thermal throttling and fault detection if the FET temperature exceeds rated limits. In many configurations, the motor can be thermally connected to the moteus controller, so that the same FET temperature sensing can be used to prevent damage to the motor, but that isn’t always the case.
To help prevent damage to the motor, all current moteus controllers (n1, c1, and r4) have solderable pads that allow a thermistor mounted on the motor to be connected. Unfortunately, this has been less useful than intended for two reasons, one of which has recently been removed.

Raspberry Pi ☛ Meet Kari Lawler: Classic computer and retro gaming enthusiast
Kari Lawler has a passion for retro tech — and despite being 21, her idea of retro fits with just about everyone’s definition, as she collects and restores old Commodore 64s, Amiga A500s, and Atari 2600s. Stuff from before even Features Editor Rob was born, and he’s rapidly approaching 40. Kari has been involved in the tech scene for ten years though, doing much more than make videos on ’80s computers.

Hackaday ☛ Clever Circuit Makes Exercise Slightly Less Boring
We say this with the greatest respect, but [Joel] — your exercise routine is horrible! Kudos for getting up and doing something, but 108 trips up and down the stairs? That sounds like torture, not exercise. Even [Joel] admits that it’s so boring that he loses count, and while we’d bet that he isn’t likely to restart the routine when that happens, it’s still annoying enough that he built this clever little lap counter to automate the task.
