Resin 3D printing has opened up a whole new scale of resolution for hackers, but the technology can go still finer; commercial micro-SLA and two-photon polymerization printers can print items …read more Continue reading Printing Micron-Scale Benchies With Resin and Turmeric
Driven by a desire for privacy, customization, and lower costs, there’s growing interest in AI models which can be run on local hardware. Few of them go as far as …read more Continue reading Running Generative AI on an RP2350
If you want improve a model rocket’s performance, all the common options come with serious trade-offs: you could increase the motor’s size, which raises safety issues, or you could cut …read more Continue reading Tube Launch Boosts Rocket’s Performance
[soiboi soft]’s vacuum-driven dot matrix display is part suction gripper, part touchscreen, and altogether impressive. Its display capabilities are entirely shadow-based, with each pixel being made of a cavity behind …read more Continue reading Playing Snake with a Pneumatic Display
There’s plenty of substances that can theoretically be extruded from a nozzle, but only a regrettably small subset of them can actually be used for 3D printing. One limiting factor …read more Continue reading Support Bath Enables an Epoxy Benchy
Impressive as it most certainly is when an amateur fabricates a semiconductor, most of the projects we’ve seen are more demonstrations than workable chips. [Dr. Semiconductor], however, is going much …read more Continue reading Making LEDs in the Home Fab
Drone control links are, from a radio signals perspective, nothing short of amazing: using a transmitter capable of transmitting, at most, one watt, a protocol such as ExpressLRS (ELRS) can …read more Continue reading Open-Source ExpressLRS Receiver Reaches for Range
Unlike biological systems, which can use muscles, robots that try to imitate them don’t have particularly fast, powerful, compact linear actuators available. This puts walking robots at a particular disadvantage, …read more Continue reading Building an Actuator for a Walking Robot
Gears are usually the biggest contributors to backlash in a mechanical system, but they’re far from the only culprits. Ball bearings are a less obvious source of imprecision, since any …read more Continue reading Splitting a Ball Bearing to Cut Out Backlash
Lightning, despite being a common and readily-detected phenomenon, is nevertheless difficult to study. One reason is the difficulty of predicting when and where lightning will strike; tall structures do attract …read more Continue reading Triggering Lightning with a Rocket
