In today’s value-engineered world, getting a decade of service out of a cordless tool is pretty impressive. By that point you’ve probably gotten your original investment back, and if the …read more Continue reading Unusual Tool Gets an Unusual Repair
Any project that contains something called a “flux modulator” instantly commands our attention. And while we’re pretty sure that [Retsetman] didn’t invent it after hitting his head on the toilet, …read more Continue reading Magnetic Gearbox Design Improvements Are Toothless but Still Cool
While wheels might seem like a foundational technology, they do have one major flaw: they typically need maintained roads in order to work. Anyone who has experience driving a Jeep …read more Continue reading Tracked RC Vehicle is (Mostly) 3D Printed
Placing two motors together in a shared drive is a simple enough task. By using something like a chain or a belt to couple them, or even placing them on …read more Continue reading Differential Drive Doesn’t Quite Work As Expected
It’s the same on Mars as it is here — just when you’re getting used to your job, the bosses go and change things up. At least that’s our read …read more Continue reading Ingenuity Completes Fourth Flight on Mars, Gets a New Mission
Security researchers have released a decryptor that enables victims of the Planetary ransomware family to recover their files for free. Released by Emsisoft, this decryptor requires a victim to have a copy of the ransom note. It’s not hard to fin… Continue reading Planetary Ransomware Victims Can Now Recover Their Files for Free
Stepper motors are a staple in all sorts of projects, but it’s often the case that a gearbox is needed, especially for applications like the linear drives in CNC machines and 3D printers. In those mechanisms, a high-torque, low backlash gearbox might be just the thing, and a 3D printable split planetary harmonic drive for the popular NEMA 17 motors would be even better.
Right up front, we’ll say that we’re skeptical that any plastic gearbox can stay as backlash free as [SirekSBurom] claims his creation is. But we can see the benefits of the design, and it has some …read more
