[Peter Demchenko] wanted to use a low power TS555 in an ESR meter design. The problem is, he needed to handle significant current sink requirements for cases where the capacitor …read more Continue reading Humble 555 Gets a Boost for ESR Meter
Last time I tried to convince you that, if you haven’t already, you should try running your 3D printer with Klipper. There are several ways to actually make it work. …read more Continue reading 3D Printering: Switch and Klip(per)
While classroom learning isn’t for everyone, one awesome benefit of the Internet is that you have a variety of college classes available to you, even if they aren’t for credit. …read more Continue reading College Gives You Practical Electronics
I have several 3D printers, and I’ve always been satisfied with using either Repetier or Marlin on all of them. There are a few other firmware versions that could run …read more Continue reading 3D Printering: Klipper, the Free 3D Printer Upgrade
Using a disk drive today is trivial. But back “in the day,” it was fairly complex both because the drives were simple and the CPUs were not powerful by today’s …read more Continue reading Everything You Wanted to Know about Early Macintosh Floppies
In the early days of 3D printers, most builds used smooth rods and bearings that rode on them. But these days, printers are shipping with either V-slot extrusions with Delrin …read more Continue reading V-Slot Wheels or Linear Rails?
You’ve probably heard that a 3D printer is capable of producing its own replacement parts. Sometimes, that even includes upgraded or improved versions of the parts it was originally built …read more Continue reading Simulating Air Flow for 3D Printing
In a modern car, your speedometer might look analog, but it is almost certainly digital and driven by the computer that has to monitor all sorts of things anyway. But …read more Continue reading Tech in Plain Sight: Speedometers
For decades, the magnetic stripe has been ubiquitous on everything from credit cards to tickets to ID badges. But the BBC reports — unsurprisingly — that the mag stripe’s days …read more Continue reading Farewell Magnetic Stripe
If you’re like us, you’ve studied the mathematician [Euler], but all you really remember is that you pronounce his name like “oiler” and not much else. [Welch Labs], on the …read more Continue reading Ask Hackaday: How Can We Leverage Tech for Education?
