If you do a lot of 3D computer work, I hear a Spacemouse is indispensable. So why not build a keyboard around it and make it a mouse-cropad? Image by [DethKlawMiniatures] via reddit That’s exactly what [DethKlawMiniatures] did with theirs. This baby is built with mild steel for the frame, along with some 3D-printed spacers […]
Although the video game crash of the mid-80s caused a major decline in arcades from their peak popularity, the industry didn’t completely die off. In fact, there was a revival that lasted until the 90s with plenty of companies like Capcom, Midway, SEGA, and Konami all competing to get quarters, francs, loonies, yen, and other […]
Over on his YouTube channel [Aaron Danner] explains biasing transistors with current sources in the 29th video of his Transistors Series. In this video, he shows how to replace a bias resistor (and consequently an additional capacitor) with a current source for both common-emitter and common-collector amplifiers. A current source provides electrical energy with a […]
At Hackaday, it is always clock time, and clock time is a great time to check in with [shiura], whose 3D Printed Perpetual Calendar Clock is now at Version 2. A 3D printed calendar clock, well, no big deal, right? Grab a few steppers, slap in an ESP32 to connect to a time server, and […]
Water is an excellent coolant, but the flip side is that it is also an excellent solvent. This, in short, is why any water cooling loop is also a prime candidate for an interesting introduction to the galvanic metal series, resulting in severe corrosion that commences immediately. In a recent video by [der8aer], this issue […]
China played host to what, presumably, was the world’s first robot and human half-marathon. You can check out the action and the Tiangong Ultra robot that won in the video below. The event took place in Beijing and spanned 21.1 km. There was, however, a barrier between lanes for humans and machines. The human rules […]
Forth is popular on small computers because it is simple to implement, yet quite powerful. But what happens when you really need to shrink it? Well, if your target is the 6502, there’s milliForth-6502. This is a port of milliForth, which is a fork of sectorforth. The sectorforth project set the standard, implementing a Forth […]
