The theory behind hydropower is very simple: water obeys gravity and imparts the gained kinetic energy onto a turbine, which subsequently drives a generator. The devil here is, of course, in all the details, as [FarmCraft101] on YouTube is in the process of finding out as he adds a small hydro plant to his farm […]
These days, you get a fantastic camera with the purchase of just about any modern smartphone. [Abe] missed some of the charm of earlier, lower-quality digital cameras, though, and wanted to recreate that experience. The way forward was obvious. He built a nostalgic digital video camera from scratch! [Abe] figured he could build the entire […]
The Amiga 600 was in its day the machine nobody really wanted — a final attempt to flog the almost original spec 68000 platform from 1985, in 1992. Sure it had a PCMCIA slot nobody used, and an IDE interface for a laptop hard drive, but it served only to really annoy anyone who’d bought […]
When you start an STM32 MCU with its default configuration, its CPU will tick along at a leisurely number of cycles on the order of 8 to 16 MHz, using the high-speed internal (HSI) clock source as a safe default to bootstrap from. After this phase, we are free to go wild with the system […]
Hopscotch is a game usually played with painted lines or with the aid of a bit of chalk. However, if you desire fancier equipment, you might like the interactive hopscotch setup from [epatell]. The build uses yoga mats as the raw material to create each individual square of the hopscotch board. The squares all feature […]
Cartridge-based consoles have often been celebrated for their robust and reliable media. You put a simple ROM chip in a tough plastic housing, make sure the contacts are fit for purpose, and you should have a game cart that lasts for many decades. When it comes to the Nintendo 3DS, though, there are some concerns […]
Once upon a time, transmutation of the elements was a really big deal. Alchemists drove their patrons near to bankruptcy chasing the philosopher’s stone to no avail, but at least we got chemistry out of it. Nowadays, anyone with a neutron source can do some spicy transmutation. Or, if you happen to have a twelve […]
Modern hospitals use a lot of computers. Architecturally speaking, they’re pretty typical machines—running the same CPUs and operating systems as any other PCs out there. However, they do tend to have some quirks when it comes to accessories and peripherals, as [tzukima] explores in a recent video. The video starts by looking at typical power […]
Over the years there have been a few CPUs designed to directly run a high-level programming language, the most common approach being to build a physical manifestation of a portable code virtual machine. An example might be the experimental Java processors which implemented the JVM. Similarly, in 1976 Itty Bitty Computers released an implementation of […]
Over on ScienceDaily we learn that an international team of scientists have turned a common semiconductor germanium into a superconductor. Researchers have been able to make the semiconductor germanium superconductive for the first time by incorporating gallium into its crystal lattice through the process of molecular-beam epitaxy (MBE). MBE is the same process which is […]
