If you’re mounting solar panels, everybody knows the drill, right? Point them south, angled according to latitude. It’s easy. In a video which demonstrates that [Everyday Dave] is truly out standing in his field, we hear a different story. [Dave] has a year’s worth of data in his Solar Panel Showdown that suggests there are […]
The wheels on roller suitcases are one of their primary failure points. After the destruction of the wheel mount on her DIY suitcase, [Laura Kampf] wondered if it would be better to dispense with wheels altogether. To give her suitcase a lift, [Kampf] decided to turn it into a hovercraft so it couldn’t be stopped […]
We aren’t sure what [theglassman] is working on, but based on his recent projects, we think it is probably something interesting. He’s been decapping ICs, growing oxide on silicon substrates, and has built a tube furnace capable of reaching 1200 °C. What would you do with something that can melt cast iron? We aren’t sure, […]
Perpetual motion devices are either a gag, a scam, or as in the case of this particular toy that [Big Clive] bought on AliExpress, a rather fascinating demonstration of a contact-free inductive sensor combined with a pulsed magnet boost for the metal ball. A cool part about the device is that it comes with a […]
Once upon a time, home computers were low-powered enough that they barely needed any cooling at all. An Amiga 500 didn’t even have a heatsink on the CPU, while the early Macintosh got by with a single teeny little fan. Modern smartphones are far more powerful than these ancient machines, packed with multi-core processors running […]
While it is sort of disturbing, it is one of the best uses for a round LCD we’ve seen lately. What is it? Just [vishalsoniindia]’s SoulCage — a pendant that appears to have a poor soul trapped inside of it. Just in time for the upcoming spooky holiday. You can see the device in operation […]
When you think of “secret” agencies, you probably think of the CIA, the NSA, the KGB, or MI-5. But the real secret agencies are the ones you hardly ever hear of. One of those is the National Reconnaissance Office (NRO). Formed in 1960, the agency was totally secret until the early 1970s. If you have […]
Oh, Radio Shack. What a beautiful place you once were, a commercial haven for those seeking RC cars, resistors, and universal remotes. Then, the downfall, as you veered away from your origins, only to lead to an ultimate collapse. More recently, the brand was supposed to return to new heights online… only to fall afoul […]
For RC aircraft there are generally legal restrictions that require the craft to stay within line of sight of the operator, but an RC boat or car can in theory go as far as the signal will allow — provided there is ample telemetry to let the operator navigate. [Thingify] took this idea to the […]
If you were to troll your colleagues, you can label your office coffee maker any day with a sticker that says ‘voice activated’. Now [edholmes2232] made it actually come true. With Speech2Touch, he grafts voice control onto a Franke A600 coffee machine using an STM32WB55 USB dongle and some clever firmware hacking. The office coffee […]
