Fresh hacks every day
In an effort to ease the process of soldering Ball Grid Array (BGA) chips at home [Roger] rigged up a hands-free solution for his hot air equipment. The main component in the build is an Aoyue hot air rework station that he already had in his workshop. He wanted an adjustable mount that would hold it steady when reflowing parts so he hit Amazon and bought a $14 articulated lamp. After ditching … [Read more...]
This toothbrush holder will make sure you're brushing your pearly whites for an appropriate length of time. The three cups serves as tootbrush storage, and detect when one has been removed. Once you start brushing your teeth the lights on the front and bell in the back count down the process automatically. The counting sequence starts when a weight sensor in the base detects a change caused by … [Read more...]
We keep seeing a lot of RGB lamps, but they're also constantly increasing in size and complexity. Take this rendition, which uses a lot of RGB LEDs and has smartphone control (translated). The lamp itself uses 31 RGB LEDs arranged in a sphere that organizes them into three vertical rings. They're all ganged together (not individually addressable) with one transistor per color. An Arduino board … [Read more...]
This chandelier is something we'd expect to see on sale in the local gallery store. [Starkec] made it a couple of years back and we just love the look. The materials are pretty common, and you can throw it together in an afternoon. The diffuser are made from clear glass soda bottles. After removing the labels and giving them a good cleaning, they were each set upside down and sprayed with some … [Read more...]
[Styropyro] did a great job of taking common parts and making an interesting item. He calls this his Tornado lamp, and it's made with stuff you probably have around the house -- well you might have to substitute more common glassware for that Erlenmeyer flask. The bulk of the hack is in the base. You'll find a laser diode pointed at a small scrap of mirror. That mirror is mounted on the center … [Read more...]
Ooooh, nice enclosure! This is a little motion sensing lamp which [Krazatchu] built a few years back as a Mother's Day gift. The PIR sensor is easy enough to see as the white dome on the front of the case. But look closely below that and you'll see the LDR which it uses to keep the thing asleep during the day. This is intended to save on batteries but the original version still ate through them … [Read more...]
[Alex] built an add-on board for his TI launchpad that lets him use it as a wireless controller for an RGB lamp (translated). As you can see above, the board has a pair of female pin-headers which make it easy to install or remove the board. This way you can use it for other projects without any hassle. The board itself doesn't have any buttons. Instead, [Alex] etched a two-sided PCB, … [Read more...]
