Fresh hacks every day
Annoyed that the new lights he bought for his apartment lacked power switches, Instructables user [p.arry.drew] decided to install a pair of wireless light switches. Not content to use the remotes separately, he decided to see if he could cram them both into an old NES controller, making for a nice all-in-one wireless light commander. He disassembled the light switch remotes, cutting off a bit … [Read more...]
When the power goes out at home, what do you do? Most of us probably scramble around the house looking for a flashlight. [Gigawatts] wanted a better solution, so he built an emergency lighting system based off a standard household UPS. A while back he had constructed a relay-switched outlet box to help periodically restart his cable modem which would get hung up a little too often for his liking. … [Read more...]
[Joel] has a very specific color temperature of lighting he wants in his home. So specific, he's decided to build his own LED lighting to get it. Actually, he's still searching for that perfect shade of white, but doing so has learned a lot. He initially made some very pretty PCBs, but then found that hand soldering them made quite a mess. What better time to delve into reflowing? He shares his … [Read more...]
[Lucas] is at it again this year. Not satisfied by the computerized systems available on the market, [Lucas] decided to build on last year's project. To save a bit of cash, he built the setup around Parallax's low-cost SX28 proto board. The system is capable of controlling 102 channels, with 8-bit dimming. 6 boards control 7 channels each and are communicated to through a serial protocol … [Read more...]
[woody1189] put together some automatic lighting for his closet. Nine LEDs are grouped into three lamps and controlled by a hall effect sensor. He prototyped this on an Arduino and then migrated over to an ATtiny85. Although the current implementation could be accomplished without a microcontroller, we'd love to see some firmware improvements such as an auto shutoff for when you forget to close … [Read more...]
Current fluorescent lamps are great for lighting large areas using very few Watts; however, LEDs are far more efficient at producing light and have less of an impact upon the environment considering there is no mercury within them. [Andrew] sent in his team's LED florescent bulb. The first revision utilized 87 LEDs, but to increase output the second revision uses 210. The assembly can't actually … [Read more...]
[Synoptic Labs] stumbled upon an RGB light strip with individually-controllable LEDs. The strip uses 5 volts and is controlled by an HL1606. Because the strips are hard to find, this chip is mostly undocumented and he had trouble driving the strip. He was unable to get it working until he met with [John Cohn], who had previously reverse-engineered the serial protocol. Working together, they … [Read more...]
