Super Affordable LED Lighting Ready to Go Off Mains Voltage

lights

If you’re looking for a super cheap way to add LED lighting accents to your house, then this hack is for you! Corn-cob style LED light bulbs can be had for a few dollars. The bulbs include driver circuitry, and 8 LED arrays! All you have to do is take it apart.

[Martin Raynsford] stumbled upon this idea when trying to think of a way to light his laser engraving enclosure. It originally came with a regular light bulb, but it didn’t distribute light nicely and was in the way for some of his other planned upgrades.

Not wanting to add another DC power supply to the mix he remembered an old corn-cob LED light bulb he had — as it turns out, they’re pretty easy to take apart! Solder some longer leads on (take note of how they are wired, some are in series, some in parallel) and you’ve just made yourself some easy to use LED accent lighting!

Of course you could just buy those cheap LED rolls from China nowadays for next to nothing for your accent lighting.

LuxBlaster: Blast a Beam of Light at the Most Intense Light Source

HighBeams

[Hazim] wrote in to tell us about his project that teaches inconsiderate drivers a lesson! Well, theoretically. The LuxBlaster is a spot light which points towards the most intense light source.

The idea is that you can blast drivers who do not turn their high-beams off with a reverse high-beam of your own. It is very important to note that this should never be used, as [Hazim] also clearly states. While this project is meant to prove that it can be done (a “what if”) project, it has two components that are very well done and can easily be used in different projects: the Arduino controlled spotlight and the light intensity tracker.

What would you use an Arduino controlled spotlight for? Smart lighting? What about a light source tracker? Let us know in the comments.

Google? In my lightbulbs? It’s more likely than you think

led_lighting_by_google

With the recent announcement and release of their ADK, it was only a matter of time before Google started invading your home in a big way. From the looks of it, Google will be jumping into the home lighting market very shortly, which could prove to be quite interesting.

Partnering with Florida-based Lighting Sciences, Google is planning on developing consumer-grade 60W equivalent smart LED light bulbs. The bulbs will be able to wirelessly communicate using Google’s new open-source home networking protocol. The lights will be controllable using any Android device allowing users to dim, brighten and toggle the lights on and off without ever touching a wall switch.

We think it’s an interesting idea, and we’re all for getting quality LED lighting in the home. That said, some of Google’s other utility-centric endeavors such as PowerMeter have met only mediocre success, so it remains to be seen if this concept takes off. If it does however, we can’t wait to see the flood of ADK-based hacks the community puts together. Since their new wireless protocol will likely be extended to all sorts of other household systems, the possibilities are endless.

Oven parts scrounging

In response to last week’s post about parts scrounging with a heat gun, Hackaday forum member [BiOzZ] decided to try doing the same thing in his oven. It seems to work quite well, but we’re wondering if there should be any concerns over the lead content of the solder. Anyone care to chime in?

Spill-proof parts holder

Have you ever been in the midst of disassembling something and knocked over your container full of screws onto the floor? [Infrared] has a simple solution to the problem which also happens to keep a couple of plastic bottles out of the landfill.

Easy button stops abuse of the word awesome

Do you often repeat a word ad nauseam? Make author Matt Richardson does, and he hacked a Staples “Easy” button to help him break his addiction to the word “Awesome”.

Cheap Remote-controlled baseboard lighting

[Sean] scored a pair of LED deck lighting kits for a steal and decided to install them into his newly renovated kitchen. They are currently remote operated, but he plans on adding an X10 interface as well as PIR sensors for automatic triggering in the near future.

Yet another LCD recapping guide

It starts with a finicky backlight, or perhaps a high-pitched whine from the back of your display – by now, we’re sure that everyone knows the symptoms of an LCD panel that’s just about to die. [Eric's] Syncmaster recently quit on him, so he pried it open and got busy recapping. It’s running again, and he wanted to share his repair process in case others out there own the same display.
