Broken TV Brought To Life In LEGO Body

After letting it sit around for about 3 years, [Blake] decided it was time to fix his broken 15″ television. A little trouble shooting showed the problem was with the inverter. The backlight would come on for a few seconds, off for a few seconds, then repeat. By freeing the Magnavox 15MF400T from its metal case he got it working again, but couldn’t find the source of the short. His solution: build a new case out of non-conductive material. Voilà! We have the 15″ LEGO monitor.

It’s not a very complicated LEGO build, but it’s the first case mod we’ve seen in a long time that isn’t strictly gratuitous.  Join us after the break for more pictures. Continue reading “Broken TV Brought To Life In LEGO Body”

Halloween Prop: Portable Black Light

[Joshua] wrote in to show us this great Halloween tip. He wanted to take his 4 foot long black light along with him on Halloween. You can buy portable versions, but he realized he had enough parts laying around to slap together a portable one himself. He pulled the inverter from a scanner light and wired it up to a couple of 9 volt batteries. Knowing he would probably need a fresh set during the night, he actually wired in some extras with a switch to control which was powering the unit. We know this isn’t the best solution, but you could probably toss this together in just a few minutes.

Fiber Optic Flash Ring


Ring lights that surround the lens are generally used for macro photography – they’re not cheap, but they’re one of the few ways to get shadowless photos. This fiber optic flash diffuser is based on the same ideas of this one. Rather than use a few large optic strands, [Joris] is using many, many more to decrease shadows as much as possible. His previous efforts are even more interesting. He built a LED version – with serial connected LEDs and a step up switching power supply to drive them. Then he moved on to cold cathode fluorescent before moving onto the fiber optics.
