[Antoine] wrote in to let us know that he soldiers on with his flashlight project. He’s doubled up on the supercaps and tripled the LEDs (translated). The core concept has stayed the same since the original version. He wanted a flashlight that was small and used no batteries. This iteration came about as he looked at [...]

Flashlights are so 20th Century. Be it the incandescent type that popped up very early on, or LED models with came around in the 90′s, there’s not much excitement to the devices. But [Sriranjan Rasakatla] is doing his best to change that. This is his WAY-GO Torch, an intelligent flashlight (a Smart Light?) that will [...]

You’re out at night and playing a boisterous game of flashlight tag. But how can you tell if you’ve been mortally wounded by your opponents light beam? [Kenyer] solved this problem by building a flashlight tag damage sensor which is worn by each participant. It adds a bit of the high-tech equipment used with laser [...]

In case you missed them the first time, here are our most popular posts from this past week. Our most popular post was about a ‘flashlight’ build. We are using the word flashlight loosely since this monster can draw up to 500 Watts! Our next most popular post was about another [Jörg Sprave] project where [...]

[Holzleim's] flashlight build is quite impressive. And the rise and fall of the hardware is quite a story. He designed it as a handheld light, relying on batteries to power a multitude of high-power LEDs inside.From the collection of four 5350 mAh lithium polymer cells he was able to achieve a peak power output that [...]

Odd project materials [Juliansr] wrote in to tell us about a site that sells bendable, moldable, stretchable, and other ‘able’ materials you might want to use in your next project. (2 * 9V) = Flashlight [Lasse] built a flashlight with two 9V batteries. One is a normal battery, the other has been gutted and is [...]

We know that you can transform the mechanical motions of your body into electrical energy, like when you turn the crank or shake a mechanically-powered flashlight. These types of mechanical motions are quite large compared to many of the day-to-day (and minute-to-minute) actions you perform–for example walking, breathing, and thumb wrestling. What if we could [...]

[Robbtoberfest] has earned our admiration with this crazy chainsaw powered spot light. It looks horribly dangerous, extremely inefficient, and woefully under engineered. We absolutely love it. This could be plucked from a video game or a movie and seems to be one UV bulb away from being the ultimate post apocalyptic zombie vampire Armageddon weapon. [...]

Building an LED flashlight is simple, right? Take a battery, connect it to an LED by way of a resistor. Alright wise guy, now make one that steps up the voltage for multiple LEDs and don’t use a boost-converter IC to do so. [fede.tft] shares a flashlight built inside of a  used glue stick case. [...]

When [Neelandan]‘s cheap flashlight’s internal rechargeable battery died, he scrounged for a replacement. Ultimately, the brightness of the light suffered with his new battery, taken from an old cell phone since he had dropped the voltage a bit. Upon inspection he saw that he would have to swap the individual resistors for each lamp to [...]

Going camping? You’ll need an extra backpack to carry this flashlight along the way. On the business end you’ll find 500 five millimeter super-bright white LEDs, on the opposite end there’s ten times the number of controls you’d expect on a flashlight. At full power, the LED array pulls down 50 Watts, making us question [...]
