Alternative Phone Charging Devices

We’ve all heard of solar cells that charge your devices, or the odd flashlight that charges when you shake it, but this style charger should be new to almost everyone. This “pan charger” is reportedly capable of charging a cell phone or other mobile device using a USB connection in 3 to 5 hours.  It also has a built-in radio and lantern. This should be a great tool for surviving a zombie apocalypse or if you simply live in a region without readily available power.

A second charger, currently being used in Africa, is an adaptation of a small generator hooked up to a bicycle. As this form of transportation is quite common in developing nations, this simple idea definitely shows promise.  Check out the video of the bike cell phone charger after the break. [Read more...]

Thermic lance made from spaghetti

spaghetti_thermic_lance

[Frogz] sent in a video he found of a thermic lance constructed from spaghetti. If you are not familiar, thermic lances are typically comprised of an iron tube filled with iron rods, which are then burned using highly pressurized oxygen. This lance however, was built by tightly wrapping a bundle of spaghetti in aluminum foil and attaching it to an oxygen tank. While thermic lances are commonly used in heavy construction where thick steel needs to be cut, [latexiron] and his friends use theirs to cut apart a chair. While we don’t necessarily condone drunken destruction of innocent patio furniture, we can’t help but watch this video again and again in amazement of the incredibly novel use of everyday pasta. You too can join in the drunken revelry after the jump. If food-based cutting torches are your thing, be sure to check out this bacon lance as well.

Flaming guitar hero

[Chris Marion] knew he wanted to play with fire, or more accurately with fireball spewing valves, but he need a good project in which he could use them. Inspiration finally struck and he built this controller that matches fireballs to the fret buttons on a Guitar Hero controller. There’s quite a lot that goes into this but we think that he hit a home run. The basic components are a manifold with electronically actuated valves, another manifold for the pilot lights, and a modified Guitar Hero controller.

To interface the controller he used an Arduino along with [Bill Porter's] PS2 library to read signals from the buttons. But the real labor intensive part of the build came with the manifold. There’s a hardware store’s worth of fittings and flexible copper pipe that go into that assembly. In the end this all came together in just one week.

Hacked AC and ash filter

Moscow is in a bit of a hot spot right now, dealing with a heat wave and enormous wildfires. The combination of smoke, ash, and heat was driving Andrew up a wall so he built a contraption to provide some relief. It has two chambers, the bottom houses ice water, the top is an air baffle. A small DC fan pumps air into the upper chamber where it encounters the water being sprayed in from the lower reservoir. What results is a heat exchange similar to other diy AC setups we’ve seen. But Andrew also notes that after running the device for a while the smell of smoke and ash is gone. Can this setup be seen as an effective way to trap airborne smoke particles?

Wiimote controlled Ruben’s tube

While we could be content following our “kiddie d-day” as [Caleb Kraft] suggested. We know you can’t continue such an awesome Friday without trying to blow yourself up first.

This Wiimote Rubens’ tube caught our eye. A PVC Aluminum irrigation pipe is drilled with holes and propane is pumped through. A speaker on one end creates changes in pressure and a neat light show follows suit. [ScaryBunnyMan] went further though, with a collection of software and a Wii Remote he “plays god” controlling the music, and thus, the fire. Check out a fun video after the split.

Turkey fryer; awful, bad, and worse

Tomorrow’s turkey day here in the United States. Do you fully expect your trashy neighbor to burn down his house while trying to cook a holiday feast? To see what’s in store for your neighborhood we’ve rounded up a great collection of idiots deep frying turkeys. [Read more...]

Improved arm mounted flame thrower

prometheus-flame-thrower[Everett] is at it again with Prometheus, an arm mounted flame thrower.This is the third generation of the project and makes some huge advances over the second generation we saw last year. We’d say he’s reached cinema/stage-performance quality with his design.

The self-contained system is completely arm mounted with a fuel reservoir mounting behind the elbow. The new version adds an adjustable flow valve actuated by a servo motor to regulate the flame size. An arc generator has been incorporated to replace the lighter from the last version. A microcontroller measures wrist angle and takes care of creating the arc and regulating the fuel supply.

Prometheus is small, controllable, and frightening. See a full demonstration as well as some video of the prototyping process after the break. Does this make you wonder how much burn cream [Evertt's] needed over the years?
