Have you ever been hiking and needed to light up an entire side of a mountain, nup me either, but if you ever do YouTuber and compulsive DIY’er rctestflight has built a torch for such an occasion. Using 10 massive LED chips each drawing 100 Watts of juice this monster torch can throw out 90,000 Lumens of pure white light. A standard home LED bulb uses between 15 -30 LED chips (depending on the bulb) and uses between 10 and 20 Watts of power to produce a measly 800-1000 Lumens of light.
Presented for your viewing pleasure is one of the most extreme home-made torches seen in many years. Now that the hard work designing and assembling the torch is complete the fun can begin, working out what the hell to do with 90,000 Lumens of light power. Sit back relax and don’t forget to turn off the lights when you leave.

Many a great idea has moved from concept to working prototype under the roof of a modern man shed, a fortress of solitude for many. Two very good examples of the creativity that takes place in the shed have recently been demonstrated to the world. Two variations on the always impressive electromagnetic rail gun.
Ziggy Zee and his band of electromagnetic enthusiasts are fist up with their rail gun powered by a series of 9 volt batteries. Don’t underestimate the power of the Duracell however, the heavy weight gun fires chunks of aluminium with 27,000 joules of power. Still not up with BAE’s rail gun that fires with 33 mega-joules of power but it is enough to wreak havoc on pumpkins and mobile phones. Certainly enough power to make you want to stand clear when firing.
Next up Alex Smyth and friends assembled something a little bit different, a rail gun that fires plasma bullets. Instead of using a slug of lifeless aluminium as the projectile the Alex rifle uses a coper sleeve with a capsule of Zeon gas inside. As the Zeon capsule passes through the rail gun it becomes excited and turns into a plasma gas able to piece steel plate. An altogether impressive piece of home-made kit.
Presented for your viewing pleasure are the spectacular test firings of two new home-made rail guns. Demonstration videos that highlight the power of a good man shed and some electricity. Sit back relax and prepare to be impressed by the magical power of magnets.
