This custom-built golf club puts a new twist on POV (Persistance of Vision) systems. If you want to build your own, you’ll need a CUBLOC CB220, CUBLOC CB220 proto-board, 8 high-output blue LEDs, 1 empty semiconductor sleeve, 8 100 Ohm resistors, 9V battery, golf club, and a couple wires.” Full instructions here. Video after the jump.

As you can see, the letters will go backwards on the backswing and forwards on the forwardswing. Ben Hogan’s “Five Lessons” has a good picture of correct swing arc for a golf swing

So you’ve seen what spud guns are capable of, now find out how to make your own with this tutorial. Parts needed include, a cannon barrel, reducer coupling, end cap, female adapter, two clamps, hardware (nuts, connectors, etc.), stun gun, and wiring.

You can use the Night Lighter both day and night, but when it’s dark, the clear PVC provides an excellent view of the interior ballistics. Also, the stun gun gives better performance than weaker sparks from piezoelectric or flint/steel igniters. It’s fun both to fire and simply to watch in action

If you haven’t throw down for one of the bazillion iPod docks out there, you may have considered just making your own. But for those out there without the technical know-how — or more importantly, adequate funding — you’re probably stuck syncing your ‘Pod flat on the desk with that plain ole cable Apple tossed in. A dissatisfied (and apparently broke) Mac user finally felt that enough was enough, and resorted to creating an iPod dock from what appears to be an old Apple accessory box, a generous helping of tape, scissors, and a black marker. While we assume any smallish cardboard box would fit the bill, using the prior home of an AirPort Express card just adds that critical dash of Apple flair to the whole creation. If you’re a bit short on cash, or just admire your own handiwork, be sure to keep reading for an internal view, and then hit up the more info link to peep a full gallery of construction photos so you don’t screw yours up.

Heck yes. We’ve been trying to utilize our Lego collection for the production of projectile apparatuses ever since the Pirate sets stopped coming with those flickable cannons. Now it seems our sad attempts have been eternally showed up by Sebastian’s ULTIMATE Lego Chaingun, which has 8 barrels, a 64 shot capacity, and an eleven rounds per second firing rate. The rubberband chaingun took over a month to build, and is powered by an honest-to-goodness Lego motor. Sebastian has all sorts of ideas how to mod up his gun even more, including an ammo counter or even faster firing rate, but whatever he manages to do it’s clear all we’re going to be bringing to our next rubberband fight is a white flag.

We’ll forever be in awe of people like Alexei Karpenko, a modder who one day “decided to do a quick IDE to GBAMP hack”. That’s right — as a casual aside, Alexei hooked up a hard drive to his Nintendo DS via a GameBoy cartridge originally designed to play short movies from a CompactFlash card. The hack is apparently possible due to similarities between the CF interface and that of standard IDE hard drives: Alexei simply soldered the correct pins onto a 40GB disk and connected it to a 11.1 volt battery and 5 volt DC-to-DC converter. As you can see, the unwieldy setup isn’t much of a PSP rival (remember, that second “P” stands for portable), but the mere fact that it’s at all possible will undoubtedly impress your inner geek.
