Umbella Spotlight

A project I made to keep the darkness off.

Youtube link:

It has an articulated baltic birch, maple and bamboo frame with 6 Luxeon Rebel 1000ma LEDs each putting out about 310 lumens, or 1,860lm for the set. For comparison, your average LED flashlight kicks out about 100lm or so. This thing is rather bright so the fedora is a safety feature as well as a fashion statement.

The wooden frame articulates, allowing the LEDS to pivot between fully inward facing to fully outward simply by raising and lowering the umbrella slider. This allows the umbrella to cast everything from a tight spot, to a wide doughnut of light.

Right now I am powering it off an 18v cordless drill battery, at full brightness I can get about 3 hours before I have to recharge it. The ultimate plan is to run a few cylindrical rechargeable cells inside a hollow metal handle.

Oh, and in real life it doesn't make that choir noise.... yet.

Tarn - Lightweight Canoe Plans

Finally got around to drawing up the plans for my lightweight canoe, click the image for larger. Or even larger here.

As a quick disclaimer, this boat was built with absolutely perfect stock, no run out, no knots, so I was able to pare down the dimensions of the parts to the minimum. This means that if you have any flaws in your materials it would be advisable to upscale the parts accordingly. The same goes for the rest of the design, it has a minimum of ribs and a minimum of redundancy. Paddle it accordingly.

Usual restrictions apply, Commercial usage of this design is forbidden. Personal use is allowed, up to two boats, but no reproduction of the boat or this design in exchange for money or goods is allowed. Also, if you do build one, send me an email and/or some photos:
