Here's my first Instructable, A waterproof rechargeable led Light suitable for work or great for camping. It's pretty simple to make with a few materials and parts, most of which i purchased off Ebay. Any kid who picks this up and turns it on instantly becomes Darth vader waving it around like a idiot :)
The Light is made of a Piece of PVC pipe with 5 metres of strip LED's wound around it, inside it contains 11 'mini" C Size rechargeable batteries, a pipe cap seals one end, while at the other the cap contains a waterproof on/off switch, recharging is done by 2 points on the body ..... more will be explained ..... so read on.
Step 1: Gathering The Parts
First off lets look at materials required:
Length of 30mm nominal bore PVC pipe 470mm long is finished length, but buy a metre anyway
A 5metre roll of cool white waterproof LED's - do a ebay search - about $18AU
2 x 30mm PVC end caps
1 x Waterproof switch
11 x 1.2v mini C size rechargeable batteries with TABS - again on ebay - 12pack for around $25AU
about 400mm of clear plastic hose that will fit neat in PVC, i think it's 25mm bore size
plus a few bits of wire, joiners, a couple of 5mm PEEL type pop rivets
beside this you will need some way of recharging the batteries. I use the NiCad charger from my model helicopter.
