This project requires some assembly skill, patience and a little solder. (I haven't written a manual yet, but it's on the way) I've done my best to create an item that can be assembled using common things like paper clips, etc., but you will still need a couple of solder joins. The parts you'll need to get are shown in the attached images, and can be obtained from Jaycar dealers in Australia, or direct from China via Ebay. UPDATE: found a supplier that sells these for about a buck: (you'll want the 4 Watt model that's 30mm diameter) http://www.aliexpress.com/item/1pcs-lot-free-shipping-1W-3W-4W-6W-G4-LED-5050-SMD-360-Degree-White-Car/32236326076.html The LED module has polarity correction, and a built-in regulator to make the best of the power as the volts drop, and is very easy to wire up. (pay attention to the alignment of the batteries - this is crucial; if you're unsure, just Google "series battery". All 8 batteries must connect + to -, except for the first and last cell, that go to the LED via the switch. (1.5v X 8 = 12v) Switches are not full of magic - they simply open and close two metal points. In this case, the centre pin is common, and toggles between both sides. You'll want a SPST (single pole single throw) with a 6mm neck and body depth of 13mm I used a combination of 3mm screws, ranging from 10mm to 12mm, and 30mm - all in stainless. No, I haven't had time yet to invent a tailcap or assembly tutorial, but feel free to leave me comments and ask questions until I do. (UPDATE: Tail Cap added!) One quick fix to cover exposed terminals on the base is to print a second tailcap and screw both on. Future mods will include a base with exposed terminals to facilitate a charging dock - not in this version, though! I'll add any extra mods as I go, like a pistol grip attachment that I've been considering. Requests welcome! Lastly, it's not "sodder" - it's "solder"! We Aussies speak the Queen's English... CAUTION!!! Seriously, even AAA batteries can start a fire or cause issues you didn't think of. Get educated, or be damn careful! And I'm not liable for your mistakes!
