Thanks for the articles, this method will help me.
BUT, the "Texpert" at DSE gave the wrong advice.....crazy! All lights can be in series or parallel. But the voltage will vary according to the connection. Low voltage, say 1.5 for the parallel lamps and 3x that for series, 4.5v. Great idea to have DIY projects!

Techpert is 15yr old wollies employee who hardly knows what an ELL EEE DEE? is

Jaycar have a better idea, sometimes even then its a bit rough.. google is the best and all knowledgeable overlord

Nice article.
Rather than use two batteries in series and lose power with the 1k, it might be better to use just one battery with a lower value resistor like 150 ohms or wire the two batteries in parallel rather than series, that way battery life will be doubled and you won't waste power at the resistor. I'd suggest using a small potentiometer in series for brightness.
Any details on how to cut the perspex?
Will grinding the inner ring provide uniform illumination?
If the led's aren't going to stay on continuously, you could even use button cells in parallel although the holder will be a challenge.
Will give this a try
