HELP!!! Led buying blunder. any ideas?

I've just purchased 100 leds for ten pounds. Woo. Just about to heat up my soldering iron, and BUGGER. I realised that instead of buying 100 ultra bright white leds, I've bought 100 ultra bright U.V. leds. (No wonder they were so bloody cheap!) I need ideas for a project. I suppose I could just make a big assed black light and rave the night away while getting a healthy dose of arc eye, but where's the fun in that...?

Which RF filter do I need for Tesla coil line protection? Answered

How do I determine what voltage and amp rating my RF line filter should be? I'm building a modest Tesla coil, powered by an automobile ignition coil  and must buy an RF line filter for my house mains, but there are so many differently rated filters for sale. I suspect that I can get by with a 120 volt, 10 amp rated filter for my U.S. house current, but all the ones online are rated for 240 volts. Can I still use 240v, and what amp rating?

I was shocked by the postage prices for Ponoko ($80 minimum on a $7 part) is there anywhere in the UK that will let you print one off items with small minimum orders. Or any way I can get something printed and keep the cost under £20?

help on designing a 12v UPS? Answered

We have a problem with kids coming into our garden, vandalising our plants, breaking into our shed etc. we have decided that installing a cctv system in our home is a good idea as even if it doesn't stop them coming in, it will be solid evidence to take to their parents. problem is, we have regular power cuts and i would like the cctv to be recording 24/7/365 (especially in the shed because that is where our bikes get stored) i have two 12v 7ah SLA batteries that i am donating to the project, iknow that they need 13.8v and around 500ma to charge. i need 16 camera outputs, and then a couple of spare outputs for aux devices (router to keep it connected to the internet, mics, infra red lamps etc) the dvr its self wants 12v 5 amps input so i think for that i will make another psu just for that with maybe 2 or 3 12v 7ah sla batteries. i have baisic electronics knowledge, have access to pcb printing facilities and can use eagle. any help at all would be amazing, the main things i need to know is: how to get 13.8v from 240v ac, how to power all the cameras from 240v ac and have a smooth switchover from mains to battery. thanks in advance - luke
