Odd question for here, but I can't turn anything up on google. What I want to do is buy circuit board components (i.e. a mini circuit board, resistors, wire, solder, LEDs, 9V battery connector plugs, mini switch etc.). I'm building a lighting kit for my RC car so I can drive at night. Will look ace. It's DAMN hard to find a shop for this online.

Anyone know of any UK stores that may have a website? I dont really want to import stuff of this cheap price (I'll be spending £30 tops really!). Google is an arse for finding this stuff!

Wow, that place is awesome! I could build an infrared laser with the stuff they have there!

Yes mate, this is a great site, and all the little components are cheaper than my sister! woohoo! Hooking myself with everything I need.

Thanks again for the linkage.

lol...
Maplin are awesome for electronics, you can also checkout Tandy; as they can often provide soem good stuff to.

Ok, I've ordered all the shizzles I need to make my RC hemi cuda shine brighter than the sun itself, but now I need to wire it up. Been looking at other RC lighting kits and basically I need to run a resistor for each one of my LEDs to get the input stats right. Anyone any good with this sort of stuff?

I'm using a 9Volt PPR style battery.
I'm wiring about 10 lights in parellel, each with their own resistor.
I need to work out what level of resistor to use for each light (the rear red are a different rating to the super bright whites at the front).

Time to get those maths/science skills cooking, or alternatively, suggest some more boffins to ask. I suppose I'm looking for an equation which takes into account what the LED can handle, and what the input voltage is (9V) and presents me with a resistor level in ohms that must be used to get the battery voltage/current down to what the LED needs.

Quote: "To calculate resistance. Ohms law is V=IR. Solving for R yields R=V/I


V is voltage in volts, I is current in amps, and R is resistance in Ohms. V is the difference between the supplied voltage and the required voltage
Since we're using milliamps instead of amps, we need a multiplication factor of 1000
Since we're using the difference in supplied voltage and required LED voltage we need to subtract. The formula becomes

R=(12volts -LED voltage required)/(current in milliamps)*1000

LED's are very tolerant. Once you've calculated the resistance, you will use the closest resistor you can find. "

Actually, found a resistance calculator PHP thing, but it's good to know the maths is that simple, and they both arive at the same result. Nice one.

Maplin is ok but it takes forever to get stuff here. I just order from www.newark.com I can get stuff overnight and cheap in the States. If anyone from the States want to know.

Sweet! I could build a auto-opening thingy for my room and add a key to it... I like the green button better though.

You know when you see words like "thingy", people are talking about high tech stuff.
