Hi all 
Looking for some advise looking to my next project Bae hawk 1/32 was thinking of putting lights into this kit 
Has any one any experience with this been looking on the web and found this kit 


how hard is this to build your own as i think the led's will be a bit big for this model 
Any thoughts or hints would be much appreciated 
many thanks

Hello mate.
I've done some models with lighting, but with not so advanced electronics (micro controllers etc).
I used a source voltage, leds, resistors (to not burn the leds) and fiber optics.

3 simple things:

1) Leds are diodes and you need to put some resistors,u dont connect them directly into voltage.Otherwise leds will be burn out in short period of time. The resistor you need can be calculated here: 

2) In a simple circuit (simple circuit contains leds,resistors and battery nothing else) you cannot combine diff types of leds.Because Red leds have different Consumption than whites etc.And then your circuit wont work.In a microcontoller circuit diff types of led can be combined.

3) You need the specs of your LED, each LED type is different. Typically the current is around 20 mA and the Voltage is:

The draw back of a simple circuit is that lights are on or off. But there are some leds on the market that blink automatically when you connect em on battery (with no controllers)

You need a controller for that rhythm, if you find something on ebay let us know [smile]

looking into this further found this control unit for writing to the chips 
http://www.ebay.co.uk/itm/PIC-MCU-JDM-Programmer-for-Microchip-IC-PIC16F84A-/251298482986?pt=LH_DefaultDomain_0&hash=item3a828e8b2a


Just got some reading up on how to program the chips to what you want them to do

You rolling into deep!

Maybe a pre-programmed chip or controller do better.[rolleyes]

Been reading up on programming http://www.lirtex.com/tutorials/beginners-guide-to-microchip-pic-programming/

I've ordered the kit off ebay see what size the led's are will update once that turns up and see if i can fit smaller size led's to that set first if need be [biggrin]

I may be out of turn here but this site has a lot of builders that do lighted models. Sure they know pretty much anything about it??

Chat to Bernie Potrell at wiredfx.co.uk. Although he mostly does sci-fi lighting he can give advice or design a custom light set up as well. And he's in the UK!
