Default Lighting kits

Hi

Just getting some bits and pieces together before starting a 22'' Eagle build.

I am looking at adding some LED's around the model and wondered if there are any commercial LED driving circuits from Maplin / CPC / Ebay etc? Or do you all just run them permanently ON from a battery?

I buy flashing LEDs, flicker effect or static ones that just run directly from the battery without any complex circuitry.

Default Light up my (modelling) life.....

Go on then, Boldman, since you have our undivided, would you be able to furnish us with some detail? Behind my MPC 22" project sits the currently in-progress scratch-build "Evil Twin" 22", which will allow me scope to take a few risks, add things in and put my own individual stamp on the Eagle.

One of the obvious things would be to light the Command Module, and what you've briefly described is exactly what I'm looking for. As ever, you'll have enough to do without leading folk by the nose but, if you've a minute or two, please share!!!

Kindest regards

Patrick

For the most recent build I used 2 Surface mount LEDs which are tiny but very bright LEDs that come pre-wired with a resistor:



You can get these LEDs in batches of 20 from eBay for not a huge amount, eg

http://www.ebay.co.uk/itm/201482969362

I've also used flashing red, green, blue and yellow LEDs in other parts of the build. These again all come with resistors wired in. The static white LEDs need to have a resistor soldered on so I use 22 ohm resistors. All my LEDs are wired in parallel which keeps any resistor calculations nice and simple, but does mean the wiring can be a bit more complex

The most difficult part of lighting a model is where the power supply goes and how you get the power to the model from the battery. Check out my #3 eagle build for the hoops I'm having to jump through to achieve that - its not easy! For example, getting the power into the cockpit for the LEDs from the walkway while still allowing the removal of the 'beak' for transportation:



From my second Eagle build end of last year:

Thanks for taking the time to reply Boldman. That is exactly the kind of answer I was looking for I think i'll buy a selection from t'bay and start playing with them. Maybe throw in a trusty old 555 timer or two
