This is not my idea, but I can't find the original post or poster where I originally saw it on Facebook to give them credit, but it is certainly well deserved. The gist is - battery powered, flickering yellow tea-light candles - less than a fiver for 12 on Amazon, half kilo bag of padding material (for stuffing toys) less than £3.00 delivered on eBay (I just used a small fraction of it here), Pound Shop grey primer and matt black spray paints (guess how much each?!) and my old Revell 1/32 Zero - because it was the closest to hand. This is just a quick build-up demonstrator if you like. Now I will work it into a few full-on dioramas of various scale and add red and yellow paint to the explosions as the OP did.

I've posted a short video of the same thing here:

but I'm not sure if everyone (who wants to) will be able to see it - please let me know.
Cheers
Al.

That would make for a terrific Age of Sail battle diorama.....

I shall have to experiment with this over the weekend.
I want to add some explosions to a WW1 diorama and I've been looking at some other ideas.
Perhaps all of them mixed up will do the job.

Have you looked at the Arduino micro computers, that cost anything from £2 upwards, you can programme them to flash LEDs randomly and run off any thing from 5v to 20v.

I have programmed one to illuminate a card shop that came free with a model railway mag, on the ground floor it has two white LEDs that are on all the time, on the second floor there are three LEDs red, blue & green, each of them flashes at random flicker rates and brightness to represent TV flicker and on the top floor I have 1 LED that comes on and off every 30 seconds.

The Arduino mini I use is only about the size of the top of you thumb and runs of a simple 9v battery.

Programming the Arduino is simple using free software and a USB port, all you need is a soldering iron and you imagination.

Here is a link to the Arduino website to give you an idea what I'm on about

Which one exactly have you got mate and how much was it? I looked on the site but they look quite expensive e.g. 25-50 euros or more.

Cheers

I use the Arduino mini, for small projects like Ho/oo house lights, for bigger products I will use the bigger versions, if you search eBay you will find them for a fraction of the cost of the genuine Arduino website or Maplins

Here is a link to a uk seller on eBay selling 5 with the sub control board for £12.99 so about £2.60 each http://www.ebay.co.uk/itm/5x-Arduino-compatible-Pro-Mini-5-Volt-ATMEGA328-5v-TESTED-UK-STOCK-/161805079939?hash=item25ac559583:g:Mk0AAOSwDNdV3HRY

Because Arduino have made the whole project open source, this means the Chinese can leagaly make and sell copies brining the cost tumbling down

This is something I might well look into myself. We've used arduinos in work to light mock up aircraft seats but I hadn't considered using them for modelling.

Daz The little Arduino's are cheap as chips and simple to program, the only limiting factor is your imagination.
