Model Railway Electronic Project - Camp Fire simulator - Under construction - Dec 2017
All the Model Railway Electronic Project web pages are a work in progress at the moment, so they may ramble a bit or be a bit disorganised while I refine the various pages. Most of these projects were done quite some years ago without much documentation, so I'm in the process of documenting them, which may take a little while. In the mean time, what I have is being put up here. This is a little circuit that can be used to simulate a campfire or any other type of simulated fire. It uses red, yellow and orange LEDS, which, along with the adjustment pot on the pcb, can simulate anything from the glowing embers of a fire to a roaring camp fire by changing the rate of flicker.
I have designed a 'Universal' pcb that can be used for several different projects (that is why the 'Not fitted' references in the schematic above), but have not yet made one to make sure there are no problems with it. In the meantime, below is a preview of the pcb.
To do: Expand this webpage with more info. Make a small diorama and video it to show how it operates. More as I think of it.
