Most of my electrical knowledge comes from high school physics and from osmosing things from electrical engineers when I hang out with them, but I think all you need to drop the voltage for the LED is a resistor.


Yup. In fact, if you order LEDs off of ebay from Hong Kong or China sellers they will often provide you with the resistors as well.

@limbolance,
As far as hooking them to wires... well, in my mind, there are too large a benefit to using batteries and making the piece truly modular that I would never hardwire the pieces up.

I briefly considered making some pieces that were battery powered but could be wired to each other anyway, either for more power or for communications. I don't think I could fit all the parts I would need in a 2x2 piece, but maybe someday I'll experiment with some larger pieces (resin caverns, maybe?).

More on topic, this mod continues to be amazing. My wallet is somewhat fearful of the day you start selling these. Any guess what you'll charge?

I am looking at using the 12volt wiring systems used in miniature doll houses - what voltage do the tea lights you used require?

All LEDs you will find for miniature work will require 3-5V to function. You need to use a resistor if using a 12V power source. If you buy a LED already wired up then look for one rated for 12V as it will then have the proper resistor wired in.

Very nice. I've done a lot of work on torches as well. They are the fun part. The magnets give me a lot of ideas. I'm struggling finding small enough battery holders. Currently I'm using CR2032 batteries, as they are thin enough to easily fit under the tile, but they are wide and I have to grind out a big enough space for them. I'm finding tea lights to be the best source for cannibalizing switches.

My question is, what batteries do you typically use in your projects and where do you find battery holders for them? I'm looking for much smaller batteries then CR2032

Thanks

Thanks for the compliment, Runeweaver. I am using CR2032's as well, but I have also found that you can use two AG3's which are also referred to as LR41 or SR41. They output 1.5V each so you need two for 3V. I have had to make custom holders for them, which can be done with resin casting or using styrene tubes and sheets, etc.

Good information on the batteries. I was just now able to pick up 100 of the LR41 batteries for $7 USD. Not a bad price. I'll see what I can do with them. Much appreciated.
