arhi..
Really? It got through all those? hmmm...
I mean I have IR stuff all over the place in my home. I can change my TV from random places, my IR remote for my camera will usually work if I am not directly in the line of sight....and such..
I just want to be sure I won't have an issue with the resin before I go ahead with it. Basically I want to get your guys' expert opinions before I go out and buy anymore stuff. I just spent $180 on the RF materials only to find out it probably won't work....so I need to be sure the solution I choose to test is the best one.
Just so you have and idea everyone:
**broken link removed**
This is what the inner resin will look like...it will also include an outer shell of semi-opaque resin so you can't the inside....so it "looks" solid.
There is ALWAYS a deadline, else it must not be needed. You did say "movie" prop.
Is the resin going to be clear so you can see the insides? Are the batteries going to be replaceable or molded in? How large do you want it to be?
Seriously put a switch in it. Teach the actors how to use it, it's an illusion the audience won't care.
No, the deadline is my own. The batteries will be replaceable via a cap in the bottom that allows the core to come out so I can replace and service the electronics. Each device will be roughly 18 cm in diameter, and about 10 inches high.
I agree with you, the switch idea is the simplest way, but it's not what I am looking to do. I don't mean any offense or anything, but I know there are practical ways to do this and I have done many props that do such things, but for this one, I really am trying to do something different....for my own pleasure, and a learning experience.
I wonder whether RFID could be made to work. I think each device would need both a passive RFID tag and an active RFID reader, and I have no idea how small those are.
I thought of that....I have FOB (a thing for getting into my underground parking) and it basically does the thing I'm trying to do. It's super tiny and when I put it close to the pad by the entrance it "sees" it and lights a little LED, then opens the parking door. I can do that thing through my window on cold days...and it has about a foot range. I don't know anything about them though, nor could I find anything online to get me pointed in the right direction.
