I really think that the screw in bulbs and easy to change switch covers are a big part of the illusion of this device, remember you are trying to involve someone else and their ability to understand the easy to exchange lamps and switch covers makes it all the more frustrating to figure out.

I looked around some on-line for similar lamp sockets but so far nothing that matched what they used. Search continues.

Those screw down lamp holders used to be really common, you might try sources for dolls houses?.

EDIT: Search for 'mes lamp holder', here's one source

Radio Shack has 'em.
I'd prefer leds for now, 3v0.

OK I will make it so you can use it with either LED or bulb.

Radio shack has
E10 Vertical-Mount Bulb Holder (4-Pack) $1.69 Model: 272-360 Catalog #: 272-360

I think you may be able to stuff these into holes drilled into the wood. They also have surface mount plastic bases which cost more.

Those are some ugly bulb holders. Would look good with knife switches

Screw in bulbs are a must. This gives you some time while trying to screw in the bulbs and BS..

Also they DO make LED lamps, tried to do a quick search for them with no luck. But they have a plastic white bulb.

Edit: I've seen them in battery powered candles. I do however think this would look better using huge bulbs that you can see the filament in them.

Been thinking that bright white LEDs that are fixed might work fine, just need removable colored lamp caps to switch around like the switch covers.

IMHO LEDs are too high tech and many would figure they contain some form of wizardry inside (like a flashing LED has)
Colored LED covers might work but it'll still appear modern.

I think knife switches would really add to the illusion.

Especially if they were hand made out of stained wood.

Actually it would, real antique looking.

I was thinking of using these inserted through a wood base thick enough to hide it, all you would see is a hole to screw the bulb in.

If anyone knows where to find porcelain lamp bases squeak up.

First cut of a schematic using 16F88.

Power with 4 cells.
To use with bulbs bypass resistors R10-13 with junpers JP1-4.

If you choose to use LEDs you need to polorize the sockets.

This should be easy to etch and solder.

EDIT: Current version is 1B which uses SMD Jumpers
Board is aprox 2.0 x 1.5 inches
Updated schematic
Added board and foil images 300dpi
Will post eagle files if requested

Marks256 · 20th January 2008, 11:41 PM

i know this might seem dumb to some of you, but if you cant find colored bulbs, this may work

it is how to stain glass with glue and food coloring.

it is a PDF file.

Oh. AND ONLY DO THIS WITH AN ADULT PRESENT!

The layout of REV 1A is done.
I will build a test board mid week.
See my previous post.

You're fast, I've begun wirting the code in assember.
Bet your students will love it.
