Operation Project background

[Dan Shookowsky]

I saw that Hive76 did a large-scale Operation game.  I was thinking of doing something similar, but with a Rudolph theme for Christmas (remove stockings, candy canes, etc).  I didin't see a full write up on the wiki.  What did you use for the conductive edge?  Foil tape?  Aluminum foil?  something else?

It seems like a pretty simple circuit with some power, a light/buzzer, and then a switch formed by the tweezers and contact with the "body", but any lessons learned would be appreciated.

John 'VoltWhiz' Siemiarowski did a lot of help on the project, and almost all of the electrical work. I'm sure he would probably be glad to help again if it's a civic minded project.

IIRC, we just used foil and hotmelt for the metal edges. The tweezers were slices of a street-sign, cut and rounded on a router, and using a section of 3'(ish) plastic pipe, and a plastic pipe cap. The internal electricals was 12v IIRC (from a generic wall-wart)  and we had some real back and forth with The Franklin to explain it was not dangerous in any way.

The nose is just a 'marine lamp' (from online) and we painted the inside of the glass shell with some cheap stain-glass stain from the local craft store.  The body was 1" ply top, sides, and bottom. We used foamcore boxes larger than the holes around the objects, to create the red background.

Oh, and lots of paint.

All told, it was 3-4 weekends of 6 hour days, by 5ish people each day.

hack on,

I thought the edges were lined with copper foil tape.

It was aluminum foil tape that we picked up at home depot. Worked quite well, too.

ducting tape is probably what peejay is talking about. Should save you some time of walking the Aisles of Home Depot.

Yeah, this stuff: http://m.homedepot.com/Paint-Adhesives-Tape/h_d1/N-5yc1vZ1xhmZarpz/R-100030120/h_d2/ProductDisplay?catalogId=10053&langId=-1&storeId=10051

Thanks for the feedback everyone.  That gives me a lot to work with.
