I went through this idea a while back but the problem was how to overcome having a second switch for main power for the 555 circuit? If the circuit remains powered up all the time then the batteries will go dead so we are back to having two switches again. I haven't given up on the project it has just been shelved for awhile until I have time to devote to it. Good luck on your endevers though.

But aren't you going to have that problem anyhow even with a momentary switch for just the sound module? The 555 timer shouldn't drain that much, and if it's one shot, meaning only one pulse is sent, then the drain from the 555 circuit should not be enough to drain your batteries. Also, what's the amp rating on your batteries? If it was a wimpy one to start with, then yeah, of course it's not going to last long. Anyways, I'll build the circuit by this weekend and give it a try, then i'll post my findings, lookout for it.

The 555 timer draws around 15 ma in standby mode over a few day this is enough to drain the typical battery. Keep in mind we use AAA or AAA batteriers in our sabers which have an ok current rating but will not last that long with a steady drain. The sound board current draw is so little that it is hard to measure in standby mode so the batteries will last weeks in a hasbro sound board powered saber.
I was thinking about using a small socket with plug that could be used as a main power switch for the saber. One could take a plug and bridge the contacts on it then connect the jack as you would a switch then when the plug was inserted the cricuit would be closed and powered up, plug out powered off, You could make a knob to disguse the top of the plug and then build another plug assembly but without bridging the conacts and you would have something to put in the socket for display purposes.

Could I use a momentary switch from RadioShack for the SB, or do I have to use the switch that came with the SB in the first place?

listen to master do-clo, he is wise.

Just a thought and this may have been covered. What about using a relay for the inverter so that the momentary switch triggers the sound board and the relay that would supply 12v to the EL untill triggered again via the momentary? I think Do-Clo has explained the power split well enough so it really wouldn't be that big a deal. Being that you are using a 1.5 sink tube you have plenty of room you could even use a programable relay though they are not cheap.

I have always used Corby 86 programable relays for stuff like this. They have all kinds of cool things I have used these for and I think they are a bit cheaper.
