Remember the massager-cum-raygun?
I’ve been inspired to get to work on the interior of this device. I can always build onto it later, so the interior is on my mind.
My original idea is to have LEDs inside that shine through the air-holes in the front and rear of the device. As there is a lot of room in there once you take out the huge ancient motor, I was thinking it could have a rotating circle of white and yellow lights.
The specifics of how to make electronics that rotate are, though, perhaps beyond me. I don’t want to buy PCB-making equipment because I need a lead that rotates with the board (and besides, I think I’d have to leave it vulnerable to the elements, which sounds dangerous in a metal device). rbradakis mentions there are motors that have electronic connections that funnel through the turning mechanism, but I don’t know where I’d even begin with that.
Less impressive, but still interesting would be keeping the lights stationary and rotating colored gels above them. The color shift wouldn’t be gradual, sadly, but it’d be less expensive (requiring only two white LEDS instead of four or six, half being yellow). And no rotating electronics foofaraw.
So, with the assistance of LEDcalc and the advice of more electronically inclined friends, I think I can make it happen.
Now, I’m considering sound.
There may be enough room in this thing to also include a sound board or some sort. I’d like something that would work like those greeting cards you can record your voice onto – something I could make produce an ‘electronic sizzle’ sound that would repeat endlessly while the switch is on.
How to do this, though? So far, I’ve found a few related links (that last one being the best so far), but nothing that’s exactly what I’m looking for. I even have a disposable USB music player, if that would help.
Anyway, if any of you have any advice or directions I could look, I’d be grateful!
EDIT: Oooh. It’s somewhat heavy, maybe I could build a brace into it that attaches to my forearm with a leather strap.


Answering Mark’s prayers and bringing us all one step closer to looking like Geordi La Forge, Sony has unveiled eyeglasses that can show full-color video images. The prototype supports a QVGA resolution, weighs 120g, is 3mm thick at the lens, and has a contrast ratio of 50:1.
