That is what I'm using !



@ FML very nice tunnel gun :yh: a couple years ago I made a simmilar device but no motor or battery it worked on tap tap and so it was much smaller and slipped on and off the end of a pen laser. in place of the motor was a skinny 1" long coil spring if you get the right length it sets up a harmonic when you tap it lightly and the tunnel can take on some wonderfull shapes, BTW they are never a true round shape some time they go through round but they are alwaws moving and changing there shape... I have one mirror right now that dose that and it is on a motor shaft, very cool effect I will try to get videos.

But how small can you go?

I was looking at pager/cell phone vibrating motors on ebay a couple of weeks ago and noticed there seemed to be a lot of different sizes on ebay. This ebay seller claims there motors are .3" long or <8mm wtf? Is this even feasable for a tunnel gun/ spiro? I saw some 23mm motors,

Pager and Cell Phone Vibrating Micro Motor - .5 to 3VDC - eBay (item 330347012155 end time Feb-18-10 19:09:05 PST)

This one is .4" long:

Pager and Cell Phone Vibrating Micro Motor - .5 to 3VDC - eBay (item 390073186033 end time Feb-18-10 19:12:15 PST)

Now all you need are some very, very tiny FS mirrors to go with it!

Edit: I would love to see you smush a spiro into your WhiteFusion build!
