Thank you for considering my general question, which I assure you is serious!

I want to build -- or have built -- a magnificent shoe that can convert taps (front of the shoe) into Morse code and transmits it (two taps of the heel) to a remote computer to then run a "define: " query in Google. Then, upon automatically receiving the definition translated back into Morse code, receive the code transmitted from the computer to a small vibrating unit inside the shoe, which will play out the definition in a series of Morse code vibrations. The one tap of the heel will be for 'spaces'.

What do you think? Is this achievable if I consult with a physical electrical engineer and a shoe-maker?

(the purpose is for a magic trick that I am working on)

    \$\begingroup\$ It's very feasible. Was that all you wanted to know? \$\endgroup\$ – Ignacio Vazquez-Abrams Jun 17 '13 at 15:51

    \$\begingroup\$ See the book "The Newtonian Casino", describing the use of a similar system to cheat at cards - over 20 years ago. Nowadays it might be possible to do it with a smartphone alone (already contains accelerometer, vibrator, radio communications, battery) \$\endgroup\$ – pjc50 Jun 17 '13 at 15:53

  • \$\begingroup\$ Thanks guys, that's all I wanted to know - If it was achievable. \$\endgroup\$ – SirCumference Jun 17 '13 at 16:00
  • \$\begingroup\$ Physical EEs (as opposed to imaginary ones) and magic tricks. This would actually be a fun project. "SirCumference": Heh. \$\endgroup\$ – Alfred Centauri Jun 18 '13 at 0:41

It would take a lot of engineering to make this work properly and effectively, and that won't be cheap, but the basic operation you describe should be achievable.


Magicians sure like hiding things in shoes! About a year ago I built a signal processor for a remote control switch hidden in a shoe for a magic trick. What you ask for is certainly possible, but as Olin said, be prepared for a big bill.

Google "Electronics for Magicians." If you don't already have that book, it's a nice introduction to building your own circuits for magic tricks/performances. It will give you some idea of what you are up against, hopefully.
