Musical MIDI shoes feasibility

so I'm making a pair of Musical MIDI shoes. following the project guide for them from Thobson on instructables. Since I don't have the budget to buy the jacks or cords was thinking about salvaging jacks from old cd roms/computers that are lying around. Then for the cords was thinking about using headphones from the dollar store. did a test run to see if I could turn on a light with one jack and 1 headphone cord but didn't seem to work. so I'm asking is it feasible to do this? or what am I doing wrong?

Instructables is notoriously crap, if you want specific help then post the link to it.

k well reason why i didn't is cause most forums I've been on disallow link. anyway http://www.instructables.com/id/Musical-MIDI-Shoes/#step1 is the link

so I'm asking is it feasible to do this?

No I can see it I can say yes this is feasible.

This means you have made an mistake somewhere. So:-

  1. Post the code you used and use the code tags ( see stick post at start of programming questions )
  2. Give a schematic of exactly how you wired it up.
  3. Say what you expect the code to do and say what it actually did.

Not here they don't.
