One of the things that a lot of magicians use are magic tricks that use electronics. They are fun and you can do a lot of really impossible things with them, but the hard part is finding an “out” if the electronics fail. And they will fail at some point if you are out there working.
In my show I use a Rubik’s Cube that a special something inside and if that ever fails, in most routines you’re really screwed. Awhile ago I 3D printed a box for it, so if it does fail, I can use the box like the old color vision box. The color vision trick is a pretty good trick on it’s own, so having that as my back up method isn’t the worst out in the world.
I’ve been using the 3d printed box for a little over a year and wore it out!
I think a combination of me working outside a lot in the heat and it just getting banged around during travel shortened the box’s life. Luckily with 3d printing, it’s a very quick and easy fix. I just hit a couple of buttons and I had a new one with virtually no effort on my part!
