World's Most Useless Machine by billybob884 World's Most Useless Machine by billybob884
Unfortunately, dA is apparently too snobby to allow just anyone to upload videos, so here are some stills of the machine; head on over to YouTube to see it in action!

~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~

This was a fun little project I did this weekend. It's the worlds most useless machine! You turn it on, annnnd.....it turns itself off! That's it!

Note: This is NOT my design, I got the original schematics from SaskView on Instructables.

It cost about $20 in electronics + shipping from Digi-Key (I used the 555 timer method, which is more expensive but you don't have to take apart the motor this way), plus a little $3 wood box I got from a local craft store (it's about 6.5" (16.5cm) x 4.5" (11cm) x 4.5" (11cm). Took about a day to do, did all the soldering by hand and glued everything in place with epoxy.

As soon as I can find something I like, I plan on changing out the wooden arm with a finger or something. I'm gonna try checking a few costume shops to see what I can find. What would really be great is if I can find something like an ape costume glove and use one of its fingers and fill it with some kind of foam to solidify it... we'll see what happens.

I will say this, it is a bit noisy, mostly due to the motor, but also partially because the wooden arm slaps the inside of the lid when it comes out to hit the switch. It will probably be a good bit quieter when I get a rubber finger to replace it.

The nicest part is it actually turns itself completely off once the arm fully retracts. There's no other switch you have to hit (the arm does this for you internally), so it doesn't waste power waiting for you to flip the switch.

That's extremely funny. :lol:

You could make it so one machine actually turns a second machine on and itself off. Then the second turns the first on and itself off again.

It would be cool if there was a non-electric version, only wood/nails/hinges. I can't think of a way to make that work, but if I could then I'd build one.

When you ever change the wood arm for an actual finger, don't forget to show us!

This would make a great self-destruct switch, you flip the switch and the arm comes out and has a flag on it that says, "Stop that!" turning it off of course before going back into the box.

You can also see it on The Colbert Report (6/8) on Comedy Central's website. I think it's awesome that you made one.
