I was ruminating over one project in particular that he had built called the IRritator when it suddenly struck me, I bet he might have something that requires a remote control, like a TV (at least, I am hoping that he has a TV). Anyhow, assuming that he has a TV, I bet he has pressed the channel-up button thousands, if not tens-of-thousands, of times. That's a lot of effort being exerted to change the channel. But what if that effort was not necessary? What if there was a way to change the channel without ever exerting the effort it took to press the button? What if there was a machine that pressed the button for you once per minute? Well then, perhaps, just maybe, that would be The Most Useful Machine... EVER!
And thus, I have made janw The Most Useful Machine... EVER! for the Instructables Gift Exchange. If it turns out that he doesn't have a TV and this machine isn't as useful as I hoped it would be, then perhaps he can combine it with his IRritator and make the most annoying clock ever made. Towards this end, I have also mailed him the minute hand, so that should he need to, he can use it to trigger the IRritator for one minute every hour.
