LOL what the everloving heck is this, it's the weirdest thing I've ever seen an IBM logo on. Spoilers: it's legit. I have it, it works, it does precisely what it says on the tin, and I love it.

Takeapart thread coming soon.

@jgeorge i have seen a claim that these were used in speed shooting competitions; the semi random timer was the starter alarm, so that the competitors could be gauged from an unpredictable start time.

Plausible(?) but unverified.

@madrabbit I saw that on reddit. Given the time-scale of this thing's randomness (10 min to 60+ min so far) it seems like it would be a completely unfeasible random start timer for any kind of competition.
@jgeorge @madrabbit At the same time, 7 minutes to an hour is a pretty broad time span for preventing excess tunnel vision. 7 minutes seems way too short. An hour seems a bit long. And why not have a standard timer set to the perfect interval for what you typically do? I hate annoying beeps, so I'm calling this a torture device.
