μWWVB is a watch stand that automatically sets the time on atomic
wristwatches where regular WWVB signal isn’t available. The system
acquires the correct time via GPS and sets radio-controlled clocks by emulating
the amplitude-modulated WWVB time signal.

I recently had another chance to use a fancy algorithm to
solve a real-world problem. These opportunities don’t come up all that often,
but when they do, it’s pretty exciting!
Every year, MIT HKN has a bunch of eligible students who need to be
matched to committees. As part of the assignment process, the officers decide
how many spots are available on each committee, and then we have every eligible
rank the committees. In the past, officers matched people manually, looking at
the data and trying to give each person one of their 1st or 2nd choices.
Unfortunately, this is time-consuming and unlikely to result in an optimal
assignment if we’re trying to maximize overall happiness.

Gavel is an automated end-to-end expo judging system. We’ve used it to automate
judging at HackMIT, a 1000-person event with over 200 projects and
100 judges. Dozens of other events have also used Gavel since the software was
released in private beta in late 2015.
Gavel fully automates expo judging logistics and project ranking — the
system tells judges which projects to look at, collects judges’ votes, and
produces a ranking of projects.
Here’s a demo of the judge interface:
