Yes, this was built with a $9,800 grant from the Lemelson-MIT InvenTeam program:

This is a great program! If you have an urge to invent, you should take the lead, as our students did and encourage your mentors to sign on to the project. This year's grants were just announced but, there is a good amount of lead time to prepare for next year. Initial applications are normally due in May.
You can find a list of this year's grant recipients here:

Good Luck!
