Juicy Spheres Snack - Easy Kitchen Science
Great instructible! Just a side note on the Tamiya connectors: the reason the hobby industry has strayed away from those is due to current issues. You may find, if you use the drill for an extended period of time, the connectors will get hot and can actually melt together. You might want to consider switching to an XT60 or XT90 connector. These are rated for a higher current draw/output. You can find them on ebay or Amazon for a few bucks a piece, but well worth the money.
