A new Thiiiiiiiing is being made. Stay tuned...

This Thiiiiiiiing is based on a motor and a Li-ion cell I bought in RC hobby store. The motor spins at 39kRPM (650 Hz), which is faster than regular Dremel's max of 30kRPM. It also has quite a bit of power. Not nearly as much as regular Dremel, but much more than the old Thiiiiiiiing.
