What’s fun, cheap, good looking, and cleans a hardwood floor with an advanced search and navigation algorithm?
An electrostatic dust mop attached to a radio-controlled car. Vroom!
This combination has some things in common with a Roomba, but is arguably less expensive. It’s quick and fun to build, and quick and fun to operate.

Turn off that television in classic style!
Here we show you how to hack a TV-B-Gone into the case of a vintage television remote control, such that the original on/off button instead activates the TV-B-Gone. We also modify the power supply so that it runs off of a regular 9 V battery, instead of a set of lithium coin cells.

Mod a cheap radio control boat into an RC magnetohydrodynamic vehicle.
This design serves as proof of principle for modding an RC vehicle to run on MHD. Rather than being a performance design, it travels at an astonishing speed of several feet per minute since it uses essentially the same design as our foam-tray MHD boat.
Read on to find out how we made the conversion, what worked and what didn’t, and how we plan to get some speed in the next revision.
