Here are some examples of the sorts of electronic projects that we have worked on in the past.

This is a MIDI instrument that we designed that has eighty-four pressure-sensitive keys. There is now a newer revision that has these keys plus a few other controls that give the instrument much more capability.
These are the receivers for one of the magicians' tools that we produce. It can drive two hobby servos. There is a newer version now that can detect the battery level and indicate if the battery is getting low.
This is the master control box for one of our projects. It houses six removable circuit boards inside.
This is a control panel for the same project. This panel allows the user to control the function of the device being controlled.
