Sony’s KOOV robot construction system is designed to teach kids basic robotic concepts. The colorful blocks snap together, and can be programmed using a graphical interface which runs on tablets and PCs. Modules include buzzers, sensors, and actuators.
Electronic musicians and anyone who needs to combine audio signals will dig Bastl’s miniature mixer which provides five individual channels with up to 20dB gain each in a tiny box that runs on 4 AA batteries. It’s limited only to mono signals, but it’s still a nifty gadget. DUDE!
