you may find the following presentations in using ga144 entertaining, even if stretched. as Chuck Moore once said (I'm trying to get the ref) Forth is about sharing ideas rather than code. these videos are not pure coding session (even if they have their own share) but a mix of engineering and problem solving.
- echolocation like bats
- heart monitor
- digital image processing
- building ga144 controlled robot
- low speed usb host
