WHC 10: penta-vibrating grip redux!

posted Apr 22nd 2007, 01:06 under arduino, processing, vibration, WHC

After the quick success of the vibrating duet (WHC 7) it is now time to try out a full 5 nodes version. Actually this project is a direct revisit of one of my first mock-up, the penta-vibrating grip (WHC 2).

Much of this has already been done before, it is more a matter of redoing and repacking the various parts. One nice thing is that my sequencer application works very nicely with this grip (replacing the 5 pistons unit). The Arduino code stays the same also, only the actuator/vibrator relays need to change. For the records, we are now using the regular 4420 IC instead of the 4421 ones. The pistons required inverse signal (no input - output on), where the vibrator motors need direct (no input - output off).
