The clever folks at NortHACKton have built an Arduino driven rocket launcher.
OK so it might not be a space program but it's a good example of practical electronics being used for something fun.
More details (including schematics) of the Arduino rocket launcher can be found here:

The uln2003a device has output clamp diodes for switching inductive loads, so no other diode should be necessary.

Nice work!
But I got a question: After checking their circuit, Why don't they use a protection didoe across the realy? How about bypass caps? What do you think guys?
