Off topic: Havoc Heli, reminiscences
- Been lurking for a while. Have never seen Dr. Who (my loss, I guess)...
Wal-Mart has the Air Hogs Havoc Heli on for $29.99 CAD so bought one
for me and each of my sons. These little indoor helicopters are a
blast - run on pulsed IR rather than RC. The choppers weigh only a
few grams and contain the tiniest little pager-type motors and a bitty
3.7V LiPo battery! The copters are so light that they suffer little
damage when flying into walls etc but eventually they'll splat and
I've asked the boys to send me all the pieces...
Some time ago I mentioned a reset device consisting of a Nu+ and a Nv-
in series. We had the prototype hooked up for two weeks with no resets
and the IT manager finally said, "Just go ahead and build them."
Three days after I removed the prototype, the system had its first
error in at least four weeks. Ironic. Anyway, I am building them
into cases now.
I have been playing with digital timers (a project carried forward
from the mid 70s when building a house and having children somehow
interfered with hobbies for a while). My largest breadboard is covered
with clocks, counters, a flip-flop, 7-segment display drivers, and
some icky old surplus 7-seg displays (I got these from the old J & J
Electronics in Winnipeg and have had them for thirty years. I have
better ones but wanted to do this project with the old junk!)
Am collaborating with my middle son to redo his minesweeper for next
year's Western Canadian Robot Games. He has all the electronic/
computer/ programming/ sensor stuff worked out, but the mechanics on
his bot suck (his words) so I offered to make a new chassis and drive
system for him (I need projects for my new Sherline mill)....
Keep BEAMing and dreaming
- I've gone green with envy!
