bike computer input - another newbie ;)
Archiver
Posts: 46,084
Hello Everyone!
Another Stamp (Microprocessor) Newbie here! I would like to make a
bike computer to determine real-time speed and the accumalated
duration of a riding session.
for the input device I think a magnetic reed switch is a commonly
used to create a pulse for each revolution of of the wheel. Using a
26" wheel and limiting the top speed to 50 MPH (I'm an optimist) the
max pulses per second should be about 19.
I'm interested in hearing what are other sensing options (maybe Hall
effect?) are commonly used and any pulse conditioning may be needed
for this type of application.
Thanks in Advance
Steve Blary

this, you might want to consider buying one of these:
http://www.rei.com/online/store/ProductDisplay?
storeId=8001&catalogId=40000008001&productId=47661372&parent_category_
rn=22000182
I bought a couple and I use them for anemeometers. I was halfway
through writing the pbasic code to calculate windspeed when I thought
of using these. They can be calibrated for a huge range of wheel
diameters, from several feet in diameter to just a few inches (like
in the case of my anemeometer wind cups). They also compute the
total distance traveled, max speed, etc. And for $12, that's a
pretty good bargain.

By the way, they have a few other models on clearance at that store,
each with slightly different features.

around somewhere but no control unit!
Would be a great solution but I would need some way to interface the
results to the stamp so I could use the data to make processing
decisions (the speed and time are not the end results)
Thanks for the idea! Now to dig up that old anemeometer in time for
hurricane season!
THANKS

Before you spend too much time and money using a basic stamp to do
this, you might want to consider buying one of these:
http://www.rei.com/online/store/ProductDisplay?

rn=22000182
I bought a couple and I use them for anemeometers. I was halfway
through writing the pbasic code to calculate windspeed when I thought
of using these. They can be calibrated for a huge range of wheel
diameters, from several feet in diameter to just a few inches (like
in the case of my anemeometer wind cups). They also compute the
total distance traveled, max speed, etc. And for $12, that's a

"Counting pulses from a bicycle speed sensor". It was an interesting
thread that really morphed into a discussion of energy expended by
hamsters on a running wheel.
