Hello All,
Don't know if my post about putting a bike speedometer in a car
went thru the other day but here is what I found out.
Me being sick of not knowing exactly how fast I was going or what time
it is. 110 indicated MPH is a little bit ridiculous. For a long time MC
riders have been using wired bike comp. to tell them the speed. (and time)
I went by a bike shop yesterday and looked at the selection. I ahve
a specialized wireless on my bicycle and really like it. But I know that you
can not use wireless on a MC or car (too much interference). There are a lot
of models some expensive +50 bucks with lots of features that you don't
need on a car.. heart monitor, cadence, etc. The best, and cheapest models are
made by a company called Sigma. I bought two of there low end models. It
indicates speed up to 184MPH with an accuracy of .1 MPH. It has a tripmeter
and a clock..Its a small black rounded rectangle about 2 by 1.5 inches.. It
only cost 12.99.
It measures speed by sensing the field of a magnet that you attach to
a wheel. You program in your circumfrence and it calculates the speed from
there. So, I guess as long as your circumfrence does not change much the
reading will be accurate.
Now I jsut gotta find a place to mount it. The tolerances between the
magnet and the sender are very small. ~5mm. I need to mount it somewhere
where that can happen and somewhere that will not get very hot. Any
suggestions?? I will have to lengthen the wire from the sender to the
computer but hopefully enough signal will get thru.
