Altoids tin

Michael said:

Another reader posted re: using an Altoids tin for RF shielding. I found another use for them. My
el cheapo (less than US$10) Schwinn computer works well but it doesn't continuously *log* speed,
so I designed and built a logger using a microprocessor, some EEPROM (data storage that needs no
battery backup), and a 9v battery .... and everything fits in a round Altoids Tangerine Sours tin.
I filed out the center of the "O" in "Altoids" to make a window for an LED that flashes
once/second as long as the bike sheel is rotating (I like visual feedback). I bought a second
Schwinn computer to get the nice sensor/connector. Altoids tin clips onto the handlebars next to
the Schwinn computer. Works great. It has enough storage capacity to log each wheel rotation time
over a distance of nearly 90 miles. Data is downloaded to my PC after a ride, and the download
program computes instantaneous speeds and write them to a file for graphing. Total cost
(neglecting cost of Altoids), including battery: about US$17.

If you put magnets on eight spokes then you could log your continuous speed eight times per
rotation, of course your speed would register eight times higher.

Hah! I KNEW there was a simple way to make your bike 8 times faster!

You just mount one of those large industrial magnets on your handlebars, and then get a fishing pole
and duct tape that to your back, so it projects about 3 feet out in front of the bike. Then hang a
hunk of iron off that. This pulls the magnet on the handle bars forwards, theoretically increasing
your speed.

Just have to be careful the hunk of iron doesn't hit you in the forehead during steep up hills, or
high winds. That can be distracting. ;-)

Pure genius! Even better than the carrot on a stick for the donkey.

In fact, make it a simpler system: Duct tape the pole to the top tube (sloping top tubes make this
work better) and hang the magnet from the end of the pole. Of course, those with aluminum frames
(like myself) are SOL, but steel riders will have a perpetual motion free energy propulsion
system...and the law of conservation of energy be damned!

Hey, magnets and conservation of energy. Seriously now. It is possible, I believe, to construct a
set of magnets where one floats above the others indefinitely, with gravity holding it down. Hey,
for that matter, gravity and conservation of energy. Any given piece of matter has a certain amount
of gravity, and that gravity never runs out. How the hell does that work?

Wow. Hostess Golden Cup Cakes, about a week old, can sure cause me to ask some questions that I
don't usually ask. I generally just take that stuff for granted...

This wouldn't be another fine product from the "ACME" company, now would it? ;-}

I want the jet propelled unicycle. "which even the most unbalanced individual can ride with
ease." ;-)

ShelBroCo had a similar product at one time.

Sort of a lapsarian technophilic Amish look going there.
