Has anyone got one of these Kellogg's cycle computers to work? Quite literally giving them away with Cornflakes.
I got it for one of the kids bikes but when my battery finally failed in my computer today just before a ride I thought I would pop the new Kelloggs on and see how it performed.
After getting no reading at all I examined it a little more carefully. I discovered that the electrical contacts on the computer module seem to be made of rubber! These push against the metal contacts on the handlebar mount when it is slid into place.
Rubber is not generally accepted as being a great conductor of electricity so this probably explains why I was struggling to get a reading!
Has anyone else got one? The rubber is not a protective cover and they must have manufactured quite a few of these.

Materials that look and feel like rubber can be conductive. For example many computer keyboards use such stuff.

If you've ever taken a TV remote control apart you'll have seen that the buttons on the back of the keypad that short the contacts on the PCB are also made of rubber - this is 'magic' rubber and does a reasonable job of conducting electricity.
