It is six for our drive ;D
They're all working great... someone really, really destroyed one of them when they were putting it on. The disk was completely destroyed and it didn't read (at all!) So we're going to need to order another... siigh...
We should be getting our AndyMark stuff monday (finally!) so we can put together our drive train
Hopefully it will be driving by Tuesday...
As for calibrating the encoders... it's a fairly straight forward thing. Hook each signal to a channel on a oscilliscope and move the encoder until the square waves are offset from eachother correctly, bolt it down and check it again...

We have built two of the encoders and divider cards. We have also have came across two hurdles to getting them working.
1.) How will we get the divider cards powered without supplying batteries?
2.) How will we get the male ports on the divider cards connected to the male ports on our RC?

To power them you need batteries... I don't know how else to supply power to a electrical device? Run 12v from the battery to the encoder divider power slots. This also powers the encoder itself. Hook the encoders to the encoder divider board as marked.
To connect the divider board to the RC, use a PWM cable
Good luck,
Dave
