Instruments and Hoverd-Palm Dash

While waiting for the brake disks and other parts to arrive, I've been trying get on with some other useful stuff. First on the list was finalising the installation of the bike clocks on the steering column. This took a while, but now gives me a nice clear view of the instruments without them smacking into my knees when turning corners.

For my secondary instruments including oil and water temp, oil pressure, lap timing, run time, GPS speed and gear indication. I'm using a nifty piece of software that Tim Hoverd has written for a palm. It relies on the serial output stream from my DL1 data logger. Tim and I often compare logs from our races so i took the opportunity to relocate my sensor inputs to match his to make this easier. Eventually I got it working for oil pressure, but water & oil temps and RPM still seem to be eluding me. I'm getting no RPM feed at all, and water and oil temps are both 300+ degrees at Idle which seems a bit exessive. So I'll need to sort that out ASAP.


Also today I did a bunch of other little wiring jobs including sorting out the neutral light indicator, the fan control circuit and so on.



All that's left on wiring now is a 12v switched supply to tell the DL1 where the start finish line is so that it can do the lap timing. A bigger still LED cluster for oil pressure warning and to fit and route the serial cable for the palm.
