I cannot fit a stock Beetle speedo to the instrument panel that is in my current buggy build.
I need a small speedo about 100mm in diameter which runs off the stock Beetle speedo cable with a gizmo that fits to the end of the cable and sends an electrical/electronic read out to the speedo.
The speedo needs to be pedestal mounted and weather proof.
I'm sure that parts are available to do this. I'm thinking of motorcycle speedos.
I'm sure that this has been done before.
Can anyone help me with a few ideas of what works or even might work?
I don't want to go GPS unless there is no reasonably priced alternative.

Re: Mechanical to electronic speedo
Vdo makes an adaptor to go from the standard vw cable to a hall effect sensor output like most speedos use.
It will all be ok in the end.. if is not ok its not the end!
Re: Mechanical to electronic speedo
Thanks.
Today I learned that there is an effect called the Hall Effect. New information. I have yet to understand any explanation so far. Electronics is a complete mystery to me.
I'll check VDO and see what can be done.
Thanks again

Re: Mechanical to electronic speedo
When I was fitting the Subaru engine to the Manx SR I needed to fit a small mechanism to the end of the speedo cable at the input to the speedo. It was connected to the computer. Without it the engine could not read the cars speed.
Was that a Hall Effect signal generator? If so, is that what I need?

Re: Mechanical to electronic speedo
You can buy a VDO signal generator that fits onto your speedo cable. Not sure of the part number, but Toddy knows it
Re: Mechanical to electronic speedo
Sorry for the late reply (havn't logged on for a while) the part you are after is a VDO 412.009. Goes on the end of a conventional VW (or other) speedo cable and puts out 5 pulses per wheel rev.
