Hi all,
I designed an electronic instruments kits several years back using a set of Autometer gauges
http://coloradonortonworks.com/part-cat ... /#post-309
As a speed sensor trigger I made a stainless (non magnetic) nut that replaces the reverse threaded retainer that sits under the original speedo gear box. I had two buried magnetic pins inside that nut that were the actual triggers for the speed sensor. Nice and clean
However, over time I got some feedback from customers that told me that their speedos bounced a bit when they got up to higher speeds.
No liking this as the idea of having an electronic instrument is to have a more accurate gauge of course. So I decided to get to the bottom of it and just finished a new design on that nut. This has 6 triggers rather than two and instead of buried they are surface mounted. They are also larger in diameter.
This changes the frequency and also offers a more accurate trigger and stable signal. Ultimately this is making a big difference in the gauge. Absolutely rock solid needle all the way through the range. I tested on several different machines and all with the same positive results
So anyone that has bought my electronic instruments in the past and has bouncing issues (or not) can contact me at the shop directly ( nortonworks@fone.net ) so that I can send them a new trigger nut to replace the old style. It will require a re-calibrate of the gauge but that is very straight forward
