Shock dyno (or Shock absorber dynamometer)

[tonyfoale]

hello tony, beautiful and interesting dyno. did you made the load cell? riders being riders one would be better off connecting a shock dyno to a crystal ball then to the "subject" brain (or whatever we have for one - rider part talking hehe). thanks for sharing. any pics of pistons, valving stacks, chambers you want to share?

Pete,

No I didn't make the load cell, that is an off the shelf item. The load cell itself is not overly expensive, but you need to have a decent instrument amp. as well. If I recall correctly the amp. was more expensive than one cell but I can use it for some other tasks which use other load cells. You can buy instrument amp. chips quite cheaply but you need filters etc. etc. I could have easily made an amp. but unless I got very lucky it would have required some development time which I would prefer to spend on developing the suspension.
I don't have many pix. of the valving of the stuff that I have been working on because it was always a work in progress. I'll see what I have though.
