Hello Paco - it is a small world - remember me?
I was on the DataQ forum as well - was spoke on the forum about a dyno, (PJAdams user)
I also got a DataQ 148U - but also came to the conclusion it was not what was best. Also - I found mine to be somewhat unreliable. It kept 'freezing' and needed resetting.
I used the soundcard on the PC to sample inputs - and it worked (very well actually) - however - it was not accurate enough & PC timing 'wobbles'.
I found a simple Parallel data logger on the net (build it yourself) that samples up to 1Mhz - digital inputs only. That would of worked - but again - it is based on PC timing - which can 'wobble'.
I decided that timing is a critical element to correct work out (accurately) torque - and therefore it had to be an outside hardware timer - hence the PIC route.
I'm not an electronics guy & I'm struggling - but I'm going to order the PICKit2 & see where it leads me.
Regards
Paul (PJ Adams)
