Indeed, the strain gauges on the avenue trucks work perfect. There's a lot more intrinsic dampening of the signal as a result of the natural springyness of the material so the noise spikes on rough surfaces aren't as high, but it's still way more than responsive for sensing the weight shift. And unlike the previous versions with the strain sensing on the hanger, we've had no problems at all with signal drift. The zero point seems to stay consistent withing +- 1lb everytime the board is turned on.Vanarian wrote:Hi Justin huge job done here ! Are the strain gauges responsive enough ? Keep going!
Will do!Ohbse wrote:Super keen for this! Please post as much gritty detail as possible

Actually, I think you're gonna become a full tester here! You'll hook up the load cell of the rowbike to the front weight sensor (the aux input), and for the rear weight sensor you'll hook up any kind of throttle or potentiometer device to control braking and regen. You can still have the ebrake input line on the brake levers, but you could also just have a thumb or twist throttle and when you turn that it simulates weight on the rear sensor causing the CA's output to go into increasing regen territory for variable braking control.rowbiker wrote: May I assume I have your permission to become a 'half' beta tester for this project?
Oh it's just the same circuitboard but stripped of the PAS pass thru signals and wiring pads to make it more compact. This way it folds over and sits right over the strain gauge and is then potted in a silicone protectionI'd love to see a schematic of the amp you're using on this version, since it's obviously different than the earlier "Strain4" board you developed
