thanks Ivan! for DIY, analog is the way to go here...ADXL335 (analog) and analog IR sensor for reference and your PicoScope (or that HS402 WiFi Jim gave you that would allow you to do this from driver's seat, no wires) Martin and I are about 1 yr into a digital dynamic balancing kit. Serious stuff this one... Your interest in my channel sure has been a nice boost:)

the key to this is a clean sine wave...usually needs software filters oscilloscope filters typically "shift" the waveform as it cleans it...I suspect PICO filters would do this... @ 3000 RPM, it doesn't take much... in working closely with Martin, he developed filters that do not shift...a game changer for this work a recent development that has not found its way into the HScope "production" release...only in BETA at this time scrolling down the Google Play HScope page allows the option to join BETA a $3 ADXL335 powered by your 5v REF Box and analog IR powered by another 5v REF Box and HS402 WiFi and you'll be pleasantly surprised Ivan...

Did you notice any differences putting weights at the front if the shaft vs the rear? It is common to find a weight at each location of different grams and different positions. And when one is changed, does that affect the other? Or can this hose clamp method be done properly on one end of the shaft at a time and provide an overall benefit?
@theGADGETSplaylist

would be one end of the shaft then the other with accelerometer positioned near the end being measured... on long drive shafts, when one is changed would not much impact the other...

Denis, in this case does it matter which orientation the ADXL335 sits on the differential? I guess any vibration would transmit side to side as well as up and down so it shouldn't matter? I might have to balance a 3 piece driveshaft in the near future but wondering your thoughts on mounting the ADXL335 in the middle of the car lets say at a joint in the driveshaft. Would you just secure it somehow to the body of the car?
@theGADGETSplaylist
6 ай бұрын
for vibration analysis, orientation wouldn't matter...BUT for dynamic balancing orientation does matter...there is a "+G" and "-G" to the parasitic weight movement withing the accelerometer...I intend to do a video on that subject at some point in future... worse case scenario is being 180º off, you'd realize the mistake for that 3 piece driveshaft, I'd place the ADXL335 onto the center support itself and temporary correction weights first...confirm your work and then make the weights permanent good luck and let me know how you make out

I am speechless !! I've intently watched 'pro' dynamic tire balancing guys in action. Was never impressed. This takes all of the guess work out of the task, wheel or drive shaft. I'm fairly sure your 3 axis accelerometer can pick up ring and pinion or bearing vibration, yet I don't see it in the wave form. Did you tune it out or desensitize the circuit ? We are lucky to have you on KZitem Dennis !!! It's too long of a drive for me, but we owe you a beer !!! Please confirm the spelling of your name. I've seen it 2 different ways.

good method ,years ago we had trucks with 2 axles and a carrier bearing ,that would have worked good in diagnosing them. GM never had any training or repair methods then. either replace it or send to an axle shop that done balancing, so many of drivelines where replaced for that. we even filled some with expanding foam or fill with oil, i'm serious, seems like extended cab s-10's were the worst

This is amazing and i would love to try it, however, the bits all appear expensive and pieced together, i am overwhelmed by that. if they had an inexpensice kit with everything id be onboard. ive been through alot with this driveline vibration issue. using a hose clamp the caveman way is alot of fettling. drive it, adjust, try this/that, dozens of times vs that device..... i'll tell you what though..... I will bet you ten chickens and two pigs that the heavy spot is 99% of the time going to be where the runout is. If you put anything near the shaft almost touching and spin it slowly, you can see if its spinning true or if it is slightly out of round. a dial indicator is great too. and then the weight needed is the key. the head of a hose clamp is a bit heavy. 14 grams. My runout is .019" at the rear and almost zero up front. Ford specifies
