Homemade first look pulse sensor

Finally made my own. Used an enclosed piezo disc off amazon and glued it into the bottom of a threaded 3/4 pvc. Put a cap on the other end with a fitting screwed in. Just need to add banana ends to the wires

Captures from my charger. First one is vacuum, 2nd is exhaust, 3rd is exhaust with a misfire. I only brought home one lead so I couldnt add a sync to try to analyze the misfire.

We can't see your photos
Photo bucket no longer lets you share images unless you pay them for thrid party sharing. --- not cheap. To upload pictures to this form just drag and drop jpeg pictures into the are at the bottom of the screen then click insert.

Alternatively you could use Google Photos

Congrats! Would love to see those captures with a sync when you can. Were these taken during cranking? Running?

fixed the pictures. Thanks Andy
