B C Posted April 20, 2019 Report Share Posted April 20, 2019 For sale is a knock detection setup I made. It includes a BMW E36 (S52) knock sensor, amplifier, and ~10ft of cord to reach into the engine bay. simply bolt it in to a good place on the block, plug in some headphones, switch on the amplifier and listen to your pistons melt! $25 shipped/$20 picked up Jdesign 1 Quote Link to comment Share on other sites More sharing options...
GunMetalGrey Posted April 22, 2019 Report Share Posted April 22, 2019 @HipMF showed me his intense setup this weekend. This route seems much more logical! Jdesign 1 Quote Link to comment Share on other sites More sharing options...

Proof of concept! I wired a knock sensor up to a guitar practice amp which has a headphone jack. I haven't tried it on an engine yet, but I did spend about half an hour clamping the sensor to various things around the shop and tapping on them with screwdrivers and such. Actually worked even better than I thought it would, plus I have all the material I need to make my own ominous tones album. The only issue I had was when I plugged the amp into an outlet that wasn't grounded I got a lot of hum. How well did these work for you? This looks a lot more convenient than dragging around a practice amp and finding a place to plug it in... Jdesign and GunMetalGrey 2 Quote Link to comment Share on other sites More sharing options...
B C Posted April 22, 2019 Author Report Share Posted April 22, 2019 ha! Yes I ran around playing doctor/stethoscope dude with it. I did not actually mount it and run it while tuning but I have no doubt that it would work as expected. Jdesign 1 Quote Link to comment Share on other sites More sharing options...
The Full Banana Posted July 30, 2019 Report Share Posted July 30, 2019 Do you still have these? I have a new engine and lots of paranoia that these would help with. Jdesign 1 Quote Link to comment Share on other sites More sharing options...
