Very cool! Thank you for the video!!
Thanks going to be building my own soon.
Great video! Was looking for this exact thing, cheap solution save 500$ :)
I had a small delay in sound getting to the headphones. Worth bearing in mind.
hi thanks for this video, much appreciated for beginner tuners like myself on a budget
should it be a 4 or 3 pole male jack(TRS Type Male Audio jack like the one you)? as shouldn't the knock sensor be a mic which will send signal to a 4 pole male jack to send knock signals? or do i have this wrong
thanks
I think it depends on the laptop you are using and the inputs it has. Try different jacks until you find one that works.
How to wire two sensors? Can they be merged into one wire?
I suppose its possible but how would you know which sensor has the most knock? It might also be too noisy in general.
@@DriveTuneMedia agree with you, noise could be the problem. Maybe going stereo, one channel per one sensor. I only care about hearing knock better not which cylinder it is in.
Sorry for replying to and old comment, but wanted to say this: You could hook up a 4-pole (Stereo) jack to a stereo 3.5mm jack, or a DAC (like a Behringer UCA222, with L/R RCA IN/OUT), then wire/record one knock sensor on the left channel and the other on the right channel. Also, if you need to record the audio data for analysis, you can record your input with Audacity (free wav editor) and you'll be able to see both inputs when your record.
