@@phillipwombacher9635 was thinking along similar lines...have paroxysmal AFib, RBBB,PVCs, Wide Qrs and have hit bradycardia and tachycardia rhythms. I know, it sounds like the whole catalog. Being able to record events for my cardiologist would be a big boon., along with my Kardia 6L traces. Would love to see video of your project.
If you look around places like digikey or RS components you'll find an assortment of condenser mic capsules for very cheap. they're what's used in things like radio fist mics and I think they come in all shapes and sizes but round is probably the most common so find a diameter that fits the ID of your tubing and you can probably minimise the tubing to almost nothing and not have to mess around adapting sizes. I bought a bunch to replace one in one of my ham radio mics because the one from the manufacturer had an issue with RF feedback and I think that was maybe 6mm or 1/4 inch I can't remeber but very close to your smallest pipe there so you could easily get away with 1/4 inch of tubing between the scope barb fitting and the mic. They might not be super high fidelity but they'll be fine at the frequencies you're concerned with when using a stethoscope they'd do the job without spoiling a nice lav mic and they're only a couple of dollars shipped
Found the video by happy accident. The name "Loftus" at the beginning caught my eye. We see him often on Gutfeld. But, I'm afraid my warranty is voided from reading your all-inclusive disclaimer. I enjoyed the disclaimer more than the video ONLY because I was searching for instructions on converting an old medical stethoscope to a mechanic's type. Keep it up. We think Loftus is very funny and a smart guy. It seems his associates are too! Thanks, Chris I may watch it again to pad that TH-cam value to a massive 2/1000 cents.
Which microphone do you use (13:10)? I too had started to do a similar idea with that stethoscope piece. But one question the top hole of the 'oscultator what is it for (can you close it or not)? Thank you very much.
I have no idea the model of mic in that one. But the next time I have it in my hand I'll see if I can figure it out. It was just an old mic that had been laying in the drawer for years. It's very likely 90s, or even 80s vintage.
I tried using a contact mic for checking my blood pressure with a manual cuff, and it just didn't work at all. So having a small diaphram/coil type of sensor, which can detect the tiny bumps of air through the tubing seems to be the smartest.
Can you soften the tubing with a heat gun to get a better seal? Oh and AWWWW!! PUPPIES!!! Please give the puppies a fuss from me, they look like Gud Bois!!!
Yeah, heat and a bit of wedging works great with vinyl tubing. A poor-man's PEX expander is a pair of needle-nose pliers. Stuff 'em in the warmed up tube, pull the handles apart, stuff some more, rinse and repeat. Vinyl responds very well to heat, unlike PEX.
I did something similar in my review of my stethoscope. I just shoved a lavelier mic into one eartip lol. Great video as always! Heres a short example: th-cam.com/users/shortsRx9S_TQmEmQ
Metric tubing is specified in OD mostly, along with wall thickness.
I’m a nurse and you gave me a great idea I’m gonna hook this set up to a raspberry pi 5 and put a simple AI on it to listen for arrhythmias!

I love it when a plan comes together.
The dynamic lav mic looks like a Shure SM11

Hi Chris! Did you finish the project? could you upload a recording from the sealed Shure WL93-prototype, so that we can listen to a potential result?
I absolutely love your teaching style. You inspire me to do the same, or similar in my own style.
Thank you, kind sir.
And dog love!
Thank you :) and please give your puppy a hug for me :)

can u pls list out the materials needed? i need for my research, thank you!
Hot glue could be a good option for video, might be quicker and less messy than the epoxy.
And less permanent with alcohol removal.
Chris bio interface projects, robot arm prosthetic interface supper low signals
we on rhe same wave fr need ta link stg
Seven words that make algorithms love You.
Good job

Awsome! 👍🏻 😎
