Welcome to Maple Engineering

This is a community for those who come up with creative ways to make maple syrup. You don't have to be designing and building homemade vacuum or RO systems to participate. Have you done something cool with your buckets and spiles? Tell us! Are you proud of your tubes and buckets? Show us! Have you built your own homemade gravity of pumped vacuum system? Show it off! Do you design, build, or install giant, gleaming, stainless steel maple syrup production systems? Tell us all about it! If you don't make maple syrup but love it on your pancakes of johnnycake and want to ask question, ask away. The people posting here love to talk about making and eating maple syrup.

Finding vacuum leaks for an old guy (lemmy.ca)

submitted 2 weeks ago by [email protected] to c/[email protected]

My father's in his mid 70s and his hearing isn't very good in the frequency range that would be useful for finding his vacuum leaks.

I was thinking about setting him up with a directional microphone and a pitch-shifter app to bring environmental sounds down a couple octaves so he can hear them. There are tons of Android/iPhone apps that will pitch-shift in post, but none of the trial/freemium ones seem to work on a realtime monitor stream, especially on an external USB (UAC) microphone. I don't want to start buying dozens of apps just to try them.

Any app suggestions or other ideas for him?

Thanks! Found a couple of much cheaper ultrasonic detectors that claim to do this, so we'll try those (and the spectrum analyzer) first. The usb mic looks great if those don't pan out!

I'd be totally interested to see how those work, what sensors did you grab?

We bought this AllSun adapter . It was able to confirm some smaller dropline leaks, but it missed more than it found. It was completely useless at finding the larger leaks (mostly in saddles and 3/4" tees) that seem to be the bulk of our problem.

So I'm pushing him to try the hearing aid apps -- this one is expensive, but seems to have a good combination of EQ and pitch shifting that may make it possible for him.
