Thank you Gervase! Hopefully I'll be able to edit the next couple of episodes soon. I'm really happy with how it turned out and I can't wait to share it.
I downloaded a tone generator app on my phone and connected to a speaker I placed underneath the violin plate. I could do a frequency sweep to see where about the frequency was and then dial it in by hand. A bluetooth speaker should work. The most important thing is the proper placement of the speaker and the foam supports along the nodes/antinodes.
It's been 2 weeks since you've posted this video, Eric. I know editing takes time, but how long do you think the next few episodes would be out? The project has been finished for a really long time, I can't wait till we see the end result!
And will you play games and upload regularly again? I was a really big fan of the Binding of Isaac series, I think it was very cool when you played that game
You're right! It's american cherry, it has a lot of similar properties to maple although is a softer hardwood. This is why the tuning step is so important, I can't just follow a traditional thickness map when I'm using a different material.
How many watts is the speaker you use? I tried to achieve this kind of patterns, by the speaker of my stereo (20W) but there was no exact patterns. I couldn't find also a clear frequency to decide what is the 2. and 5. semitones of my plate.
I don't know the wattage of my speakers but I would imagine 20W should be more than enough. I've seen people make it work with small bluetooth speakers. The most important thing is supporting the plates with small foam standoffs at the nodes of the mode you're trying to find and placing the speaker directly under the antinode. I found that even if I was just a little off it would have a huge effect on whether or not I could see the pattern. Of course, that can turn into a guessing game if your plate is a off from the expected pattern you might have to move the foam supports and/or the speaker around a little bit, although you shouldn't have to wander too far. It might also help your search for the nodes and antinodes if you try and hold it by where you think the nodes are, and tap it where you think the antinode is. The closer you are to the correct spot, the more pure and loud the tone of that mode should be. As for the exact frequencies of the plates, I think the most important thing is that mode 5 is an octave above mode 2, and between the plates they should be about the same. Mode 5 can be a semitone apart between the plates which might change the color of the instrument. They should also be somewhere on the musical scale. My top plate had a mode 5 of 362Hz(F#) and a mode 2 of 175(F). My back had a mode 5 of 341Hz(almost an F) and a mode 2 of 170Hz(almost an F). The link below I found very helpful with this.

Hi there very few violin makers use cherry wood for one its denser than maple or sycamore and its resinous meaning if it's not dried properly it leaves damp patches when working on the wood this happens to mahogany wood also .The density of the wood to the age is also important and tuning the plates is another you need equipment for it and Chladni is a Polish version of Hladny which is Ukrainian. There's nothing wrong with Cherry wood only like mahogany its porous grain and a sod to carve I know.
Yes, the cherry has been interesting and difficult to work with. I had some on hand so that's why I used it. It has been drying for decades. I got it from my father who bought it from someone who got it from their father who originally milled the boards. In total it has probably been 30 years.
yet another masterpiece. i expected nothing less
Thanks for keeping up with the series, Lizzie!
Cherry back. Nice.
Yes.. I am enjoying this series and really like this episode. It's a cliffhanger.. I gotta hear what it being played!

I enjoyed the violin plate palm readings
May I ask what’s the meter or gadget you used to achieve the right frequency. Trying to learn any help will be much appreciated Thanks
Tone generator, you can download an app or you can find then here in youtube, hope this helps

Which wood are you using for back?? It doesn't seem like maple??

You do nice work, but dang bro, that gouge is dull. Chisel is better, but not enough. Bevel down is fine for that job.
