thank you

this is brilliant. thank you for publishing this, I think I might have just found an economical way to buy myself a piano with a real action.

Glad you like it although it's in a very rough shape here. There's another more advanced project inspired by this one and I've linked to it on the main page too.

davidedelvento, excellent information. "way better than VPC1 or MP11" is the piece of information that I wanted to know (ideally from a piano player qualified to make such a statement). and thanks for taking the time to walk through the scenario that might be best suited for a beginner. I think what you wrote is correct. There is indeed a free yamaha baby grand being offered on craigslist. No space and too loud for neighbors, so I can't have it. I can definitely buy a used Privia or new VPC1 and call it a day and focus on learning, very true. But at the same time the diy controller seems to be excellent value and superior over the mp11 if I can get a cheap key bed since I can handle the electronics/programming and probably some regulation from referencing youtube videos, but nothing by ear since I am a beginner.

You are most welcome. Re: the Yamaha baby grand. Usually those are scams (the really free pianos tend to be the ones from obscure brands of more than 100y of age), but if it's not, you can take it, remove and keep the action, keyslip, keyboard cover (and possibly part of the case as I described IIRC here) and pay the disposal fee for the rest of the instrument (which will be around $300, all included). Similar to what I've done myself (but meanwhile I have two other pianos to practice on, until I finish working on this project). Best of luck and stay in touch here or at the https://github.com/jkominek/piano-conversion/

thanks for the links, didn't know about the forum posts. could be a scam, I've forgotten that craigslist is full of scammers.

Hello,

I am totally new here in Gitup - and I am curios, if someone is still reacting, since this project is a kind of old.

First of all - congratulation and thank you for sharing.
You mentioned another project, inspired by your own, but better, more advanced.

I did not find it.

Where can I find it?

I would be interested to see it. I want to transfer it from a grand piano to an upright piano. I hope it will work.

all the best to you

Steve
