Strange request from a harmonica player - blower/drawer machine

Hello there,

So there it is ! As an admirer of DIY Perks I dare to post here for a special project I have in on my mind for the last 12 years.

Every now and then I need to dismantle my harmonicas to tune them, and this task is tedious since I need to screw and unscrew the reed plates for the blows and draws in order to tune the reeds.

So my idea would be a machine with a powerful reversible fan that can blows and draw (or 2 fans, 1 for each function), a electronic speed variator, a on/off button, and ideally being able to be powered via USB C or a 9V battery.

Could you recommend the best parts for this project and how to solder them ?

Thank you in advance,

Christelle

Are you able to specify how much air pressure you're likely to need Christelle?

I haven't played in decades and I was never very good.

You'll need centrifugal fans for this and such things do exist but I'd need a lot more detail to help.

Take everything I say with a pinch of salt, I might be wrong and it's a very *expensive* way to learn!
