I bought all the parts from your site to build this product 3 years ago.....I just opening up the box tonight and started build it. :) Better late than never

[@JakeMcIvor]

This would be a cool addition to an adapted music setup.

[@Graham_Wideman]

0:25 "four DC inputs". Why does it need 4 DC inputs? I'm pretty sure the plugs being discussed here are the four _outputs_ to the solenoids.

[@jordanclarke2996]

Yep lost me 0.25 in

[@gbruce8749]

Impressive 👍👏

[@Muiota]

Cool. I have similar project but on jumbos (automated midi drum set)

What kind of tool do you use to cut the aluminum extrusion? Thank you so much for sharing this, I'm going to build it this summer with my kid.

[@animisticbeliefs7644]

What’s the fastest these can play? What’s the highest BPM it can play 1/16 notes at?

[@Maycauseblindness]

Could this be expanded to 9 outputs with a second chip and more solenoids

[@alpkankirayoglu9153]

Where can I find the source to 3d print the mallet holder and base? Thank you.
