Where can I find someone to create a custom sound effect board?

If you're looking for professionals to handle this, try finding local makerspaces or hackerspaces. They often have members who specialize in electronics and could help you with your project. Additionally, look for prototyping or industrial design firms in major cities that take on unique, one-off jobs.

Have you considered sound pad boards? There are ready-made options like the Launchpad Mini that might fit your needs. However, if you desire something vintage or more customized, finding someone on platforms for custom electronics would be the way to go!

If vintage is your goal, there are often vintage sound effect boxes available online. Websites like eBay might have what you're looking for in terms of a unique aesthetic. Just make sure to look for programmable options!

You might want to check out Tinkercad for prototyping your idea virtually. It’s user-friendly and can help you visualize your sound board before building it. After that, you can acquire basic components from Amazon to assemble the real thing. Just an idea!
