Sad Ok Happy Fantastic Button Box

thingiverse

You know those devices at airports and other places that ask for your feedback? I wanted a device like that to let people capture their mood at work. It's not shown in the pictures, but it's powered by a Wi-Fi connected NodeMCU v2 that sends button presses via HTTP to a dashboard. The screws used on the bottom are 4mm wood/plastic screws. The buttons are 30mm arcade-style push-buttons. I managed to remove the top part of the buttons to insert pictures of emojis, making them more suited for this application. And yes, blue is supposed to be fantastic, heavenly actually. Not sad. The LED holder was an afterthought and I just superglued it to the inside. I opted not to add a hole for the cable in the design, so I made my own with my soldering iron once I had added the electronics.
