Rainbow LED Roulette Beer Tray

The idea started with the new start-up of my water polo team. This was a friends team that started again with a water polo team at the bottom of the league. Everyone could play polo just fine, but we had no uniform or logo. I made this one up and also this beer tray.

It's a big hit in the pub when you arrive with this. I have now made 5 for different teams.

Now it's time to share it with everyone. Have fun making it and that especially while enjoying a beer.

What do we need:
-a good humor

-a beer on the side

-1x Arduino nano

-1x power bank (small)

-1x USB cable 0.3mtr

-0.5mtr Wire 0.14mm2

-1x Arcade Button

-2x M3x35 bolts

-2x M3 threaded nut

-5x M16x40 Bolt

-Plywood 500x500x10mm

-plexiglass 500x500x10mm

-1 x Switch

-0.5mtr x WS2812 LEDstrip

Tools: -lasercutter

-3D printer

-Soldering Iron

Op thingiverse staan alle file om de lasersnijder en 3d printer aan te zetten.

It's all pretty easy to make:

1 - let the laser cutter do its job with the plexiglass and plywood

2 - Putting 3D printer to work over night. Saves time!!!

3 - Programming the arduino. (Program is in the next step.)

4 - Soldering the wiring according to scheme.

Cut the outside of the Usb Cable. Then cut the red wire. Solder the cutted ends to the switch.

5 - put everything together

6 - Testing everyting

Have fun with your friends.

BEWARE: this can lead to work if your friends want one too
