Remote Controlled Beer Crate

Advanced BBQ Accessory


“If you want to be successful on YouTube, you should build things like remote-controlled beer crates.“, Kati once said to me. Besides the tempting promise of viral online fame, I found that quite a funny idea! So last Saturday, I built one. Let’s see if Kati was right with her thesis!

Here’s the video (Caution: I also put “heavy metal” music on it, because I think that helps to support her postulation):

Materials list:

  • Beer crate
  • Competition pro joystick
  • Remote control toy car (only the RC electronics boards are needed)
  • Microcontroller (to interface between joystick and RC transmitter board)
  • 2 windscreen wiper motors
  • A bunch of relais and diodes (to interface between RC receiver board and motors)
  • Battery pack
  • Casters
  • Plywood
  • Digital voltmeter module

Finished project first: Above is the RC beer crate with controller.

The “remote controlled beer crate” is actually just a flat plywood platform on which standard sized beer crates can be placed. It is driven and steered by two windscreen wiper motors with direct attached casters. Two swivel casters in front stabilize the construction.

On its back, you can see the power switch on the left side and the digital voltmeter (for monitoring the charge of the battery) on the right side.

All the electronics are mounted below the platform: On the top leftt, you can see the 2-channel RC receiver board, which came from a cheap toy car. As the receiver can only drive small motors, it controls the big windscreen wiper motors via relais H-bridges. On the bottom of the picture is the LI-PO battery pack, which came from my neighbor’s broken RC helicopter.

Finally, the modified Competition Pro provides a nice retro arcade feeling when steering the beer crate. Its four direction switches are connected via a microcontroller to the RC transmitter board which is mounted inside the joystick.
