3D Printed Gameboy and Remote Controller with tinyK20 Board

As a remote controller for the Sumo robot (see “Zumo Robot with Magnetic Encoders“) we have used so far a combination of NXP FRDM-KL25Z board and a Joystick Shield (see “Joystick Shield with nRF24L01 driving a Zumo Robot“). That solution was not ideal, so this weekend I created a 3D printed prototype:

The concept is using the following parts:

For the push buttons I’m using the microcontroller internal pull-ups. The LCD uses a connector to the front board:

To LiPo battery gets charged from the 5V tinyK20 USB port. A 3.3V step-up/step-down converter supplies the 3.3V to the tinyK20 board from VBat:

All the components fit into the 3D printed enclosure:

The external debug circuit (to use the tinyK20 as debugger) is removed to shrink the box size:

Summary

With this project I have handy remote controller unit with nRF24L01+ wireless transceiver, battery charger and 5 push buttons to navigate trough menus or play games like Tetris or Snake.

The Eclipse/Kinetis Design Studio project is available on GitHub. The 3D model is posted on Thingiverse. The next step would be to integrate everything into a PCB. Then every student group could use such a tinyK20 board with their robots. Or to use it as a gaming platform. Or as a remote controller to open the garage door :-).

Happy Remoting 🙂

  1. Looking good Erich, I was working on something very similar for the Blaze Kickstarter however I ran out of time and wasn’t able to complete it.

    • It is available to the students as part of their course work. But we have a few which could be made available outside of the university. Send me an email to the address noted in the about box of this blog if you are interested.
