[OFF-TOPIC] Engineering Love-Hate

¿Cómo se puede explicar que a las 3AM de un sabado estés tratando de hacer funcionar un prototipo en vez de dormir? ¿Cómo hacérselo comprender a alguien que no sienta este amor-odio que te alimenta y te consume?

[PROTO] Inmersive 3D rift (Early prototype)

When I first saw this post from Ahmet Yildirim, I though it was a very good DIY project. Several days later, something moved into my brains, so I decided to try to build a finer version, closer to what a production rig should be.

I have to admit that there is not too much to do at hardware level because there are few pieces and they do their duty better than correctly. Maybe a screen with better resolution or a more expensive gyroscope would be worth, but at this moment I only have a very early prototype and there is no room for comparisons. Once I have time enough to test it deeper, I will publish the results and conclusions here, if there is room for improvement.

For me, Software is the key for this project to work. In a more specific way I would say that in fact, 3D software renderer configuration is the most important thing. I will publish the best configurations I find in the next articles.

Ok, so let´s start! The initial components bought for testing are very similar to Ahmet´s ones. The only difference is that I will try to combine different setups of cases and lenses.

  1. Arduino Mini Pro 
  2. GY-85 9DOF IMU
  3. USB to TTL Converter
  4. 5.6” 1280×800 LCD Display
  5. 12V DC Power Adapter for the screen ( Recommended 3A, but testing with a 2A power source it is also working. Internal positive polarity on plug )
  6. 2x (50mm 5x Aspheric Lenses)
  7. Cases:
    1. Cardboard box (Early prototype) Based on the Nova from Instructables
    2. 3D-Printed ABS case
    3. Modded VR Googles for Smartphones (containing own lenses)
  8. Wiring
  9. Ellastic bands to attach it to the head and foam for border padding
  10. Hot silicone
