| Project Jetsam: Bartop speed build using 100% recycled materials [Completed!] |

I think if I would build something similar, I'd just have the monitor and the controls and use it with external hardware, like an XBox 360 or a PC. And a rotatable 4:3 screen with a bezel that makes it (the screen area) square shaped. |

Thanks Emphatic! Yes, cooling is a concern and I may add a 12V fan and/or exhaust vents. The original computer case was completely unvented and had no fan - it's a very low-power (65W) all-in-one and the CPU heatsink uses the stamped steel motherboard carrier as a heatspreader. The original form-factor was basically like a [very large] tablet. |

I love the circular economy aspects. T-molding? If you round off the 90 degree angle at the back/bottom corner, you could run some continuous T-molding around the entire outside. Some small, slightly domed, rubber feet screwed or glued onto the bottom could both lift it slightly, and make it more secure when playing. Also means you can have intake vent holes at the bottom. |

Thanks Zebidee. Instead of T molding I had planned to use adhesive pvc countertop edging with a shallow 'u' shape channel profile. It should be able to handle all of the bends with some minor relief cuts on the acute outside corners, and should 'stretch' ok for the two inside corners. Rubber feet are now on the machine, had some nice 25x13mm ones left over from an earlier project. You read my mind on the ability to utilize the lift to provide for air vents in the base. If I add an intake fan I'll probably need to splice it from the output of the 19V power brick and use a buck converter... Those should be things I have on hand so they won't blow the $0 budget for the machine so far :D |

Might be easy enough to hack into the laptop's 12v rail. If you put in some small discrete holes at the top/back to let the warm air out, convection currents might even be sufficient. I like to cover holes with some scrap nylon mosquito meshing to keep pests out. I was just now thinking - I've got one of those laptop cooler bases that plugs into USB. Two big slow fans that go underneath. It came free with a laptop but I never use it, even in a tropical climate. It could be perfect for this kind of bartop. |
