I wanted to build a projector setup on the cheap… I am still designing a portable unit for the projector to sit on and to contain the wires… But here is the start of it. I built two screens, one is approx 60″ and the other is 110″ which I mounted on the wall in a spare bedroom. Both are framed out of wood with metal brackets for support and then wrapped with black plastic. The black covering helps with projected image clarity, as the bed sheets I put on top for the screen are quite thin. For the spare bedroom, i’m considering making a hanging mount for the projector with hooks for easy set up and storage.
For speakers, I found a relatively cheap 2.1 speaker bar. I had never heard of the brand, but the reviews on amazon were good. The projector is also cheap, but can support 720p and has HDMI output as well as a 2 year warranty. All in all the results were better than expected considering the entire project was under $200. I will post back once I have expanded the project to include transportation and possibly battery power for the true mobile projection experience.
I am in the process of creating a powerful laptop for my on the go needs. I got a 2011 13″ Core i5 2.3 GHz from eBay, and maxed it out. I followed some guides on iFixit.com and added 16GB of ram, and two 250GB solid state drives, by removing the super-drive and adding a hard drive caddy.
The goal is to boot Yosemite as the main operating system on drive 1 and have drive 2 split between Ubuntu 14.04.3 LTS and Windows 7. I will use Virtualbox on the Yosemite partition to experiment with some Linux distros, but I still want a native install of Linux to avoid any issues that sometimes arise from using USB on a virtual machine. The first step after installing Ubuntu (The Macbook was preloaded with Yosemite) was to determine what bootloader to use. After experimenting with some OSX bootloaders, I decided to just stick with a classic, GRUB. (GRand Unified Bootloader)
The annoying part about this setup, is that the primary drive is OSX… So every time a major update comes out, the boot options are overwritten and GRUB does not load. After every updates to OSX (which is not often) I have to hold the option key, boot to the Linux drive and run an update on GRUB.
