Supersized Laptop Laughs In The Face Of Portability

Sometimes a project needs to go big, and [Evan and Katelyn] threw portability to the wind to build the “world’s biggest” laptop.

Stretching the believability of “bigger is better,” this laptop features a 43″ screen, an enormous un-ergonomic keyboard, and a trackpad that might be bigger than your hand. Not to be outdone by other gaming laptops, it also features RGB lighting and a logo that really pops with neon resin.

The pair started the build with an aluminum extrusion frame joined by hinges. Plywood forms the top lid and bottom of the device, and the interior was covered with a mix of vinyl and ABS to keep everything tidy. A nice detail is the windows cut in the area above the keyboard to keep an eye on the charge of the two battery packs powering the laptop. Weighing more than 100 pounds, we suspect that this won’t be the next revolution in computing.

Reproducing Vinyl Records In Resin

While most are just plain, vinyl records can be found in a variety of colors, shapes, and some even glow in the dark. [Evan and Katelyn] decided to spruce up a plain old record by replicating it in bright, glow-in-the-dark resin.

By first making a silicone mold of the vinyl record and then pouring several different colors of resin into the resulting mold, [Evan and Katelyn] were able to make a groovy-looking record that still retained the texture necessary to transmit the original sounds of the record. The resulting piece has some static, but the music is still identifiable. That said, audiophiles would probably prefer to leave this up on the wall instead of in their phonograph.

Acrylic rings were laser cut and bolted together to build the form for the silicone mold with the original record placed at the bottom. To prevent bubbles, the silicone was degassed in a vacuum chamber before pouring over the record and the resin was cured in a pressure pot after pouring into the resulting mold.
