Built-in Coffee Table Lightbox

diydollarstorelightbox

[Flyingpuppy] sent us this tip about her cleverly-concealed pull-out lightbox drawer. Her resolution for the new year was to make more art, so she filled this coffee table with art supplies and decided she’d draw while relaxing in front of the television. She also wanted a lightbox nearby, which originally involved hacking the entire tabletop with some acrylic, but she eventually opted for a simpler build: and it’s portable, too! The drawer’s lights are battery-powered, so you can pull the entire thing out of the table and drag it onto your lap, if that makes drawing more comfortable.

[Flyingpuppy] sourced seven inexpensive LED units from her local dollar store, which she mounted to the back of the drawer with some screws. The rest of the drawer was lined with white foam board, the bottom section angled to bounce light up onto the acrylic drawing surface. Because she needs to open the case to manually flip on the lights, she secured the acrylic top magnetically, gluing a magnet to the underside of the foam board and affixing a small piece of steel to the acrylic. A simple tug on the steel bit frees the surface, providing access underneath. Stick around for a video below.

Hackaday Links: January 2, 2012

The worst computer keyboard, ever

[Gerardus] found an old BBC Master Compact computer for $15. The only problem is the computer didn’t have a keyboard. It’s not a problem if you can make a keyboard out of an old breadboard. It’s not a Model M, but it works.

Emergency ribbon cable repair

[Thomas] works in a hospital. One night, a piece of equipment went down because of a bad ribbon cable. Doctors were yelling at him to get the equipment up and running so out of frustration, he took stapler to the cable. It held up until a replacement arrived. Check out these pics: one and two.

Nobody remembers Little Nemo: Adventures in Slumberland

Here’s [Alan]‘s gigantic Nautilus art car with a huge mechanical iris. Just watch the video and be amazed. We won’t hazard a guess as to how much money went into all that brass and copper, but we can confirm an Arduino controls the iris. Check out the build page.

Light up street art

[Grissini] put up an instructable for a light box that displays [Bansky] street art. We’d go with some RGB leds and a [Keith Haring] motif, but more power to ya.

A theater wind machine

This wind machine was built by [Willaim] for his High School’s choir concert. It’s basically a concrete form tube with plastic lids taped on and a piece of pipe serving as an axle. The machine makes a wind noise with the help of some nylon pants.

DIY lightbox repurposes useless scanner

[James] didn’t like losing detail when scanning in photographic negatives, so he repurposed an old scanner and turned it into a lightbox.

The Flickr set of the build shows [James] installing a compact fluorescent bulb in the body of the scanner. Aluminum foil reflects the light, and the scanner glass is painted white for diffusion. [James] is quite happy with the result, and is amazed by the detail seen in the negatives under magnification instead of scanning.

We’re trying to figure out [James]‘s though process in deciding to build a light box, and the best we can come up with is the hackaday mantra of, “Of course I can do that myself.” Even though he seems happy with his project, we’re wondering how hackaday readers would improve it. Maybe several dozen red, green, and blue LEDs to adjust the color temperature? Post your ideas in the comments.
