Raspberry Pi is right at home inside of a Game Boy


[Matt] still has his original Game Boy from when he was a kid. He wanted to pull it out and play some of the classics but alas, the screen was broken and he couldn’t find a source for a drop-in replacement. In the end he ordered a used unit and pulled the screen from that one. This left him with a pile of leftover Game Boy parts which turned into a Raspberry Pi case project.

Since the RPi doesn’t have a power switch he thought it would be pretty neat to incorporate the Game Boy power switch. He was able to cut out one section of the original PCB that included the switch and one mounting hole. This kept the switch aligned with the case and gave him some pads to solder the incoming USB cable and the jumper wires to the RPi board. In the image above the power LED is on. He mentions that there was an issue with that circuit; the voltage drop across the LED was messing up the feed to the Pi so it’s disabled for now.

We’ve embedded a couple of images of everything inside the case after the break. If you’re a fan of this hack you should also take a look at the Game Boy hard drive enclosure which uses the same pixel art printed on paper effect for the screen window.

Heating, bending, and gluing to make acrylic enclosures


You can do a lot with acrylic and few tools. If you’re just starting out we’d suggest taking a look at [Michael Colombo’s] guide to heating, bending, and gluing to create custom acrylic enclosures. Chances are you already have most of what you need. The one tool you might be lacking is a heat gun.

The process starts with math. Before cutting the acrylic down to size you need to calculate how much you need. Next [Michael] demonstrates his cutting technique using a Dremel and a cut-off wheel. We prefer to clamp along the cut line, score many times with a razor knife, and snap the stuff. But you can also send it through a table saw if you have the right blade.

The bending technique he uses starts by clamping boards on either side of the bend. The acrylic left sticking out is pushed with a scrap board while the bend is heated with the heat gun. Once all of the corners were made in one piece the sides were glued in place. This last step can be tricky. The acrylic glue is made to work with perfect seams, so make sure your cuts are clean and the bent pieces line up.

The process was documented in the clip found after the jump. If you’re looking for a more targeted heat source check out this dedicated acrylic bender.

One method of fabricating translucent faceplates


Enclosures are the bane of electronics engineers (or so says [Dave Jones] of the EEVblog and The Amp Hour). But fabricating a case that looks great has been getting easier lately. [Eric Forkosh] produced this professional-looking translucent face plate with a minimum of effort. He found a way to use a laser cutter to etch icons in acrylic.

Admittedly, this is not very involved. But just look at the quality he achieved. The secret to his success (aside from having a quality laser cutter on hand) is to use high-temperature spray paint. The acrylic is coated in paint and allowed to dry before heading to the laser cutter. By using the rasterize setting under low power he kills two birds with one stone; the paint is etched away while the acrylic is left a little bit rough to act as a diffuser for LEDs behind the panel. [Eric] cautions against using regular spray paint. In his write up he shows off the unsightly results of doing so.

This makes a great addition to some of the case options out there. One that we have been keeping our eye on is the Sick of Beige initiative being spearheaded by [Ian Lesnet].

Adventures in mold making and making your own enclosures


The folks at SC-3000 survivors have been working on a cartridge capable of storing dozens of games for the ancient Sega SC-3000 computer. The PCB works beautifully, but making a case for their cartridge left them with few options. They could use a 3D printer or simply collect a whole bunch of used cartridge cases, but making their own mold for a cartridge case was the best solution.

To create the mold for their multicart enclosure, the SC-3000 survivors first took an old, used case and made a silicone mold. While the first attempt at mold making was encouraging, several problems began to crop up due to the lack of vent holes and wiggling the mold before the resin had set. Before long, a proper technique to make resin casts was developed: use lots of resin, and don’t apply pressure or rubber bands to a curing mold.

We’re always impressed by what can be done with a few sheets of plastic, some Bondo, and the inordinate amounts of patience and sandpaper we see with other case mods and enclosure builds. the SC-3000 survivors put together an enclosure that rivals any Bondo build, and we’re happy they put out this tutorial.

Tutorial designs 3D printed cases for your projects


[Landon Cox] recently finished up a 3-part tutorial on designing project enclosures for 3D printing. The series is great if you have not yet tried your hand at this realm of the 3D printing universe, but there’s a lot to take away about design and modeling even if you don’t plan to print your creations.

He starts off part one of the tutorial by explaining the need for 3D printed cases. He believes it’s the natural progression after you’ve made it far enough to have your own PCB manufactured. Why not add a well designed and fabricated case to compliment your meticulously laid out circuitry? In part two he gets the design ball rolling by modeling the top and bottom portions of the case seen above in blue. The final step is to design a face plate that matches the needs of your circuit; in this case it’s DB9 and RJ45 connectors.

It’s not all smooth sailing along the way. [Landon] does actually print the case and the faceplate is just a bit too big for the the rest of the enclosure. But better too big than too small as shaving away a bit of the edges fixes it right up.

Building a Raspi case in true Hackaday fashion

[Ben] needed a case for his Raspberry Pi. Instead of going the usual laser-cut plastic or 3D printed route, he took a path far more familiar to us here at Hackaday. His case is built out of aluminum found in his basement, providing a neat reuse for some old aluminum extrusion he had lying around.

Part one of [Ben]’s thoroughly documented build goes over the process of acquiring some of this very handy aluminum extrusion. Part two covers a very neat feature of [Ben]’s scrap of aluminum: because of a pair of internal chamfers, [Ben] was able to mount his Raspi and USB hub to a separate piece of PVC and slide the whole assembly in.

The final assembly included dremeling a piece of aluminum plate for the Raspi and USB hub ports and wiring the whole thing together.

Right now the newly enclosed Raspi is working happily as [Ben]’s home server. Not exactly the use case a rugged aluminum case would see the best use from, but it looks great all the same.

This diy fume extractor will be a showpiece for your workbench

We have no idea how well this diy fume extractor works, but it sure does look great! We’ve been thinking that it’s time to stop trying to blow away the solder fumes while working on project and this might be just the kind of motivation we need. The 6″ cube doesn’t get in the way of your work, and since it includes a carbon filter it should keep the smell of burning flux to a minimum.

[Jeff’s] project basically brings together a 120mm PC cooling fan with a power source. The fan mounts inside of a steel enclosure he picked up from Digikey. The face plates that come with it were modified to accept the fan, as well as the grill hardware that goes with it. Before assembling he painted the box with some Rustoleum “Hammered” black spray paint. This gives it a texture that will hide any imperfections in your application.

We’re a bit hazy on how this is being powered. It sounds like he’s plugging the cord into mains but we don’t see any type of regulator to feed what must be a 12V DC fan. There are build instruction available but they didn’t clear up our confusion.
