Pelican Case Becomes Thumping Bluetooth Speaker

October 25, 2019 by Lewin Day 5 Comments

Pelican cases are great if you need a rugged enclosure to protect some sensitive gear. They’re also highly moddable, and can make a great base for a Bluetooth speaker build.

Like many modern builds, this is very much a case of wiring together a series of off-the-shelf modules into a larger whole. A Tinyshine Bluetooth audio board is hooked up to a Dayton Audio Class D amplifier. Class D amplifiers are a great choice for any portable audio application for their compact size and good power efficiency. Power is supplied by a hand-built 3-cell 18650 pack, while a standard buck converter and battery protection board are subbed in to make sure the batteries stay happy.

Not wanting to skimp on audio quality, a pair of Dayton Audio full-range drivers are installed, negating the need for a crossover install, or multiple drivers per channel. There’s a third passive driver on the back side as well, though we’re not 100% clear on its purpose. If you’re clued in, let us know in the comments.

It’s a project that serves as a great blueprint for anyone wanting to build their own high-fidelity Bluetooth speaker. The relevant modules are all readily available – it’s just a case of hooking them up to a nice amp and a decent set of speakers. The design is all up to you – whether you go for a pipe, a bag, or something altogether entirely. Happy hacking!

Raspberry Pi Field Unit (RPFU)

August 13, 2015 by James Hobson 35 Comments

Raspberry Pis are great for tons of projects, but if you want to use them outside, you’re going to need a waterproof enclosure. Not happy with what was available, [Jay Doscher] went all out and created the Raspberry Pi Field Unit — a piece of tech that looks straight out of the Call of Duty franchise.

Wanting it to be extra durable, [Jay] started with a Pelican Case 1300 — the standard in electronics protection. These come with a Pelican panel mount, so he had some plastic laser cut specifically to fit the panel mount, and attach all of his components. Speaking of components, he got only the best — inside is:

A Raspberry Pi 2 with a few PIHATs (permanent prototyping shield)
A 10.1″ IPS display
A high power wireless USB dongle
Weather proof USB and LAN connectors
An RTC for when it’s off the network
A 12V power supply for running off solar panels
DC-to-DC adapters to bring it down to 5V
A whole bunch of hardware from McMaster-Carr

Sound Blimp Makes Camera Quieter And Waterproof

September 23, 2013 by Marsh 23 Comments

The D-SLR “crunch” sound can be pretty satisfying. Your camera has moving parts and those cell-phone amateurs can eat your shutter actuation. If you’re a professional photographer behind the scenes on a sound stage or at any film shoot, however, your mirror slapping around is loud enough to get you kicked off the set. [Dan Tábar] needed his D800 to keep it down, so he made his own sound blimp to suppress the noise. As an added bonus, it turns out the case is waterproof, too!

[Dan] got the idea from a fellow photographer who was using a prefab Jacobson blimp to snap pictures in sound-sensitive environments. Not wanting to spend $1000, he looked for a DIY alternative. This build uses a Pelican case to house the body of the camera and interchangeable extension tubes to cover lenses of various sizes. [Dan] took measurements and test-fit a paper cutout of his D800 before carving holes into the Pelican case with a Dremel tool. One side got a circular hole for the extension tubes, while the other received a rectangular cut for the camera’s LCD screen and a smaller circle for the viewfinder.

Lexan serves as a window for all of the open ends: LCD, viewfinder, and the lens. [Dan] snaps pictures with a wireless trigger, saving him the trouble of drilling another hole. You can hear the D800 before and after noise reduction in a video after the break, along with a second video of [Dan] trying out some underwater shots. If you’d rather take a trip back in time, there’s always the 3D printed pinhole camera from last week.

Take Your PS3 On World Tour

January 28, 2011 by Mike Szczys 22 Comments

[Lossfresnos65] must be planning to do a lot of travelling because he’s entombed his PlayStation 3 in a Pelican case. Inside you’ll find some diamond-plate bezel to cover the console itself and used to surround the 19-inch high-definition television that is mounted to the lid of the case. In the picture above you see the door that lifts to reveal foam cutouts for a TV remote and two six-axis controllers. There’s no battery and no wireless Internet, but connection for the power cord, Ethernet, component video, and HDMI have an external port on the base of the enclosure. There’s also two fans to keep everything cool, and on the front you’ll find two USB ports and a headphone jack. After the break he shows off the finished product but there’s no internal build photos to be found. We linked his forum post at the top as ask him and perhaps he’ll deliver the goods.

Pelican Case Xbox 360

[Ben Heck] has put the final touches on his Pelican case Xbox 360. This prototype was constructed for use by troops stationed overseas. When he announced the project in October, he already knew some of the hurdles he would face. An industrial Velcro style product is used for all component mounting so the air/water-tight seal of the case remains intact. He sanded the surface so that it would stick better. [Ben] mentions that he ended up using less Velcro than he planned on because it held so well. Not being able to cut the case meant the DVD drive had to be converted to top-loading. The tray movement limit switches have been relocated so they now respond to lid position. He regrets not being able to motorize the lid, but let it go since this is still just the first attempt. Extra copper was added to all of the heat sinks to improve cooling. This Xbox is for sale and he’d love to hear from anyone that wants to put it into production. The write-up has a ton of pictures and you can see a video of it below.

Pelican Case Xbox 360

October 8, 2008 by Eliot 13 Comments

We were surprised the last time [Ben Heck] was building a Xbox 360 laptop, yet here’s another one. Well, it’s not a laptop exactly, but an Xbox 360 built inside of a Pelican case. After receiving several requests for a similar device for people stationed overseas, he finally decided to try it out. The goal is to get all the components into the case so that the watertight seals are intact. It’s only partially complete right now and he notes that one of the major hurdles will be converting the DVD drive to top loading. The light ring and USB ports will probably be moved to the top surface, and the hard drive will be made removable. We look forward to the final writeup since there aren’t many tutorials on working with Pelican cases.
