Project enclosures the right way

[Stephen Eaton] created an enclosure and shared his process in a pair of blog post. We thought is was amusing that he remarks on how rarely his projects get the to point that you’d want to make an enclosure for them. We’ve certainly got a lot of bare-PCB creations lying around. But when it does come time, we think his fabrication method is a good way to go.

First of all, he didn’t start from scratch. He already had a SparkFun project case sitting around. The problem is figuring how to make it work for your situation. We’ve used a drill, a Dremel, and a file in the past and that yields passable results but nothing that would be mistaken for anything other than a carefully mangled project box. [Stephen] decided to mill the openings he needed from the box, which yielded professional looking results. He started by emailing SparkFun and asking if they could give him a 3D model of the project box and the obliged. He then modeled the LCD screen, LED light pipes, button, USB port, and SD socket. From there it was off to the mill with a custom jig and a few tricks we think you’ll appreciate. The end result is just another reason to build the CNC mill you’ve had on your mind for so long.

Student Soaker, wireless water gun

As far as pranks go, [Austin Shaf’s] wireless hidden water gun is a real treat. The video above goes over a brief explanation and shows the setup in action. The prankster holds onto a wireless AVR remote, and when the unsuspecting victim walks by, he activates a second AVR controlling a pump; spraying water everywhere.

While most of us are out of school by now, the project would still be a fun office or perhaps street prank. If you’re one for registering, schematics and source code can be found at AVRFreaks. Alternatively, check after the jump for a copy of both.

Cornell final project list

Looking for an interesting project to do using an Atmel Mega644? Students at Cornell University have got you covered. They were required to choose, design, and build a project using the microcontroller; and this year is quite promising with video object tracking, the always popular theremins, helicopters, Potentiostats, even Pavlovian conditioned mosquitoes, and more.

Of course all the previous years are included as well, making over 350 projects total.

How to make your project an Internet sensation


We’d like to spend some time talking about documenting your project and sharing it with the world. For many, the goal is to become an Internet sensation, hopefully for the right reasons. Taking a bit more time to make certain you do a great job of sharing your information will pay off. Here at hackaday.comwe focus on technological wonders but these guidelines should work well at improving the desirability of anything you might want to share on the interweb.

High altitude balloons

We received quite a bit of tips, after posting about the 150$ high altitude balloon project, from communities and teams who had done similar tasks. There is more to these projects than simply filling a balloon and attaching a camera, so in order to allow everyone their 7 seconds of well deserved fame, we’ve compiled a quick list of similar high altitude balloons. Catch it after the break.

How-To: Make an RGB combination door lock (Part 1)

Part 2 can be found here

Putting a custom designed electronic lock on your space seems like a geek right of passage. For our latest workspace, we decided to skip the boring numbered keypad and build a custom RGB backlit keypad powered by an Arduino. Instead of typing in numbers, your password is a unique set of colors. In today’s How-To, we’ll show you how to build your own and give you the code to make it all work.

Metalab’s LED matrix display

Our friends at Vienna’s Metalab have been working on this project quite a while. Soldering their hearts out to create an FPGA controlled monochrome LED dot matrix display. It’s 48×72 array totaling 3,456 LEDs, soldered by hand. It creates some serious geek bling thanks to an mplayer plugin developed just for the project and it runs up to 72fps. Build details and source code are on the project page. Be sure to check out the awesome video demo below.
