HOW TO - Underwater video camera / camcorder Housing for less than $50


Gomiboy writes -
Since getting my first digital camera, and later, my first video camera, I have wanted to push the envelope of what these cameras can do, and where they can go. I have taken them on roller coasters, mounted them on my motorcycle, pulled out the IR filter and taken infrared photos. In short, anything is worth a try (thanks to Instructables for inspiration!).HOW TO - Underwater video camera / camcorder Housing for less than $50 - Link.Putting a camera underwater was another realm to conquer, and having two young children who love the pool gave me a great reason to work on this.
The purpose of this Instructable (my first) is to detail how to build an underwater video camera housing. The end result will be the ability to take underwater video on the cheap - less than $50, significantly less if you have parts on hand.
It took about 3 days to complete this, but most of that was testing for leaks or waiting for the sealant to set. Actual workbench time was less than 2 hours.

More mint-tin amp action


Michael O'Brien, a.k.a. Turbotron, has posted pics of this project to the MAKE Flickr Pool. It's a mint-tin amp based on the LM386 chip, the same op-amp chip used in the MAKE Mousey the Junkbot and Cracker Box Amp projects. The case is an Altoids box, painted gloss black enamel, the grill is from a PC power supply, and the control hardware is from The Shack.

USB POV SMD kit


This is cool, a USB surface mount version of the POV kit we carry here @ MAKE.... ohararp writes -
Have you ever seen a kit developed solely for learning how to assemble an electronic circuit of only SMT parts? Did it have BLUE LEDs? I haven't seen one with either! Expect to see all SMT components, acrylic stencil, solder paste, acrylic scraper, solder wick, enclosure, and battery all in one kit for about $30! A full instructional manual to include schematic and source code (picbasic) will also be provided. Stay tuned as we are in the process of acquiring all the necessary materials for a 50 piece run!...OHARARP LLC - [via] Link and photos.

Make a rubik's cube out of dice - Make: Video Podcast
This weekend, Action Girl and I show you how to make a Rubik's Cube out of dice, magnets and epoxy. Interestingly enough, the first Rubik's cube ever was made with magnets! We found inspiration in gfixler's and burzvingion's instructables.
The hardest part that we had with this was getting all the magnets in the right polarity!
Subscribe in iTunes and get the podcast and pdf downloaded automatically. - Link
By popular request, here's a little video of the cube actually moving! - Link

Kazuhisa Terasaki's Weird-72 wooden humanoid
Kazuhisa Terasaki is known for making whimsical robots out of wood. Basically, they're wood, servos, and an MCU. His robot Weird-7 was such a hit in Japan, he produced a kit for it. Now he's showing off a much more sophisticated bot, Weird-72, that's still mainly wood and a crapload of servomotors. Kazuhisa's website has lots of information, pictures, video and even step-by-step on building Weird-7. Unfortunately, it's all in Japanese.

Repacking NiCd battery packs


The amateur astronomy site Astromart has a short, informative piece on testing and repacking dead power tool NiCd battery packs. These packs are filled with "Sub C" cells. Taking apart a "dead" pack, you can test the individual cells and replace only the bad cells.

Firefly PCB

John writes -
The Firefly is a tube-based guitar amplifier popularized on ax84.com (a tube amp community and forum). The Firefly PCB was created so even the beginner to tube amps can succeed. The PCB is "open hardware" meaning that the PCB file is free to download and modify as well. Otherwise the PCB's are sold for $19 each. There's a detailed assembly guide as well for download at the site.Firefly PCB - Link.

MAH PONK: An open table tennis videogame



Viacheslav writes -
I wanted to do something that has a VGA compatible output. I also had an FPGA board lying around and a bad itch to do something useless. With the help of fpga4fun.com, various online Verilog HDL references and VGA timing information I made something that outputs a steady checkerboard picture to a VGA display. That was cool but after a short while the excitement dried out, I needed something more serious. My imagination is quite poor and in a short while I had two paddles on the screen.. And so it began.MAH PONK: An Open Table Tennis Videogame - [via] Link.

HOW TO - Make your own embossed business cards using acid etching

Bofthem writes -
Etch. Press. Print. Want to learn how to emboss paper for your own business cards? Create your own pattern on the computer, and etch it into a brass plate. I've wanted to make my own embossed business cards since I was handed a really incredible one at a fancy restaurant. I tried several methods of achieving the effect (photoemulsion, electrolytic etching) but ended up having the most success with a pretty simple and straightforward acid etch method similar to the one used in home printed circuit boards. I still have to work out a few kinks (such as flattening the paper after the emboss without distortion, or reorganizing the method to print before embossing) but I hope you can take something useful from my experiments, and apply it to your own projects.HOW TO - Make your own embossed business cards using acid etching - Link.

HOW TO - Build a very fancy crystal radio


I was never much into amateur radio or crystal set building, so I can't judge the technical veracity of this project, but the how-to looks very thorough and the results are spectacular. The dials, tap switch and case are so cool-looking, they make me want to build one.

Mind-boggling Transformers papercraft




You may have seen this item on Boing Boing Gadgets, or elsewhere, but if you're an admirer or practitioner of papercraft, you've got to check the link out (as I just did). This Chinese papercrafter created an incredibly detailed, articulated Bumblebee Transformer model using mainly fast-food containers (this badass cardboard dude is basically a bunch of KFC bucket lids and Orion custard boxes). I love how he uses the colored ink in the packaging as the coloring on the model, a great Bumblebee color match.

HOW TO - Control an iPod with the Arduino


Here's a great HOW TO on controlling an iPod with the Arduino, Jonas writes -
This tutorial will describe a way of controlling an iPod remote, and thus, an easy way of getting some music and sound out of your Arduino project. The remote we used was an unofficial remote I found on the worldwide auction site for around 10 USD, an opto-isolator can be found in your local electronics store.Control an iPod with the Arduino - Link.We used a TIL116 opto-isolator between the Arduino and the remote to safely send signals in between the two. The remote works by you pushing a button which closes a circuit and that is interpreted in a certain way by the iPod. What you need to do is to send a pulse to the opto-isolator that makes it close the button-circuit, and then open it again. Depending on what you want the iPod to do, you need to send a longer or shorter pulse, i.e.. a long pulse sent to the play/pause button will shut the iPod off, a short pulse will play/pause the track.
