Intro to the Arduino - Weekend Project PDFcast
This week, Joe Grand and Bre Pettis bring you another Awesome Electronics Workshop! This time you'll learn about the open-source microcontroller board, the Arduino, ahem, the ARRR-duino. Make sure to download the PDF to see the schematic! - PDF Link
You can get an Arduino board in the Makezine store at or you can find plans to make your own from off the shelf parts. Then get some components and start playing around! You'll want to go wander around the Arduino website and the Arduino playground where users can share ideas and benefit from their collective research. Once you've checked that all out, go get thne software. Whatever projects you make, take pictures of them and upload them to the Make: Flickr pool or you'll have to walk the plank!

LED "Swimmies"
What happens when you cross an LED Throwie with a Koi fish? You get LED Swimmies, a.k.a. Lightfish. Basically they're just a Throwie sealed inside of a colored plastic fish. Artist Karl Klar did an installation of 500 of these Swimmies (which don't actually move) in the pond outside of the new Ars Electronica Center being built in Linz, Austria. Visitors to the site were given fishing poles with magnets on them to "catch" a souvenir to take home. These would be cool to put in a home pond or pool for a nighttime backyard party.

Cooking up a cheap digital o-scope
Update: Since, as a reader so astutely pointed out, we already blogged this item (the ONE time I forget to search for prior postings), may I interest you in a Parallax USB Oscilloscope? It was featured on the Introduction to Oscilloscopes Make: Podcast back in February. It's a 2-channel digital scope that looks pretty impressive for the $140 pricetag. It's seen here in its Understanding Signals educational kit form, which includes a guide book and additional parts for an extra $20. Such a deal!
Parallax USB Oscilloscope - Link
We now return you to our regular blogcast, already in progress...
If you're looking to learn more about oscilloscopes, but don't have a lot of money, you can get started on the cheap by using a PC scope with an oscilloscope hardware module. Over at fpga4fun, they've put together a "recipe" for making a hardware interface using a Pluto FPGA board and a Flashy acquisition board. The parts will cost you between $80 and $100, depending on what you already have on hand. And you only end up with a single-channel oscilloscope. But you can get a two-channel o-scope by replacing the Pluto board ($40) with a Saxo board ($90). and the single-input Flashy ($30) with a FlashyD ($70). As you can see, the cost starts to mount (bringing eBay bargains on analog scopes within the ballpark), so I'm not sure how sensible this is if you're looking for an everyday piece of test equipment. But as a fun electronics project... ?

Open source hardware: Birth of a long tail market?
Matt Hartley @ Itmanagement has an interesting article about open source hardware (I found it because of the MAKE mention). Worth a read, post your thoughts in the comments -
With open source software becoming a household name, another open source movement that may one day see some fanfare is already taking shape. Open source hardware, which I once thought to be little more than a pipe dream left over from a bygone era, is proving to be a dream that it is very much alive and growing.Open Source Hardware: Birth of a long tail market?

"Insanely hot" DIY hot air soldering iron

DIY Tea timer
Rob writes -
Guido knew the secret to a perfect cuppa. It's all in the timing. So he designed a battery-powered tea timer with a built-in LED display that will brew a perfect cup of tea every time. It's simple: just fix a tea-bag on the tea timer's extension arm, place a mug of hot water underneath it and push a button according to how strong you like your tea. The microcontroller-operated, 5V circuit provides a servo motor with control pulses to lower and raise the arm and the power supply is switched off automatically via FET.DIY Tea timer - Link.

The Hexipod 3
Brian writes in -
I built this a few years ago. I had seen all the nice hexapod kits from lynxmotion. I figured I could do the same thing, but for less money. So I got 12 servos, an OOPic microcontroller (www.oopic.com), and a bunch of basswood from the local hobby shop. I had just started my "maker" lifestyle, and I didn't have a lot of tools. But I set out to make my own walker with a hobby knife saw, a rotary tool, a few screw drivers, some wire, and an old, OLD 120Hz laptop. A few nights later, my walker was walking. I had a controller with forward, reverse, left, right, and a programmable "dance" button.Hexipod 3 - Link.
The robot had a good life as a demo robot at a few FIRST robots events, as little kids loved to make it walk and dance. But eventually it got old, and I harvested the servos. But this little wooden robot got me walking down the path of a maker - I'm just about finished refurbishing a FREE (but dead) Emco F1 CNC mill for my home shop, which will go nicely next to the mini lathe. I hope to start documenting more of my projects on Instructables...

Arduino punk console
Here's a great music project you can build with an Arduino... Beavis Audio Research writes -
This is my first build using an arduino microcontroller. I wanted to create a simple tone output device along the lines of the 555-based atari punk console, but using solely the mcu as the tone generator. Unfortunately, that was just too simple a task with a microcontroller to play with--it was done in about five minutes and my mind was already forging ahead with a bunch of stupid ideas.Beavis Audio Research - Link.Since coding the arduino is simple, I decided to set up eight tone "slots" and then sequence through them. A frequency knob would control the freq of each slot, and a separate tone duration control would allow me to get awesome eighties video game tones. Figuring out the component wiring wasn't too tough once I'd figured out the basics of reading analog pots and digital switches.

Insanely cool, creepy "LittleDog" robot
You probably remember Boston Dynamics' BigDog, the four-legged robotic packmule, the video of which went viral last year. Here's the latest BD creation, LittleDog. It's astonishing, when a robot becomes this adept, ambulatory, how organic it seems, life-like. The robot: it plans. And there's something uniquely unsettling about that.

Ethduino
Ethernet + Arduino = Ethduino -
An ethernet enabled Arduino (ATMega168*) using Microchip's ENC28J60 IC. It based on Procyon AVRLib. However, on the contrary of the library one of the main goals of the code is to free the µC as much as possible from processing by using built-in features from the PHY. Although this has negative effect on porting the code, it is a necessary step to obtain a viable network solution for a small chip like the ATMega168...Ethduino - Link.

All in one remote for cameras
This all in one camera remote is now an Arduino project, nice! -
One of my other hobbies is photography, and, about a year ago, I purchased a new digicam - a Panasonic FZ30. I joined the Panasonic forum on the dpreview site. One of the posters, a programmer and electronic hobbyist, designed a nifty wireless remote using a very inexpensive RF transmitter/receiver combination that he found on eBay. After he'd perfected that, he began designing an interval timer using a Radio Shack egg timer.AI-1 ("All-in-one") Remote - Link.At the time, I had just discovered the Picaxe 18X microcontroller. I realized that the PICAXE might make a good vehicle to power such photographic accessories, and that some sort of "do everything" remote might be a good project to learn how to use the PICAXE. Even better, the Picaxe is programmed in a very simple form of BASIC. Programs can be downloaded to the processor over a serial link from your computer -- no programmer is required. And the development system is a free download. In this case, a Picaxe is an ideal vehicle for "gizmo" design, since anyone can duplicate a project designed with one of these chips, and many can do design modifications or original designs with them.
