Barebones Arduino on a breadboard

arduinoBreadboard.jpg

Here is a truly barebones Arduino setup. Just the Arduino chip and a few support parts. This has to be close to the simplest and lowest cost way to play with microcontrollers. The only special parts are the resonator and the Mega168 programmed with the Arduino boot loader. Everything else you should already have as an electronics hobbyist.

HOW TO - Make an aux-in for the Bose SoundDock

Will O'Brien posted this short how-to on Hack A Day because he says the site gets quite a few hits on posts about the Bose SoundDock portable speaker system. On my site, Street Tech, the review of the SoundDock also gets lots of traffic, so there appears to be a lot of SoundDock enthusiasts out there...

There is a solderless way to hack an aux input for the Sounddock.

(1) Go to Wal-mart (or elsewhere) and buy the Griffin Dock Adapter for iPod Shuffle (~$20) and a Belkin Speaker and Headphone splitter (~$4). (The Belkin splitter is needed in order to fit properly over the Shuffle plug on the device, but other cables/adapters might work.)
(2) Remove the existing adapter plate and replace it with the Dock adapter.
(3) Set the switch to speaker. (Very Important!)
(4) Plug in one end of the Belkin adapter and you are ready to go! Any input signal automatically activates the Sounddock. Now you have a fully functional female and male stereo headphone input for your Sounddock.

-->Total cost ~$25 and no soldering required.

Make Your Own Printed Circuit Boards - Make: Video Podcast

mp4 | mov | hd-appletv | 3gp | 3g2 | blip | youtube | itunes | pdf

This week I teamed up with Xander Hudson to make PCBs. Besides being pretty, making your own printed circuit boards is fun and you can have a prototype board ready in a few hours.

First you need a design. There are a bunch of timer circuits in the latest issue of Make: that are begging for circuit boards. There are lots of designs online at places like discovercircuits.com

Eagle CAD has a bit of a steep learning curve, but it's got a library of parts that you can drag and drop onto the board that make getting everything the right size and proportion easy.

737226400 13Dd89E25B-1

If you don't want to design your own circuit, you can download all the source files, including a pdf, and print them out on a laser printer out to make the Make: Light. - Link (Zip File)

Also, make sure to download the pdf that goes along with this podcast that includes a great article by Andrew Argyle that includes material lists and step by step instructions. - Link

Weekend Projects is sponsored by Microchip Technology. Check out their seminars and the Microchip Masters Conference.

Make Your Own Printed Circuit Boards - Make: PDFcast


728615363 E526D49E41

This weeks PDF includes an article by Andrew Argyle with instructions that will take you step by step through the PCB making process. Originally printed in Make: Volume 2, this article has the material lists and extra notes that can't be found in the video. - PDF Link

To see chematic and PCB board designs, you'll also want to download this zip file which has all the source files in it so that you can get started making the Make: Light right away. - Link (Zip File)

Making PCB boards if really fun. When you make your own boards, upload them to the Make: Flickr Pool. I'd love to see them!

R2-S2 (Steam R2-D2) gets props on Star Wars Blog

r2Steam2.jpg
Make pal I-Wei Huang, a.k.a. Crabfu, the steambots guru, was interviewed by Bonnie Burton for the Official Star Wars Blog...

How do your skills as an animator help when you make these cool creations?

Being an animator, you tend to see things in a different way, and can't help but notice subtle details of how things move and work, especially in motion of humans and animals. To be an animator these days, you sort of have to have a balance between being artsy-fartsy and techy-geeky. I like seeing mechanical things work, because it's visual. You can watch and study the transfer of power, and figure out how one thing drives another. When it comes to non-visual things, like electronics, I have a hard time grasping concepts of how everything work together.

Drive tray guitar

 Coin-Operated.Com Wp-Content Uploads 2007 07 Dtg
Jonah writes -

This "Drive Tray Guitar" was built by a workshop participant during our MIDI Scrapyard Challenge workshop held at Eyebeam in NYC last weekend. Basically it was built by integrating an old computer's CD drive into the body of an acoustic guitar and using the "Ejection" mechanism to create a "strumming" function that when moved back and forth connected up the "strings/wires" to produce sounds. Really nice use of an existing instrument mixed with some electronics detritus from the scrapyard!

Auto-recorder project

 School Recorder Recorder5
 School Recorder Recorder3
Amin Rahimi's recorder project...

Being the huge band geek that I am, I decided that my project should involve some kind of musical instrument. Given the limited time that I had to complete the project, I decided to have my computer play a simple Yamaha recorder that was sitting in one of my drawers.

Because of a limited budget, I used mostly components that I already had. The air compressor came from my car horn, which is capable of producing 138 decibels. This was clearly not the ideal compressor to use, but it was enough to get the project done without spending loads of money. As a result, the sound of the motor drowns out a lot of the recorder pitch as you can hear in the videos linked at the bottom of this page. You'll also notice that the speed of the motor changes with the pitch of the recorder to create the proper tone. This was done using pulse width modulation.

Nixie clock build / review

Yngvarr writes -

Well, I built a nixie clock in the past, so why build another one? I saw this nice clock listed on makezine recently, and really couldn't resist...The kit arrived, well packaged. You can see below that the kit maker put a lot of personal effort into this. He supplies as much as feasible. That means wire, shrink tubing, solder and solder wick. Nice touch.

Sticks and Stones Version 2

Last year some friends and I made a Rube Goldberg machine in the woods out of sticks and stones. The Discovery Channel Canada asked us to do it again and Jesse, Brenda, and I went into nature again and made it bigger and better and more complicated. Jesse recently dug the footage out of the archives and edited together this widescreen version where you can see both perspectives at the same time. Jesse's got more photos and videos here and I've got a photset here. Quicktime version - Link
