The articles that I've scanned out of magazines (which are now out of print,
by the way) are medium-quality JPGs compressed into an RAR file. I tried to
convert these into single PDF files, but the resulting file was over 150 megs
using the highest quality scans. At this quality, the PDFs were slightly
blurred and still almost 20 megs! The JPG images are perfectly readable,
however, if for some reason you would like a copy of the high quality scans
(about 10 to 15 megs versus 2 to 5 for these versions), email me and I will
send you the link to download them.
Enough chit-chat - Please... Enjoy...

Hebot II
Hobby Electronics - November 1982
Not sure how many of you still have a ZX81 computer [as I raise my hand,
grinning], but this robot that you build interfaces with that to allow
you to write control programs. With very little modification, mostly
software, you should be able to use any computer with a parallel port.

Build the Runabout Robot
Electronics Now - March 1996
Build your own 17 function robot that is controlled by any standard
universal (or Sony brand television) infrared remote control. Three
integrated circuit are needed - MAX756 voltage converter, 24LC26 serial
EEPROM and a PIC16C56 for which the necessary source and HEX files are
included.

Build Emily - the Robot With a One-Track Mind
Popular Electronics - March 1962
Emily is a super simple robot that will follow a line (masking tape works
best) laid down on the floor. Dubbed the "Electro-Mechanical Inebriated
Ladybug" by the article's author, Emily is sure to be a favorite of all
ages. In addition to following a white line, she will also follow you if
you aim a flashlight at her.
Even though the article is dated, the circuit is still very much viable (say
that about a circuit with a microprocessor from 10 years ago!) and simple
enough to build in one night. The mechanics might take another night. Set
aside a weekend and enjoy!

Build Mousey the Junkbot
Absolute Beginners Guide to Building Robots
by Gareth Branwyn
This project was highlighted on the Make: web site a while back. I have
tried to contact the author for permission to use this with no response.
I am including this here with the understanding that I will pull it if
requested to do so by the author.
Having said that, this is a cute little robot that you can throw together
in an evening with parts that any good hobbyist should have laying around :)
By utilizing the components from an old mouse, with the addition of only an
LM386 amplifier and a 3904 transistor, you can build a light-seeking robot
of your own - saving a mouse from the landfill in the process!

Add Serial Ports to Your Linksys Router
Pulling information from various websites and datasheets, I show you a circuit
that you can build to add serial ports to your Linksys WRT54G router. The only
active component is a Maxim MAX233. With a link to instructions for using the
circuit.
You'll want this is you plan on installing Linux on router. Perfect for
controlling your next Roomba project!

My First Tesla Coil
Nuts & Volts - September 1999
Using a design in the Nuts & Volts magazine, as well as
information found on the internet, I built a Tesla Coil
that I am currently able to pull 4 to 5 inch sparks off
of and light a small flourescent tube from two feet
away without wires!
Learn from my mistakes and download the article to build
your own.

EPE Hybrid Computer
Everyday Practical Electronics - November & December 2002
This hybrid system combines the accuracy of the digital
computer with the real-time problem-solving capabilities
of the analog systems together into one unit that you
can build yourself. Not only will it fit right in with
the rest of your Vintage Computer collection - it looks
really good!

How To Build a Working Digital Computer
by Edward Alcosser
First of all, this book was published in 1967. It is no
longer in publication, therefore I do not think there
should be a problem with hosting this material for the
purpose of preservation.
Having said that, this book details how to build a
fully functional 'paperclip' computer using items found
around most homes. I don't think you'll be surfing the
web with it, but still... it's pretty cool.

If you are planning on designing and/or building your own robotic friend,
then you are going to be needing parts. If you're like me, then you can't
always afford to obtain all of the necessary components you need to complete
your project. These companies offer free samples of some or most of their
products - you just have to ask!
Or if you are looking for a source for electronics surplus, check out these
