HOW TO - Hidden door bookshelf
Broken shows you how to make your own hidden door book shelf -
Wall to wall bookshelves that conceal a hidden door. Made without casters.My home office was messy. After I am done it will still be messy but now it is finished AND it has the secret feature. Well it was secret, till I wrote this.
In one wall of my home office is a 5 feet tall 2 feet wide door to access the storage area and crawl space under the garage. This is where we put holiday decorations, old stuff, and junk.
This wall was the perfect spot for floor to ceiling bookshelves , which I have done lots of , but it had this door in the middle of the wall. The perfect answer was a bookshelf that opened.One day my father in law visited and we started drawing pictures of how book shelf hidden door could work , how to hinge, where to hinge, how to hide opening, etc.

HOW TO - Read embedded flash chips
David writes in -
NAND flash chips are used in all sorts of electronics for storing information/firmware etc. If you are interested in trying to get the information out to study, then I may have something useful for you. This is how I read the flash chip without removing it from the device.

Solar powered Picaxe Microbot (Vibrobot)
Chipwhich sent in this solar powered microbot based on a Picaxe (PIC with bootloader) -
This is a small solar powered progammable robot. It's design was inspired by BEAM robots, but whereas those devices are usually entirely hardware based, I favor systems which rely on software. Allowing programmability, however basic, introduces a whole new level of flexibility.This microbot is also called a vibrobot because it vibrates in order to generate horizontal motion. Because it is microprocessor controlled, it can sense stimuli and respond as programmed. The low power requirements of the components lend themselves well to solar power stored via a super-cap.

HOW TO - Make a Squawkbox - Your personal vox
Matt wrote in with his article for the instrument he to his local Dorkbot music event in Columbus last week, he writes -
This project started as an instrument for Sonic Tooth, our local Dorkbot music event. I was looking for something where you could put any sound into the mix.As an instrument, it's basically a mash-up of an answering machine and a megaphone. It ends up being a small package with a loud punch, so you could use it to play the same sample over and over (and over...). It uses a solid-state recorder with a 120 second capacity (Winbond's ISD25120)
The really cool potential that I didn't explore in this project is the ability to control the recorder via a microcontroller. It looks like the recorder's memory is addressable via a 10-bit address setting. With that, you could have the resulting playback be driven by any number of environmental stimuli. I was looking at using an Amtel ATiny13 to drive it, because I only really needed a 4-bit address space, leaving 4 ADC lines for input. But, that's all to come still.

HOW TO - Flashlight bulb socket for EXPERIMENTS
Westfw writes -
Flashlight bulbs are common, easy to find, and inexpensive (especially in bulk), but they are a pain in the neck to attach wires to, which somewhat limits their use in assorted hobby projects, especially when children are involved.The picture shows a "socket" that will hold a normal "flanged" flashlight bulb (somewhat) securely in contacts with normal wire. I'll try to get more "process" pictures if I can find my tongue depressors, but the finished-product photo should show most of what you need to know...

Apple bus mouse as a garage door opener
S1axter writes -
So I got bored tonight and started going though my box-o-cables and came across an old Apple bus mouse I had gutted years ago. I always wanted to turn it into a garage door opener but never got around to it. Well, coincidently the garage door opener for my apartment parking is the perfect size to sit inside the mouse with room for a switch.Geeksinside.com - The Domain of the geeks - [via] Link.After some probing around the opener PCB, I found two easily accessible leads for the main switch, and used wirewrap to trace them out of the unit. Wirewrap around the terminals seemed easier than soldering them. With a $1.15 tube of Krazy Glue, a nylon washer and a PCB stand off, I got the switch just below the button so when screwed together it had about the same throw as the original mouse. I also tapped a lead from the LED on the board and ground to wire up a new LED where the old mouse cable went.
I took some pics, so take a look and remember, you would be amazed at what you can do with "junk".
Interesting find, as you can see in the pics the unit has a PIC16F54C. If I had some better tools than a multimeter and a collection of screwdrivers I would have tried to dump the code from the PIC; a project for the future :-P

HOW TO - Make big warm fuzzy secret heart
Here's how to make a fuzzy heart that purrs when you hug it! Rachel writes -
This project is a pillow, which I've chosen to make in a heart shape, with a secret surprise inside. When you hug it, squeeze it, sit on it, whatever - it purrs to you!I have made a couple of these and I leave them on the sofa for unsuspecting visitors.
I've been interested in touch and pressure sensors in soft toys for a while now, and this pillow is about the simplest sensor/motor combination you can do. It consists of an outer fabric shell, a battery/motor assembly, and two fabric switches that act as pressure sensors.
I will be showing these and some other variations off at the Maker Faire this May 19th and 20th with my collaborator, Annie Shao. Come see them in person!

Three magic metals
Producing cold with electricity and a "Quicksilver Heart" that beats - from Popular Science 1936...
You are accustomed to seeing an electric element in a toaster or radiant heater grow red-hot when current passes through it--but did you know that when electricity flows through joints of certain metals, it produces a cooling effect? Have you ever made a drop of murcury behave as if it were alive or prepared a pair of magical alloys that are solids when separate, and a liquid when mixed?These are a few of the fascinating experiments that you can perform with metals, using three in particular that you may not have employed before in your home laboratory--mercury, antimony, and bismuth.

AVR based digital compass
Jheissjr has a good AVR - digital compass project...
I found that there was no example code anywhere on the internet for interfacing an AVR to the HMC6352 so I thought I would post mine for people in the same position. The code is based off the Atmel App. note AVR315. Simply hook up the SDA and SCL lines from the ATmega to the HMC6352 along with a 5k to 10k pull up on each line.

$10 DNA replicator
Lots of makers sent this in today, a $10 DNA replicator... Ben writes -
A pocket-sized device that runs on two AA batteries and copies DNA as accurately as expensive lab equipment has been developed by researchers in the US. The device has no moving parts and costs just $10 to make. It runs polymerase chain reactions (PCRs), to generate billions of identical copies of a DNA strand, in as little as 20 minutes. This is much faster than the machines currently in use, which take several hours.

Modified ink printer churns out electronic circuits (experimenter needs help!)
Mdaughtrey writes in with a request for help modding an ink printer to print out circuits... -
So I've been tinkering with this, just using the chemicals and Q-tips to put it on paper. The conductivity is horrendously low so far (~300K ohms/cm) but I haven't adjusted the pH of the solutions. My question is how do I do that? Ascorbic acid is, um...acidic, and I need to adjust to pH 7.2 and the silver nitrate to 6.5. Any ideas, anyone?

HOW TO - Remote desktop to a Windows server through a firewall with Putty
Jason @ Hackzine shows you how to remote desktop to a Windows server through a firewall with Putty -
Here's a common scenario: you need to make an emergency remote desktop connection to an XP server at work, but you're at home and the server is behind a firewall that blocks RDC connections.In a nutshell, ssh tunneling allows you to connect to a port on another machine by forwarding traffic through an intermediary ssh server. Using an ssh tunnel, if you have access to an ssh server behind the firewall, you can connect to services on other machines behind the firewall, including remote desktop services.
Using Putty (a rockstar ssh client for Windows), you can easily set up a tunnel for accessing RDC on your firewalled server:
Configure a new ssh session for the ssh server that you have access to (66.35.250.203 in this example).In the connection/ssh/tunnels menu, add a new forwarded port. You'll need to set up a port on your own machine (this will be the virtual, forwarded connection to the remote RDC server), so use something unused, like 3390.
In the destination field, enter the ip address and RDC port for the firewalled machine, Ie. 192.168.0.5:3389 (3389 is what RDC listens on)
Now save your session and connect to the SSH serverAt this point, you can connect to the remote server's RDC port via your own machine's port 3390. Everything that comes in and out of localhost:3390 will be transparently whisked away over the ssh connection, through the intermediary machine, to your destination server's port 3389. So instead of entering 192.168.0.5:3389 for your destination server in the remote desktop client, enter localhost:3390. It will go right through the firewall.
