Low cost Piezo film blood flow pulse sensor
The Phoenix Ambulatory Blood Pressure Monitor Project is a piezo film blood flow pulse sensor, very cool -
The purpose of the piezo film pulse sensor project is to identify and build a reliable, low power, low cost blood flow sensor. The sensor is intended for two proposed designs for the ambulatory blood pressure monitor (ABPM). They are: (a) an oscillometric cuff design (as a Korotkoff sound sensor) and (b) the blood flow velocity design.

Turn a chalk board into a dry erase board
McPhystal writes in about turning a chalk board into a dry erase board... -
I'm a teacher and have been trying to convert old classroom chalk boards to dry-erase. I've tried epoxy spray paint, Krylon, and many other types of paint. I found that the best thing to do is to use oil-based/HIGH GLOSS paint to resurface the board. Essentially, the HIGH-GLOSS paint has very little porosity and does not allow the surface to be penetrated by minor solvents such as Dry-Erase Markers. I would use the following steps for converting a chalkboard to a dry-erase board...
- Prepare the surface with 400-Grade Sandpaper (you can use a lower number, but the surface will become increasingly coarse)
- Thoroughly dust the surface WITHOUT water (water will make any imperfections swell up, and you will have to wait for the board to dry [about 24-hrs] and re-sand the area)
- Apply a quality oil-based primer to the surface with a spray gun or aroller (allow full drying time as stated on paint can instructions).
- Apply two coats of the HIGH-GLOSS paint with a spray gun or roller and make sure to follow the reapplication instructions.
- Be patient. You need to give the paint about 2 weeks for the chemicals to bond well enough. It seems like a lot of work, but it's actually quite cheap compared to a real dry-erase board.
Please keep in mind that this is for a permanent fix.

HOW TO - Recycle office paper into blank books
R. Stern writes -
I've started making blank books from recycled paper I find around work and home. The paper is blank on one side, so it provided plenty of space for notes and doodles, and even provides inspiration based on the printed matter on every other page. They tell a story about where they were created, as you can imagine an art school computer lab recycling bin would yield much different printed material than that of an accountant. Other interesting discussions that have come up about these books are that of privacy (including printed matter with sensitive personal data) and chronology (writing over the past with the present).

HOW TO - Make a custom clock - (Sesame Street - Pinball number count)
Turn a boring old cheap clock into a fun clock for folks who grew up watching Sesame street, One two three four five, six seven eight nine ten, eleven twe-eh-eh-eh-elve! Thydzik writes -
This instructable will outline the construction of a customized clock. Whilst this is specifically the construction of the clock featured on Sesame Street; the Pinball Number Counting animation, the general procedures are the same and the instructions are as generic as possible. The clock is inexpensive and an easy way to create something out of the ordinary.

Pringles wind turbine (Pleech) -and- turbine round up
Mike writes -
The Pringles Wind Turbine (a.k.a. Power Leech or Pleech) is an attempt to turn simple items found at the hardware store and elsewhere into a working low-voltage power supply. The Pleech is design to take wind or other air currents (such as from A/C ducts, dryer vents, etc.) and convert that energy into electrical energy using magnets and copper coils.

Minidot 2 - The holoclock
Rgbphil made a great clock-like project, check out the video! -
...maybe holoclock is a little bit inaccurate....it does use holographic dispersion film on the front to give a bit of depth.Basicaly this instructable is an update to my previous Minidot located here.
and re-using a lot of code and circuitry from my Microdot located here.EagleCAD files and Sourceboost code is included in the zip files attached.
Why? The previous Minidot was overly complex, from the Microdot I learned how to do an RTC on a PIC using only a 32.768 crystal and didn't need to use a special RTC chip. Also I wanted to get rid of the display chips from the previous Minidot. So now there is only a power regulator chip and a PIC16F88....just two chips.
The other reasons for an update were my Minidot was getting a bit un-reliable because of the seperate switch board and I wanted a soft fade between dot patterns as well as some sort of ambient light sensor to dim the display at night. The other Minidot was fixed brightness, and illuminated a room at night.The device was constructed with the aid of the EagleCad software package and Sourceboost compiler.

HOW TO - Make your own simple sunlight engraver!
Laser, who needs a laser! Just use the sun!
Ok, you want to do some engraving on wood, plastic, or on your hand? (no, not really) don't feel like buying one of those expensive wood engraver irons? Want a foolproof way to make nice engravings without worrying about your hand slipping and botching the whole job?THIS IS FOR YOU! If you like simple, useful, and easy processes, give this a try. this just takes a few simple steps, and is very easy to do. You need NO experience with tools. If you can stick something with tape, and use a knife, you're set. If you can't... well, there's not much I can say about it, but that now is a good time to learn!

Building an embedded Asterisk PBX
David is doing a lot of great work with open source hardware telephony, check out the embedded Asterisk he's working on... -
The IP04 is a Four Port Embedded IP PBX that runs Asterisk. The hardware design is 100% open. I just built the first IP04 prototype (really built, as in soldered), and would like to tell you about it. This post talks about the IP04 hardware, the bring up, an explosion (!), and compares the IP04 with the Digium Asterisk Appliance.Curiously, hardware hacking is getting cheaper and easier. For example the tools for surface mount work are reasonably cheap (a soldering iron and stereo microscope), there is plenty of free CAD software, low cost PCB fabrication, and web based components stores like Digikey.

HOW TO - Make lenticular movie art (changes when you tilt)
Dave writes -
I have a good friend who is an awesome artist. She has given me all sorts of great paintings in the past few years. I wanted to give her a piece of art that would really stand out as different.I wanted to experiment with lenticular sheets because I have always been amazed by them ever since I dug the first one out of a cereal box as a kid. These are the sheets that make an image change whet you alter the angle you are viewing it at. To learn more about lenticular lenses - wikipidia
We both have the movie "fight club" as one of our top 5 all time movies so I decided to use this as a theme.
Please note that the animated gif is a composite image because my camera takes horrible images of the picture with the lenses in front of it.

DIY camera GPS project for Nikon DSLRs
Chris writes -
This page describes the steps I went through in my project to connect a Garmin eTrex Summit GPS device to a Nikon D200 camera body in order to record location information in the EXIF data of images captured using the setup. While this procedure worked fine for me, I do not take any responsibility for you or your equipment should you try this yourself.

USB as a power source - uber guide
Wow, this is a mega-uber guide to using USB as a power source, handy!
The Universal Serial Bus (USB) has become a popular method of connecting computer peripherals. The original USB 1.1 specification limited data rates to about 12 Mbits/sec. The updated USB 2.0 spec increases those rates to up to 480 Mbit/sec. Both versions of USB can provide DC power to peripheral devices. This power form is the subject of this page.USB is less expensive than FireWire because a dedicated FireWire controller chip set isn't needed. The computer's CPU does the USB controller function in software. Under good conditions, USB can work nearly as well as FireWire, but at sustained high data rates, USB will sag under the strain. FireWire tends to work better but cost more therefore USB 2.0 is more common, especially in lower end hardware.
