Space weather receiver


This very low frequency radio reciever kit is sold by Nasa's Inspire project - a group based around the study radio atmospheric phenomena, aka whistlers. These pulses occur in a frequency range audible to us humans (1 to 30 kHz) - and they sound quite mysterious an interesting. Listen to some samples - Spaceweathersounds.com

HOW TO - Grow shiitake mushrooms


Jenny @ CRAFT writes:
Heavy Petal has a great tutorial showing how to drill an alder log and fill it with mushroom spawn-laced wooden plugs to create a super-cool log that will eventually sprout shiitake mushrooms galore.
My favorite is the last step: "Then you make omelettes."

Brainwaves in a browser

The Gnaural Java applet allows you to playback binaural beat sequences in a web browser - arrange your own programs using the Gnaural software or simply download example programs and load them via the java interface.
If you're looking for something a little 'flashier' - check out this visual HTML Dreammachine. Far simpler than Gnaural, it allows you to control the rate and color of basic full-window flashes.
You can get acquainted with the mental medium via this handy frequency chart listing each range's associated states of consciousness.
(Theta [4-7hz] FTW!)

Home Chemistry at Maker Faire

We're very excited about the release of the second in our line of DIY Science books, Illustrated Guide to Home Chemistry Experiments, by Robert Bruce Thompson. Bob also authored the first title in the series Illustrated Guide to Astronomical Wonders. At Maker Faire, he will be doing demos of lab experiments from the book on Saturday (1pm - 1:45pm) and Sunday (3pm - 3:45pm) at the MAKE Demo stage in the Maker Shed.
From the Maker Store:
Illustrated Guide to Home Chemistry Experiments
Our Price: $34.99

For students, DIY hobbyists, and science buffs, who can no longer get real chemistry sets, this one-of-a-kind guide explains how to set up and use a home chemistry lab, with step-by-step instructions for conducting experiments in basic chemistry. Learn how to smelt copper, purify alcohol, synthesize rayon, test for drugs and poisons, and much more. The book includes lessons on how to equip your home chemistry lab, master laboratory skills, and work safely in your lab, along with 17 hands-on chapters that include multiple laboratory sessions.

Maker Faire is a two-day, family-friendly event that celebrates the Do-It-Yourself (DIY) mindset May 3rd and 4th at the San Mateo Fairgrounds, CA (Upcoming.org). It's for creative, resourceful people of all ages and backgrounds who like to tinker and love to make things. Buy tickets now and save, discount ticket sales end on April 25th, 2008.
If you're in the Bay Area, or plan to attend Maker Faire add "makerfaire" to your Twitter, we'll be giving away tickets and will have updates before and during Maker Faire!

Capacitor spool phyllotaxis?

Lenore, of Evil Mad Scientist Labs, glimpses the pattern that connects in a spool of monolithic capacitors:
These capacitors... exhibit the opposite spirals of phyllotaxis that are probably most familiar from the face of a sunflower. Who knew capacitors could be so lovely?

Steve Hernandez : Machine to Machine (M2M) Communication Utilizing GSM Cellular Networks M2M communication is the process of allowing two or more machines to communicate with each other to exchange data and can encompass both voice and data communications. Steve's going to discuss using the GM862 Cellular Quad Band Module, manufactured by Telit, and available from SparkFun Electronics, in your projects.
Steve Hernandez is an engineer working in areas of telecom that he'd rather not discuss with you, but only because he doesn't like the hassle of having to dispose of your body afterwards.
Jay Swift : Bringing Up Rex In our second presentation on the RepRap project's plan for world domination and the good people that are making that possible, Jay--a member of the Baltimore/Washington RepRap Users' Group--will have us oohing and ahhing as he shows us his neonatal Darwin 1.0 (dubbed Rex by his GF) and tells us where RepRaps come from.
Jay Swift is a high school Junior who got interested in RepRap about six months ago, mainly because he wanted to do something that was more worth his time than K'NEX.
If you--or someone you know--has an interesting announcement or something to share (5 minutes or less), we'll make time to fit you in.
Afterdork
After the presentations, the exchange continues over food and drink at a nearby eatery.

Living skin breathes life into building facades
The FLARE system is a modular dynamic display for building facades that acts like a "living skin" to allow the building to "communicate" with its environment. The surface, controlled by a computer, consists of a series of tiltable metal flakes and controllable pneumatic cylinders that act as pixels based on their tilt in relation to the sun. Check out the construction details at the link below.

Deconstructing the lotus root

Windell, over at EMS Labs, takes a break from experimenting with hardware to play with his food, geeking out over the strange and cool properties of the Nelumbo Nucifera, also known as the Sacred Lotus (amongst other names):
Any plant fiber running down the length of the rhizome would be trimmed down to an inch or so when we cut the rootlet to size. And yet, the fibers drawn between the two pieces can stretch out to many times that length. The only explanation that makes sense to me is if this is not really a fiber that exists in the lotus root, but is instead a chemical-- a polymer-- that stretches into these strings when given the opportunity.
With a little more care to the preparation of the rootlet-- carefully scoring around the entire outer husk, you can pull many more fibers:

Revisiting Claude Paillard's triodes
One of the most enthusiastic responses we've ever gotten to a Make: Blog post was for the video of French radio ham Claude Paillard's built from scratch vacuum tubes. If you haven't seen the video yet, you're in for a real treat. It still triggers passionate and effusive praise, such as this comment from a former Hughes Research Labs employee:
Dear Mr. Paillard,
I worked at Hughes Research Labs (now, HRL) for over 30 years and, vividly recall how skilled and talented the technical staff was. As a physicist, I relied immensely on our technical staff to fabricate the devices that we invented, without which, nothing would have become practical. It is magnificent to see and evaluate actual devices --- made with such precision (as you so beautifully demonstrated) --- evolve from our calculations and sketchy drawings. Your brilliant work brought back such fond and wonderful memories (you would have been hired on the spot!). In our laboratories, experimental and prototype lasers were made from scratch, just as you beautifully demonstrated with the triode. The gas discharge lasers required many of the skills that you posses, for this class of laser could be thought of as a "vacuum tube" with optical windows at both ends, and filled with a specified amount of spectroscopic purity, low pressure atomic or molecular gas(es), such as helium, neon, carbon dioxide, argon, xenon, etc. Moreover, such lasers require the vacuum-tube equivalent of a filament, cathode and anode to maintain a stable electric discharge, which is used to excite the active laser's gaseous medium. In many cases, a "getter" was "flashed" in the tube (using external RF to heat it up as you so eloquently performed), and, the evaporated material such as cesium (the shiny coating one sees along the inner walls of the tube) is used to absorb contaminants (e.g., oxygen) that would otherwise render the device useless.
To those readers that have never worked in a research environment, it is easy to overlook all the fine skills that are necessary to actually fabricate a triode, each aspect of which is a specialty in itself: metal forming and machining, instrument design, vacuum technology, materials processing, high-power RF technology, glass blowing (including forming and annealing), understanding of the detailed device properties of a triode and how to characterize its electronic performance. Your work is excellent and, viewing your video is refreshing and inspiring, for you make an extremely difficult labor of love appear so effortless --- true genius! Bravo to you!!

Solar cells built into windows could change power sources forever
The Queensland University of Technology in Australia in conjunction with Dyesol has developed an innovative solar cell technology that uses dye-infused, translucent solar cells and can be integrated into windows and uses a technology called "artificial photosynthesis" where a dye similar to chlorophyll absorbs light and generates electricity. Imagine these windows installed onto every skyscraper in the world, they might generate enough power to fuel the whole city below.

Pneumatic exoskeleton makes lifting a breeze
This soft pneumatic powered exoskeleton uses electronic components to control the flow of air which transforms the burden of weight and kinetic actuation into an easier hurdle for the wearer. Unlike previous versions, this one is light, portable, and low-power and only activated when muscle assistance is needed. Pretty nice way to perform better in a road race without having to subject yourself to steroid abuse.
