Massachusetts Institute of Technology has been in the free online course business longer than just about everyone else. Its website is chock full of exciting riches, but navigating the site can be a challenge. While MIT groups the courses by subject area, it can be difficult to discern which courses offer more than bare-bones reading lists. So, here is a guide to finding the good stuff. It helps to think of MIT courses as coming in four main varieties, corresponding to different kinds of banana splits. The most basic variety (think naked banana) is a course outline, with a syllabus, a list of readings and maybe some lecture notes.

Building a Celtic Roundhouse The walls of roundhouses were either dry stone filled in with clay and straw, or a ring of support poles weaved with wattling and plastered in daub, or a mixture of both stone and wattling as being built here (left). Wattle and daub is one of the oldest building techniques dating back to the Bronze Age and beyond. Wattling is a way to build walls by weaving long flexible sticks in and out of upright posts. Hazel, which is pliable and grows naturally long, is a good species to use for wattle. It is also the preferred wood used by straw bale builders to pin bales together.

Even if your library is equipped with subscriptions and memberships to top of the line databases and online journals, you’ve probably had to get creative during a patron’s requested search for something unfamiliar. Secret-Knock Gumball Machine One of the best things about exhibiting at Maker Faire is giving attendees a challenge. For the 2010 Maker Faire Bay Area, I decided to combine a past project of mine, a door lock that opens only when you give a secret knock, with a standard crowd pleaser: candy. The result was this Secret-Knock Gumball Machine, which tempted and tested the crowds at Maker Faire to guess the right rhythm and receive a treat.

How Whole Turmeric Heals The Damaged Brain Long considered impossible to accomplish, new research reveals how a simple spice might contribute to the regeneration of the damaged brain. Turmeric is hands down one of the, if not the, most versatile healing spice in the world with over 600 experimentally confirmed health benefits, and an ancient history filled with deep reverence for its seemingly compassionate power to alleviate human suffering. But, most of the focus over the past decade has been centered on only one of its many hundreds of phytocompounds: namely, the primary polyphenol in turmeric known as curcumin which gives the spice its richly golden hue.

Charlieplexing LEDs with an AVR ATmega328 (or Arduino) Charlieplexing is an ingenius method for controlling many LEDs without using many microcontroller pins. You can turn on or off one LED at a time. To light more than one LED at a time, you can scan the LEDs by turning a sequence of them on and off really fast. The number of LEDs you can control is determined by this formula: N pins * (N pins – 1). For example, if you have 4 pins, you can control 12 LEDs (4 pins * 3 pins).
