The people over at Evil Mad Scientist Laboratories have an interesting project. You can download the plans for making this Sinusoidal Bracelet on your laser cutter. Don't have a laser cutter? No problem, you can have your acrylic cut from places like Pololu.

Our bracelets are cut from a single sheet of acrylic (using a laser, obviously!) in concentric wavy rings to form a nesting set of various sizes. The light plays through the transparent acrylic in fun and fascinating ways.

Now that it's fall and the apples are ripe in my neck of the woods (New Hampshire), I thought I'd share a recipe for home brew hard cider. It's a very simple first-time home brew and it's very rewarding. I've never liked the taste of beer or any other alcohol for that matter, but a good cider is hard not to like. Firstly, this Instructable will explain the process for producing all natural, organic, 100% hand made hard cider, an alcoholic beverage made through fermentation of apple cider.

So, we have a iBook G4 that was dropped on concrete (walking to the card :eek:) and when we sent it in, even though we had apple care, they said it would cost 800 dollars to repair! I was wondering if there was any DIY solution to this.

Florin made a giant TV-B-Gone... 48 IR LEDs and an ATmega8 that sends the signals to the LEDs. Source code and schematics included. He writes -

I arranged the LED’s in 4 rows of 12 pieces and the resistors fit quite nicely between the LED’s. I used four BD139 NPN transistors to drive the rows. It took me hours to drill and then solder this board(48 LED’s and 48 resistors mean 192 holes plus the other parts). The controller board contains an ATmega8 chosen because of it’s 8k memory needed to store all the codes, an 8 MHz crystal, an LED, a tact switch and some resistors and capacitors. I designed the board so that it can also be used for other projects.

[garygadget15] in the UK has an interesting youtube page showing an electric bicycle. On his page titled, saving money the “green way” he has replaced his commuter car with one of these electric bikes. He then videos the commute with both to compare the results. The DIY electric bicycle kit he uses is made by Cyclone comes in multiple wattage’s ranging from 180 watts to 1500 watts where they do a great job of showing the conversion steps. They’ve got enough detail that you could fab your own from salvaged parts if you felt like it.
