Drill two holes, almost all the way through, two blocks of something the same size as the outer diameter of your roller blade bearings. It's a common size like 3/4 or 7/8in. Make them identical. For the hole you are after, you need a nut on the threaded...
Take your other coupler nut, and fashion a small post coming off of it at a 90 degree angle. I welded mine. Take your corner brace, and make a second post behind the first, the thickness of the corner brace, so the main post slides on the front, and...
On this next link is where I got the info for sending the photos taken with its own email account .http://mitchtech.net/connect-raspberry-pi-to-gmail...I tested it by copying the script to send attachments in to the python editor on the rpi by first...
For the outlet power detectors:Cut the connectors off of your two wall warts and solder the grounds together (and to the ground on their Arduino)Solder the +5v wire of one wall wart to the +5v plug on the Spark core, and the other to digital input 3...
Step 3 - Hit up your local hardware store and pick up all of the lumber and hardware you will need. Or if you are like me, dig through your salvage and scrap for most of it, then pick up what you don't already have.

Clean Up the ImageOpen up the image in your editor of choice. We're going to have to make some changes.1. Turn the saturation all the way down to get a black and white image.2. Adjust the levels for maximum contrast.3. Invert the colors. What you want...
In my code, Digital 3 is connected to a momentary button connected to GND. (It is used to modify the code's behaviour - at startup you can disable or enable various sensors with button presses.)
Analog 3 is the GSR (Galvanic Skin Response) sensor.The two contacts are conductive metal. Normally two fingertips are used to keep touch with the contacts.I placed two copper contacts like so, in spots my index and middle fingertips naturally...
1. The first thing I did after coming up with the idea is to find a way to control 3 sets of 8 leds on each with a minimum amount of wires. I found an article that talked about shift registers and went ahead and ordered a few to try them out. following...
3. I picked up some lexan from home depot and designed the front panel of the flux capacitor. I cut it out on my home made cnc machine and painted the back black. I also cut out a bezel from mdf, sanded and painted grey.
