From: "Eric M. Jones" For anyone who thought HS or college physics was incomprehensible, and apropos of this group, look at this page: http://amasci.com/wing/airgif2.html For those who want to experience physics without math, Buy a few copies of "Conceptual Physics" by Paul Hewitt. It is great to start students off on the right track. Not too late for Xmas. There's lots of great stuff on the Internet. I write on subjects related to physics on "Perihelion Science Fiction". Perihelion Design is the name of my website. Yes, I named them both...but it's a long story. I should be driving rivets.... -------- Eric M.

Highly recommended ESPECIALLY for grandparents looking for interesting things to do with grandchildren not completely distracted/disoriented by the chaotic input of 'data' in their daily lives.

Needless to say, they shipped from China and they took about 2 1/2 weeks to arrive here. The LED string is supposed to be weatherproof and it has an adhesive backing with peel-off cover/protector. One end is provided with red/black pigtails for connection to the power pack/dimmer: The string may be cut to length every three LEDs. You can see the scissor symbols where cutting is permitted. Also available are connectors to attach to the end of the cut-off section of string to allow them to be used. I have a pack of those connectors on order but they have not arrived yet. The connection to the power pack/dimmer is simple and I connected the power pack to my power supply for testing. The power pack/dimmer is for use with 12v-28v DC. I set my power supply to 12v to check it out. With the power pack/dimmer set to minimum power there was a surprising output of light with a current draw of 0.1A. With the dimmer turned to max brightness the light output was impressive and only 1.5A of current draw. My initial plans for the string were to backlight the fuel sight gage which I believe will work quite well. But that will only take about 1 - 1.5 meters of string. I=92m thinking about running the remainder inside the center tunnel of the Europa for lighting when I=92m working inside there. I think my biggest problem will be mounting that funky, big power pack/dimmer in an unobtrusive location. These LED strings are available in single color red, green or blue sets as well as white. They are also available in multi-color LED=92s with programmable power supply to do visually interesting things with the string. I haven=92t gotten up the courage to tackle the multi-color string yet. And the prices are very affordable for the tinkerer. The mind boggles at the potential interior and exterior uses of these lights! Blue skies & tailwinds, Bob Borger Europa XS Tri, Rotax 914, Airmaster C/S Prop.

There are ample differences in the kind you can buy (quality etc.) Cheers Werner do not archive > The mind boggles at the potential interior and exterior uses of these > lights! ________________________________ Message 9 _____________________________________ Time: 02:33:06 PM PST US From: "Robert L.

One end is provided with red/black pigtails for >connection to the power pack/dimmer: This is the same class of lighting strip I mentioned about a year ago. I'm using these for under the cabinet, over the counter lighting in the kitchen. I'll be using them for general room illumination in the upgraded kitchen and a bathroom project. Eric has a dimmer suited to these lights in airplanes. http://tinyurl.com/mmuvz7z His design allows customizing min-max voltage to accommodate the unique dimming nature of series-string leds. Your max dim is about 7 volts while max bright is full bore. I'm planning on putting segments of these strips in polycarbonate tubing for gee-whiz and general work light on Dr. Dee and Son Zach's cotton candy and shaved ice concessions. These are exceedingly versatile products. The only shortcoming I've identified so far is the grade of peel-n-stick adhesive supplied. DOES NOT stay put with temperature effects outdoors and in vehicles. Get some 3M mounting tape of appropriate width and use it to attach these strips down in a high temperature environment.

The weak point is the cheapy dimmer that is very noisy (electrically) if you are going to use it in the aircraft. There are better ways to control these strings. I am going to make some "ultralight" versions with non-weatherproof and spray with a plastic film used on circuit boards. You should try playing with the multicolor and start with a cheap controller it's no more than three slings together. My wife loves it! 5 meters in the bathroom and shower with a cheap and simple controller "making waves" with colors. You get all from slow ambient-hypno-color-fading to total alien-disco-flashing!
