Exterior Wifi Super Antenna

I need to build a dish for a friend so he can get WiFi from about 200 meters. I have several dishes to work with my problem is the antenna will be at least 30 feet from the computer. I will use this linksys usb  i would like input on the idea of a usb to cat 5 to stretch the usb cable? should i power the linksys from a powered hub ? the build will be posted on instructables when done and i will give credit due. my parabolic gets about a 14 db increase from a WiFi usb thumb it just puts the thumb into the sweet spot of the dish and is not for the outdoors. I an open to any and all suggestions tomorrow i will post what my db are from the site .

Looking for more info on dish actuator

I received a free actuator from my friends cottage. 11 years ago it use to angle a 8ft dish. It was removed some time ago, and the label is fully off. The bottom says its a saginaw performance pak actuator, aka PPA, and it has a 24" arm. I was trying to find more information on it, and all I can find is that it can be heavy, regular, or light, 600-1,500 pounds dynamic linear. Anyone have one or any ideas? I cant find a model number on the case cuz it faded, but the motor says 7821645 or 1821645. Either way I found a tiny chart listing models but not that one. similar to that one there. I just want to find out how much force it has. Most I done so far to test it works aftter 11 years of rusting on the main shaft (the moving piston is fine) is sit on a box. It manage to push me with no change in motor sound. Any more details? Please ask!

Battery powered outdoor water dish heater

I have 3 dogs who are kept outside at our Pennsylvania home.  None of the shelters are near an electric source. With winter freezing temperatures on the way, is there a way to keep their water dishes from freezing, especially overnight?   Is there a way I can use one of the electric dog dish heaters to run, say on a battery without it costing an arm and a leg (I have 3 dogs!!)??  I'd buy the dishes at a pet supply place (see site below) for about $30, but running electricity to their kennels is not possible.  Any advice?;?utm_source=nextag&utm;_medium=cse

Tips to mod a single basin kitchen sink into a double-basin?

Greetings All, I have a largish single basin sink in my kitchen. I don't have a dishwasher, and I find that its easiest to do dishes with two basins - one for washing, the other for rinsing. I beleve this is also an efficient use of water and energy (to heat the water). Since I rent, I can't replace the sink itself, which is the most direct solution. I have tried using various tubs and buckets in the sink. To date I haven't found any that work well. Usually the geometry is all wrong. The bucket is either too small to be useful, or too big to fit in the sink. Or, the shape of the bucket or tub makes an awkward fit, and won't lie flat, etc etc. My dream solution would be to make a custom tub whose outer dimensions match exactly one half of the existing basin. Ideally out of pliable silicone. Is this feasible? THanks!

How do you clean a dish washer?

I was wondering can any one give me pointers on this? Lately our dish washer is leaving spots on our dishes, glasses and est. I figure it is a build up of minerals in the spray and drainage holes of our poor dish washer since our house water system does have hard water. Even though we regularly use things like Jet dry to supplement the dish washing there comes a time where even that is not good enough to keep away crusty minerals. We had this dish washer for years now and never have issues until now. I plan on using a product like CLR in the dish washer but I'm not sure what to do next. Do I just pour the whole bottle of the product in the machine or do you pour it in a certain place? After I do imagine that I would have to let it sit in there and then run a few cycles? What do you guys suggest? Thanks for your input.  :)

I want to model rays of light bouncing off a parabolic dish with technical drawing, How do I do it?

Basically I want to model the sunlight as it bounces from both a parabolic and a compound parabolic dish. I want just to use technical drawing. It is no problem to model if the dish is pointed straight at the sun but I want to model the rays if the dish is NOT pointed at the sun. On a curve, I will gestimate a tangent to an arc and light bouncing off goes off it at the same angle as it hits it. NO problem it the light arrives parallel to the plane of the dish but most of it will not arrive like this. How do I do it? Just with elevation plan and sideviews and sections through the dish.Thanks Brian It is in relation to

Take a look at this! 2 parabolic troughs combined to make a point focus!

Http:// is from a Swedish mathematician.He bounces light from one trough to the other to produce the point of light. Even if it is not as efficient as a parabolic dish (2 reflections instead of 1) it must be easier!He is just curving sheet material. I have made parabolic dishes and it is really hard to be exact enough and it is really hard to get the reflective material to go onto the dish without crinkling. So under "real life" amateur conditions, his apparatus is likely to be as efficient as a home made parabolic dish!He has more info and he has pdf files to download too.Great Idea. Hope someone makes an instructable.Brian White

Sandia, Stirling Energy Systems set new world record for solar-to-grid conversion efficiency

31.25 percent efficiency rate topples 1984 recordALBUQUERQUE, N.M. --On a perfect New Mexico winter day -- with the sky almost 10 percent brighter than usual -- Sandia National Laboratories and Stirling Energy Systems (SES) set a new solar-to-grid system conversion efficiency record by achieving a 31.25 percent net efficiency rate. The old 1984 record of 29.4 percent was toppled Jan. 31 on SES's "Serial #3" solar dish Stirling system at Sandia's National Solar Thermal Test Facility.The conversion efficiency is calculated by measuring the net energy delivered to the grid and dividing it by the solar energy hitting the dish mirrors. Auxiliary loads, such as water pumps, computers and tracking motors, are accounted for in the net power measurement."Gaining two whole points of conversion efficiency in this type of system is phenomenal," says Bruce Osborn, SES president and CEO. "This is a significant advancement that takes our dish engine systems well beyond the capacities of any other solar dish collectors and one step closer to commercializing an affordable system."Serial #3 was erected in May 2005 as part of a prototype six-dish model power plant at the Solar Thermal Test Facility that produces up to 150 kilowatts (kW) of grid-ready electrical power during the day. Each dish unit consists of 82 mirrors formed in a dish shape to focus the light to an intense beam.The solar dish generates electricity by focusing the sun's rays onto a receiver, which transmits the heat energy to a Stirling engine. The engine is a sealed system filled with hydrogen. As the gas heats and cools, its pressure rises and falls. The change in pressure drives the pistons inside the engine, producing mechanical power, which in turn drives a generator and makes electricity.More here:

Quick and dirty parabolic dish solar concentrator design!

I do not have one.       I was hoping YOU could help me make a quick choice!   Basically I want to go to the store, buy an 8 by 4 corugated plastic sheet, cut it in petals, stick aluminum kitchen  foil to it (as few wrinkles as possible) and have as rigid a parabolic HALF dish as possible.   Then I mount it in my equatorial mount frame and test it.   It gets a bit harder because the dish is not exactly a half. Some extends a bit past the center of the dish. Here are some of the issues and choices.  Do you cut along the corrugations or across them? Do you do petals radiating out from the center  or is it better to do the thing with cones? Like in the picture in the link Cones might have a problem due to the corrugations not being in line with the shape that I make. so it might warp in strange ways. Is there an alternative to the corrugated sign plastic sheet? BUT they might work because I can guesstimate a not perfectly round dish more easily than with petals.. I think that something with a focus about 6 inches wide would be sufficient for me. It has to be rigid and light as can be too.   What can I use as umbrella splines to make it keep its shape? Thoughts and suggestions would be greatly appreciated. I might have a day off tomorrow so get those suggestions in quick as you can! Thanks Brian

Software for designing solar cookers and reflectors for solar panels

Parabolic dishes are favoured because they are "perfect". Unfortunately they are only perfect if they are kept constantly pointed at the sun. In practice this is very hard to do. A better shape would maintain good reflection of the sunlight for a long time without moving the dish.I think I have found useful easy software to help with this design work. It is called art of illusion and you can see my first results and a downloadable scene file to help you get started on step 12 of this instructable White

Pre-peeled versus fresh garlic?

In what dishes can you tell the difference between pre-peeled and fresh garlic. How about Chinese versus Californian pre-peeled garlic?If you can tell the difference, how can you be sure? I love garlic, and use a lot of it. I'll toss a handful of chopped cloves into almost any savory dish that involves a sauteing step. Using so much and being pressed for time, I primarily buy Californian pre-peeled garlic, and chop it right before I use it. I'm curious if you judge pre-peeled garlic to be less flavorful, and if so, can that flavor be returned by an increase in total garlic or if there are fleeting compounds that escape as soon as the garlic is peeled.Another thing I've noticed is that I need to be careful when I make dishes where I food-process the garlic to mince it. I've ruined a curry or two by using food-processed fresh turmeric, fresh peppers, and pre-peeled garlic that smelled fine but had probably spent a week in the fridge. In the finished dish, the garlic contributed a pretty nasty "raw vegetal" taste. Similarly, Christy once food-processed and sauteed some onions and older pre-peeled garlic only to have the whole mixture turn blue and taste horrible. discoloration is due to pigments that form between sulfur compounds in garlic and amino acids. When the garlic tissue is disrupted, as happens in processing, an enzyme is liberated and reacts with it to form thiosulfinates compounds that then react with the natural amino acids in the garlic to form blue pigments. The age of garlic determines how much isoalliin there is in the first place, and the nature of the processing determines how much enzyme is liberated.The blue color apparently shouldn't harm the taste, so it would be neat to develop a dish that naturally turned blue using this reaction while still tasting great.

I want to delete my kyoto trough insturctable but it was in a contest so it will not let me.

It was in a contest and it seems you cannot delete stuff that was entered in a contest. I made the instructable to attract smarter people than me to the problem of unattended concentrated  solar cooking by combining 2 reflective  troughs  (to mimic a dish). (Troughs are easy to make (bent in one direction). while dishes are bent in 2 planes so they really hard to make without wrinkles on the reflector material. Nobody got attracted so I guess the idea is dead. Anyway, for me personally,  it was  a stepping stone on the way to  the clam shaped solar reflector. So it was useful but it is history now. So is there any way to delete it or substitute another thing in its place? Thank you Brian White

Can combined troughs replace parabolic dishes for amateur solar cooking?

I have being doing limited testing of the combined trough shown below and it seems to work as expected. I used a 4ft by 8 ft piece of corrugated plastic for the big trough (too wide but I was reluctant to cut it). Compared to dishes, this was incredibly easy to make and actually gives more reliable concentration over a longer time period. Would anyone like to try it on tiny demo scale? (I mean something tiny made with 1ft by 2 ft paper perhaps) see if you can make a panel cooker with the design as a template? I think it will work with hemisphere curve, or parabolic curve, any curve or panel cooker shape that shines the light on a cooking vessel. Key points. 1 The troughs must be curved in directions that are at right angles to each other. 2 the long primary collector trough must be in line with the path of the sun.And thats basically it! The primary trough concentrates light in one plane and the secondary trough (the little wings round the red pot) concentrate it in the other plane. I then tried to get software to show if it was any good and It seems to show that it would cook for significantly longer than a parabolic dish. But the software showed that it was not as good as I had hoped. From running the software (art of illusion) I came up with the kyoto trough as a possible solution.The kyoto trough is a trough made by taking 2 halves of a parabolic trough and twisting them a little inwards roung the focus. This can focus all the light between the focal line and the bottom of the trough for a time period coresponding to the angle of twist. 15 degrees of twist coresponds to one hour. That is a really useful property because it confers reliability. The next part of the kyoto trough can just be an ordinary parabolic trough to do a final concentrationof the light onto the cooking pot. Well 2 small troughs to deal with 2 streams of light going towards the cooking pot from either side of the trough. Are any mathematicians interested in resolving the troughs into a Kyoto Dish? which would give much longer cook times than a parabolic dish.Brian

Solar reflector mounted on part of an office chair, might give people some ideas.

Http:// is a video that shows a solar reflector that I made from mylar and an 8 by 4 sheet of corrugated plastic. I approximated a parabolic dish by cutting it to  make cones. I used bamboo to make it more sturdy. (Still needs more bamboo). It is on a stand made from an old office chair.  I intend to line up the mount properly and put it on equatorial mount but that will take a while. It might be weeks before I have time to test the thing so here it is for now.   I am slow at the experiment stuff. The dish started last september! And it took me that long to figure out how to keep the shape resonably tight. So here it is at this moment. It will change a lot before it is finished but no reason not to show the current state of the project. Brian

Fabric cover for flash modifier - what's your idea?

After doing extensive web searches it is clear that no one makes a flash modifier / photo light reflector that meets my needs. The unit I have in mind would be the general shape of a small photo umbrella (about 16" in diameter), but it would function like a beauty dish. I want it to be collapsible and compact, yet durable enough to withstand many location shooting sessions. I have used the following basic frame construction technique on other projects and know that it will work for this one - I will solder together a reinforced (beauty dish shaped) frame structure that will be made out of small diameter brass welding rod and then add connection bracketing that will allow the photo reflector to be dismantled for transport. During my initial planning stages I thought I would just sew up a fabric cover (white on the inside, black on the outside) so that it would wrap around the frame on both sides. But then I realized that this was a very complex sewing job and that an easier method of covering this dish shaped frame might be to use heat shrinkable RC aircraft covering fabric. When I researched these materials on the web I discovered that they were very thin (just what you would want on a small airplane) and really wouldn't take any degree of wear and tear like you might expect during a photo shoot. So here's the question - what kind of fabric covering would be ideal for this photo reflector? It needs to be strong, lightweight, very flexible so that it can be molded around the contours of the reflectors frame and it should be paintable - white on the inside and black on the outside. Thanks for your suggestions

Feedback Can someone test my Instructable "software for solar reflector design"?

I have an instructable about designing better reflectors for solar cookers. (Better than parabolic dishes). Basically you can design your own dish, and compare it to the parabolic dish and other shapes with the software. On step 1 there is a zipped folder for download. It contains an art of illusion scenefile. Art of illusion is the modeling and animation software I used. It is easier to learn than its competitors and it is free. The folder also contains a html file for almost automatic tabulating of your results and comparison with other reflector shapes. I have "starter" jpg images for when you create series of 10 images for comparison. I hope to put in a help html file too but thats all for now. To test it, you do need to download art of illusion too. I know this type of project can be a bit of a pain but with feedback, I can refine it. And where else do you have free tools to test solar reflectors? hope that this will grow. A guy in Finland has already done a rudimentary "sun engine" that will do the shadows from a day as an extension to this project! That could be used to design passive solar houses and to site vegetable and fruit gardens in the best spots. (Depending on the seasons and day length, shadow patterns from trees and houses are very different). This is not something you can imagine just from surveying a site! Anyway, hopefully I will get some input.The instructable has grown and changed a lot as I have improved the scenefile. There are certainly parts that need trimming now. Hopefully I get round to it in the next couple of days. Brian
