Where can I find white plastic sheeting?

Black or clear will not work, and that's all I can seem to come up with on google. White and black on opposite sides could work, but I can't find the size I need. Speaking of size, I need it to be 16 to 20 feet wide (and similar length, but rolls could be longer); most seem to be 100' for sizes that wide. One other requirement- reinforced sheeting will not work, I will need it to have a smooth surface when I'm done. Thickness matters less, but obviously the thicker the more expensive and I think 4 mL would work fine. What's it for you ask? Sorry, but it's a secret, at least for now.

Price of regular white LED's???

I just came back from my local electronics store and was kind of shocked to find that the price for a white LED is 2 bucks from where I come from, which is about US$ 0.62 each! I was thinking of buying 100 of them which ends up around US$62.00!!! Is that the standard price? It doesn't look like the regular LED, it's somewhat smaller and shorter in size, with a flat head instead of the usual rounded ones. But the price difference is so big! The standard round headed one's are only US$ 0.09 each! But the funny thing is the salesperson told me that round headed LED's DO NOT come in white, only red, yellow and green! But in fact I bought them before from another store but sadly they are out of business now so there's only this other store left in my city. So my point is, is that the standard price at your local store? How much do you pay for a single white regular LED? PS. by 'regular', I mean those with rounded heads and can commonly be found almost everywhere such as toys and decorations. Also I'm not referring to those high powered LED's used in modern flashlights. The pictures below shows the regular LED, and the one which I saw at the local store which has a flat head.

How to make a small round warm white LED light please?

This may have been asked in a different format if so please accept my apologies. I have bought some cheap Tilly/Storm lamps that would normally be filled with parafin and have the materail wick lighted to achieve the glow of the lamp. I would like to replace the liquid based light with a set of warm white leds. I've also bought a small round adhesive/stick on plastic light unit to try and understand how they work. Having opened it think this will suit my needs in the Tilley lamp. Pressure downwards on the top surface of the light unit switches the LEDS on and pressure released switches them off. The power for this light unit is from 3 x AAA batteries. I would like to either make my own 3 LED light unit from parts but what items do i need and where do I get them from or understand how to replace the bright white LEDS in the light unit I've bought  for warm white ones but how do I do this? I believe that the length of the two stalks comming out of an LED indicates + and - but is the longer one +? Also when it comes to the small triangular shaped circuit board on the original how do I tell the + from the -? Any help will be very much appreciated as these Tilley Lamps/Storm Lights would look good in the garden at night as well as inside. Many thanks, Bernard

My mower smoked and won't run? Answered

I was mowing with my push mower (brigs and Stratton) and suddenly it blew out a large amount of white smoke and stuttered to a stop.  Later that day I tried starting it again and it almost started up but it sputtered and filled the area with a plume of white smoke.  Now (a year later) I decided to attempt to get it running again.  I am not sure about taking out the spark plug because I think it may need a torc wrench or something.  I did however check to see if it would still spark one of my spare plugs which it does.  The fuel in it is still the same so I may try draining it and re-filling it.  It smells like gas.  I have heard of water and oil being probable causes, could this be true.  I know that it has mistakenly been filled with the mix of oil/fuel from my chainsaw's can.  I drained it, but could there still be oil in it or something.  Can I pull my spark-plug out with a mere crescent wrench and replace it?

"It Will Be Awesome if They Don't Screw it Up"

Public Knowledge recently published a white paper on 3d printing (see link for downloadable PDF version). It compares low-cost home 3d printing technology with home computing and digital publishing, with specific reference to the possibility of DMCA-style legislation preventing the technology reaching its full potential. In many ways, today’s 3D printing community resembles the personal computing community of the early 1990s. They are a relatively small, technically proficient group, all intrigued by the potential of a great new technology. They tinker with their machines, share their discoveries and creations, and are more focused on what is possible than on what happens after they achieve it. They also benefit from following the personal computer revolution: the connective power of the Internet lets them share, innovate, and communicate much faster than the Homebrew Computer Club could have ever imagined. The personal computer revolution also casts light on some potential pitfalls that may be in store for the growth of 3D printing. When entrenched interests began to understand just how disruptive personal computing could be (especially massively networked personal computing) they organized in Washington, D.C. to protect their incumbent power. Rallying under the banner of combating piracy and theft, these interests pushed through laws like the Digital Millennium Copyright Act (DMCA) that made it harder to use computers in new and innovative ways. In response, the general public learned once-obscure terms like “fair use” and worked hard to defend their ability to discuss, create, and innovate. Unfortunately, this great public awakening came after Congress had already passed its restrictive laws. Of course, computers were not the first time that incumbents welcomed new technologies by attempting to restrict them. The arrival of the printing press resulted in new censorship and licensing laws designed to slow the spread of information. The music industry claimed that home taping would destroy it. And, perhaps most memorably, the movie industry compared the VCR to the Boston Strangler preying on a woman home alone. One of the goals of this whitepaper is to prepare the 3D printing community, and the public at large, before incumbents try to cripple 3D printing with restrictive intellectual property laws. By understanding how intellectual property law relates to 3D printing, and how changes might impact 3D printing’s future, this time we will be ready when incumbents come calling to Congress.   Podcasts and videos on 3d printing.
