Ray Guns

I've got a couple of ray guns that I made from old candlesticks and such, I don't have process pics but was thinking I'd make an instructable for them (or at least one of them). Anybody else got any or made any, I would love to see them and I think others would too.

Fake X-RAY Exhibit

Hello all I wanted to know if anyone has an idea about cameras that have an X-RAY application. I am building a kids hospital for a museum and we want a play X-RAY machine. I thought that there may be a camera with an app that you can take a picture of someones hand, leg, face ect. and then it would alter the photo to look like a bone visible photo. Any ideas? Thanks

ion ray gun

Remeber a while ago I said I wanted to make some cool high voltage weapon in the shape of a gun? Well I've dicided to make an ion ray gun! The only problem is that I don't want to pay for plans (that's just not right, half the time they probably jip you). The closest thing I've found is this:http://www.freeinfosociety.com/site.php?postnum=250but that doesn't help me with saftey procosions (sorry, having a bad spelling day).Basically I need help for the schematics and the safe way to build and handle one. I don't want a wimpy one either, I want a medium power one, like do stuff from 10-20 feet or something like that.Oh and if possible, skip extra circuits by using something like this:http://www.goldmine-elec-products.com/prodinfo.asp?number=G9695I also don't mind making voltage multiplier circuits.If everything works I'll make an instructable out of it!Oh, and tech-king, you can use the sign now.

X-Ray Polaroids

Here's a good use of old radioactive material. Use it to expose Polaroid film to create some ghostly images of old items.Why would anyone do this? The author puts it out there pretty clearly:For some time I've been fascinated with the idea of reproducing these types of images in my home lab without great cost and with relative safety. As a collector of radioactive minerals and other ephemera, I decided that I wanted to use naturally radioactive materials as the source for my 'penetrating rays' rather than an amateur electrical x-ray machine setup.Polaroid film is readily available and it develops itself. However, a workable technique needed to be developed. How to expose the film for hours or days without the need for absolute darkness? How would I develop the film reliably after an exposure was made?The answer came from Kevin Clark of the Yahoo group, "GeigerCounterEnthusiasts". It was here that Clark explained his simple, yet reliable, technique for creating inexpensive Polaradiographs.Items you'll need: 1. A Polaroid SX-70, Type 600, or Spectra camera 2. A package of unexposed Type 600 or Spectra Polaroid film 3. One metal cookie tin at least six inches in diameter 4. A few sheets/roll of aluminum foil 5. Radioactive materialThat radioactive material can include:- Old, unused lantern mantles- Salt substitute or certain rock salts (Potassium Chloride)- Vaseline glass (plates, cups, or marbles)- Fiestaware plates and dishes- Welding rods- Old camera lens or vintage prescription eyeglasses (look for yellowed or browned optical glass)- Uranium ores and minerals- Exempt, unlicensed radioactive calibration sources- Radium containing clocks, watch hands, compasses, dials, and gauges- Tritium gunsights and keychain fobsCheck out the site itself for the full story. It's a good read with plenty of information about the history of x-ray photography.via Neatorama

Ray Bradbury has died.

Ray Bradbury, prolific and influential SF author, has died aged 91. His keynote book was "Fahrenheit 451", which portrayed a future world in which books are illegal, and for many years Bradbury refused to allow his books to be published in anything but paper formats (although he was eventually bullied into giving permission for digital publishing, Amazon UK does not currently sell any of his works for the Kindle). But, if you've never read any of his work, I'd start with Something Wicked This Way Comes*.  It's not SF, but it is powerful and disturbing (especially to a ten year old voracious reader).

57-Storey Death ray

Concave, polished, and 57 stories tall - the Vdara Hotel in Las Vagas could be the world's largest death ray... Reports are cropping up around the web that the smooth curved surface of the hotel focuses the Sun's rays into a patch around 10 feet across in the pool area, soon after noon. Fortunately, the glass disperses around 70% of the solar energy falling on it, otherwise lawyer Bill Pintas might not be here to tell the tale; After a brief dip in the hotel pool, Pintas was sunning on a recliner. He was on his stomach, relaxed, eyes closed. But suddenly, the lawyer became so uncomfortably hot that he leaped up to move. He tried to put on his flip-flop sandals but, inexplicably, they were too hot to touch. So he ran barefoot to the shade. "I was effectively being cooked," Pintas said. "I started running as fast as I could without looking like a lunatic." Then he smelled an odor, and realized it was coming from his head, where a bit of hair had been scorched. It was about 12:20 p.m., as best Pintas can recall. The hot-spot, which sweeps the entire pool area during the day, spikes at least 20 degrees above ambient temperatures, and has been seen to melt plastic bags and cups (made of plastics which melt at around 70°C (160F). Other guests, including newspaper reviewers, have also observed the burning beam. The hotel management doesn't call it a "death ray", they prefer the more friendly distinction "solar convergence phenomenon". Gordon Absher, a spokesman for MGM Mirage says the hotel is addressing the problem, and comments, "Because of the curved, concave shape of that hotel, they sometimes get isolated pockets of high temperatures." ---------------------------------- Never mind dispersing the light - get those windows polished up, and let's see how many lawyers a fifty seven storey burning glass can really deal with!

Observing "weather" (stratospheric temp.) with cosmic rays

An article in New Scientist reports on an analysis of cosmic ray muon data from the MINOS underground detector, which correlates with "sudden" (24-hour timescale) temperature changes in the stratosphere. The original article in Geophysical Research Letters gives you a good flavor for how this kind of analysis is actually done, and written up for publication. The figure below (Figure 3 of the article) shows the beautiful correlation between the temperature (5-day running average in blue) as measured by sounding balloons, and the muon rate in MINOS (also 5-day running average, red band with uncertainties). The alignment of the two curves is obviously not known a priori. The exact numerical calibration between muon counts (red, right scale) and temperature (blue, left scale) is a fitted output of the analysis, not an input.To me, it's just kind of neat that particle physics can relate so sharply to some "real world" large-scale properties.

How to build a ray box to use for a set of refractions/reflections? Answered

I would like to make a 'solid' ray box (not out of cardboard!), preferably with more than one slot, and shine the rays from it to a set of mirrors, prisms, and all different kinds of reflective/refractive materials. The light would bounce off quite a few medias so I imagine it needs to be quite strong, but again, how strong? I know I need a fresnel lense in order to make the rays coming out of my ray box parallel but what is the rule, what distance does the lense need to be from the source of light, and does it depend on the size and strength of the light?

X-Ray your finger with stickytape!

Scientists have discovered the cheapest source of potentially-useful X-rays.Peeling sticky tape emits X-rays strong enough to scan a human finger, a remarkable experiment has shown.US researchers used a motorised peeling machine to unwind a roll of Scotch tape at a rate of 3cm per second.By placing their apparatus in a vacuum, they measured X-rays strong enough to X-ray a human digit, according to a report in Nature journal.It is well known that unwinding sticky tape produces sparks of light that can be seen in the dark by the naked eye.This phenomenon, known as "triboluminescence", is produced by the friction generated when two surfaces rub against each other.The study, by Carlos Camara and Juan Escobar, of the University of California, Los Angeles, USA, provides evidence for the phenomenon, which was first observed more than 50 years ago.
