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

12x Blu-ray laser built into a Star Trek (TOS) toy phaser, with sound effects!

I know Kipkay did it first, but this is still awesomely awesomeful :-)  I saw this on MAKE's blog; the original posting is from Jay at Hack'N'Mod.  Using a 12x Blu-ray laser (405nm) running at 465 mW, this has enough power to blind you without eye protection.  It's got a front focus with a properly styled ST:TOS nosecone, and two different selectable sound effects.  Jay's writeup is a complete tutorial for building your own.

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). (*Other retailers are available.)

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.

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!

Violet Voltage?

Every so often, I see "violet ray" electrotherapy devices come up on ebay. They often sell for silly money, but occasionally one will sell for only a few pounds.Originally quack medical devices, they seem to operate in a similar manner to a plasma globe (gas discharges, high voltages). Does anybody know how they work? Is it worth getting hold of one to rip the innards out to get at the high-voltage supply?(Yes, I know they have "adult uses", but, really, it is the innards I'm talking about)

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.

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.

Well, who here doesn't think that x-rays look cool? I personally digg them.So check out these cool designer x-ray lamps! Engadget informs us that, Unfortunately, these lampshade / lights aren't yet available to purchase -- another dream dashed by cruel reality.I however say we will not miss out! so, i think if someone was to get a picture of a bulb, put it through photoshop to make it look like an x-ray, print it out on some paper, stick inside a custom light enclosure, and there you go. A fancy x-ray light.

Trigger Switch For Ray Gun

Greetings Space Cadets! I need help figuring out what sort of switch to use to activate the  thermo-nuclear disruptor beam of the ray gun I'm building out of a busted battery powered drill, a smoke alarm and a battery. Bet you didn't know this combination of junk is dangerous in the wrong hands? I need a switch that will work with DC current and switch on the circuit when pressed but not stay on.  Like a primitive projectile firing pistol of the 21st century this ray gun should only fire once when the power switch is pressed and not stay on continuously. Any suggestions? And yes, I'll post an 'ible when I get it done. Thanks!

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 tohttps://www.instructables.com/id/Compound_parabolic_dish_making_a_template_with_te/

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

Solar Powered Dehumidifier Help

Hey guys. My dad, my brother and I have been pondering the idea of a solar-powered de-humidifier. So, it would charge using the sun's rays, and then use its power in the dehumidifier. This is something that could be used in parts of Africa with 100% humidity, and not alot of water. It is the perfect tool for anyone to use to obtain fresh water, by harnessing the sun's rays. We have a dehumidifier, and we really want to make it Solar Powered. We just need help in the way to power it.Would we charge a rechargable battery using the Solar Rays, or would we run it on solar power alone. The solar panel that I have been looking at is the Sunforce 50022 5 Watt Solar Battery Trickle Charger. Do you think that that Solar Panel is good enough? It is 5 Watts, so how would we connect it to our dehumidifier? This was the solar panel in the most recent PopSci used in the How 2.0 section. It is used to charge personal electronics. Thanks in advance.

Carbon Button Lamp

The Nikola Tesla group forum is asking for new projects, so I'm posting this as a suggestion. I would love to build it myself, but I lack the tools and money. This is my first contribution to Instructables, so please comment constructively.Nikola Tesla invented the Carbon Button lamp as a kind of incandescent light, because Thomas Edison banned him from using his incandescent filament bulbs. Nikola later discovered that versions of it could also be used in wireless, trans-Atlantic telegraphy, and to investigate what we now call x rays. In fact, he even used the lamp (or something similar to it) to take x-ray photographs, 8 years before Wilhelm Rotgen discovered them.For this reason, I must warn you: this device may possibly generate x rays. I am not responsible for any harm of any kind that may or may not result from re-creating this interesting device.There are phosphors that you can buy that will absorb x rays and re-emit them as visible light. I recommend that you coat the bulb with it until you know for sure that the x rays aren't strong enough to hurt you, or if makes x rays at all. Mixing it with a phosphor made for uv light wouldn't hurt either.Theory of Operation:The bulb is powered by a Tesla Coil, or other source of high voltage, high frequency current, such as a driver for a plasma globe (actually, the modern plasma globe is descended from this kind of technology!)When the power is turned on, electricity bombards the carbon button. Because carbon isn't the best conductor, this causes the button to heat and release electrons into the bulb's vacuum (the technical name for this is "thermionic emission," or the "Edison effect") . These electrons, in turn, excite the remaining air molecules and cause them to create visible light. This is strikingly similar to how fluorescent lamps work!Supposedly, the bulb should shine 10 times brighter than an incandescent bulb.(Note that the excitation of the air molecules, not the incandescence of the button, is actually the main source of light from the bulb.)If anyone decides to build it, please post an instructable showing the steps and finished product. I suggest you get started by reading the patent, number 514,170. You may also want to read part of Tesla's lecture, "Experiments with Alternate Currents of High Potential and High Frequency."To anyone who will attempt this, I wish you good luck!Patent: http://www.google.com/patents?id=UpldAAAAEBAJ&pg;=PA1&dq;=514,170+tesla&source;=gbs_selected_pages&cad;=0_1Lecture: http://www.tfcbooks.com/tesla/1892-02-03.htmQuestions:What can one use for the carbon button?Could one use a modern, hollowed-out light bulb for this? (I would think there would be some problems with sealing the globe, and with the stem.)Edit: I recently found the third picture in Tesla's Colorado Springs notes and his "apparatus for the utilization of radiant energy" patent. It must be the single-electrode x ray tube I was talking about before...
