I had an idea for a house building process involving the use of line-x, however, i cannot find it's price anywhere, so i would like to know how much does it cost to apply a layer of it on a wall per m2. Also, does it take any special equipment to apply it or just any spray paint gun?

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

Many of you will know about International Talk Like a Pirate Day. Some of you will know that there's a national election in the UK soon. In the UK, Captain Tom has lost a bet, and has to stand for parliament. Why should this interest us as Makers?

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

X-CTU not detecting xBEE?

I am trying to communicate between two xBEEs. one xBee is connected via the xBee explorer shield to COM9 in to my laptop and the other is conncected to the arduino uno via the xBee shield ( ) to COM 17. I am using xBEE Series 2. Now the xCTU detects the xBee connected via the explorer; however it doesnt not detect the one connected via the shield to arduino. It just says Arduino Uni (COM17) in xCTU. and whn I try to rest it it says 'Unable to open com port'. I have moved both the jumpers on the other pins on he USB side, but still no luck. I have tried all the combinations but it doesnt work. Can someone help me with this problem please? :(

Home-X does Mouse Taxidermy

James Powderley's Home-X class had a mouse taxidermy session using my taxidermy Instructables. They made some great mice! Pictures here and here and here. They also learned to knit, solder, and do some chemistry; textbooks include the Cartoon Guides to Chemistry and Physics. Doesn't this sound like awesome fun? Check out the course description:Welcome to the Disruptive Home Economics class at Parsons New School for Design. To the initiated, the class is called Home X. The goal of this class is to expand our ability to make things at home, whether for entertainment, expression or survival. Home X will take us all through the center and to the fringe of what it means to make-it and do-it-yourself. We will start by making or modifying existing DIY and How-to projects and studying the way other makers solve problems and create documentation. Over the course of the semester, we will get hands-on experience researching, designing, documenting and sharing our own DIY projects. We will take a generalist's approach and gain experience with a wide range of mechanical, electrical, computational and chemical processes. We will combine novel tools and materials with common ones and build projects for ourselves as well as tools for others. Along the way, we will also look at the way cultural and historical contexts influence the technologies we make and use, as well as the implications of open source production by the masses. Students will be encouraged to release their work as openly and widely as possible and to experiment with traditional and contagious distribution of their projects.More info hereAs they say in Home-X: D.I.Y till you R.I.P.

How to connect a landline to Mac on OS X?

---The Problem---- I've searched high and low for something that will allow me to connect my normal landline (see links at bottom of post) to my MacBook Pro (2.16GHz core 2 duo, on OS X Snow Leopard).  The landline is my work landline, so I can't change it. I really just want to connect it to my Mac through its "To TEL" port, which according to the manual is for connecting phones in parallel. The minimum I want to be able to do is get audio from the landline to my computer's speakers and audio to it from my computer's speakers. My goal is to be able to work handsfree on my computer while I type. I'm not keen on a headset for the landline because I hate cables and get tangled up while I type. If I get my voice routed through to the phone through the Mac's microphone and sound to come out through my speakers from the caller's voice I'd be jumping for joy. I'd be rocketing for joy if through some way I managed to use an AppleScript I found (see links at bottom of post) to dial out of AddressBook to the landline. That would be tres cool, but that'd be me getting greedy. ----What I've been able to find out (I'm pretty clueless)------ PCs can do this with an RJ11 to USB adapter. There are rumors that the DLink DPH-50U works with OS X with a driver no one can seem to find. Apple stopped making their USB external modems, which didn't cater for voice anyway. I'm willing to buy stuff to make something if I need, although if it comes to writing drivers I'd need a lot of direction. ----The question----- Does anyone have any clever ideas on how to solve the problem? ----Links------ My landline manual: AppleScript to dial from AddressBook:;=10 Most thankful in advance for any ideas!

24 x 24 LED Matrix Project

I would like to share with you all an awesome project and some doubts and questions related to the same. This is a 24 x 24 LED Matrix project taken from here. All the data is taken from the same link. 24×24 LED dot matrix -->   This is pretty old circuit but I found it interesting to describe here. 24×24 LED display is formed by using 9 8×8 Dot LED matrix displays, that are connected to AT90S2313 MCU. MCU scans an indicator lines in series. Special PC program is written which allows drawing images on screen and transfer them via COM port to device. You can send images in series what gives an animation effect.   Circuit is was built using obsolete AT90S2313 MCU which can be replaced by Attiny2313 MCU with minor modifications of firmware. To make program work you event don’t need to connect device to computer COM port. You can store images in other master MCU EEPROM memory Each received byte from UART is immediately sent to 8 LEDs, second byte to next 8 LEDs and so on. Bytes has to be sent one by one without delay. USART is working at 115200 baud, 8bits, no parity. ---------------------------------------------------------------------------------------------------------------------------------- THE PROBLEMS >1>I really dont know if the circuit is good or not tell me if it is going to work. >2>I cant get 8x8 dot matrix displays so i am going to normal leds to a 24x24 one. >3>I have never worked with bus before (the bold red lines in the circuit) so i dont know how to connect it. >4>The schems are segmented i am finding it hard to figure out how to connect some of the segments. >5>Also i need to know how to hook it up to my pc. >6>I have never done programming so i need to know how to program the ic.

Cutting and re-wiring X-mas LED garlands (not strips) Answered

Hi, Has anyone had to deal with cutting LED Christmas garlands into shorter pieces and then rewiring-powering them? What should I keep in mind when doing so? As far as my electrical knowledge goes I should first inspect the voltage which is provided by a standard converter already on a garland and then measure the voltage with the load (garland) on in several spots to determine a single LED voltage drop. Then cut the garland to desired lengths and power it with appropriate converters. Is this right? What I don't understand completely however is the voltage drop. Given that this is a series circuit and the voltage(resistance) sums up - should I add all the single LED drops to find out the total drop and therefore subtract that from my supply voltage to find out the LED working voltage? Oh, and maybe I am simply wrong about the circuit being in series? Thanks! Raitis
