Both versions have the schematic attached. However, the resolution of the schematic isn`t that great. I would recommend saving the image above or downloading it from HERE to ensure you can see everything accurately. There isn`t an easy way to shield yourself from x-ray scanning, but you can build an inexpensive detector to notify you of an x-ray s

ource operating in the area. Zinc Sulfide is the stuff that makes the ghostly green glow in the dark products that activate after being exposed to light. It also glows when exposed to x-rays and gamma rays. After it is good and dry use electrical tape or shrink wrap to cover the detector on the photo transistor. Visible light will not penetrate and activate the device if the detector is completely covered. X-rays and gamma rays will and they will cause the ZnS powder to glow, thus activating the photo transistor. To test your device, bring it near an old tube style television. The older the better, especially if it is black and white. TVs using a Cathode Ray Tube emit x-rays, the older TVs more than the newer ones. You could also use a CRT style computer monitor. VR1 in the circuit adjusts circuit sensitivity, so you may need to adjust it. Ideally, you want it as sensitive as possible. Janet Napolitano oversees what is equal to the worst elements Wehrmacht Germany ever produced. Homeland Security has increased its reach and depth to nearly every part of what was once a free America. Now she seeks to bug websites, social networking sites, your text messages, your phone calls, your e-mails and anything else she can get her filthy paws on. They want to force encryption program authors to include back doors. This generator is suitable for use as a wind generator or as a hydro generator. Both uses are covered in this in-depth...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
