Get X-ray intensifying/fluorescent screens from X-ray cassettes used for radiography.
A scintillation probe enclosing the regulated high voltage supply, the signal amplifier, the photomultiplier and the scintillation crystal (NaI). Building a DIY counter for a NaI Scintillation probe. AtMega8 and a bluetooth module for wireless data output. A cheap and easy to build homemade dosimeter with applications in spectroscopy.
Learn to connect a bluetooth module to an ATMega micro controller via the UART serial interface and even further, discover it using a bluetooth enabled Android phone. The 9600bps serial link established, can than be used to exchange data: read sensors or control the robot.
Build a Half Wave Villard Cascade of 28 Stages. That means for 10KV in you get (in theory) 280KV out! An incredible voltage, perfect for physics experiments.
EM-11 is a magic eye tube, used in old radios for tunning. See some schematics on how to use this tube, for some green, fluorescent effects!
A homemade/DIY security system using a webcam, a low power server and a surveillance software.
The DRSB-01 is a simple Geiger Counter device that can be used to detect normal vs. dangerous levels of ionizing radiation (gamma and beta).
See how to build a case for a mini-itx computer board. A lot of processing power in a tiny box.
The CDV700 dosimeter variant 6B (newer) and a few mods to improve functionality: audio connector and bnc connector.
A short review on the Radex RD1706 dosimeter, how good it is, and how can it be compared to other dosimeters, eg. the Terra-P MKS-05.
A variable 0..30V power supply for max 20ampers! See how to handle all the power and build your own reliable lab power supply.
Perseus 3, a 4×4 advanced robot featuring an Atmega8 for sensor interfacing and motor control, and a I-mate SP5 smartphone (200MHz) running Windows Mobile 6.0 as robot’s brain. Small weight, powerful trust, and lots of features including WLAN, Bluetooth, Camera, Speaker, Phone-interface (GPRS, 3G), Microphone (for voice commands) and more.
An article on various high voltage sources. Includes schematics, construction details, high resolution images and videos.
How to make a high voltage capacitor in a few steps. See a video with my 19nF/10kV capacitor, with under 1$ cost.
