This image was made using a using a highly modified Scanmax 20 X-Ray mail scanner that I found via eBay (yes, really). I have substantially altered the imaging system; it now comprises a Kodak Lanex fine fluorescent screen and a Nikon D3100 camera, replacing the original high brightness, low resolution screen and video-based image capture and display. The result is a dramatic increase in resolution over the original 1 pixel per mm or so.
Images are further improved by multiple captures post-processed in Registax 6, which does a kind of intelligent averaging to reduce noise and enhance resolution. This image is made from about 12 exposures. There is some residual noise, of course, but it would take several dozen more exposures to make any significant improvement in signal to noise ratio (or resolution).
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
