Gamma Isotope "Music Box" fun project with DIY Spectrometry Driver kit

Just for fun – Isotope “Music Box”. I used my DIY Spectrometry Driver with BICRON probe. Pulses comes from buffer amplifier into Analog to Digital converter in PIC12F683 and then it played through miniature audio amplifier. Analog to Digital converter in microcontroller is 10 bit ADC. It’s not full spectrometry analyze software, but it good enough to catch single pulses and convert it into sound. Anyway the sound frequency we can hear is slow and needs at least 10ms for each click, so many pulses are lost until we will play one pulse in speaker.
The frequency of clicks depends on the energy – lower energy gets lower frequency and higher energy gets higher sound frequency.

Later I updated ADC software to make the sound harmonized. You can check this latest video to hear how it sounds.
