3W STEREO DIFFERENTIAL INPUT CLASS-D AUDIO AMPLIFIER WITH UP/DOWN VOLUME

The circuit presented here is a 3W stereo audio amplifier with memory UP/DOWN volume control. The project is based on PAM8408 IC from Diode Incorp which is a filter-less class-D amplifier with high SNR and Differential input which helps eliminate noise. Two tactile switches are provided to control the UP/DOWN volume in 32-steps and it will hold the setting […]

BPW34 GAMMA RAY DETECTOR

The usual approach to radiation detection is the use of a Geiger-Müller tube and its high voltage circuit requirements, but during a quick surf through the internet today, I came across this portable and “accurate looking” solution developed by Stefan Wagner, on EasyEDA. Rather than the Geiger Muller tube and its complex circuitry, the project uses a miniature Silicon PIN
