Photosensors on IC 555 prototype fixed version 2
Photosensors prototype fixed version 2
Originally uploaded by cultured_society2nd
Version one is a lot messy and had bad wire connections, so I decided to make a 2nd proper prototype. The electronic parts are the same as version one thus 100% workable on any audio input and its output.
How it generally work is simply by connecting an audio output source; currently i am adding a mini radio audio output into this experiment. And output connection audio jack to my custom made amplifier.
Why a radio and not other audio output source? I chose a radio because of its random audio transmission thus I am very interested of the low analogue audio resolution audio quality, this will generally enhance the detection of high noise frequencies output to the relay channel card.
This is just a prototype, a new electronic implementations and its design is still in progress.
What Implementations?
Variety of electrolytic capacitors.
The wide range of audio sine frequency varies with different sub-units of microfarads (uF or MFD), nanofarads (nF) or picofarads (pF) ceramic or electrolytic capacitors. The capacitors in the image was all tested including (100pF, 1nF, 10nF, 0.1uF, 1uF, 10uF), the difference was the capability of the capacitors to store and discharge electrical current over time, “pF” High frequency / “nF” Mid frequency / “uF” Low frequency.
IC 555 diagram
The implementation of different caps will be in connection to IC 555 on pin 6. Positive connection of the capacitor will be connected to the pin 6 where electrical threshold will takes place.
Other implementations?
Variety of photo resistors
A variety of photo resistors had been tested on the circuit, with their different sizes too varies with its resistance. Photo resistors acts as a variable resistor when in contact with light and shadow over distance.
With different sizes and types of capacitor/photo resistors will be implemented on a new circuit.
