Discussion Overview
The discussion revolves around determining the minimum power required for a laser torch used in an audio transmitter and receiver setup, specifically utilizing a 2N5777 phototransistor as the receiver. The context includes considerations of range and detection capabilities.
Discussion Character
- Exploratory, Technical explanation, Conceptual clarification
Main Points Raised
- One participant inquires about the minimum power needed for the laser torch based on its application in an audio transmission system.
- Another participant asks for clarification on the range of the laser transmission, suggesting that the distance significantly impacts the required laser strength.
- A participant mentions that if the laser diode is powered sufficiently to be visible, it should be detectable by almost any photodiode at a distance of 100 meters under good conditions.
- One participant suggests that understanding link budgets would be beneficial for this discussion, providing a reference link for further reading.
Areas of Agreement / Disagreement
Participants have not reached a consensus on the minimum power requirement, and multiple views regarding the impact of range on laser strength are present.
Contextual Notes
The discussion does not specify the assumptions regarding environmental conditions or the characteristics of the laser diode being used, which may affect the outcomes.
