Custom Two-Way Intercom Design
Budget: $750 – $1,500 USD
I'm in need of an electronics engineer who can develop a custom two-way intercom system for a medical pressure tank, for communication with patients. indoor use only. The system should have the following features:
- Allways communication (from inside to outside)
- Push-to-talk from outside to inside (will mute the other direction)
- Ability to mute all together
- Ability to buzz from inside, for the outside speaker (tone generator)
- 2 Condenser Mic Inputs (nice to have: brakeout bypass of Condenser Mic circuit for other microphones)
- 2 Speaker Outputs (50W, per output)
- individual speaker Volume control
- control signals are all 24V with comman GND
- 0-24V PSU
Ideal Skills:
- Electronics Engineering
- Circuit Design
- PCB Design
- Audio Systems
The project should result in a design that is ready for manufacturing. And would like the engineer to be available for follow-up in case any issues arise during manufacturing.
