Toiletron
Primary Design Goals:
- Simple Through-hole Design: Easy to build for amateurs and the fact that this device may require the cooperation of the organization's telecom administrator. He/she will probably want one too when you explain what it does.
- DTMF Dialer: This will allow multiple devices to share the same analog voice line versus dedicating a hot dial line for each user. This can also allow one to hijack a pots line if you want to be sneaky.
- One Press Activation: You shouldn't have to think too hard when you really don't want to deal with random office garbage.
Secondary Design Goals:
- Use POTS loop current rather than an external power supply.
- Easy end user number reprogramming. (dial-in reprogramming or configuration switches).
- Pedal version so that you can panic dial with both hand visible to avoid suspicion.
