10. Photographic example of the implementation of the device

11. Theoretical Parameters

12. Virtues of System (in comparison to standard Pyros)
Safety:
Less sensitive to sparks & electromagnetic spikes
No hazardous temperatures generated or required
Non-instant activation delays
Preparation:
Faster and easier preparation than pyros
Less chance of damaging critical expendable parts (eg. Ematch installation)
Less anxiety for the preparation (once you’re familiarized with it)
Reliability:
No expendable pyrotechnic devices to be connected and installed
Option for thorough ground testing reusable device to reduce or
eliminate the requirement for redundancy
Regulatory:
No hazardous or dangerous or regulated parts required
Potentially less compliance work required for projects/facilities that require stringent requirements for pyrotechnic devices eg, government/defence operated ranges.

13. General Virtues Low power actuation (can operate on 1 AAA battery)
Wide operating voltage range (1.5V – 12V)
1st 2 points renders it directly compatible with all the available flight electronics systems.
Minimal increased footprint from pyro canisters
Modest weight increase for larger rockets
Easy mounting points
High Discharge Rate - Instant Discharge FAIAP
Quick(ish) response time

14. Disadvantages over Standard BP Pyros
Is a larger & heavier unit
Complex device – Higher production costs
