Appendix B – Deployment Channel Testing
You must perform a Master Reset before you can perform deployment channel testing, see
the Eggtimer Assembly Manual for details.
IMPORTANT: The output channels are designed to be used with some kind of resistive load,
i.e. an igniter, a Christmas Tree light bulb, etc. NEVER CONNECT A SIMPLE PIECE OF
WIRE ACROSS THE DEPLOYMENT TERMINALS TO PERFORM A DEPLOYMENT
TEST. If you do, and your battery is capable of sourcing more than 8A of current (i.e. a LiPo
battery) you may damage the Eggtimer’s output transistors.
Testing with the Eggfinder LCD Receiver
One nice thing about have an Eggfinder LCD receiver is that you can remotely test the
deployment channels, you don’t need to be close to the rocket when you do it. This allows you
to do a full deployment test, including your pyrotechnic charge, safely away from the rocket.
SAFETY WARNING: ALWAYS TEST IGNITERS OUTDOORS, WITH A SUITABLE
DISTANCE BETWEEN YOU AND THE IGNITER (AT LEAST 5 FEET). If YOU ARE
TESTING WITH A PYROTECHNIC LOAD, WE RECOMMEND AT LEAST 10 FEET
OF DISTANCE BETWEEN YOU AND THE ROCKET, AND NEVER STAND
IMMEDIATELY IN FRONT OR BEHIND THE ROCKET.
To perform a deployment test, prepare the igniter and charge and the battery. Make sure that the
deployment power and the Eggtimer TRS power are turned off! Mount your rocket on a suitable
fixture so that it won’t move as the nose cone, parachute, and protector are ejected by the
deployment charge.
Turn on the Eggfinder GPS, and immediately turn on your Eggfinder LCD receiver to pair it up.
When you get the pairing screen, turn on the deployment power, then step safely away from the
rocket… we recommend at least 30 feet.
Press the button, then cycle through the screens until you get the following screen:
Hold the button for at least 1 second, then release it. You will see:
