Meter Design based on arduino ATmega2560 Removable payload bays and sleds Arming switches Components will be friction fitted and sanded for precision fit. Integration is planned for February 16 February 22 Internal Friction fitted and secured with pins/screws Aluminum rod for camera rotation Mounts for all payload components Quick-links for parachute connections External 0.25 rail beads AT-2B transmitter for tracking XBee Pro 900 transmitter for data Electronics arming switch Simulations indicate that the payload will reach an altitude near the 1 mile mark at subsonic speeds Recovery system will have a drogue and main chute and be fully recoverable and reusable The dual deployment recovery system requires further testing to guarantee proper altimeter function Full-scale construction has commenced Education outreach is ongoing Thank you.
