Engineering Design Experience
SpaceLex - Rover
Electonic Layout and design
SpaceLex is a student club at the University of Kentucky that was competing in the Friends of Rocketry Competition. While I am apart of the Electronics subteam I also assisted the Payload subteam in the electronics design of their autonomous rover RIQ. The drawing of RIQ is by the Payload subteam lead Lucas Stevenson.
RIQ's mission is to deploy on the landing of the rocket in a sandy location and return to the designated point. As a part of
RIQ's mission we have to transmit both GPS location and a live video. We are doing this through using a 5.8 Ghz 1 watt transmitter and we are embedding the GPS location in the audio channel.
SpaceLex - Avionics
Wireless Data - RF design and implementation
SpaceLex is a student club at the University of Kentucky that was competing in NASA Student Launch liftoff division. I am on the electronics subteam as the principal RF designer. This project is ongoing. I have include the two wiring schematics for avionics and payload circuitry courtesy of the electronics subteam lead Paul Breeding. In the interim we have switched to compete in the Friends of Rocketry Competition. The images and explanation text are about the old design for the NASA Student Launch competition.
For the payload we needed to receive commands on the 2 meter amatuer band (144 - 148 Mhz) using Automatic Packet Reporting System protocol. To do this we are using the DRA818V to translate the radio signal to an electrical signal for the Rasperry Pi Pico to decode.
For the avionics we need to transmit the GPS location of the rocket so we know where it is in order to recover it. I decided on using the LoRa on the 900 Mhz band because of the small packet size and long range.
