Hello!

My name is Hayden Ehler

I'm an electrical engineering student with experience in business management, leadership, and internetworking.

Quick Links

FPGA Beamformer

Using the Altera DE2 FPGA development board, I am currently developing an 8-transducer beamformer capable of generating an A-line for ultrasound imaging. This is a project for a class in IC design and fabrication.

Capstone Project

Iridium/GNSS

Transceiver

- Designed PCB and wrote firmware for Iridium 9603n
- Supercapacitors and charging circuit for load balancing
- Antenna switch for shared Iridium/GNSS
- Loosely based on Artemis Global Tracker

Revision 2

Revision 1

Student-Led Engineering

Design Teams

As part of my involvement in the Dalhousie Space Systems (DSS) ATOM CubeSat project, I designed, assembled, and validated multiple PCBs that will control the attitude of the satellite when in orbit.

CubeSpace ADCS Health Acceptance Check

Read about my experience with the latest generation of COTS ADCS systems. This model will be used for MANTIS, the third-generation DSS CubeSat.
