Things I've Built

RF projects

I helped design and build circularly polarized (as well as dipole) HF antennas as well as an ELF detector using a lock-in amplifier. https://alaskit.net is a startup I like to work with.

HEGduino

I produced an ESP32 kit for a neat little biofeedback device that lets you monitor and control the blood flow in specific regions of your brain. https://crowdsupply.com/alaskit/hegduino
