Howdy!

I'm Andy Kong

I'm currently building chargerless.xyz

I like building hardware, collecting and processing signals, analyzing data, and sharing knowledge.
I also enjoy new experiences, training my senses, seeing things I've never seen before, challenging what I believe is possible, and inventing sufficiently advanced technology.

I live in Cambridge, MA, and plan to move to SF in July 2025. Please reach out if you think we'd have a good chat, life is so short
