Profile

I bought a Tesla Model X in 2023 and kept staring at the 17-inch display sitting idle while I worked on my 14-inch MacBook. I often drive to a quiet spot and work from the car, so I wanted to use that screen as a second monitor.Nothing existed to do this, so I tried building it myself. It took over a year of failed attempts:- Hardware mod: didn't want to void the warranty - Zoom screen share: worked but terrible latency, no fullscreen - HLS streaming via OBS: ~2 second delay, unusable as a monitor - WebRTC: Tesla's browser didn't support it at the timeA few Tesla software updates later, I tried WebRTC again and it worked. But I still needed a pile of hardware: an LTE router, an OpenWrt route

Within the show hn launch space, the company focuses on its core offering rather than a broad product line.

Its current recorded stage is Show HN launch.
