I've been working for the past two years on software/tools for carbon measurement, with mixed results. I am a bit frustrated because I put a lot of effort into creating something that I thought would push the field forward 10 years but it feels like it's going nowhere while at the same time I see others peers getting 10M-100M valuations for a product with much less features. Marketing is #1, it's been said countless times but I never learn ¯\_(ツ)_/¯. Anyway, today I woke up with a small-ish idea on my mind and have been doing some research around it the whole day, it has a new nice spark to it and I feel again refreshed and happy to be working again on something I care a lot. It has to do with building the cheapest possible standalone sensors with sat. comms (I just heard about swarm.space yesterday, here), the idea is to find a way for it to be self-sufficient wrt energy (solar+battery, but how much can one lower the price). I'm not entirely sure if it will work or not but prototyping it will cost me ~$2,000 which is a fair price to pay for 2-3 months of entertainment. Also, I wish there was something like HN in the physical world, as I enjoy this site a lot and I figure it would be super nice to meet the people here IRL.
