Show HN: Live-Streaming Next Week's Solar Eclipse from Above the Clouds

Hacker News - Fri, 03/29/2024 - 1:29pm

Hi HN,

I've been working on a high altitude balloon along with a team of volunteers that is going to take pictures during the solar eclipse next week. The balloon has a gimballed camera (or more accurately, a gimballed mirror) that autonomously tracks the sun. Real-time video is sent down to the ground via 70cm ham radio. The comms was developed almost entirely by myself, and on previous flights we've tested it to a range of 140km. Along with the real-time video, it also uses spare bandwidth to send down high resolution imagery from several other cameras on the payload.

We'll be streaming the video to Youtube. Our channel is linked on our website. If you're not going to be in the path of the eclipse, this is a great way to participate. And even if you are in the path, this gives you a second opportunity to view it - we'll be launching from New Brunswick, Canada, which is one of the last places the eclipse will pass through.

Aside from the project website, I also wrote up a short article on one of our previous launches. It focuses primarily on the communications system since that's my contribution to the project: https://www.scd31.com/posts/real-time-balloon-video

I hope you like it, and I hope to hear your thoughts. Thanks!

Beware Scaling on AWS

Hacker News - Fri, 03/29/2024 - 12:41pm

During my first month on AWS, I used AWS Batch a lot.

AWS decided to bill me mid-month even though the cycle ends on the 31st.

The transaction failed. Instead of contacting me to resolve the issue, they completely locked me out of the account.

I've been trying to resolve this for a week now. It's Friday, and I have a demo with a Fortune 100 company next week. I have a lot of Batch jobs I need to run to get results for this demo. Not great.

I shudder to think about what would happen if this had been a launch with paid customers.
