Is the telescope design available anywhere for hobbyists to build? I can't seem to find anything in the article or in a separate search. I'd be interested in perhaps putting one of these together to do radio astronomy with my kids.

Search on “diy radio telescope”, that gave me lots of projects and videos

Can we have more stories like this on the front page please!
Pay08•32m ago
The vast majority of these kinds of stories are complete bunk.
ssgodderidge•21m ago
Why? What do you mean by “bunk?” Do you have any examples you can point to?
bix6•15m ago
Regardless of its bunk coefficient this is still exciting and inspiring, especially for students or low resourced people.

What an awesome story. Not too many stories about Aussies out there, but what Han brothers are doing with Unsloth in AI, and stories like this one, makes this fellow Aussie super proud!

I would have been all over this if we had one of these when I was in school. Very cool project.
ssgodderidge•19m ago
Honestly at $500 I still want one. I’d love to see the design open sourced!

It's a shame the title was so interesting, but not enough for a person to spend time write something about it in the body. Not just as a compare and contrast, but as a meaningful conveyance of the story and details. That's where a real article comes in - to be more than just an expansion of the original prompt.

Does anyone know if there is an official site/repo/page for this project somewhere?

Very interesting project, I'd be interested in seeing their system architecture in more depth and what tricks they used to bring the unit cost down.

Another radio telescope project I saw a while ago """misused""" low cost universal GNSS receivers ICs (MAX2769) as their RF frontend, which I found to be novel since these chips operate in a weird performance regime of low resolution (1- or 2-bit output) but very high sensitivity.
