Ask HN: Who wants freshly roasted coffee?

1 pointslamroger11mo ago2 comments

Hey y'all - I consider myself a tinkerer and in the vein of doing things that don't scale, I want to send you coffee that I roast.

I have a couple bags of green beans to choose from.

If you want to print a picture or your art on a label, send me an image!

If you prefer a roast level, let me know too.

* Colombia, Finca La Riviera Sudan Rume * Colombia, Finca La Rivera Gesha * Colombia, Finca Milan Anaerobic Passionfruit Co-ferment * Vietnam, Lostus SHG * China, Yirong * Mystery Blend

It's free (or send a donation to charity). Send me an email - me@<username>.com or msg me on LinkedIn - https://www.linkedin.com/in/lam-roger/

Here's a video of me roasting on my patio applying some object detection to the beans to get the average color - https://www.linkedin.com/feed/update/urn:li:activity:7123095011449085952/?originTrackingId=Eqpm7A0vQ1Cu2G1j7msaYg%3D%3D

Do you have a technical write up? Is the object detection method explained in the repository? I think a slightly more technical artice would get more traction here. But don't forget to include the video!

Hey! Appreciate the links and sorry for the late reply. Thought this just got grabbed by the spam filter when I wasn't seeing it.

I have a small writeup here: https://lamroger.com/blog/2024-03-10-coffee-roasting-tech/ and the video here: https://www.youtube.com/watch?v=shMMuNuH3cE

But short answer is I finetuned a model with the help of Roboflow, grabbed the pixel values in the bounding box and avg'ed the values.
