Anything else the community should know?

Hong Kong-based solo mining hardware retailer. Vendor confirmation and community links were already stated in the original PR text. This update only aligns the body to the current PR metadata validator.

Thanks @calvincryptohk — formal update from my side.

vendors/calvin-rig-technology.json was empty (1 byte). I restored the vendor-authored JSON from the original commit message into that file so schema/slug validation can run. Logo filename/size already looked aligned. I also aligned the PR body to the current metadata form.

No qualitative vendor-review changes were made.
Leaving final qualitative/manual review to @skot.

[calvincryptohk]

Thank you @DerekLoadout for the fix!

Just to confirm for @skot's review:

• calvinrig.com is our live store with DDP worldwide shipping
• Every unit goes through a 2–4 hour burn-in test before dispatch
• We carry genuine Bitaxe Gamma and NerdAxe open-source hardware
• Happy to answer any questions

[calvincryptohk]

Hi @DerekLoadout — thanks again for the CI fix. Checks are
green and there are no conflicts, so I believe this is ready
from my side.

Is there anything else I should add for the qualitative
review, or is it simply waiting on @skot's queue?

For context: calvinrig.com now has 32 verified customer
reviews, and our Bitaxe product pages link back to
bitaxe.org as required. Happy to provide anything further.

No rush — thanks for maintaining this list.

Sorry, Jingle miners are a closed source bitaxe fork and make this listing not eligible for the legitlist.

Hi @shot — thanks for flagging this, and appreciate you keeping the list accurate.

You're right — our catalog did include a Jingle Miner Hashcard (12.5T) listing. I've now unpublished it from both calvinrig.com and our local HK storefront, so it's no longer part of what we sell.

To reconfirm for @skot's review:

• Our remaining lineup is exclusively genuine, open-source hardware — Bitaxe Gamma series, NerdOCTaxe, and NerdQaxe++
• All Bitaxe product pages already link back to bitaxe.org, as noted earlier in this thread

Happy to share a screenshot of the removed listing if that helps close this out. Thanks again for the review.

[skot]

Great, thank you.
can you help me find the link to bitaxe.org on https://calvinrig.com/en-us/products/bitaxe-gt-801-1-5-th-s-35w-the-ultimate-beginner-solo-miner ? Maybe I'm missing it

[DerekLoadout]

Thanks @calvincryptohk — formal checks still look good on my side. Vendor JSON, slug, logo and PR metadata all pass validation, and CI is green.

Leaving final qualitative/manual review to @skot, including his follow-up above.
