Are you familiar with nostr:npub1z072s0nvldeva7a6qek3kj358f0h5gm640kkllkk52h0qrjtnw8q38wfm4? Their original product is essentially a slightly modified dot peen marking machine (often used for engraving VIN plates, etc.) controlled by a nostr:nprofile1qqs09jtvjlmyrxjn37zv70a89csegcz7rpyqjmnw29cveedhv7vagqqpz3mhxue69uhkummnw3ezummcw3ezuer9wcq3gamnwvaz7tmjv4kxz7fwv3sk6atn9e5k79kcfd7 device with custom firmware.

The code is open source and includes the ability to generate the QR code from the seed words, and keyboard masking during input based on BIP-39 words to speed things up. It also includes the ability to engrave descriptors for multi-sig wallets and some other cool stuff, definitely worth a look.

If you do end up playing with the code note that the v1.3.1 tag appears to be the last stable version for the original hardware, with most of the more recent work targeting their new SH2 device.

yes aware of seedhammer .. been following it a while.. I needed my plates to be better marked. my goal is to have the markings last the test of time even under adverse exposure conditions to the plate.

I need these to last decades for my kids and grandkids. The tools on the market did not meet my personal requirements. So im building my own. Pretty much the case for all my builds https://www.molonlabe.holdings

My use case is the same but I got the impression that most affordable laser engravers wouldn’t be able to mark as deeply as the dot peen machines.

Could you share more about the differences?

It’s a very interesting idea regardless especially with how loud the SeedHammer is.
