Wow, this is so cool! I found this from @dkbit98's other great thread: AirGapped Hardware Wallets. Good job, @jreesun, I think I will actually build one 
Wanted to build a SeedSigner, but honestly there are more components that need to be sourced and more assembly, so I love that you use an M5Stack as base for this project. I'm a big fan of these devices, even though I haven't gotten around to buying one to play around with yet, so this looks like the perfect opportunity.. 
One big advantage is also that it's not so expensive. The other airgapped hardware wallets are much more expensive or not open source, etc., while here you actually buy a device without any firmware at all, which I love and it's around 50 bucks.
As for:
I'd still not store too much on such an M5Stack, but would be quite fun to play around with one for sure..

Why would I go with a product with some code with this warning:
For me, the difference is that this is air gapped and open source. Trezor is also open source, but not air gapped. I have yet to look more into this specific M5Stack, since I'm not sure if it has a secure element or not, but if it had, that would be another advantage over the Trezor. Of course, Ledger is not an option for me, but there are other topics about Ledger. And finally, they're both more than 50 bucks, even when on discount.Quote
WARNING: While functional, this is currently alpha-quality software and could have bugs or other issues that might cause you to lose your coins. Use at your own risk!
...when for about the same price I could buy a Trezor or Ledger?I'd still not store too much on such an M5Stack, but would be quite fun to play around with one for sure..
