COSD stake pool developed the Frankenwallet to eliminate the need for a second computer as an air gap machine for secure key storage & transaction generation / signing. We recently verified it can host a full node Daedalus wallet, in its "restricted internet" form, for those who prefer to sandbox their wallet away from regular computer operations.
Now that both implementations are being discussed with interest in the Cardano community (e.g. https://forum.cardano.org/t/stake-pool-air-gap-candidate-setup-and-security/95592/10) I believe the general community will benefit from this tool and also that more exposure will attract more feedback to verify or improve the methods & documentation.
This tool was posted in January 2021, circulated informally with a few stake pools, then organised into online book format in September 2021:
