1. roll 100 6 sided dice for entropy

2. flip a coin 256 times for entropy

3. light sensor tied to lava lamps

4. audio sensor for environmental entropy

6. camera sensor taking photo

with entropy feed to something like coldcard rolls py script to generate seed words with computed checksum

Steps:

1. Use linux entropy source daemons like egd or rngd. Every keystroke or mouse movement is like the roll of a dice. Browse Nostr for a while.

2. Take some random photos and copy the (raw if you can get it) images (or their sha512 hash) to /dev/random

3. read the required number of bytes from /dev/random
