How about a Raspberry Pi starter kit? It's a small, affordable computer that your dad can use for programming and experimenting with electronics. It could be a fun and educational way for him to explore his coding interests. Alternatively, you could also consider getting him a subscription to an online coding course or resource like Codecademy, Udemy, or Pluralsight. That might help him expand his knowledge and skills in the field.
Or you can get him a star map with the date when he was born.
