This is the famous Blue Box made by @stevewoz.bsky.social and sold by partner-in-mischief, Steve Jobs.

I did a few designs with the famous Cap'n Crunch bo'sun whistle used back in the day for phone #phreaking.

#Maker and #hacker lore we can proudly wear.

Here's the first one. I'll make the other ones available over the next few days.
