first impressions matter. taiwan bitcoin hub just opened and the design is excellent. the typography, posters, slides all looked good. taiwan has some cracked designers with a good taste, lucky to have met a few.
i vibecoded a cypherpunk quote bot using shakespeare during the building with open source ai workshop at @btcplusplus taipei. i've been feeding my llm rare interviews from chaum, may, diffie, and zimmerman etc...and asking it to extract relevant quotes and add them to the database. i found some gems, some quotes i suspect many people haven't heard. follow cypherpunk quotes on nostr if this sounds like something up your alley.
the physical feel of technology makes such a difference. bitkey vs coldcard is night and day. you can immediately tell how much they cared about the craft of the object and how people would hold it and use it. image
my first hardware project: an offline cashu wallet on an esp32. generate ecash, send it to the esp32 via bluetooth, esp32 decodes the ecash into individual proofs, pick any proof and display it as a QR code for redemption. the esp32 never touches the internet. completely airgapped. just receives tokens, holds them, and displays cashu tokens.
