Stylophone business card project from

Printed Circuit Boards as a business card are a great gimmick. I’d seen ones with USB ports etched into them, which enumerate as a keyboard and then type a person’s name or load up their website. It’s just about possible to build them cheap enough to hand out as a business card, at least if you’re picky about who you give them to.
A couple of years ago I took a stab at making one for myself, but I didn’t want it to be pointless. I wanted it to do something useful! Or at least entertain someone for longer than a few seconds. I can’t remember quite how I got the idea of making a MIDI-stylophone, but the idea was perfect.

    At this point I have serious reservations concerning the opinions those receiving “clever” PCB business cards form about those handing them out – sort of along the lines of my earlier note about wearing a DIY watch.

    If a business card can’t handle bending [in my wallet] it’s a fail. All the “clever” functions are secondary.

      This is probably stocked in his music or work studio, or in a hard case. Never has to go in a wallet.

      • Alan says:

        Once he hands the business card to someone, he loses control of how its stored.

        So is common sense so rare a commodity these days that something like this is an issue? I mean, sure I understand Max’s position and he can be jokey. Okay good, since this seems to be an issue, why are all those teenagers using super-dangerous things like Ford, GM, Honda…? Come on, assume folks have some common sense and some sense of personal responsibility. We can’t be responsible for every snowflake. If they put in in their pocket, fall over, and guillotine their dick, then it’s entirely their own fault, heh.
