Morse Code Business Card
Here’s a business card prototype I made today that has an LED and a piezoelectric transducer. It has a Morse Code table as well so you can send signals with it. 🙂
I’ve made other cool business cards.
Here’s my laser cutter doing a different card a while back:
One idea I had (but I’ve not got an elegant solution for) is to mount only half of the PT. Then people could twang on it like a juice harp.
The current system the Piezo is suspended at two sides from the cardboard so if you press it against the table like a button it is flexing…
Hi Doug,
I found that the ones with lower voltages were the amber (the ones I used). Red and green are supposed to be lower voltage too but the ones I had didn’t give much of a flash.
When it’s dark it’s not too bad. I had them at the pub last night and they were okay.
Notice I managed to go with single layer so the fab step is pretty easy. In fact the card holds everything in place when soldering since I put the legs of the LED through the cardboard congregations.
That is really cool. Now I’m wondering if different LEDs with different mcd values might give even brighter flashes.
This is definitely on my Christmas wish list.
Doug
