      well icebreaker board could be used as a badge :) most conference badges do not have a name on them. Ice breaker with 4 LEDs and 3 buttons can be programmed with simple demo code.

      There is the option to have an additional PMOD board connected to the iceBreaker with additional IO (like 8*8 matrix display, button, microphone, ..) and fixated with plastic straps.pic.twitter.com/HF1YgpAico

      Right. And 8x8 is enough for even dispalying names scrolling. Additional board can be even hand soldered and produced faster if needed.

      The question is: How would you provide the power supply as a nice and cheap and wearable solution :-( @fpga_dave

      Probably a small LiPo, 100-200mAh should be fine if well designed. Might want switching reg for 1.2V at least though.

      I would look into using the AA aka. 14500 format LiPo cells. The holders are easy to get, rechargable, include battery protection circuitry and are more sturdy in a conference environment than the flat pack batteries. I would include battery charging on board too...

      That's a good idea, I would agree with that - unless we wanted to go crazy low power and use something like LIR2450 or even LIR2032.

      I made some paper samples of a badge to test handling and button press position, and I like this layout the most (one or two AAA).pic.twitter.com/Rp6VRJwFXU

      Maybe as different board with the LED part as break-off section. (Small battery and step-up circuit on the back.)pic.twitter.com/g3UOT0Sm4a

      Looks awesome, still wondering whether a tiny OLED or LCD would be better or not though

          My idea was to use the iceBraker as it is (which is manufactured in larger number), and let the people solder the IO PMOD so that they can have a Badge. This would reduce the cost of the PMOD massively (not like 3*BOM costs). LCD connectors can not be soldered by people.

          I know a bunch of #badgelife people. Letting the attendees solder anything is a very bad idea! It ends up in a huge support effort during the event. :(
