Ring Blinking

On the 8th and 9th of July 2014, there will be an annual wearable-technology conference held in San Francisco. I believe this is the 12th conference Wearable Technologies has organized. This year I have been asked to speak at the conference about my Peltier Ring! You can see the details about the conference here:

I am very excited to see all of the new technologies that will be shown at this event. Also excited to go back to San Fran. If anyone – makers, hackers, fans – want to see the ring and are not able to attend the conference, please let me know, I will be exploring the city all week and networking as much as possible! I would love to check out some hackerspaces as well. If anyone knows the hot spots, let me know!

Oddly enough I have a few ring sizing tools hanging around (thanks to my Grandpa having lots of random tools) so I measured the two fingers it would go on and away I went with a design.
