I am the Open Heart kit developer and will run workshops to help people build the kits. I will also be giving a couple of talks about Charlieplexing.

I am a Senior Desktop Administrator by day and hardware hacker/circuit bender by night. I learn by doing things, and I don't feel like I own something till I've taken it apart and know how it works. I hope to someday support myself with my DIY projects and kits.
