General workshop collateral

Hi all!

I feel like I'm getting enough Arduino competence to investigate starting a simple workshop in the Austin, TX, USA area. In the grand open source tradition, I thought I'd first ping this forum to see if anyone has some collateral/syllabi that I can reuse before I start trying to generate my own.

I'd also welcome suggestions and tips on what makes a successful workshop from those who have attended/conducted them in the past.
