Every other Saturday would be fine with me. If possible I'd like to keep them mid to late morning so that I won't conflict with any family plans this summer.
I have a few extra soldering irons and I buy solder in bulk so I'd be willing to help with a soldering clinic. How about $15 for materials and you will walk away with a (hopefully) working RBBB or BBB (Arduinoo clones) from Modern Device. This would cover the cost of the boards and shipping. *If the parts cost less due to qty the class will be less.
Any interest let me know and we can set a date and coordinate an order.
