This is for my New England readers.
I am a member of a hackerspace in Connecticut. You know the one.
I'm willing to do short free classes on various topics I'm semi-qualified to talk about. Like building simple antennas or basic RF test equipment.
The only cost would be a donation (as you see fit) to the space. A few bucks would do.
Unlike my out of state classes, which cost me some $$$ to set up, the overhead of doing a short class at the space is almost non-existent, and helping support them would be a good thing.
Let me know.
