Congrats on being smart!
While I'm not technically unemployed I am rather underemployed and my contract work can sometimes disappear for months at a time.
In terms of skills that I've learned, I've been teaching myself piano with
Synthesia. And about 8 months ago decided to pursue a career as an actuary, 2 exams passed, third coming up in April. No specific job leads yet, but I'm hopeful things will pan out shortly.
I've also been doing a lot of reselling of items from Goodwill, Target and Meijer. Started off at Goodwill checking books to see how much they were worth, did alright considering how little effort it took (would find $20-$30 books every now and then. Found one that I sold for $545, but that's a once in a lifetime find). Then I followed Slickdeals a bit more and was able to find some super sweet clearance deals from Target (since Target clearance is highly variable from store to store it helps that I have 4 targets within easy driving distance). Then I discovered Meijer (which is a region chain, basically like a Super Walmart except slightly classier), which has the most nonsensical and awesome clearancing ever.
Just bring your smart phone and check the prices on Amazon to see what they are selling for.
I only seriously did the reselling stuff for the last 4 or 5 months of 2011, and Amazon sent me nearly $10,000, about half of which was profit. Pretty easy money for very little work and very little risk. Oh, and reselling you'll love black friday, I was averaging like 8 orders a day for a week. It felt great
And you mention you needed an OTA antenna. Try building on yourself out of coat hangers. I'm dead serious about that too. I live in the far NW Chicago suburbs, and you can barely get OTA transmissions. With a standard pair of bunny ears I would seriously get maybe one station if I was lucky. Many people in the neighborhood had those massive antennas on their roof.
Anyway, I decided to try out this

And lo and behold I picked up every station with the exception of CBS. Cost nothing out of pocket (as I had everything lying around. But if you had to buy everything it would cost less than $10) and it works from inside the house too. So check that out first, you might not need anything better.
And slickdeals is awesome, so much money to be saved if you can wait around for a deal.
