My Trip to Maker Faire



Getting ready for the earth oven workshop this weekend meant that I never got around to reporting on my trip to Maker Faire up in San Mateo on the 19th. I spoke in the low-tech "Homegrown" shed far away from the high powered tesla coil displays happening elsewhere. To add to the low tech/high tech irony, I was not able to use my PowerPoint and had to speak extemporaneously. This worked out for the better, as I was able to pull up a member of the audience to demonstrate her solar cooker--much more fun than showing pictures of solar cookers. And, after all, maybe it's time we retire PowerPoint.

Some of the things I spotted at Maker Faire:


Long lines for the tiny house. I'll review Lloyd Kahn's awesome tiny house book later this week (he gave a talk just before me). Not sure what's up with the white robe outfit in the foreground.


Also spotted: bamboo bikes!


Cornelia Hoskin, who curated the Homegrown Village part of Maker Faire, her husband and new bambino. Cornelia also runs homegrown.org.


Yes, there were paintings done by snails.


Solar popped popcorn.


A rep from Sweet Maria's Coffee gave a great demo on all the ways you can roast your own coffee.


Expensive AK-47 toting garden gnomes.


And solar powered bikes. Not sure how this would work out on an LA street.


Someone in the Homegrown area was processing greywater in bulk containers planted with bamboo.

Overall I had a great time. It was a wee bit heavy on the robots and 3d printer gadgets but that's to be expected. At least there were a few chickens present to balance out the proceedings. However, next year I'm coming with an overhead projector:

Solar Garden Helper Thingy


From the always cool Build It Solar blog, a "garden helper machine" built by Randy, aka "PD-Riverman".
I really Love gardening but I have a bad back and when it comes to staying bent over in the garden it gets rough. So I built this Helper Machine. I  call it My P-Machine. Planting/Picking/Pulling weeds/Putting around the garden machine. 
It's powered by two 12 volt 80 watt solar panels that charge some golf cart batteries.

I feel like adding learning welding to my New Years resolution list!

So-So Tomatoes Become Excellent When Dried


As we reported earlier, we weren't thrilled with our cherry tomato choice this summer. They were just plain dull. They were also rather large for a cherry, more like mini-plum tomatoes, which made them awkward for salads. But they were healthy plants, and very, very prolific. In situations like this it is good to remember that tomatoes which don't taste good off the bush often cook or dry well. The ratio of skin and seeds to pulp in these tomatoes made them a bad candidate for sauce, so we've been drying them.

And man, are they good dried. Like tomato candy. It's very hard not to snack on them, but I'm trying to save them for the depths of winter, when I really miss tomatoes.

We have maybe a couple of quarts of them now. Several years ago we had an absolute disaster involving a pantry moth, its many offspring, and one big jar of dried tomatoes. For this reason I'm storing the dried tomatoes in a series of small jars, to offset the risk. Another good tip for fending off moths is to freeze any food stuff which you suspect might be at risk for 4 days to kill moths and their larvae.

How did we dry our tomatoes, you ask? Usually we use our homemade solar dehydrator, but this year we've got a friend's electric dehydrator on loan. It seemed wicked to run the thing day and night, but it dries a lot faster, and with less work overall, than our solar set-up. (Oh, the wonders of Modern Living!) The one thing I did not like, though, was the constant noise. The dehydrator sounds a little like a running microwave, not loud, but persistent. I was always half-consciously expecting to hear the microwave "ding!" at any moment.

So, while the electric dehydrator let us process this crop of tomatoes in record time, I don't think we're going to ever buy one ourselves. Old Betsy, the wonky wooden dehydrator, suits us well enough.
