Maker Faire Day 2 - Moonisphere is Too Big to Fail

Recycled Cardboard Moonisphere Under Construction

After a sweltering day building the Moonisphere on day one, so far we have merely a Moonicircle, but fear not! We were able to do a lot of prep work in the shade, cutting massive amounts of cardboard into appropriately sized strips to lay down.

Once the framework is made, we'll cut slots with a jigsaw, and fit it all together like an old-fashioned barn raising.

The crew from the New York Hall of Science has been great at redirecting all of their waste cardboard to our pile, and there will be plenty of cardboard from wolphram-alpha swag integrated into the Moonisphere.

If you find yourself passing by our tent, give a hand in constructing a wicked cool piece of temporary art! We're right by the 3d printers at Maker Faire, all day today.

Evaporative Cooler Update!

Methinks the evaporative cooling set-up did it's job just fine! Between 11:00 to 1:20 the inside temperature creeped from 85 F to 90 F and has held steady since then (writing this at 3:30). I'm calling this a not-too-shabby success, since the outdoor temperature climbed from 91 to 97 in the same amount of time.
Evaporative Cooler Triumph!
So I didn't quite reach the wet-bulb temperature of 84, but here I am writing this entry - a bit balmy, but if it were 97 indoors I'd probably have passed out before finishing this paragraph :)


Lots of thanks to Make: Magazine for featuring this project!

Scrapwood Trellis



It's June and the plants are going vertical for sure now. Our snow peas needed some help with their ascent so I put together this trellis from scraps I have lying around. Kept my Triangle Square (def my fav new tool) out on the ground while framing it up. The design looks haphazard but keeping everything at right and 45 degree angles makes it coalesce I think.

Wood Gasification Stove Saves the Day!

The blizzard that hit the northeast states recently left many without power, running water, or heat. I was one of the many who found myself in this predicament, envying those neighbors of mine with generators. Luckily, my homemade wood gasification stove, fashioned from tin cans, saw me through the worst parts. One of these is super easy to make, and I was inspired by this simple instructional video:



When my wife and I awoke the first morning after the storm hit and were still without electricity, I loaded the stove up with scrapwood, grabbed the grill from our toaster oven, and brewed some espresso in the Moka Pot.

Then Melody started work on breakfast - scrambled eggs and toast! We cooked it up on the living room floor, just making sure to keep the stove on top of a few ceramic plates for heat dissipation. Be sure you're adequately ventilated when using one of these stoves- these gasses are not so safe to breathe in large quantities.

After nightfall the house would get really chilly so we curled up and played some scrabble or listened to the radio, generating heat with the stove one batch at a time. By breaking up the combustion process into discrete parts, this stove generates an even, virtually smokeless heat. All that's left at the end is a small pile of ash. All you need is a squirt of lighter fluid or rubbing alcohol to get it started. If you have trees nearby you'll be with heat for a long time. This thing can run on twigs!

The next plan is to build an even bigger one with a longer burn time. It was a drag to have to reload the little guy- introducing fresh wood to a live batch seems to disturb the gasification process and generates smoke. A coffee can sized stove would burn for quite a while.
