Here we present what is arguably the tastiest way to design and learn about electronic circuits: make circuitry snacks!

Two of our favorite things in the world are playing with electronics and playing with food, and so it is about time that someone finally got around to combining the two. We begin by gathering up appropriate snack-food building blocks and making food-based models of electronic components. From these components, you can assemble “circuitry snacks”– edible models of functioning electronic circuits. You can make these for fun, for dessert, for your geek friends, for kids, and for teaching and learning electronics.

Urban Art at Morrow’s Nut House

Toadstools

Nut HouseWhile wandering around San Francisco, we ran across Morrow’s Nut House. There were some very silly decorated walnuts in the window, but that’s not what caught my eye. I couldn’t take my eyes off of the toadstools just outside. These capped-off pipes had been painted red with white spots. Urban art at its finest! Of course, the name of the shop is pretty good, too. Unfortunately for us, it was closed. Next time. In the meantime, you’ve got to check out the reviews people have written about this place!

How to cook hot dogs… with electricity!

[Disclaimerzilla: While we could give you lots of warnings about all the different dangers involved and how to possibly skirt them, the simple truth is that this just isn’t safe. If you are foolish enough to attempt this, you will have to deal with pointy things, raw electricity out of the wall, hot steam, and the possibility of fire. If that isn’t enough, and you succeed, you are still faced with the possibility of having to eat a hot dog. In summary: do not, under any circumstances, cook hot dogs this way.]

Humane population control for feral golf balls

Natural environment
One of our neighbors is retired and, so far as we can tell, spends approximately twelve hours per day golfing. Golfing from his front lawn, that is. While he’s an agreeable fellow and we will not begin to question the motives or reason of someone that has this compulsion, we will simply observe that our neighborhood has an infestation of foam practice golf balls.

Beyond the many hundreds of balls that are successfully reclaimed each day, some dozens accumulate in the yards, bushes and hanging potted plants of our house and the houses of our other neighbors. They get stuck in the trees and bushes, confusing us when we go to pick lemons. People remember to shut the windows of their cars when they park. Sometimes it gets so bad they clog the gutters. You can even find them in places that they could have only gotten to after three reflections, leaving you quite puzzled. But, you get the idea.

Once behind a fence, they seem to have particular trouble getting out. (Especially if there’s a dog.) Case in point: This weekend we were at one of our (non-golfing) neighbors houses for a birthday barbecue. In the back yard, down below the little bushes, approximately twenty yellow balls were visible. I didn’t look hard; these were just the ones in plain view. When I pointed them out to our hosts, I learned that they had already thrown the day’s catch (a few dozen balls) back over the fence.

What do do? We decided to practice a humane method of dealing with pests: catch, tag and release.

The whole bandMany of the partygoers got involved in the process. Most of the balls were tagged with simple designs, but some were quite elaborate. We particularly liked this set (which we didn’t make), showing four foam balls as members of Kiss. We tossed them over the fence, and they disappeared early in the morning. We’re waiting to see if any of the tagged ones reinfest the yard, or if we get new ones every day.

If our golfing neighbor is sufficiently annoyed by people writing on his little foam balls, it may even be effective as a means of population control.

 

The Flying Spaghetti Monster, on toast

four FSMs

One of the things that we kept hearing as a comment about our CNC toast story is that we really should be printing the Virgin Mary on grilled cheese sandwiches, or something like that.

As it turned out, by the time that we actually wrote about our toasting, we had already moved on to bigger and (probably) better things, like printing sugar. Since we were rushing to get ready for Maker Faire, we didn’t get a chance to make more creative toast.
But, Maker Faire has come and gone, and we’ve finally got our machine reassembled, and so here we are toasting again. Believe it or not, this is actually a step in the right direction for CandyFab as well, because these were printed at 20 DPI, already an improvement with four times as many pixels as our previous batches at 10 DPI. These four Flying Spaghetti Monster images on toast are adapted from the original artwork in pencil, by Bobby Henderson.

Oh yeah, and I put one of them on eBay. =D

Maker Faire Bay Area 2007 was fantastic!

Kill your television and make stuff!Maker Faire was a smashing success. The big message of the fair was summarized succinctly and stamped on the back of a card we were given: “Kill Your Television and Make Stuff!”

We had a great time in our little prototyping world off in the corner of the Expo hall by SRL. Near us Bathsheba Grossman had her beautiful sculptures, Fab@Home was printing with cheese and frosting, John Guy had his 3D CNC gantry next to his margarita machine, and Lee Krasnow had an entire workshop for his precision puzzle making. We were also by a couple of exhibitors (as opposed to makers): Epilog and Protopulsion, but I have to say, it seemed like the makers all got a lot more traffic than the corporate folks with their tradeshow-style setups. We were all off behind the Tesla coils, which stole our visitors’ attention hourly. Nobody could compete with the Tesla coils when they were running!

We can’t possibly list all of the cool things we saw, and we didn’t see half of the stuff there, but read on for some of the highlights for us.

Make a peepmobile

Ready to roll!

Here’s how to take your left over Marshmallow Peeps, add a few components, and make them into pimped-out peepmobiles.

Okay, so Easter has come and gone. Really gone. And if you’re like us, you didn’t eat all of your Peeps. Have they gone bad by now? Probably not. As it turns out, the yellow chick-shaped Peeps are made all year long to build up enough supply for each easter, so the ones that you get for Easter could *already* be a year old. (So why can’t you buy them all year long? You can… you just have to know where to look.)

Even if you’re still saving your Chicks to eat them later, you’re not alone. The official Peeps site has a poll up asking whether you like your Peeps “Fresh from the package or aged to perfection.” According to the results so far, a full 12% of peepeaters like to wait six months or more.

However, we seem to be digressing. Let’s just go ahead and assume that you weren’t going to eat all of them. Then whatever’s left, you can make into Peepmobiles.

A few more sugar sculptures

Sugar Soliton

This is a rendering of the sculpture Soliton by Bathsheba Grossman, as output by the CandyFab 4000; it’s a three-dimensional form made out of pure sugar. Seeing Bathsheba’s sculptures at the 2006 Maker Faire was the inspiration for us to build the machine in the first place, so it’s quite exciting to be able to print this. (The design is used by her kind permission– please buy some of her sculptures!)

This is our second try at fabbing this difficult shape. Our first attempt was at a somewhat smaller size and ran into trouble with the thin beams when *one* of our thin horizontal layers turned out to be too weakly bonded. To avoid a second failure, we enlarged the model but also ran the heater element very hot and for an extended period of time to make the pixels srong, but also larger, more rounded, and richer in color– a darker caramel.

In this view we’re looking right down at the printed layers of sugar; we think that the grain of the layers makes this look a lot like a wood carving.

Of course, that’s not all that we’ve been printing this week. Here is one more large-scale object that we made:

mobius monster

The shape is a 3/4 twist mobius strip with a square cross section and windows cut at regular intervals in all of the sides the side. Even though it’s hollow, it still weighs seven pounds and fourteen ounces– that’s a lot of sugar. We’re bringing this monster to Maker Faire this weekend, so you can see it for yourself, too.

Solid freeform fabrication: DIY, on the cheap, and made of pure sugar

CandyFab Sign

In February we gave a sneak preview of our project to construct a home-built three dimensional fabricator. Our design goals were (1) a low cost design leveraging recycled components (2) large printable volume emphasized over high resolution, and (3) ability to use low-cost printing media including granulated sugar. We are extremely pleased to be able to report that it has been a success: Our three dimensional fabricator is now fully operational and we have used it to print several large, low-resolution, objects out of pure sugar.
