A Traveling Exhibition of Modern Art (the Halloween Costume)

By on

In the daylight

For halloween this year, we put together a “group” costume: a traveling exhibition of modern art. Each person wears a painting in the style of a modern artist.
One of the cool things about this costume is that it is a fully extensible and scalable design: it will look better the more artists that are represented. Having a real crowd would let you include some less well known artists, while still being recognized as a modern art exhibition.

Make a Robotic Snap-O-Lantern!

The Snap-O-Lantern is a robotic mini-pumpkin. Normally, it just sits there, in disguise as a boring old pumpkin. But, every twenty seconds he comes to life. His LED eyes turn on, his jaw slowly opens, and then SNAPS shut– and he goes back into stealth mode.

What’s inside? A small hobby servo motor, driven by an AVR microcontroller. This is a minimal microcontroller project, and is very straightforward if you happen to already have a setup for programming one. We’ll walk through the carving, setup, programming, and electronics. This is an open-source project, one of the world’s first “gpl-o-lanterns”; source code is provided.

Easy halloween project: 8-bit gourds!

By on

Gourds

A quick, low-tech halloween project: we hollowed out a couple of miniature decorative gourds. You can get these by the bagful at the grocery store, next to the mini-pumpkins. The one on the left had a kind of wrinkly base that adapted itself well to this shape, and the one on the right had more of a conical tip that we cut off to make a flat base.

Gourds like these have a hard shell, about 3 mm thick, that is rather hard to cut through. We used a loose drill bit (turned by hand) to make the initial cut. From there, a regular hobby knife (e.g., x-acto) works well. Once the soft flesh and seeds are scooped out, the hard shell can dry to make a semi-permanent display.

It’s unreasonably fun to walk around with one of these in each hand, reenacting the age-old chase drama. Especially when the little yellow dude chomps a big white dot. Now who’s chasing who?!?!

You can find more pumpkin projects in our Halloween Project Archive.

Halloween projects and Texas

By on

This week the lab staff is heading off to Austin, Texas, our former stomping grounds and site of the other Maker Faire this year!

As we noted earlier, we’ll be doing a demonstration of how to build an excellent Bat Costume out of an umbrella and a hoodie. However, our primary project there will be our booth: High-Tech Pumpkins, where we will show up to a dozen (fingers crossed) halloween-themed projects, TSA willing. (Thank FSM it’s Austin, not Boston.)

While we get everything together this week, our publishing schedule will be a little wonky. However, halloween is just around the corner, so it’s time to dust off a few projects from our halloween archives!

Pumpkin Spice Truffles

By on

Truffles

The fall holidays are fantastic ones: Halloween is all about costumes and candy and Thanksgiving is all about food. Here is how to make one of our favorite fall treats: pumpkin spice truffles. (Yum.)

To get the note-perfect flavor of traditional American pumpkin pie, we use the spice ratio from the old-standard can of Libby’s pumpkin (here is the recipe from under the label). Bittersweet chocolate has a stronger flavor than that of pumpkin, so we actually use twice the spice of a pie for a small batch (well, small for us batch) of truffles. The amazing thing is that these pumpkin-free wonders taste uncannily like pumpkin pie. Not that anyone will have trouble distinguishing your truffles and a pie, but you just might get asked, “Are these actually made with pumpkin?”

Time to Make a Cylon?

By on

Make: HalloweenStarburst

Yay! We finally got our copy of the Make: Halloween Edition.

This special issue is actually available in two different covers, but we particularly like thisversion because of that little starburst: “Make an LED Jack-O’-Lantern!”

On page 60, you can find the article that we wrote about how to build the Larson Scanner (named after Glen A. Larson); a scanning eye for your old-school Cylon or KITT pumpkin projects.

Red Eye

The article is actually a slightly updated version of our project from last Halloween, Make A Cylon Jack-O-Lantern. Last year’s how-to is still online— and we have recently checked to make sure that all the parts on the parts list are still available.

Either way, let’s see those Cylons! If you build one, please post your pictures in the Evil Mad Science Auxiliary.

Just in time for halloween: Bats

By on

bats hanging like fruit

The animals that everyone hears about from Australia are things like koalas, wallabies and platypuses. But the real stars, as far as I’m concerned, are the bats. We saw a few bats in the zoos we went to, including ghost bats and flying foxes. But just walking along in the afternoon in the botanical gardens in Sydney, we looked up and happened to notice that what was hanging from the trees wasn’t leaves or fruit – it was bats. Hundreds of flying foxes. They chattered at each other and flew from one roost to another. While the echidnas were awfully cute bumbling along at the zoo, and the cockatoos were fun to watch at the park, it was the bats in the garden that stole the show.

The Perfect Ammunition for Valentine’s Day

By on

Valentine's day ammo 2

The holiday that we all collectively love to hate is sneaking up on us, which brings us right back to that all-important question: Exactly what type of projectiles should we be shooting at people? (Isn’t that what you think of when someone mentions Valentine’s day?) And yes, we’ve found the answer: Customized conversation heart ammunition.

Don’t have a decent catapult for the job? This is your perfect excuse to build one. You can make a Lego trebuchet (a leguchet), like we did, or take a peek at all the hot trebuchet action on Make this week and get creative.
