Pumpkin Spice Truffles

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?”

Easy Itty-Bitty Blinky LED Jack-O’-Lantern

By on

Halloween is tomorrow! Do you want to bring a carved pumpkin to work, but aren’t allowed to burn candles in your cubicle? Do you want to carve a mini-pumpkin that’s simply too small for a candle?

Or are you just running late and need to make a procrastinator’s pumpkin?

If you said yes to any of these questions, we just might have the solution that you’re looking for. Here’s an easy way to make a tiny blinking-LED jack-o’-lantern.

The blinking LED circuit is borrowed from a Tirefly, a commonly available type of motion-sensitive light that attaches to the valve stem on the wheel of a bike or car. Our quick modification (less than five minutes and no soldering) defeats the motion sensor so that the LED can blink all day (or all night) for you. (For hardened geeks who want to solder something anyway, we’ll also show you how to mod the circuit to use a higher-capacity battery.)

[Update: (10/2008) A reader wrote in that they have had trouble getting the circuit to blink continuously; the tirefly circuit may have been changed. (Confirmed– It has changed!) Do any other readers have recent success or failure to report?]

Building a Robotic Dalek Pumpkin

EXTERMINATE!!! EXTERMINATE!!! EXTERMINATE!!!

We Evil Mad Scientists like Halloween. A lot.

You might have already seen our old-school Cylon Jack-o-lantern. Here is another halloween electronics project, hopefully in time for you to make your own: It’s a radio-controlled robotic Dalek that can move around and turn its head. Oh, and did I mention that it’s a pumpkin?

Make A Cylon Jack-O-Lantern

By on

It’s a pumpkin! It’s a Jack-o-lantern! It’s an electronics project! It’s… a Cylon!

Cylons are great. They’re evil, menacing, and shiny. They have glowing red lights, computer-monotone voices, and they aim as precisely as imperial stormtroopers.

For halloween this year, we made Cylon Jack-o-lanterns in both large and small versions.

The design consists of two parts, a pumpkin-carving part and an electronics part. The big idea, of course, is to make the Cylon’s red eye scan back and forth.

How well does it work? Take a look! (Youtube)

This week’s Weekend Projects Podcast at Make Magazine is about making a programmable LED pumkin.

Our Cylon is made with a very different approach. It runs on a 9V battery and uses two cheap integrated circuits (a 555 and 4017) that together control six LEDs (or six groups of LEDs).

Circuits like this are quick, easy, and cheap to build. It’s also fun merely from the standpoint of making something that people might expect to require a microcontroller. For this particular circuit, it turns out to be cheaper and faster to do it without one.

If you’re handy with a soldering iron, you can build this circuit for less than ten dollars, in less than two hours, without any programming at all.

How to Build a Better Bat Costume

By on

Halloween is coming right up, so it is time to post one of our favorite costumes to help get everyone in the spirit. This is a darned good looking bat costume you can make from a hoodie and an umbrella.

Yes, similar costumes have been made before. Even Martha‘s done it. However, our version is better.
