Not shown: Solar Charger Shield (from Seeed Studio) and RS-232 Electronic Brick module. The former arrived on 1/21 and who knows when the latter will arrive. Already hacked up one of the chargers to get the Solar Shield running off the solar panel and Li-Ion battery; it works spectacularly well.
Some of this came from Sparkfun Free Day, some was paid by Palm's generous early-developer gift certificate at Christmas, and the rest came very cheaply because I'm a frugal bastard.
Ingredients:
4-digit 7-segment LED
12-key Keypad
8-bit Shift Register 74AC164
Some ohm
Piezo Speaker

A potentiometer controls a servo motor so you can set a display to show what mood you're in. I had to modify the pot to stick in the breadboard better.
Commissioned piece made of cardboard, hot glue, wood glue, paint, and vellum with Arduino inside the box structure.
The LEDs (one red, one yellow) flicker in a random pattern and look like a flame burning inside. Complete with on/off switch!

Our Maker Art class created a Haunted House in fall 2016. In this after-school workshop at the Lycée Français, students ages 7 to 10 built a fantasy world together, with magical creatures, ghosts, witches and other spooky characters.
We combined arts and technology to bring their creations to life: each student created their own room in our haunted house, and animated their characters with motors and simple mechanisms, adding lights and sounds to tell their stories.
Students started by designing their rooms and characters, and built them in their own cardboard ‘wonderboxes.’ We then asked them to sketch up their individual visions of the Haunted House and combined them together. Children worked in teams to build some of the more complex features: a clock tower, an elevator and an animated graveyard zombie, all powered with Arduino boards.
I’m very grateful to my associate teachers for this class: Sarah Brewer and Edward Janne were amazing partners and empowered our students to create their own interactive art, helping them bring their ideas to life in a playful way that made learning more fun.
We taught this class weekly at the Lycée Français in Sausalito, with 8 school students in grades 3, 4 and 5. We met every Thursday at 3:30pm, from September 15 to December 8, 2016. Many of the materials we used in this class were prepared at Tam Makers, our makerspace in Mill Valley.

Example in how to drive a unipolar stepper from the Arduino board using a ULN2003A darlington pair chip
A low cost Arduino clone, Read my review here.
Here is what the completed kit looks like and here it is with an ATmega 328 fitted.
The Arduino Uno is a microcontroller board based on the ATmega328
It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.

I didn't go to school today, but all my lab crap is at home, anyway, because I always seem to be doing my homework after midnight (which is when the shop closes).
