Zivko the Robot. Just call her (or him--it’s unclear and we don’t like to ask) “Zivko” because “the Robot” is her last name. Using just a screwdriver and side cutters, you build Zivko from this 107-piece S.T.E.M. kit. Set the mode for “Follow Me” or “Explore,” and Zivko will, yes, track you, or evade obstacles, respectively, via an infrared sensor and micro-controller programming. Interactive LEDs and sounds abound. Measures approx 5" x 5-1/2" x 6-1/2" when assembled with all (6) legs. You add (4) “AA”s for power, which is the least you can do for someone this cute. Ages 10+.

For tyro electronics wizards: build your own dual white-LED strobe light. You'll need a 9V battery, solder and a soldering iron. Features a speed switch and rate control knob, and will oscillate between once and a seizure-inducing 60X per second. Draws 40mA. Ages 10+, as some soldering is required.

An advanced kit compared to the others, a little more deluxe and a little more complicated. It is an AM/FM radio kit from Elenco with over 80 pieces divided into lesson groups. PC board shows component placement to help learning and to minimize errors. It has (14) transistors and (4) diodes and the case measures 11"x 5"x2-1/4". Ages 12+, as considerable soldering is required.

Electronics fans, musicians and budding Sci-Fi sound engineers will love this little starter electronics kit for making a mini version of a theremin, the venerable capacitance-based instrument that’s synonymous with eerie sounds. This one skips the volume antenna, but has a quantization mode as well as a continuous swoop via the pitch antenna. You add a 9V battery and some minimal soldering skills. Includes all parts, including IC sockets. Measures 2” square, and includes excellent instructions. You might want to get a little project box for it. Made in the USA for Madlab/Velleman.Ages 10+.

Cool kit to introduce the beginner (age 10+) to the fabulous world of electronics. You will learn the basics of putting together circuits through over 50 projects building actual devices like an alarm, a radio, a metal detector and much more. The simple but complete instructions explain voltage, current resistance etc. This kit from Elenco is a giant "breadboard" with wires that can be connected to form the circuits as explained in the instructions…and all without soldering! A fabulous educational item at a fabulous surplus price!! For ages 10+.

The vegetable- or fruit-powered clock never gets old. You get (2) copper and (2) zinc electrodes, 4" x 1/8", a couple of pieces of wire and a little 1-1/8" dia LCD clock. You don't add any batteries, just bring a lemon, lime, grapefruit, potato, kiwi, strawberries (or some cola if you're not a healthy eater) and time is on your side. Ages 5+.

Bells, whistles, sirens, rain and metal detectors, amps, timers!

Just what can solar power…power? Find out with RobotiKits 6 In 1 Educational Solar Kit that comes with one solar module and one gear box, and 21 snap-together plastic parts. No tools required. Build 6 different solar-powered models (windmill, revolving plane, airboat, plane, car, solar puppy) or one of your own. Assembled units are roughly 4" across, in varying heights. For age 10 and up.

Electronic fun with just a hint of soldering from Madlab. You pick: the lie detector kit, with a PC board and components, or the LED logic game with diodes and transistors that pit your skill against moving a peg along (36) pads. You should be able to assemble either kit in under an hour with a little light soldering. You add a 9V battery to both. For ages 10 and up. Soldering iron not included. But we have one, and it’s item #88242 for $6.95.
