Sparkfun Inverter Battery Pack

13850500 Available: 1
Even though the Tron movies have been out for a while, electroluminescence is still the coolest thing since sliced bread. The only downer is carrying around a battery pack and bulky external inverter. Good news, we've found a slim battery-powered inverter for your next small EL project! This little black box takes two AA batteries and has two JST connectors for your EL wire/panel/tape. There are two modes: continuous on and flashing and it even has a belt clip!

We got a chance to play with these inverters and you can easily hack these to work with our Li-Po batteries (yep, at the fully charged 4.2V). To get inside, you'll need to remove a pair of screws (one is hiding under the CE sticker) and afterwards you'll want to wrap things up with electrical tape to avoid getting shocked (it just tingles a little).

The following current readings were taken while the pack was connected to one or more of our 3m EL wire:

Single strand always on: 190 to 260mA
Single strand blinking: 90 to 120mA
Two strands always on: ~300mA
Two strands blinking: ~150mA
Different color strands were used but the lengths were identical. Your mileage may vary. If you need to pick up some Li-Po batteries, electrical tape or EL wire to hack your own battery pack, check the related items below!

OWI Penguin Life Solar Kit

M1004876 Available: 1
Can penguins fly? You are correct! They have wings but are used as flippers for swimming underwater and leaping across the top of waves. Do penguins live in igloos? You are brilliant! But guess what? Our penguin has a special connection to an igloo. That's right, kids can build an igloo for their penguin, utilize their natural resource (the sun), and watch their waddling friend bring a smile to everyone0s face. This is a wonderful introduction to OWI's newest series: Plug-in Solar Rechargeable kits for ages 8 and up.

Kids can build an eco-friendly penguin habitat. They can see the benefits of putting solar energy to work and discover how solar cells generate electricity from light. The kit consists of a powerful solar cell, rechargeable battery (included), igloo, and penguin. It is easy to assemble: no screws, nuts, or fuss. Just simply plug-in the penguin into the igloo, solar energy converts into electric power for storage and application. On a sunny day, charging is complete in 3 minutes. Run time is fun time. Once released from the igloo, the penguin will venture and waddle for you for approximately three minutes. Because you answered the first two questions correctly, you probably know that this particular penguin does not leap across the top of waves or swim in the water.

Fun in the sun.  This is a great chance for kids to learn another green and renewable energy source. More than interesting and fun, the educational value derived could help our future generations. Love mother Earth, protect wildlife, and build a green energy life for a sustainable future with Penguin Life. It0s pretty cool!

Sparkfun Chasing EL Wire Inverter

M1043016 Available: 7
EL Inverters, if you are wanting to do anything with EL lighting you need one, period. This 3V EL Inverter is a special type that is intended to be used with a "chasing" EL wire. Unlike typical EL wires which only require a 2-pin connection, Chasing EL wire types require a 4-pin connection three for the cascading or "chasing" effect and one for common ground. Using this chasing inverter is as simple as it is to opperate its non-chasing cousin. Simply insert two AA batteries for power, plug in your Chasing EL Wire, and press the button to turn it on and select three different lighting effects (Slow Chase, Fast Chase, and Super-Duper Fast Chase).
