Copper and Zinc Plate Battery Experiment Kit (DIY fruit battery)
Description

Do you know that fruits can produce electricity? When two different metals are placed in a common conducting solution which in this case, the juice inside the fruits, electricity will be produced. This is the basis of the electrochemical cell or wet cell. If you have a piece of fruit, a couple of copper and zinc plates, and some wire, then you can generate enough electricity to turn on an LED! Making a fruit battery is fun, safe, and easy.

Watch a video on this kit at https://youtu.be/gmtJWYzdPbk

Get this kit to keep your kids occupied with hands-on activities while enjoying the new knowledge while having fun! This DIY kit is simple enough to be built by 4 years old children, with parent's help. And children 6 years old and above can build it by themself! Let them explore electricity at a young age! You can also let your kids understand how an electrochemical cell or wet cell works. Awesome!

Note: The fruits used in this project SHOULD NOT be eaten. Care should be taken when handling the metal electrodes, LED and alligator clips.

The experiment can be conducted with various types of fruits:

Switched Battery Box 4xAA (6V) (switch batt box 4xAA)

Description:

This battery box is designed for use as a nice switchable, portable power pack, and fits any four alkaline or rechargeable AA batteries in series. The body is moulded in black ABS Resin and has a slide on detachable lid which can be locked for extra security through use of a small provided screw. It even includes a very useful miniature on-off slide switch which is very handy for wiring to projects that don't have a switch! Connection is via two flexible stranded red (positive) & black (negative) 26AWG wire leads, which are approximately 150mm in length.

The four batteries are held in series, for a nominal output of 6V DC (6.4V when fresh, 4V when dead), and 4.8V DC for rechargeables (5.2V when fully charged, 4.4V when discharged). Using rechargeables will make this work nicely with nearly any 5V project, with alkalines you may want to put a 1N4001 in series to drop the voltage from 6V down to 5.3V.

LilyPad Coin Cell CR2032 Battery Holder (switch wearable CR2032 holder)
Description:

Sure, your flashing, chip-tune playing t-shirt is really cool at the party... but at some point you need to turn it off. And yes, you could just pull the battery, or maybe you've even sewn a LilyPad slide switch in-line. Wouldn't it be nice if there was just a switch on the battery? Well look no further.

This LilyPad Coin Cell Battery Holder has a small slide switch installed on the board, in-line with the power so you can shut off your project and save batteries. This slide switch is the same as is found on the LilyPad slide switch board, so it's not easy to accidentally turn off or on.

Just like the original Coin Cell Battery Holder, this simple board holds a 20mm coin cell battery (such as a CR2032) and gives you 4 connection points (two positive and two negative) for sewing into your project.


Package Includes:

1 x LilyPad Coin Cell Battery Holder CR2032 Battery Mount Module

LilyPad Power Supply Module AAA Battery Step up to 5V Converter (wearable AAA battery holder)
Description

A small, but mighty power supply. This board was designed to be as small and inconspicuous as possible. Pop in a AAA battery, flip the power switch, and you will have a 5V supply to power your LilyPad circuit. Good up to 200mA. Short circuit protected.

This board has AAA battery clips but can use an input from 1.2V to 5V.

LilyPad is a wearable e-textile technology developed by Leah Buechley and cooperatively designed by Leah and SparkFun. Each LilyPad was creatively designed to have large connecting pads to allow them to be sewn into clothing. Various input, output, power, and sensor boards are available. They're even washable - but be sure to remove the battery!

Relay Board (KT relay kit)
Product Description

This is a versatile relay board kit that can easily be configured via jumpers and trimmer potentiometers to do a range of tasks.

Most sensor and switches can be connected to the input of the board and the trigger level set for the input device. This can be inverted if required, then there is the option to feed this straight to the relay or a timer of up to 25 minutes can be used. Irrespective of the state of the invert jumper whenever the sense LED goes from off to on the timer restarts.#

The board can run off any voltage from 4.5 to 6 volts.

The output cans switch DC or mains.

This datasheet details what the board does and how to use it along with some worked examples. A more detailed set of information including the build instructions & how to configure the kit can also be downloaded.
