The MK484 Radio on a Chip
Code: MK484
Price: $3.41
Quantity in Basket: none
For use in the Three Penny Radio project. A 10 transistor tuned radio frequency integrated circuit with automatic gain control.
 



Battery Holder
Code: BATTHLDR
Price: $2.82
Quantity in Basket: none
For use in the Three Penny Radio project. Holds one AA size battery.
 



Solar Cell
Code: SOLARCELL
Price: $2.86
Quantity in Basket: none
Tiny Silicon Solar Cell For the laser communicator, or for powering the three penny radio. (You will want three for the radio.)

This tiny solar cell is 2 centimeters on a side.

They can be soldered, but we find it easiest to use transparent tape to stick wires onto the cell.

This makes a good sample for Silicon in your collection of samples for the Periodic Table of the Elements.

 



Three Tiny Solar Cells
Code: 3SOLARCELLS
Price: $6.38
Quantity in Basket: none
Three tiny solar cells, each 2 centimeters square. These are enough to power the Three Penny Radio.

Price: $16.94
Quantity in Basket: none
Sometimes you just want more power.
 



One Alligator Test Lead
Code: ALIGATOR
Price: $0.65
Quantity in Basket: none
These are brightly colored wires with alligator clips on each end.

They are used to quickly get an electrical project up and running, or to test different configurations of a project quickly and easily.

They can be cut and soldered into our radio projects to make attaching antennas and ground wires quick and easy.

 



Ten Alligator Test Leads
Code: 10ALLIGATOR
Price: $5.63
Quantity in Basket: none
Ten Test Leads.
They are so handy, you will want more than one.
 



Solderless Breadboard
Code: SOLDERLESS
Price: $8.85
Quantity in Basket: none
Solderless breadboards allow many of our electronics kits to be built without any soldering required, or with minimal soldering to attach leads to some parts.

This solderless breadboard has 63 rows of 10 connection points (630 connections) plus two power rails, one on each side. This allows plenty of room for combining projects on the same board, or for adding your own enhancements.

 



Printed Circuit Board
Code: PCBOARD
Price: $5.13
Quantity in Basket: none
This is the generic printed circuit board used in the Free SPace Laser Communicator project and the Solderless Breadboard projects.

It has room for a 20 pin integrated circuit (10 rows of 5 holes, arranged as 3 holes for parts and 2 holes for external connections).

There are two boards connected by snap-off tabs, so either two separate projects, or one larger project can be made using the same board. Similar to the Radio Shack part number 276-159B.

 



Simple Amplifier Kit
Code: SIMPAMP
Price: $13.48
Quantity in Basket: none
All the parts for the Simple Amplifier.

Small speaker (1.5 inches), Darlington transistor, circuit board, resistors, jumper wires, and battery clip.

 



Integrated Circuit Amplifier Kit
Code: ICAMP
Price: $17.34
Quantity in Basket: none
All the parts for the Integrated Circuit Amplifier.

Small speaker (1.5 inches), integrated circuit amplifier chip, circuit board, resistors, capacitors, jumper wires, and battery clip.

 



Digital Multimeter
Code: METER
Price: $11.57
Quantity in Basket: none
Digital Multimeter.

Reads 0 to 200 microamps at the most sensitive current scale, so this is a good meter for the photocell and other projects that need sensitivity. Also great for the digital thermometer project.

 



Digital Thermometer Kit
Code: THERMOMETER
Price: $22.84
Quantity in Basket: none
Everything you need for the Digital Thermometer Kit.

The multimeter, an LM34 Fahrenheit sensor, an LM35 Celsius sensor, two 180k ohm resistors, a 9 volt battery clip, and three alligator test leads.

 



Magnet wire
Code: MAGNETWIRE
Price: $8.73
Quantity in Basket: none
Sixty feet of 22 gauge polyurethane coated copper wire. The green insulation is easy to distinguish from the bare copper, so it is easy to scrape off just the right amount when building the Simple Motor project.

Also great for winding the antenna coil of the Portable Crystal Radio, and the perfect length for an antenna for the Simple Crystal Radio project.

This makes a good sample for Copper in your collection of samples for the Periodic Table of the Elements, especially if you sand off the insulation.
