One Chip AM Radio
This is a complete AM radio for the standard broadcast band, most of which is on a single IC. Other components, such as the coils and variable capacitor to make a finished radio, are included. The IC is the RF amp, detector and AGC circuitry. The IC's output drives a two stage, transistor audio amplifier and 3" speaker. Operates from 9 volt battery. A good kit for beginners to see and build.

DC Motor Speed Controller
Vary the speed of DC motors the very best way with this kit. Gear boxes can be costly and series resistors may cause stalling. This circuit delivers the voltage to the motor with pulses and the speed is controlled via pulse width modulation (PWM). The speed control is a potentiometer, for DC motors up to 100 Volts at a maximum of five amps.

Variable Power Supply
A very basic power supply that can be adjusted over a range of about 1.5 to 35 volts DC. If you add a heat sink (included), you can run it as "hot" as 2 amps output; otherwise about 60mA @12 volts. This is a text book circuit using an LM317, which is a 3 terminal regulator in a TO-220 package. Input can be either AC or DC; DC input must be at least 2.5V above the required voltage output. You could use a surplus transformer from 12 volts up for input

PIC (programmable IC) PROGRAMMER
An entry level programmer and terrific educational aid. The 16C84 micro-controller from Microchip Technologies has become very popular with hobbyists and beginners. Does not require U/V light to erase programs; programs are erased electrically and the chip used repeatedly. This kit includes all software and hardware needed to begin programming; a full manual is on disk. Connects to an IBM-PC parallel port, connector included. Nine volt transistor battery operation.
No. 80-810 PIC Programmer kit.
YDI Price $49.90

PICmicro® Programmer/Experimenter
A Learning kit. This may be the best self-teaching/learning kit for a PIC (programmable IC) that we have in the line; and yet it is not expensive. Kit assembly is easy and any moderately experienced kit builder can put it together in an hour or so. Once built, a terrific educational system is at your finger tips. The kit connects to the the serial port of a PC (you supply a 9 pin straight through cable). You immediately program the PIC using the user interface software provided and the software runs, flashing LED's on the board in a definite sequence. Now you learn how to change the program to change the sequence. A 45 page manual and software is easy to download (free) from an internet page. It will take you through the process of learning programming of PICs. And how to use inputs and outputs to switch the LED's. The circuit uses the new Microchip® 16F628 and learning about it will teach you how to use any PIC in that series; and the basics for programming PICs in general.
