General Purpose, 3-1/2 Digit LCD Panel Meter
Philmore DATAKit # 80-340
Uses the ATMEL AT89C2051 microcontroller, which comes already programmed with a clever and complex display pattern. The 30 LED’s follow each other about and finally flash and hold the star pattern for a moment. Or, you can download software (free) to set up your own pattern.Place in a window or on top of a Xmas tree ; the super-bright LED’s produce a very spirited holiday feeling. This is an excellent micro-controller learning Kit with full explanation of how the device works and drives the 30 LED’s. Operate with a wall adaptor at 9 volts and about 150 milliamps (maximum). A very nice kit. We suggest you also order a soldering tool kit to make this project. Click here to go to this item (# S540). Click Here For Picture Of Soldering Kit # S540.

PLL Experimenter Kit From KHz TO 185MHz!
Philmore DATAKit # 80-035
An exciting circuit, the PLL Experimenter kit may be used for making a stable AM or FM transmitter, a Signal Generator (from low kHz to about 185mHz), a QRP Ham transmitter, circuit diagrams for all of these are included. What you get is a very high quality PLL circuit module, with touch-tone style keyboard (to set frequency) and you will have to add the components for the circuits mentioned above. Crystals can be expensive; here is the answer. Not a beginners kit; intended for the serious experimenter, Hams or very advanced beginner. Operation from 8 to 12V DC; a nine volt battery is ideal. Fine tuning in 10 kHz steps. Extra room on board for added components. This circuit is really worth having! We suggest you also order a soldering tool kit to make this project.
