78XX Regulated
Power Supply
This circuit can be made into a regulated power supply for voltages
from five volts up to twenty-four volts. The user must add any of the standard
78xx TO-220 positive voltage regulators (7805 or 7806 or etc...thru 7824) and
the voltage will equal which ever part you select (the last two digits of the
number indicates voltage; 7805 = five volts etc.) .
You Input AC or DC (unregulated) about three volts greater than desired output
voltage; complete instructions included. The 7800 series outputs up to 1 ampere
typically. LED indicator and onboard on/off switch. You could use this with
a junk box AC or DC power supply or supply your own transformer etc..
Note: Consider the Philmore transformers: no. TR121
for 12 volts or no. TR241 for 24 volts. These are 110 to120 volts AC transformers
and the output is center tapped. Both are rated at one ampere.

This is not quite a complete kit; the package contains the three key parts for a PIR detector (personal infrared detector). You get the PCB mounted Fresnel lens, a PIR movement sensor and the Integrated Circuit that we use in the full kit (No. 80-300). Included are eight pages of documentation notes and circuits to show you how to proceed. No. 80-620 Detector Parts

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.

The idea of an electronic dice game of one kind or another is almost as old as glaciers. But this one is very clever and includes software on a floppy (for the IBM PC) plus a huge manual describing how such things work, software for other projects etc.. This may be the most educational kit in the line. No. 80-710 Programmable Dice kit |
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 (at)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 No. 80-680 Variable Power Supply kit |

With each advance in personal computers, a surplus of unwanted older machines increases, either at give-away prices or you may have one sitting on a shelf. Thus you can have a low cost, sophisticated "dedicated controller" to turn on or off devices in the home or lab or radio shack etc. The circuit includes eight relays controlled with (included) software for either DOS or Windows 3.1. Connects to the parallel port of any IBM-PC. No. 80-740 Relay Board kit |
Three Light/Dark Activated This kit is one of our three separate circuits in one; three separate PC boards etc.. This one will give you both useful circuits and experience in different approaches, circuit-wise, to doing the same thing; controlling a device with a change to either light or darkness. Each kit is equipped with a relay rated up to 240VAC (at) 5 Amps. You may either turn "on" or turn "off" the controlled device. A good kit for the student learning electronics.

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. |
117 Volt AC Relay Board Many electronic projects use a low voltage circuit, i.e. timer, light sensor, dark sensor, temperature sensor, movement detector etc., and output a signal when a certain predetermined event occurs. This signal is often a rising or falling 12 volt pulse; but then what do you do with it? You use it to control a relay capable of handling up to ten amps (or five amps 240VAC). The circuit includes a DPDT relay with a life expectancy of about ten million cycles. Be sure to build this circuit into a suitable case, so not to be exposed 110V AC connections.
