Infrared 4 x 8 LED Array Kit

Intended for CCTV

applications, this device

will illuminate any dark

area viewed with a CCD

camera, yet leave that area dark

to the naked eye. The array of 32 LEDs

provide considerably more illumination than that included

with CCTV cameras, with much lower cost and power

consumption than typical infrared lights. Dimensions:

Eight Channel Parallel

Port Relay Board Kit

Complete kit includes

circuit board with

eight output relays,

and software for

accessing through

the printer

port of

an IBM

PC or

compatible

computer. Each SPDT

relay may be individually

switched via the PC and is capable of handling a 3A load.

Eight board mounted status LEDs show relays state. Ideal

for controling lights and other electronic devices from a

PC. Because the hardware requirements are minimal

(80286 or later with only 1Mb of HDD space), this kit adds

practical use to obsolete computer equipment. Requires

external 12VDC, 800mA power supply and available

parallel port. Board dimensions: 5

Sweet 16 Tone

Decoder Kit

This kit operates great

through phone lines,

radios or scanners. The

decoder detects DTMF

data when each button is

pressed and sends a

unique voltage to the

electronics on the printed

circuit board which activates a circuit on or off. There

are 16 different touch tones, 12 of which are on a normal

phone; special key pads have four additional buttons (a, b,

c, d). This decoder gives an output voltage for all 16 tones.

If you want to use all 16, you can build your own board

with 16 relay and driver circuits on it, or to get fancier,

use a flip-flop IC to achieve a toggle effect or a 555 timer

to provide a timing effect. Uses a 9V battery not included

(#292-035). Dimensions: 2.2" x 2.8".
