KITS - GAMES, & FLASHER PROJECTS

LED Dice with Slow-DownThis is an excellent kit for use as an intro-duction toelectronicsand circuitanalysis.Seven LED’sarranged likea real dieface. Push the switch and the die rolls andthen slows down and then stops. Uses aningenious circuit design to minimize partscount. Uses a 555 and 14017 integrated cir-cuits. Includes plastic case; battery opera-tion.

No. 80-030

Programmable Dice

The idea ofan electronicdice game ofone kind oranother isalmost asold as gla-ciers. Butthis one is veryclever and includes software on a floppy (forthe IBM PC) plus a huge manual describinghow such things work, software for other proj-ects etc.. This may be the most educational kitin the line.

Two-LED Flasher Kit

The Two-LED Flasher kitis a very basic kit and itdoes nothing more (orless) than blink one LEDand then the other. Theback and forth flashing isreminiscent of a railroadcross signal light, andmany times it is used bymodel railroaders for that purpose. Simple bi-stableoscillator circuit; operates on 3 VDC and two AACells will last for weeks. You can change out someof the components for faster and slower, details inthe instructions. Two-LED Flasher

5 LED Multi-Sequential Flasher

Flashes five, verybright LED’s in anyone of seven, user-selectable, patterns.A COB (chip-onboard) IC makesassembly very easy; the chip is suppliedpremounted on its own board and a mother-board contains the entire circuit. Operateson 3 volts DC, battery holder is included.Continuously repeats a sequence whenpower is supplied.

No. 80-375

5 LED Sequential FlasherThe circuit flashesfive LED’s insequencerepeatedly untilyou turn it off.Flash rate isuser adjustable.The circuit usesan IC chip-on-board which youwill then mount on the included motherboard;battery holder is included. Powered by a 3 Voltsupply or battery; good for a child’s toy or forthose “high-tech” looking special effects forstage plays etc.

Xenon Tube Flasher (6 volt)

Bright, variableflash ratestrobe lightcan serve as abeacon, signaletc.. A smallcircuit, easilytransported for camping. Uses could includephotography, spooky fun house etc.. (Try turn-ing it on with the VOX switch No. 80-130).Flash rate may be varied to between 1 andfour flashes per second.

No. 80-162

Usually more practicalthan a battery operatedstrobe, runs on stan-dard house current. Theflash rate is adjustablefrom about one everythree seconds to aboutthree per second. Usesare as signal beacon,trade show kiosks, dis-cos, etc.. Very bright flash can be seen for miles at night,like those on airplanes. AC cord and plug not included.

110 Volt AC Strobe Light Kit

For Fun, C.O.B. Project Kits C.O.B. means “Chip on Board”; and most of the electronics are inside a tiny, application-specific chip, or integrated circuit, on a PC board. These circuits are fun butwon’t be much of a challenge or education as they are so simple; you add a battery and the circuit is ready to go.

No. 80-940 - Ambulance, Fire and Police Sounds.Sirens and machine guns and more; great for kids toy!

ION GeneratorAre there somehealthful positivebenefits caused bybeing in an envi-ronment that con-tains negative orpositive ions?Some reports sug-gest a wide rangeof benefits. Thisgenerator can be set up to generate either negative or posi-tive ions; the builder’s choice. Operation is from 117 Volts ACpower line. You will need to find a case or box for the finalassembly, about 2” x 4-1/4” and an inch depth; and an ACpower cord from an old lamp (or buy new). You can actuallyfeel the flow of ions from the unit.
