K5
- Stairway To Heaven
A game of skill to turn on the Stairway
of 6 LEDs as the bi- colour LED flashes. Introduces you to several electronics
basic circuits with a surprisingly difficult game to play. Box included. Good
introduction to electronics. 9V battery.
K6
- Roulette LED
Electronic game. Ten LEDs in a circle.
One LED is turned on at a time to simulate the spinning of a roulette ball around
the wheel. Uses voltage controlled oscillator circuit. 'Ball' gradually slows
down and stops on a number. 'Ball' speed can be adjusted. Uses 9V battery.
K37M
- 5 LED Multi Sequence Flasher
5 ultra bright LEDs flash in seven
patterns. Cycle through the patterns using pushbutton switch. When you find
the pattern you want operate the toggle switch to keep it flashing so long as
power is applied to the board. 3V operation. Chip-On-Board PCB. Motherboard
supplied to mount all components.
K52M
- 5 LED Random Sequence Flasher
Very small Chip-On-Board PCB just
15mm x 8mm. 3V supply. 5 LEDs flash in sequence. Push-on switch toggles the
flashing sequence on. A second push is required to turn the flashing sequence
off. Ideal for model railways. Tape up two 1.5V button cells with the PCB. Spare
COB PCB supplied. Good introduction to the electronics in today's toys and games.
Motherboard supplied to mount all components.
K69
- Single LED Dice
One of the most popular electronic
kits ever is the LED Dice. Now we have used the popular small micro-controller,
the PIC 16C54, to " roll the dice". All software
code is provided with complete comments so you can learn how to program
these devices for yourself.
K73
- Big PIC Clock
A 12/24 hour clock using a
PIC microcontroller and BIG 2.3" (57mm) high 7-segment displays.
Based on the kit published in Silicon
Chip, March 2001. Fully annotated source for the PIC is available here.
K104
- Music Box Engine
The electronic equivalent of a mechanical
music box. Tunes are contained in an IC. It is activated by light falling on
an LDR. It then plays a range of tunes. The kit can be placed anywhere you want
to hear a tune when light shines on it; opening a cupboard or drawer, music
box. Two music ICs and all components, including speaker, provided.
