firmware K148 (T1) - Simple Photographic Time Firmware Chip.
 
This timer was developed after an enquiry from a hobbyist who wanted a simple 60 second timer when printing photographs. At the end of 60 seconds a beeper or buzzer would sound to indicate ‘times up’. After some discussion about other photographic uses it was decided to add some extra ranges as well. We also decided on an open collector style output rather than an on-board buzzer. This enabled the kit to drive other
devices such as relays, making it more useful in other applications. Please note this item requires the CPS148 to work. This is only the firmware chip for CPS148.

MULTIFUNCTIONAL COUNTER MODULE
 
Ideal for counting people or parts, for keeping scores, etc... The HOURS:MIN and the MIN:SEC functions are also very practical (displays 23:59 & 59:59). A built-in oscillator makes it possible to time intervals without making use of an external oscillator (clock function). Counting impulses (addition & subtraction) can be given both through push buttons and the counting inputs. A memory function constantly compares the current value with a preset value and activates an output for as long as both are equal. (VM107)

Big PIC Clock kit
 
The Big PIC Clock is based on a PIC16F84 microcontroller (uC.) The software in the uC allows for very accurate timekeeping. For visibility at a distance it uses 2.3"/57mm super large, hi-efficiency red LED displays for the hours and minutes and smaller 0.56" LED displays for the seconds. The circuit incorporates a dimming feature so that at night the reduced ambient light is sensed and the display is dimmed. The software program including a time adjustment mode can control the clock to a few seconds a year.

Square Wave Oscillator LN/NE555 (inc box
 
Simple circuit to generate square waves of approximately 1Hz 10Hz 100Hz 1KHz 10KHz & 100KHz. A square wave generator is one of those pieces of equipment that has many uses in the workshop yet few hobbyists actually have. This simple kit, based on the popular 555 timer IC, generates six preset frequencies from 1Hz to 100khz. It has an operating voltage range of 5 to 18VDC and even provides visual indication of the output. The kit is constructed on a single-sided printed circuit board (PCB). The PCB size: is 78 x 50mm (3.1" x 2") and will mount on a small plastic 'Jiffy' box. (CPS111)

Oscillator Building Blocks
 
Build and experiment with astable, monostable and SR flip-flop multivibrators(MV)on one PCB. 6 LED's & 9V battery-powered. Good introduction to electronics. Oscillators are everywhere in electronics. They are a basic building block upon which the whole structure of electronics and computers is based. This kit looks at the 3 basic types of multivibrators. They are designed to have zero, one or two stable states; the astable or free running MV, the monostable MV (also called the one-shot) and the flip-flop or bistable In the flip-flop MV a trigger pulse or control signal is required to change from one state to the other. MV's use regenerative (positive) feedback; the active components present within the circuit operate as switches being alternately cut off or driven into saturation. These circuits have now largely been replaced by timer ICs like the 555. (See CPS111.) However, a basic understanding of them is still essential since they are still used in many circuits.(CPS9)
