Kit 38.
Timeout. Introduction to Micro-controllers Scan of PCB This kit introduces the Motorola 68HC705K1, an 8-bit 16-pin microcontroller first released in 1992. The Kit is a down counter from 60 or 90 seconds. with beeps every 10 seconds. Designed to introduce the very beginner to microcontrollers and how to code them. The on/off switch and pulldown resistors are all built into the K1 and are under software control. 9V battery powered. All the information about how to program these computers on a chip is supplied. Featured in Everyday with Practical Electronics, February, 1994. K39 - Full Duplex Fibre Optic Audio Link

We have made a stripping and heating machine to fuse the two-to-one Fibre-Optic T-connector and have designed a small PCB to mount the FO transmitter, receiver & T-connector to allow full duplex communication. 14 feet of 1mm plastic fibre optic cable and a connector to join extra FO cable is supplied. 12-15V AC or DC supply.Kit 40.
[PICTURE] Reaction Timer 68HC705K1 Scan of PCB Over the years there have been many logic circuits published for simple reaction timers - the logic shows which of two contestants was first to press a button after a sound or light stimulus or a question. However, none of them showed how many milli-seconds both the winner & the runner-up took to press their buttons. The use of microcontrollers demonstrates how software can replace logic ICs to give a smaller and much more versatile electronic circuit. The software is an extension of that already presented in Kit 38. The major change is the addition of a 4.096 mHz crystal for accurate time measurement. Pressing either button turns the unit on. The fastest ever previous response time (since the battery was connected) is displayed. Press again - '000' is displayed and a random 'beep' sounds within 4 seconds. The exact time when both persons press their buttons (if within 999 msec) is recorded and displayed alternately on the display. The unit will power down automatically after one minute. The off/on switch is built into the chip. 9V battery powered. All flowcharts & commented software code supplied. Featured in Electronics Australia, , March, 1994. Software Reaction Timer 85K

(Picture)Quite often the hobbyist needs to use a relay. The output of some device like a PIR has output pads for the alarm signal which must be connected to a remote switching device. Or sometimes we have a Kit to test which needs a relay connected to it. To fill these needs we have made two Kits which are just a relay, PCB and terminal blocks for the input/output signals. There are many relay pin-outs & drive voltages to select from. We have standardized on two 12V relays from Goodsky. Kit 43 uses a large electro-mechanical relay designed to switch 240VAC/5A. Kit 45 uses two miniature 1A relays.

K72 - 4 x 8 Channel IR Transmitter & Receiver
| US Funds | $63.25 |
| Canadian Funds | $93.50 |
(Picture Receiver) (Picture Transmitter) Control 8 relays using this IR Remote Control Unit . Over 20 meters in sunlight. Uses 2 high-powered IR LED's & latest IR detector/decoder from Kodenshi. Transmitter case, 8 miniature relays & all components provided. Uses paired encoder/decoder IC pair. Full instructions included. Four ranges set by jumpers.
NOTE: Nov 96. We have found that the latest batches of the SM5032B receiver decoder IC (date coded 9620 & 9630) do NOT work as the previous chips did. The problem has been traced to a change by the chip manufacturer. The two jumper-on option does not work. No jumpers on or only one jumper on still works OK. So this is now a 3 x 8 Channel IR Tx/Rx. The manufacturer says they will not be changing the chip at the moment.

A test program lights to flash an LED at different rates (plus all hardware resistors & LED) come with the Kit. A 16F84-4MHz PIC also included.
In mid-1997 Microchip upgraded the 16C84 to a 16F84. There was one small but significant programming change as far as the beginner is concerned.
- software is only for the 16C84 & 16F84 so no other programming options to confuse you.
- software can read, verify & load
- EEPROM space, program space & configuration fuses can be treated separately
- separate Erase command
- Test command to test the Programmer & cable connections
- Vpp (the programming voltage) is under software control
- 9V battery powered
- Microchip data sheets on the 16C8x on disk with the kit
- 16F84 programs made by other assemblers can also be used with this programmer
- full schematics, circuit explanation & documentation provided
This Kit was featured in Electronics Australia, April, 1996.
It is possible to buy cheaper 16F84 programmers but features rapidly drop off as the price goes down (for example, manual switching of programming voltage required, programmer cannot verify or read, software is minimal.) And without certain built-in safety circuits (buffer IC between PC & chip to be programmed) these cheaper programmers cannot be guaranteed to work on all parallel ports of all PC's.

K84 - Mains Power Relay Switch
| US Funds | $13.75 |
| Canadian Funds | $20.52 |
Many electronic projects use a low-voltage circuit to control the mains power supply eg. a touch switch, movement detectors, etc. In most cases the signal is brought out to a pad or terminal on the PCB. It is left up to the user to "use a suitable relay" to make the actual connection to the mains. Well this kit is the answer! It will take a +12V high or low going signal to switch a DPDT relay rated at 5A/240V. Both sides of the mains supply can be switched. A 5A fuse on one side is also included.

Acquisition System. It uses a MAX186 ADC. It all fits inside
an extended D shell case which plugs onto the parallel DB25
connector of your PC. It has 8 analog inputs, 4 digital inputs
& 4 digital outputs.
Kit 119. P16PRO8/18 if you just want to program
8 and 18 pin serial programmed PIC IC's using the same software
and circuit as Kit 96 below. Kit 121. Atmel 89Cx051 Programmer No special software
required other than a terminal emulation program. In Windows
these terminal programs come with it: Terminal (W3.11) or
Hyperterminal (W95/98). Can be used on any computer and operating
system. Kit 122. [PICTURE] Atmel AVR programmer. To program 20-pin
DIP - 90S1200, 90S2313, and 40-pin DIP - 90S4414, 90S8515.
Programs at 9600 baud. It will not program the 8-pin AVR devices
(90S2323, 90S2343).
Kits 124 & 125. Compact positive (K124) and negative (K125)
adjustable power supply +/- 1.5V to 35V depending on input
power source. On-board heatsink Kit 127
3 1/2 Digit Panel Meter. A double-sided
board designed to eventually replace Kits 2 and 34. Kit 129. [PICTURE] 4 Digit Up / Down Counter using an Atmel
micro-controller. The first in a series of counters using
uC's. This kits clearly shows how uC's can more than replace
a host of ordinary logic IC's. This is a single-sided PCB.
It will replace the old Kit 1.
Kit A15 - RF Transmitter & Receiver
Units The RF transmitter comes ready-made in
a case with a 12V battery & lanyard. It can transmit between
300MHz and 375MHz adjusted by a trimcap in both units. It
has a range of 30-40 meters/yards. The A5884 IC has 10 address
bits & 2 data bits. It encodes 12 bits of tristate information
& serially transmits it upon receipt of a low input on
one of the data pins. The decoder board comes with a decoder
IC. It must be built into a decoding circuit on the target
board. We have two kits in prototype stages which use this
RF Tx/Rx. A sample circuit showing how to toggle on/off two
relays (which will soon be released as Kit 82) is included
with the Kit. Kit A15 contains the Tx/Rx and the decoder IC
for you to use in your own circuits.
