Unipolar Stepper Motor Driver
tn_cps179.jpg
Description: This kit is a very useful circuit for driving 5, 6 or 8-wire unipolar stepper motors. It can operate either freestanding or PC-controlled. The circuit and stepper motor may use separate supply voltages. Four high current IRFZ44 MOSFETs are used at the output. The motor can either be stepped by the internal, variable oscillator or by external 5Vp-p pulses. The direction of rotation can be set with a switch. This innovative circuit only uses standard CMOS ICs 4013, 4030 and 4093. Full explanations are given.

Specifications:
  • Supply Voltage: (kit) 7 - 12Vdc (stepper motor): 8 - 35Vdc
  • Supply Current: (kit) 0.1A max. (stepper motor): 6A max. per winding
  • Dimensions: 46 x 75mm, 25mm height

Servo Motor Driver using PIC16C71 1-4
tn_cps102.jpg
Using a PIC 16C71, a crystal, 8 resistors & 4 capacitors this kit will independently control up to 4 servo motors. We do not supply the potentiometers or servo motors. (a Futaba FP-S148 was used in the tests.) 5V DC power supply required. Full instructions provided.
Servo motors are used in radio-controlled models (cars, planes), robotics, theme park special effects, test equipment, industrial automation. At the hobbyist end of the market they are small, compact and relatively inexpensive at around US$20. The motors themselves are black boxes which contain a motor, gearbox and decoder electronics. Three wires go into the box; 5V, ground and signal. A short shaft comes out of the motor which usually has a circular interface plate attached to it. Most servos will rotate through about 100 degrees in less than a second according to the signal input. This kit will control up to 4 servo motors simultaneously. (CPS102)

Bidirectional DC Motor Speed Controller Kit
tn_cps166a.jpg
Description: This kit allows controlling the speed of a DC motor in both the forward and reverse direction. The range of control is from fully OFF to fully ON in both directions. Normally, switches are used to change the direction of rotation of a DC motor. Change the polarity of the applied voltage and the motor spins the other way! However this has the disadvantage that a DPDT switch has to be added to change the polarity of the applied voltage. Now you have two things to control the motor – a direction switch as well as the speed control. Also, it is not a good idea to suddenly reverse the voltage on a DC motor while it is spinning. It can cause a current surge that can burn out the speed controller. Not to mention any mechanical stress it can cause as well. PCB size: 93mm x 42mm (3.625 x 1.625 inch)

IR Remote Control and Decoder IC
tn_cps92.jpg
This Kit uses a commercial 14-pin remote control unit to put an active low signal onto one of 14 pins on a decoder IC. That is, when a RC button is pressed, the pin corresponding to that button on the decoder IC goes low. Normally, each of the 14 output pins is high. It is up to the user to use this information in their own circuit where remote control is required. For example, to control up to 14 relays or to control the movement of a robot. We supply all the necessary extra components required for the decoder IC to function properly. No PCB is supplied. It is up to the user to breadboard their application then make their own PCB. A sample application/test circuit is provided. A 330Ω resistor & LED are supplied for testing the active low on a pin in response to a button press. (CPS92)

Each board has a PCB-mounted switch to convert the circuit from light to dark switching and vice versa. There is nothing original in these circuits - they have been around for years.

LDR Kit 1
tn_cps79a.jpg
Uses two transistors in a super-Darlington setup. By reading about all three Light/Dark Kits you will be able to decide which circuit is the best for your particular application. If your application is in very bright or very dark conditions then you can easily experiment with different resistor values to get better control over the switching range you need. There is nothing original in these circuits. We have taken them from published material (see end of this paper for References.) But we have redesigned them each onto similar PCB's to allow easy comparison. And in addition a light/dark option has been incorporated into each. We say 'light/dark' because each circuit has a PCBmounted switch on-board. In one switch position a light-to-dark transition will activate the relay. In the other position a dark-to-light transition is required. So you can use the light falling on the detector to switch on a normally off circuit, or switch off a normally on circuit. (CPS79A).

Touch Switch
tn_cps137.jpg
You can turn on almost any electrical device with this
switch, and the switch auromatically turns off a short time
later. As you will see you can determine how much later –
less than a second to over one minute – just by changing
the value of one resistor.
The kit uses a 12V relay to do the switching. It is rated at
250V/12A. The Dinkle brand 3 pole terminal block is also
rated and approved for this voltage and current. So the
switch can be used for switching AC as well as DC. It is
best to use a 9V – 12VDC regulated or unregulated
plugpack for the power supply. Do not go over 15VDC
input.

Dual HI / LO Switching Relay Board (Kit)
tn_cps156_kit.png
Description: The kit is based around the ULN2003A IC, a 7-channel high voltage, high current relay driver. The inputs are TTL compatible so they can be connected to 5V. LO 0-0.8VDC. HI 2.4V - 12VDC. Operating voltage: 12V DC. The relay will be operated when either the LO input is low (0 – 0.8V) or the HI input is high (2.4V – 12V.). Two 12V relays, coil resistance 400 ohm are used. It is rated to switch 250VAC at 12A. However, because of the PCB track thickness and width we do not recommend using the relay to switch more than 5A. PCB size: 2 3/4"x1 3/4"

QUAD TRIAC SWITCH CARD
Click here for specs, downloads, and more pictures.
Relays are usually used to switch AC voltages by means of an electronic control because of their simplicity. However, when switching occurs too frequently or too quickly the life time of the contact points is shortened considerably. This can be solved perfectly by replacing the relays with a triac. Using optocouplers, the entire interface network remains electrically isolated from the voltage that has to be switched.

Forgotten to turn off the tap, leaking washing machines, water level dropping in your aquarium, rain tank or water tank suddenly dry or over flowing, water in your cellar, etc. Such situations are often the cause of trouble and financial burden. Prevention is better than cure. So use this fluid detector. This multifunctional device is easy to use in a variety of applications : 1) LED control of set fluid level : LOW, MIDDLE, HIGH ; 2) Controller : the relay automatically switches a pump and/or valve to keep the fluid level between the LOW and HIGH marks ; 3) Alarm : if the sensor detects a level which is too high or too low (selectable), the relay will operate a bell or other alarm device.
