Grade 6 NST
Simple circuit to be soldered Resistor, Printed circuit board (PCB); battery clip, battery, mini jumper
Grade 7 Technology
Electromagnet kit 3 in 1 This kit has three parts:
a) Demonstrating electromagnetism,
b) A simple circuit also teaching learners to strip wire,
c) The soldering of four components on a small printed circuit board.  Ideal to introduce Gr. 7 to an electronic circuit
Series/Parallel (bulbs) Circuit in series and parallel.  Learners find it exciting to strip the wires and to cut them to size.  They place the components in the circuit and use screws and washers to ensure good electrical current and connection.
Series/Parallel (resistors) Resistors which are soldered in series and parallel 
Continuity Tester No soldering, only screws and washers. This kit makes it possible to see if the current is running through a specific component 
Electrical Motor Demonstrating a basic electrical motor.  Very exciting, especially for boys.
Grade 8 Technology
AND/OR Logic Gates No soldering needed.  This kit demonstrates the AND and OR logic gates taught in Gr 8 
Morse Code Once the electronic components have been soldered on the Printed Circuit Board, the learners can send Morse code messages to each other.  Morse code alphabet included.
Sonic Alarm
(can also be used for gr 9)
Circuit producing an output with a loudspeaker. The Sonic alarm sounds like an ambulance, or fire truck. 
Grade 9 Technology
(can be used for gr 7&8)
When completed, it demonstrates knowledge and understanding of how simple electronic circuits and devices are used to make an output respond to an input signal (e.g. resistors, LED’s, transistors, switches. Very applicable kit to apply in a mini-PAT 
Cell phone Charger with Solar Panel
(can be used for gr 8)
Mobile phone charger kit with electronic components soldered on a PCB. This gets connected to a solar panel. Ideal to demonstrate renewable energy
Solar Panel kit that replaces a 9V battery
(can be used for gr 8)

Many schools order our kits.  The teacher then guides the learners to assemble and solder the kits. All the kits use 9-volt batteries, which are expensive (R85 each). Instead of using a battery to check if the kits are working, one uses this 9-volt output kit to check if the alarm kit is working.  The kit includes a PCB, electronic components, wire and solar panel.

Dark Activated Light With this kit one saves energy, as the light will switch on only when it becomes dark. It can be switched on in the morning before work, but will light when dark.
Comparator / Operational amplifier Electronic components are soldered on a PCB.  Then an LDR (Light Dependent Resistor) or thermistor can be screwed in a terminal to demonstrate with an output how the thermistor is activated when heated or the LDR when a light is switched on
Light Dependent Resistor This kit can be used as an alarm for a jewel box or drawer.  When opened and the light falls on the LDR, the buzzer goes off 
LED Flasher This is a cheaper version of the alarm because it has one output only
Electronic Organ An electronic kit that has eight musical notes. One can play do ray me chords
Moisture Sensor Ideal kit when the mini-PAT requires a moisture sensor to help a blind person pour in enough water  
Bar graph
(measure charging and discharging of capacitor)
Visibly see the charging and discharging of the capacitor 
Running Lights / Electronic dice
(advanced soldering required)
Activates multiple LED’s with random unpredictable outcomes (dice).  When a short circuit is soldered in, the kit becomes running lights, useful to draw  attention (to attach to your bicycle) 
(advanced soldering required)
Add on to the sonic alarm 
FM Radio
(advanced soldering required)
Solder your own FM radio that will even play while hiking 
Grade 10 Science
Electrical Motor Demonstrating a basic electrical motor
Cordless Microphone This kit breaks into FM Radio (around 88 MHz) within a radius of 25 metres.  Learners can then enjoy themselves singing or talking on the radio
Time constant

Solder these components on a PCB and clearly see how the capacitor charges and discharges.  You can even adjust the current and use a stopwatch to enable you to draw the graph of the charging and discharging
