Our learn to solder pack is the ideal low cost solution for teaching soldering in the classroom/after school club. The pack provides all of the parts and PCB's required for a class size of 25 and also includes a 9V battery for testing purposes. Each pack comprises; 25 x PCBs, 100 x 100 ohm resistors, 25 x LED's, and a 9V PP3 battery.

We have also produced a step by step guide to soldering, which covers; equipment, solder, tinning & cleaning, soldering in 8 steps, de-soldering in five steps, wire preparation, examples of good and bad solder joints, basic PCB repair, resistor information, LED information, full step by step build information for the kit, and how the learn to solder kit works. This guide covers everything that you might need to discuss with students and can form the basis of your lesson plan.

Using the kits and the step by step guide, each student will solder four resistors and one LED to their PCB before pressing it to the terminals of the 9V battery to check that their board works. Using the guides they will be able to examine their own work and troubleshoot problems. The battery pads on the PCBs have been shaped inline with the battery terminals on a PP3 battery making it straightforward to see which way around it should be placed on the battery.

Learn how to harness the energy of the sun in your Electronics and Design and Technology projects with our new Solar Power Starter Kit. With this kit it is possible to build a simple solar charging and power supply system for a variety of useful low power devices.

As of 2017, renewable energy accounted for more than 25% of energy produced in the UK for the year. Environmental targets are such that this is set to increase year on year. Solar power is already a key player in the renewable energy market and there is the potential for it to grow much larger still. It has been estimated that covering just a fraction of the Sahara Desert in solar panels would provide enough electricity to power the energy needs of the whole world!

The Solar Power Starter kit itself is a simple kit to build and understand. Once the kit has been set up and placed in direct sunlight the batteries will begin to charge. If the light level is insufficient to facilitate charging, the diode prevents any of the charge held in the batteries from discharging back through the solar cell. The supplied switch enables you cut power to the kit that you are powering for greater recharging efficiency.

If used with the included Kitronik LED Desk Lamp Kit, for example, fully charged batteries will provide light for up to 17 hours, more than enough for a little light reading.

Note:

• This kit requires assembly and some soldering.
• The kit does not contain any connecting wire, you will need to use wire like Multi-stranded Wire.

Features:

• Harness the energy of the sun and add simple solar charging and power supply to your low power devices.
• Learn about renewable energy and how simple it can be incorporate into your designs.
• A Small Signal Schottky Diode is supplied to protect against accidental discharging of the batteries through the solar cell.
• Examples of Kitronik kits that can be used in conjunction with the Solar Power kit are;
• 2155 5V LED Desk Lamp Kit-Included with the Solar Power Starter Kit.
• 2157 FM Radio Kit V2.0.
• 2165 Mono Amplifier Version 3.0.

This kit can be used to make a shed or room alarm when mounted on the top of a door, drawers or any other object with a moveable opening. It can also be used by replacing the micro switch with a magnetic door contact.

A micro switch acts as a trigger mechanism and is armed / disarmed by a separate sliding switch. The door's movement is detected by a micro switch mounted onto a door or object with a lid. A timer provides an entry delay during which the system can be disarmed by the slide switch, whilst a separate timer silences the alarm after two minutes. Both of these timers are implemented via a 556 dual timer IC.

The alarm can be further enhanced by using a simple key switch for arming / disarming or by replacing the micro switch with a magnetic door contact switch to activate it. The board, battery pack & buzzer can be placed into a box designed by the student.

Features:

• Can be enhanced with a key switch to arm/disarm.
• Can be enhanced by replacing the micro switch with a magnetic door contact switch.
