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.

This is a versatile relay board kit that can easily be configured via jumpers and trimmer potentiometers to do a range of tasks.

Most sensor and switches can be connected to the input of the board and the trigger level set for the input device. This can be inverted if required, then there is the option to feed this straight to the relay or a timer of up to 25 minutes can be used. Irrespective of the state of the invert jumper whenever the sense LED goes from off to on the timer restarts.#

The board can run off any voltage from 4.5 to 6 volts.

The output cans switch DC or mains.

This datasheet details what the board does and how to use it along with some worked examples. A more detailed set of information including the build instructions & how to configure the kit can also be downloaded.

The Kitronik Deluxe Rear Bike Light Kit is easy to build kit and is an excellent way to learn about the very popular 555 timer IC. The kit uses four ultra bright LEDs that can be operated in two modes; constant and flashing.

A key design aim of the kit was that it should conform to all relevant British Standard measures. Both the flash rate and brightness conform to British Standards for vehicle road lighting (2005), making it ideal for use as a rear bike light. Alternatively, it can be used as a night safety product or flashing eyes.

During testing we connected the kit to 3 x AAA batteries and ran it continuously. At 80 hours of continuous use the LEDs were still lit at full brightness. After 107 hours, although still lit, the brightness had dropped below the level at which you would want to use them. So, we estimate that with brand new batteries you could comfortably run the light for 2 hours of daily commuting for at least an entire month with the LEDs still at full brightness.

Features:

• An easy to build rear bike light project that conforms to British Standards for vehicle road lighting (2005) for both brightness and flash rate.
• Learn about the very popular 555 timer IC.
• The kit features 4 x bright LEDs.
• It has two operating modes; continuous and flashing.

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.
