MAKING A VIBROBUG
MINIATURE 3V VIBRATING MOTOR
In the January update we reported on a project that we were doing to design a bug to that could be cut from 3mm Perspex and would scuttle across the table powered by a vibrating motor.
Miniature vibration motor measuring only 12mm long x 6mm diameter. Coreless motor design, rated at 3V nominal.
After a number of revisions we now have a final vibro bug design. Schools can download the data (see quick link) and save money by cutting their own vibro bug from a sheet of Perspex.

HIGH POWER STEREO AMPLIFIER KIT Amplifier kits have been a popular choice with school D&T departments for many years. At key stage 3 where there is a limited budget the choice generally tends to be limited to a mono amplifier or one of our low power stereo amplifiers. However on a one off GCSE product design project the budget becomes less of an issue as students become more concerned with how the kit performs. If you are looking for performance then this kit has to be the choice. The sound quality and volume are comparable to a car stereo or portable ghetto-blaster. This is achieved by using a pair of full range speakers which have an excellent response from low bass frequencies to high treble frequencies. These Product specification - Two high quality speakers - Output power 15W per channel - 12V, 2A Wall block PSU - Volume control - On/ off switch
high spec speakers are combined with a circuit that can drive each of them at 15 Watts giving good quality audio at a loud volume. The higher output power means that it’s not practical to run the amplifier off batteries, instead the kit is supplied with a wall block power supply. The kit is available in three versions, as a full set with the power supply, speakers, components & PCB and either a jack lead or an iPod lead. If you already have your own speakers then it is possible to just buy the components and PCB. For full purchasing information see opposite page and below.
- Blue power LED - iPod / jack lead - PCB dimensions: 77.5mm x 59mm. - Four mounting points are available, one in each corner.
HIGH POWER STEREO AMPLIFIER This amplifier kit can output up to 15W per channel into a pair of high quality speakers. The kit is capable of producing a very loud, high quality stereo sound. The kit includes all the parts required (plug in power supply, two speakers, PCB etc) to build your own amplifier for use with items such as MP3 players. The kit is available with either a 3.5mm jack lead or an iPod lead. It features a power LED, on / off switch and volume control. www.kitronik.co.uk/quicklinks/poweramp Description

It is 65 mm, 5W full range speaker whilst the circuit board won’t drive the speaker at its full potential it will still sound a whole lot better. Attributes: - Moisturised cone - Metal basket

CHOOSING A PSU FOR YOUR LED STRIPS
WALL MOUNT PSU, 12V, 5A
LED strips are very easy to use, but you need to make sure the power supply has sufficient capacity for the length of LED strips being used. As all the colours of LED strips take about 400 mA per meter, the longer the length of strip the bigger the power supply has to be. To save you doing the maths below is a table showing the maximum length for each of the power supplies. We have even added a new wall mount power supply which is good for fixed installations of a couple of reels of LEDs.
This wall mount power supply is perfect for use with our LED strips and can power up to 12.5m. The unit has mounting lugs allowing it to be secured under kitchen cupboards etc. On the mains input side there is a pair of tinned bare wires which can be wired in to a plug or can be used in a permanent installation. The power supply has over voltage, short circuit and over temperature protection.
