Electronics Education

Electronics Education is a new website to support the teaching and learning of Electronics in schools. A wealth of information is provided to help in the purchase and use of tools and equipment, information on circuits and projects suitable for both GCSE and A level electronics. The circuits and projects have been made at KS3, KS4 and KS5, and actually work. A worksheet is provided for each circuit providing a diagram, bill of materials (parts list) with order codes and a brief description as to how the circuit works.

There are also a series of worksheets that can be downloaded.

OSRAM 64478 HALOLUX CERAM ES 150W 240V £8.94 A Dimmable 150W 240V ES clear Halolux Ceram lamp with an average life of 2000 hours. find out more		INA168NA-250 RoHS £2.15 (24 or fewer items) £1.91 (25 to 99 items) £1.67 (100 to 249 items) £1.42 (250 or more items) The INA168 is a high-side, unipolar, current shunt monitors Wide input common-mode voltage range, low quiescent current, and tiny SOT23 packaging enable use in a variety of applications. Input common-mode and power-supply voltages are independent and can range from 2.7V to 60V. Quiescent current is only 25ìA, which permits connecting the power supply to either side of the current measurement shunt with minimal error. The device converts a differential input voltage to a current output. This current is converted back to a voltage with an external load resistor that sets any gain from 1 to over 100. Although designed for current shunt measurement, the circuit invites creative applications in measurement and level shifting, the INA168 is available in SOT23-5 and is specified for the –40°C to +125°C temperature range. find out more		LM393N RoHS £0.14 (99 or fewer items) £0.11 (100 to 499 items) £0.10 (500 to 999 items) £0.08 (1000 or more items) A dual voltage comparator in an 8 pin DIL package.
