Exam Revision GCSE 2013
Section A of the exam paper has the following context this year ..
“Designing an electronic device that could be attached to an item and would help to locate the item if it were lost.”
You should consider the block diagram ;
Microphone — Amplifier — Latch — Astable — Buzzer / LED
or replace the Latch with a Time Delay (Monostable)
You should revise Op Amp as an amplifier (P41 AQA Revision Book available from D+T Technician Store on D Block). You should also be familiar with Thyristors (Latch), Monostables and Astables.
In terms of casing it should be suitable for mass production so consider vacuum forming or injection moulding.
Consider that the device should be compact, robust, easy to attach, lightweight and cheaper than the product it is to be attached to!
GCSE / GCE EXTRA SUPPORT
All staff teaching GCSE and A Level Electronics have an “Open Door” policy and are always available to support students.
In addition to this we also offer this term a timetabled session on Wednesday lunchtime in D2.3 and Thursday lunchtime in D2.2 for students to come and work on coursework projects (Deadline April 1st).

REVISION SUPPORT
Our own revision resources are used by schools and students worldwide! We find it is easier to provide our own resources than use other published materials.
However our friends at KITRONIK have just released some excellent online resources that you must see. These include online tests.
We have also just purchased 10 Lonsdale Revision Books that can be booked by GCSE students wanting to complete extra revision. These are a supplement to the Electronics Revision Guide provided to all students at the start of the course.
