| FUSE TESTER PROJECT FOR SUMMER SCHOOL |
This project was devised for summer school at Highcliffe School in 2001. All students were about to enter year 7 and completed the project within 5 hours.
The design is basically a 3mm sheet of acrylic measuring about 160x80mm bent into a shape to accomodate a PP3 battery and also act as a stand. The front can be shaped into any theme you want to follow. We used cartoon characters from the internet using Google.

Circuit diagram of fuse tester, couldn't be simpler really. I gave students the option of LED's, buzzers or both. The buzzer draws around 10mA and the LED's about 18mA which is low enough to test even a 50mA fuse!

COMPONENTS
|
|
|
|
Buzzer, 35-0245
|
|
Above is the buzzer used in the project. Rapid sell it but it's a bit expensive. You can use any buzzer that works from 6 to 12 volts. A cheaper alternative is shown below.

|
Buzzer, 35-0100
|
| Below is the 20mm fuse holder used which has 1.5mm PCB connections and a 3mm fixing hole in the centre. |

BASIC STAND SHAPE
|
|
There are 3 bends that serve to form the stand and the holder for a PP3 9v battery. We used a strip heater and wooden formers to get accurate bends. It helps to bend slightly further than 90 degrees so the battery is gripped tighter.You can also drill a hole near the top centre and hang it on a wall.
Below is the drilling template for the fuseholder.
