Electronics Product Evaluation

Extracts from this document...


Electronics Product Evaluation In my GCSE Major project for DT electronic products, I wasn't pleased with my circuit, as however many times I tested it, it wouldn't work. However, I think the rest of my project went well. The first thing I did was design my circuit by computer. I based it on one published in Everyday Practical Electronics Magazine, although I made some alterations to it to suit my specifications. This was then etched in copper onto my printed circuit board. Next to be added were the components. After going down to Maplins to buy what I needed, I drilled holes in my PCB and soldered them in. This was one area where I had problems because sometimes as soon as the solder dried I noticed it hadn�t stuck onto the PCB and I had to do it again. ...read more.


Also I had to spend a lesson sanding the corners down. Something that went wrong during the making of my box happened when I was drilling holes for the switches. While I was drilling, the plastic snapped in half and flew off the clamp. I prevented this from happening the second time by drilling slower. The two push-button cases were made out of MDF, which I glued, sanded and painted black to match the other box. Making the casing was one thing in my project that went well, and I think they looked professional and attractive. It was durable and light as I had put on my specification. While I was making my product, I made some adjustments to my original idea. ...read more.


I would also redesign my circuit board - it could have been made smaller, and also I did the space for the thyristors wrong and one part of my track was unused. Another improvement would be to use less wiring on my components. Some of the wires were too long, and they always got tangled up. If my quiz boxes were to be produced industrially, I would have cut down the wiring, as useless wiring would be a waste of materials. Making a prototype for an electronic product was tough and very time consuming. I had to stay behind after school a few times to finish the soldering and testing. Although I didn�t get my idea to work like I had planned, I did learn a lot about circuit design and I gained experience in making and designing electronic products. ...read more.
