Free Essays on HNC

Report As a feature of my HNC I was approached to Design, Manufacture and Test a circuit that would control both traffic lights and engine arranged on a model of the Kincardine Bridge. The detail I was given was that the circuit board could be no greater than 100 x 160mm and could cost close to  £50. Considering the detail I looked for parts I would use to build the circuit ensuring the cost was under as far as possible (the all out expense was  £42.99). The second undertaking I attempted was to plan a board inside the necessary size (the last size was 89 x 74mm) yet I ran into issues with the structure in view of this there was an aggregate of 20 plans before the board was fit to be fabricated, a portion of the issues are recorded beneath. SIL Reed hand-off pins were an inappropriate size Earth associations were absent LED’s were over-lapping The pins on the 7406 were associated the incorrect path round When the PCB was structured, the board was then made. The assembling procedure can be found in Appendix page 2'. The following stage was to test and populate the board, progression testing was finished by utilizing a multi-meter to check for open and shortcircuits and afterward hand patching all the parts set up. The populace procedure took me around 3 hours rather than the 2 hours arranged as I needed to de-patch my wire joins as they were not of a worthy norm. The last procedure was to test the completed PCB, this was finished by testing the yields on the load up as they all worked first time I had no additional issue discovering/troubleshooting to do. End As the circuit worked first time I demonstrated that I would be fit for experiencing ventures like this later on. The primary purpose behind the circuit working was the measure of time I spent at the structure procedure. This would set aside organizations cash, in actuality, as there would be no misuse of materials. I additionally feel that my venture aptitudes are improving, as there is a major contrast wager...
