I started off this week researching into what servos are and their purposes. We then tested out how an LDR and Laser pointer could be used as a train detector. My setup worked well but I don't think I will use it due to the laser hazard and the bulkiness of it (rather be concealed or small). I am on track to getting my testing done and I can prototype the ideas from it to be in my train crossing plan.

I have still been working on modelling and CAD all the parts of my design. I have tried to design them so that they are easily assembled with as least glue as possible. I brushed over a bit of my coding, variables and circuit diagrams for the final product. They still need a lot more work to get finished. The CAD is almost complete, just fixing up versions to improve the design of the part (e.g. the night light lamp head needed many changes for its design such as a better lamp cover holding mechanism, greater light (LED) angle, larger holes for sensor and aluminium pole, etc.). The base platform is pretty much done, just has to be adjusted every time a part is changed that affects its position on the board. I am really hoping to get all parts cut and printed out by this week, this allows me to do the rest of the programming during the holidays when I get more time to.

Week 7

I was able to get my parts list and design pretty nailed this week. I only just got to CAD'ing which will likely to continue on next week. My plan was to get onto the coding soon but due to other commitments I will fall behind schedule a bit so will have to adjust my plan accordingly. I also had another thought on the parts list is to just use the hall effect sensors instead of the combination with IR sensors thought of previously. This will not only reduce costs, but make it look and work more effectively, hence there are less parts for failure and errors.

Today I kept working on the level crossing platform's CAD'ing by getting the board's dimensions measured and designed in. I also began designing the 3D printed bridge which should slip into the board nicely and join into the railway track. I will not have as much time this week so will try my best to get as much of this done, will aim to get stakeholder feedbacks and then move onto the programming (planning and coding) side of the project.
