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 9

I have managed to get most CAD parts finished by this week and will continue to get them done over the weekend. On Friday I got to 3D print the test lamp head. It worked alright but needed many improvements which I recorded in my document. I am also working on the Pseudo coding (like a plan of the code) which will help me to do the actual project coding. Next week I hope to print and cut out all the required parts and be working on the coding.

This week I've been working hard to get the CAD done for all my parts. During class time I began working on the programming side including a variable table and pseudo code. I will also need to make a circuit diagram for the level train crossing. Later this week I will work on a flow chart and start programming the actual thing.

WEEK 8

Unfortunately I was away for the rest of the week, but was able to work on CAD for the project at home. I also attempted to get my train bridge model 3D printed to test. Hopefully next week it will be ready.

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.

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.

This week I began designing the level train crossing on CAD and confirmed the dimensions of the train track. My teacher suggested the idea of routering out the railway into the base platform. It is a great idea as it reduces setup costs and makes the assembly process much simpler (which is what I aim for). The bridge may be harder to implement into the track but I'm sure it will be possible to by maybe having a couple guide holes for the plastic bridge to sink or clip into. I will continue to work on this as well as fix up areas of my document where information or calculations are missing.
