TASKS AT HAND:

<-- Weeks Overview

Day 36
[ Preparing Files ]

Day 37 -->


1. Troubleshooting Laptops of my peers installing Ubuntu
2. Editing my Website


After a very informative Recitation with Dr. Neil, I sat for an hour or two to think of ideas regarding my assignment and how i plan to go about it. Went through softwares suggested by other fabbers like 123D Circuits and EAGLE and also different types of customised circuits online.

Day 37
[ Parallel Designing ]

Day 38 -->



1. Autorouted with different orientations keeping the customised board shape in mind.

I went at 11 and got free in evening around 6 because i had to walk from one corner to other and to other and back to Ashram,in which i even visited one Historical place in pabal.

Day 38
[ Photoshop Routing ]

Day 39 -->


1. Imported Indexed PNG to Photoshop for Routing
2. Developed 3 layer routing image-Trace | Shine | Cut (Cut wasnt needed-file size just fit in the FR board)
3. Manual routing according to shape.

The photoshop process was basically about using the brush tool to smoothen and curve the traces. I would have wasted a lot of time in eagle had i to do this design there. The best way to do manual routing like these i feel is to place your components in the orinetation and space you want as per your design and route it-import in photoshop and then accordingly adjust the traces with brush size being the same.(only for complicated fun boards like these ;-)

Day 39
[ Routing Time ]

Day 40 -->


    1.Tested my Shine Layer with 0.02 mm cut depth.
    2. Went through the test board scanning for possible shorts and correctinng my trace file accordingly
    3. Check list for routing-> bed leveling + more

So the order to achieve this shine layer and integrate it within your board is as follows:
1. We route the shine layer first (just in case so we know we will get it on our board without mistakes and copper coming out) @ 0.02mm cut depth
2. We then route the trace file @0.06 mm cut depth
3. Then the cut file @1.7 mm cut depth.

[Populating time]

Day 41 -->


    1.Gathered all components
    2. learnt how to stuff it and solder
    3. Learnt importance of Flux and how to add and remove solder
    4. Loved arranging the components while soldering

I liked this week as it forced me to not sit on laptop whole day designing and working but also do hands on work . I discussed with Yogesh ji my final project and how i plan to improvise it with time and use Shopbot before the given week so that i am able to figure out ideas to improve my final project.

Do notice the slight shine layer on Corbusier's bald head. Under the right lighting, this whole board glows fantastically.
