Week 7 - Electronics Design - Part 1 - hand made?



Redraw the Echo hello-world Board

Fab Resources

These are the example files for the board, it is required to add at least an LED and a button.


Drawing Parts

I used the physical parts as a guide to draw out the circuit


Drawing Scan

I then scanned the drawing for conversion using Illustrator into pngs for fabmodules


Adding Background Pads

I started by adding specific sized rectangles to the places they were going to be needed (disregarding the fact that most pads are sized for the specific part)


T1

the parts in place


Traces Width Pad

Measuring the pads


Traces Width Lead

Measuring the traces


Image Compilation

I created a top down collage of the parts to make drawing the circuit 'easier'


Overlays

I tried overlaying what I had created thus far to not much avail


Traces VCC GND

And I just continued down this broken route for far too long


Traces

Like way too long


Traces Example

But I did end up with a png file I could try in fabmodules (which failed spectacularly because I hadn't considered anything about it really)


In conclusion - use the software people spent a very long time building, it's easier and less problem and disaster ridden. (This is although something I want to come back to for my final project I think)



I decided to abandon this 'version' of the board, as I was expecting to run into many milling errors or other related issues throught the manufacturing process.

I therefore decided to redraw the board in illustrator using the example board as a background to work on.


I also made a camera remote this week

Remote

One of the buttons triggers the focus ring, the second butter in conjunction with the first button triggers the shutter.

This configuration of the button legs didn't fuction as required, I rearranged the legs and pins, such that there is now a focus button and a shutter release button, which are independent.


The first button shorts the focus line to ground, the shutter button shorts both the focus line and shutter line to ground.
