6. Electronics design

Didn’t expect it to be a hard week , yet it happened to be .

And the illusion started with a quite understandable Group Assignment

Design

First I started exploring KiCad , quite similar to Eagle.

I downloaded the libraries from this Link While following the instructions in the Read me file .

Watched this Tutorial then started working

Got the components from the Fab library I downloaded .

Connected all together .

Then started working on the Schematic which took so long to place all wires correctly .

I didn’t want to cheat from an old design and decided to figure it all out by myself . Silly me !

After like two hours of trying , I ended up add 2 0 Resistors to bridge some wires .

We can sum our KiCad first experience as happy , Software is easy to use and the steps were simple to me ,

just add components , connect with wires , Annotate , generate netlist and move to Layout where we arrange , draw routes and outline And plot to get gerber files .

Milling

Prepared my files , first using Gerber viewer

Then edited the images using Gimp

Finally the G-code using Fab modules .

And off to milling

Soldering

It was a walk in the park .

Programming

Using the FapISP programmer made on Week 4

And afer removing the 0 Resistance , As it prevents the programmer form being programmed again , I prgrammed my board .

I downlaoded the Hello.eco make file , open the CMD and start commanding

cd Desktop/code Getting to the directory where I saved the code .

make clean

make hex compiling code

make fuse set fuse to use external clock

make program Flashed the code and board is now programmed

In Arduino IDE , opened serial monitor and started typing and the board seemed responding.
