Introduction

in this week i try to use electronics printed circuit machine to use that to sketch the electronics circuit [electronics printed circuit machine by using software colled eagle it was also challenges as when we hit the ground and try to implement the design the issues that i face is because the machine that i have in fab lab Rwanda is monochrome printing one side printing on the top only.in my electronic design i have the input output device is th device that have input device and output device in that assignment the input are the push button that send information to the microcontroller to turn on the led .

design in eagle

EAGLE (Easily Applicable Graphical Layout Editor ) . It is available for Windows, Mac and Linux and you

The step that are using to design the circuit in board.

i have the first it Design the circuit in schematics the characterized by suitch button and led.

the second is to convert the schematics into the board.

convert design of circuit that are design in board into the png Next step is to arrange the components on the board. For that there is an option "Switch to board". Click on that. Here we have to arrange the components as wee need to be in the PCB. After arranging, click on the Auto route option to route it. I forgot to take the scree shot od that. But i have the exprted monochrom png image I used to mill. See it here: .

and to create the PCB outline.

I have converted my images from .png to .rml since its what the milling machine takes as input. I used fabmodules to convert input circuit images to rml. On Input format drop down I choosed image(.png), on output format I choosed Roland mill(.rml), and on process I choosed PCB traces(1/64). And continued selecting on machine I choosed SRM-20, other settings were made automatically then I clicked on Calculate button for converting it. .

that schematics show some configuration by using fab modules.

After calculation done on the image, the rml file is generated .

Now I have done the same thing on the edge cut file with some modification like on process I selected PCB outline(1/32) and on cut depth (mm): I entered 1.6 cause I want to cut through the board.

After calculating the path for the tool the RML file is generated.

that are tools using to design the circuit in board.

we use the software called v panel to set the machine.

Now that I have fixed the board on the bed, I am ready to setup the machine and start milling.

I soldered the components
