What is the FabISP

The FabISP is an in-system programmer for AVR microcontrollers, designed for production within a FabLab. It allows you to program the microcontrollers on other boards you make.

The Electronics Production assignment is to mill the board, stuff it with components and program it. We will be using these programmers through the semester to program the other boards we create.

• This one uses a mini Usb connector to make durable

Mill using the fab modules and a 1/32" bit.

Roland SRM-20 is the machine that we have in our lab to mill out the boards

To make files that the machine can use we have to convert the images to RML format

We can use this website to make the files.

www.fabmodules.org

Import the PNG image of the board and the website will convert it to a usable RML file.

Do this with both files

Now we can load the RML files in to the Roland control program

Then we have to sett the x/y and Z possition

When the milling is finished we can clean it and start the soldering process

Because I did not hava a good setup for making PCB I made one with materials laying around in the lab

I had a old computer laying around and took out the fan and attached it to the power supply for ventilation

Then I took a led strip and attached it to a black plexi glass i found laying around and connected it to the power supply

Vola.. Ventilation and a good light for soldering small parts.
