  • PCB milling
  • Programming

    • In this week I learned lots of things such as soldering,PCB milling electronics and specially more steps of troble shooting.I did lots of study of electronics .Still I am facing problems during promming.So,lets see how to solve these problems.I used lots of new things during this assignment such as multimeter,solder gun,flux,soldering wire,modella machine.


    PCB Milling

    "Printed circuit board" this is new thing for me becouse I am mechanical engineer.But it is very interesting I did this stuff first time .Actually first time I was confusing about PCB and electronic components.I was learning electronics from basic.

    According to wikipedia =

    Then I found actual beauty in this subject.I did first time soldering and milling too.

    During understanding electronics and its components

    So, lets move to the PCB design... Firstly I read all information about this assignment and then decide to print Ali ISP

    From that I was downloding PNG image.,and that file I call into the modela machine.Fistly I adjest machine to the home position and then I mount 1/64 tool for milling.

    I adjest tool to the workbench by gravity.Then I adjest x min and y min.Then I create camm path for that image.

    Then

    I move towords the soldering part..I did soldering first time.Firstly I observe all soldering procedure from my instructor.Then I was trying to solder on zero board. After getting sufficient confidence I was moving on SMD i.e,Ali ISP board.

    After soldering I used multi meter,it obevious first time .I check all connectivity inside the components.

    After doing all stuff I found that my ATtiny 44 wrongly mounted on ISP.Then I was trying to remove soldering using copper resin then one track of ISP was removed then I decided that move to the brian ISP

    Then I download png image and sent it to modela machine .Following previous steps I milled PCB.

    After milling brain PCB looks like this

    After that I was mounting all components on the ISP with proper way.During soldering I refered all documents which is provided by fab assessment.


    Programming

    Then I was leading towards the programming part.I open tutorial for the programming.I followed all the steps.But I found error during flash command. Here I wrote troubleshooting part and how I found proper solution.And finally I was programming ISP!

    First you have to update and upgrade your linux system. Then download fts_firmware_bdm_vl.zip.

    Then type "cd Desktop" and enter. After that typa "lsusb". This command excuted for desktop folders. Then type zip file name. Make unzip that folder and edit make file.

    Edit programmer name inside the make file. Then make flash. I wrote only make flash command instead of "sudo make flash". Then "sudo make fuse". After that you will found there desplay one line like multiple vendor. It indicates your ISP is successfully programmed.!

    Make fuse

    But programmer never support to the computer

    Program doesn't load on my ISP.Then I was checking all connections and connectivity inside the components.I found board is ok! Then I started from zero...I did all steps of programming. After that I found I wrote command like only "make"!! It should be write as "sudo make"..When you put any command like flash ,fuse, etc. You should write it proper way.
