    NUS EE2001 part 2

    Thought I would post of couple of picures on the project im working on in school
    I fondly refer to it as a nuclear bomb.
    Amos drilling the PCB (Printed circuit board - give it a Google if you dont know what is it)

    My first PCB, I was so glad that it worked.


    Front shot of the PCB
    Once the PCB was all soldered, it was time to break out the crimp pins
    That is a crimp pin.
    Normally people use a proper specific tool to do it, but sadly my group was unable to get the tool from the lab
    Hence, we ended up using a pair of pilers to crimp everything together.
    It was insanely hard, but we
    Can you see the extreme joy on my friends face?
    It says " Crimping is fun !"
    We really made quite a mess of the classroom we were in.
    We tried to clear it up though !!

    Right about 5 mins before this picture was taken, we realised that we were short of material.
    We had underestimated the number of pins to Crimp.
    We underestimated by almost 50%
    The final tally was about 220 - 240 pins that were crimped using a pair of pliers
    A really tiring job.


    Once all that was done, my fabrication began.
    It was time to break out the rulers, tape measures, pencil and calculator to mark out all the dimensions on the acrylic.

    Next time I post it should be on how I fabricated the bomb.
    Anyway im super sleepy now, good night !!
