Horrible mistakes – Wrong parts order

This week I finished the board design for the muscle sensor, after trying several layouts.

( old ones )


Here’s the fake final look.

And I use OtherMill to mill the board, because the Roland can’t do the curvy routes.

And here’s the result whoo!


And then when I was happily ready to solder the parts on, I found out that what I ordered for the 150K, and 80.6K resistors were way too small!! Their type are 0402 instead of 0603! What was I thinking?! So tiny omg *_*


After being down for a while, I ordered parts from DigiKey again and refueled my life with hope.

And, I also found out that I have surface mount 1N1418 diodes when I was examining my parts ( so many mistakes ooops ), so I changed the schematics again! Replacing the through hole diodes with the surface mount ones, creating curvy dimension, and a making a hole for hanging, possibly.


WTF Moment_01

Last night I found out that the idea that “Wearing mask = isolating yourself” is totally wrong. If I really want to isolate myself, I can just escape and hide myself in an empty room. On the moment that I put on the mask, I choose to stay in the environment and deal with it. Wearing mask is not isolating myself. It’s a way to interact with others relaxedly.


I spent so much time on thinking about examples based on the “mask = isolate” rule, which is wrong.


Oh well. At least I figured it out. Yay.
