Sick-68 with Raspberry Pico


My attempt to build my own keyboard with some tasteful keycaps.


The Stuff

Tools

Consumables

Keyboard Parts

3D Printed Parts

The Make


Printing the Keyboard Case

Joining the case with Dowels and Super Glue

Connecting the Diodes

2 out of 5 Rows Complete

Connecting the columns. I found it useful to weave the wires under the diodes.

Rows and Columns are done!

Each Row and Column needs to be connected to a I/O pin


I weaved the wires to the right hand side of the board 
I also colour coded it according to this diagram by Wulfboy'

I removed the temporary masking tape and replaced it with Heat Shrink

Connecting it to the Raspberry Pi PICO

Hot Glue the Raspberry PICO to the Case
I forgot to take a picture but I put some hot glue on the I/O pins

Join the yellow and white parts together with flat head screws

The Keycaps look amazing!

The Code

Now we have to flash the Raspberry PICO with some software (older code ) newer code written by Wulfboy
  1. Download and Install CircuitPython (be sure to install the latest one)
  2. Download the remaining libraries from Libraries (circuitpython.org)
  3. After downloading the libraries, extract the zip, then copy the contents of adafruit-circuitpython-x.x-mpy-yyyymmdd/lib/adafruit_hid/ into your board at [Insert CIRCUITPYTHON directory here]/lib/adafruit_hid/.
  4. Then put the code written by Wulfboy at [Insert CIRCUITPYTHON directory here]/code.py

The Reflection

  • Tweezers were very helpful when I was trying to put all the wires together.
  • I was a total noob at soldering but my friend Jimmy taught me how to do it properly. Thank you!
  • I used a Voltmeter to test the connections of the diodes as I put things together.
  • There were over 200 tiny things to solder! I spread out the work over a few days
  • I was not in a big rush to finish the project so I took my time and enjoyed the process!
  • The switches are noisy but tasteful. It feels awesome!
  • I am really happy with the end product. Highly recommended it for anyone who want to make use of their 3D printer and practice their soldering!

Zenitsu Fanart from Demon Slayer

Image
The End Product The Journey  Inspired by Demon Slayer, I wanted to make Zenitsu literally pop out of the picture frame. So my quest begins with a fanart of Zenitsu  (By PhamVan Hoa). I printed it at Office Works. I found a cheap frame for it but it lacked anything else special. So I downloaded Blender, learned how to do basic 3D modelling. I traced out the 'thunder strikes' and 3D printed it. You can see the lightning strikes in the picture below. He has to pop out more so I decided to create more layers by cutting him out of the picture. I made thick layers with black plastic foam. (Left over from packaging) Here I decided to transfer him into a new background. I painted the background. I designed more thunder strikes on Blender and traced it with a black marker. But i feel that the picture frame was TOO SMALL. (You also get to see a bit of my hairy leg) Then I came across an IKEA product line call  SANNAHED . It is a thick picture frame with three different configuratio...

Pull Out Pantry on Wheels

Turning an awkward gap into a pull out pantry! The Awkward Gap Next to the fridge was an awkward gap. It didn't help that I left spare plastic bags, recycling and sometimes rubbish in the gap. It was just a complete heap of crap that I didn't want to deal with. Every time I walked by the pile of misery, I would think to myself: "I should do something about that". I couldn't find anything that would fit the gap as it was so awkward. So instead of keeping it clean and tidy, I decided to take the opportunity to build something useful. The research began (and ended) with YouTube At the end of this video , the roll out pantry was very wobbly. Due to the height of the shelf, the vertical part acts as a long lever relative to the bottom part. Another video  where t hey added a "cross joint" at the back of the shelf to make it more stable. It would consist of two pieces of wood or metal joined together at right angles by overlapping them in the middle. This vid...
