This is what happens when you actually make an ultra-compact computer of the size of one Lego block
A typical computer is large and heavy. However, Mr.
Brick Assembly-YouTube
Ancient first pulled out one of the RP2040s that are also used in the Raspberry Pi Pico .
The Raspberry Pi Pico die needs to be sanded and cleaned because the copper does not go all the way to the edge of the board.
The finished die looks like this.
Use the pedestal made with a 3D printer to fix the rest of the Raspberry Pi Pico board.
Apply flux to the board ......
Solder and fix the boards together.
Remove it from the pedestal and re-solder it for a clean finish.
Solder a thin wire to attach the accelerometer.
This is what the board looks like after soldering.
Use another pedestal to mount the display.
Fix the display and the board with adhesive.
After inserting the micro USB cable and performing an operation test, the image was output to the display safely.
Next, we will make a finished computer case. First, apply petroleum jelly to the mold to prevent resin from entering the USB port.
Add paint to resin and mix.
Put the resin mixed with the paint into the
Pour the resin into the mold ......
The created computer is also carefully put into the resin.
When the resin hardens and you take it out, it looks like this. Excess resin hardens on the underside of the case.
Use an electric file to scrape off excess resin.
When the completed computer was fixed to the Lego block, the image was output to the display.
When you touch the round part at the top of the computer with your finger, the image on the display changes.
Mr. Ancient has published the code of the computer created this time on GitHub.
