Previously I made a case design for the Pi1541 standard "hat" circuit to place over Raspberry Pi 3 devices. To see what is a Pi1541 and what it's used for you can check my previous blog entry:
This time I assembled the electronic part by myself, using a prototyping PCB, by following the instructions on this page:
Fİrst I started iwth this circuit diagram.
I made my layout in Excel to place the components onto the prototyping PCB.
I also checked the layout with physical items.
After several hours of soldering I completed the circuit (looks like some device from the "Back to the Future".
...and I tested it out by conencting to my Commodore 64.
Now it's the fun part: the case design.
As usual, I used Solidworks to design the case. I took measures of the existing circuait with calipers and then made the case design by checking the clearences. Here is the modeling timelapse:
I printed the design with my 3d printer and applied to the circuit.
All good except I fotgot the LED holes!
So I drilled the holes with screw driver.
Nearly ruining the print!
Fİnally better than nothing.
I soldered the LED extension cables.
And it's complete.
Working good as a disk driver on real C64.
See you on next project! Cheers!
