Week of 2/28

This week I worked on creating a bracket for my raspberry pi to mount to my projector. Most of the parts can be 3d printed or laser cut easily but I am still figuring out the best way to make certain parts of it, because I cant 3d print some of the parts I modeled. I'm probably just going to split the part into more printable parts to assemble or just remake it in a way that it can easily be made. The bracket is also including a custom case with a fan mount for my raspberry pi. I have an old case which I'm going to use to get the dimensions of the mount and reference for ventilation. Originally I thought it would be easier to use an online chart of all of the measurements of the raspberry pi, but after making the bracket around those values I checked my own with calipers and the numbers were slightly different so I went back and changed the incorrect numbers. I'm also going to bring my projector in so that I can accurately model that as well.

This is the diagram I first used when modeling the bracket.

The most recent update on the typewriter circuit board

Later in the week I continued working on the typewriter circuit board. I now have all of the logic gates, diodes resistors, micro controller soldered onto the board. I had accidentally soldered the wrong capacitors onto the board and when removing them I accidentally got parts of the metal stuck in the pad which took a long time to fully remove and clean but I managed to replace the 2 incorrect capacitors. I now just need to solder a connector and one more resistor, and it will be complete. This should be finished by the end of the day.
