I finally got around to finish building the [[Null 2]] handheld. A DIY kit using a Raspberry Pi Zero 2W. ## Soldering Soldering the Raspberry Pi to the Null 2 PCB was tough since I've had minimal exposure to it before. Definitely recommend getting a nicer soldering iron & station and good solder. ![[nulle_solder_1.jpeg]] *The Null 2 PCB with the Pi Zero and no other components* ![[null2_solder_3.jpeg]] *Soldering the PCB and Pi together* This step was really difficult and you can see how bad most of the solder joints had. I was unable to get connection on the ground pin but was able to connect a cable to the test pad to resolve the issue. In the end, I reflowed most of the connections which fixed the ground issue as well and let me remove the sketch looking wire! ![[null2_solder_4.jpeg]] *Null 2 with all the components soldered* The rest of the components were relatively straight forward to solder! ![[null2_solder_5.jpeg]] ## Building the case The acrylic case that can be made for the kit requires some special adhesive to glue together. Of course, I spilled this glue all over my counter tops but in the end, we got it done! *Though with quite a bit of glue stains* ![[null2_case_1.jpeg]] The back panel needs to be glued to the button holders. ![[null2_case_4.jpeg]] Drying over night ![[null2_case_5.jpeg]] ## Finished photos ![[null2_finished_1.jpeg]] ![[null2_finished_2.jpeg]] I ended up 3D printing a case in a clear PETG. In general, the acrylic is obviously more clear but I like the toy like design of the 3D printed one. It feels nicer in the hands and is also a bit lighter and smaller.
