PandaBoxComputer

UPDATE: After upgrading to a new printer, I found it possible to print the entire width of the case on my bed, allowing me to combine all the pieces of the lower liner and screen holder and reprint them almost entirely in PETG. The computer has performed well under field conditions. During a recent summer project, I ran it outside for several days in sweltering 90-degree weather and it functioned flawlessly. The outdoor photo above shows the computer on site during an archaeological excavation. Note that the legs didn't work very well, so I've cut them off and opted for a friction fit with additional hot glue instead. I'll attempt to upload the newer STL files. This is a lightweight, rugged field computer, remixed from Andrew Thaler's excellent "BeagleBox2," but based on the LattePanda SBC that runs Windows 10. This has been redesigned to utilize the LattePanda SBC (I used the 4G/64G enterprise Win version) and the 10.1-inch (1200x1920) Latte Panda monitor. The feet for the enclosure have been altered, and all input/output and control connections have been modified. My build features a power button to turn the computer on and off, a 23,000mAh battery that can be charged via an external plug, a case fan to keep the board cool, three external USB ports plus an additional expansion port inside, and two internal ports (currently holding a 128GB flash drive and wireless keyboard dongle). The LattePanda also boasts built-in Wi-Fi, eliminating the need for an external data port or Wi-Fi dongle. The system appears stable on my workshop bench, and I'm currently testing battery life while preparing an external antenna mount for my telemetry receiver. Some notes about what doesn't work with this iteration: I attempted to coat the main case pieces in Plasti-Dip, but achieved somewhat uneven results. While the texture is pleasant, I couldn't get it to coat evenly; using black would have been a better choice. The mount posts for the SBC require M3 screws, but there isn't enough clearance once the Amazon Basics 4-port USB hub is hot glued in place underneath, so I opted for spacers instead of re-printing the enclosure. I designed some feet and magnets to secure the battery access lid, but haven't installed them yet; a friction fit seems sufficient for now. I also plan to thicken the vertical walls on the enclosure to make them stronger if I decide to print this again in the future. They and the internal legs are easily damaged before assembling the computer, but probably fine once it's all glued together and tucked inside the Pelican. Battery Update: The 23,000mAh battery has powered the computer for 3.5 hours, with the screen at about 40%, while updating Windows and installing ground station software. It consumed 24% of the battery per the display on the battery, indicating over 14 hours of battery life on a single charge. However, Windows doesn't recognize this battery data, leading to an unexpected shutdown.
