Portable MIDs were a beautiful thing — an almost pocketable device running a full version of Windows that’s fully usable without a table in sight. While smartphones and tablets have, pretty much, eaten up any market for them, they remain a viable form factor for mobile computing. Those MIDs are exactly what the Pi-to-Go reminds me of. A custom build using the hacker-friendly Raspberry Pi, it turns the humble mini-computer into a functional portable rig. Sure, it’s a bit too thick for unbridled mobile comfort, but it should get the job done quite impressively. 
The Pi-to-Go sports a 3D-printed computer case, complete with custom parts pulled out from a variety of sources. The 3.5-inch LCD is a low-res (640 x 480 pixels) display pulled out from a backup camera system, with a store-bought USB mini-keyboard and touchpad combo installed for input. Additions to the stock Raspberry Pi include a laptop battery for power (Dell Latitude D600, removed from case), a powered USB hub to hook up all the peripherals (gets power from the battery), 64GB SSD, and wireless dongles (Bluetooth, WiFi) stored inside the case. It runs a stock version of Raspbian Linux, with a 10-hour battery life. 
Want to build something similar? Nathan Morgan shares step-by-step instructions on how he put it together, complete with links to where you can get each component, wiring schematics and STL files for the 3D-printed case.
Before even getting the 3D-printed case, the entire Pi-to-Go system should cost you just shy of $400, so it’s far from the cheapest computer out there. You can hit the link below to learn more.
