Rahmanshaber remembers the pocket computer systems of the early 2000s, however then smartphones took over, smoothing out the sides with glass screens and swipes. Now, with elements just like the Raspberry Pi broadly accessible, anybody can deliver that period again within the type of the MutantC v5.1—a handheld PC you assemble your self, piece by piece, till it looks like an extension of your grip.
Begin with the guts of the construct: a Raspberry Pi Compute Module 4, tucked right into a customized provider board that spreads out its connections like a map of prospects. Select your reminiscence—1GB for mild duties, as much as 8GB in the event you plan to multitask by spreadsheets or stream movies. Storage comes by way of eMMC for pace or an SD card for simple swaps, and WiFi retains you on-line with out additional dongles. The entire setup attracts energy from two batteries in sequence: 18650 cells for a 7000mAh pack that lasts by a morning of labor, or beefier 21700s pushing 10000mAh for all-day adventures. Slip within the batteries and the MutantC powers to life, able to boot into Raspberry Pi OS or no matter Linux taste you like.
Slide open the 5-inch LCD—although a 4.3-inch possibility works if you would like one thing extra compact—and the display screen glides up on rails you print your self. Beneath waits a 61-key keyboard, every button customizable for shortcuts or layouts that match your typing rhythm. Six shoulder buttons sit alongside the sides, excellent for fast navigation in menus or firing off instructions in video games. For pointing and clicking a 3D Corridor-effect joystick takes heart stage; magnets sense its tilt with out put on so actions keep exact over years of use. Two additional buttons close by deal with left and proper clicks, turning the entire high right into a makeshift mouse pad you management along with your thumb.
An ESP32-S2 chip handles the inputs, translating key presses and joystick actions into alerts the Pi understands. A strip of NeoPixels glows alongside one aspect, related on to the Pi for alerts: a delicate pulse for notifications, a gentle mild when the battery will get low. Every little thing suits inside a 3D printed shell, sufficiently big to slot in a bag however thick sufficient to sit down on a desk. Print the elements from the information Rahmanshaber shares without cost, sand the sides for consolation and screw it along with screws that double as handgrips.
Growth turns the MutantC right into a chameleon. A PCIe Gen2 slot is prepared for add-on playing cards – an SSD for sooner file entry or an OCuLink adapter to hook up exterior graphics if you wish to render extra. Two USB 2.0 ports flank it, for thumb drives or peripherals, whereas 17 GPIO pins expose SPI, I2C and PWM traces for sensors or customized circuits. An exterior show port mirrors the display screen to a monitor, so you possibly can dock the hand-held and work massive if you’re dwelling. Rahmanshaber designed these openings with future upgrades in thoughts; plug in a GPS module from an earlier MutantC model and abruptly you’ve gotten a transportable navigator.
Meeting requires no magic, simply persistence and primary instruments. Obtain the invoice of supplies from the challenge’s GitLab web page the place each resistor and wire is listed with sources. Solder the board in a day, following the steps on Instructables with images of every connection. Flash the firmware to the ESP32 with a easy add – no deep coding required – and check the keyboard by typing a line right into a terminal.
