K501U Cyberdeck
A cyberdeck built from salvaged ASUS K501U laptop components and Orange Pi 3B SBC.
Project Status
Phase: Recovery — eMMC boot broken after Armbian SD card's u-boot overwrote bootloader sectors
- K501U salvage analysis complete
- Build design finalized (wooden case, TrackPoint keyboard, IP5389 power, HDMI switch, port layout)
- Display identified — eDP controller board ordered ($35)
- SBC: Orange Pi 3B 8GB/256GB — purchased and delivered
- SBC boot from eMMC —
verifiedBROKEN by Armbian SD card boot attempt - Display controller board — awaiting delivery (~2 weeks)
- Power system — Banggood board + cells + amp ordered Jun 3
- Bootloader repair — pending (see docs/armbian-install.md for current state)
- Case fabrication
- Full assembly and software configuration
Components
Salvaged from ASUS K501U
- Display: Innolux N156HGE-EAB (Rev. C2)
- Controller board ordered
- Hinge mechanism from K501U lid
- Need to consider details of new lid
- Cooling fans and copper heat pipe
- If I use this I'll need to design around it
Not reused:
- RAM (DDR3L soldered, incompatible with modern SBCs)
- SSD (already repurposed for other use)
- WiFi card (OPi3B has built-in WiFi+BT — no external card needed)
- Webcam (cheap as dirt, proprietary connector)
- Keyboard (huge pain to repurpose)
- Motherboard (presumably zapped in an irreparable way)
