Lichee Pi 4A / LM4A
Compact TH1520 compute with unusually useful public hardware documentation.
3DVR Compute
Early design · building in publicA computer you can keep.
Open personal computing hardware designed to be repaired, upgraded, understood, and improved by the people who use it.
Keep the screen, keyboard, battery, and case.
Swap only the parts that actually need to change.
ModularUpgrade parts, not the whole machine.
RepairableStandard tools and replaceable parts.
Linux-firstUpstream-friendly software over vendor lock-in.
Open by defaultDocument every layer we can.
Public roadmap
The direction stays visible.
We may not know every processor, enclosure, or release date yet. We can still be clear about where Open Personal Computing is going: use the best repairable hardware available now, build an owner-controlled software and hardware layer next, and open more of the stack over time.
NowRepairable reference hardware, Linux, Portal, 3DVR OS.
NextModular devices, documented interfaces, user-owned intelligence.
LaterOpen RISC-V compute, reproducible boards, deeper supply-chain control.
Long-termA personal computing commons people can understand, repair, fork, and keep.
First device
3DVR Laptop
The laptop should outlive the compute board inside it. We are separating long-lived parts—display, keyboard, battery, storage, ports, and enclosure—from the faster-moving processor generation.
ShellDisplay, keyboard, case, battery.
ComputeReplaceable CPU and memory module.
I/ODocumented ports and expansion.
LinuxOpen software on top.
Open silicon path
3DVR RISC-V
A small FPGA-first SoC project: open CPU, memory and interconnect, a simple accelerator path for tinygrad, and Linux from the beginning. The goal is a computer stack we can understand end-to-end.
RISC-VStart with a small open CPU core.
FPGAProve the SoC before custom silicon.
tinygradBuild toward open acceleration.
LaptopFeed the compute module over time.
Prototype with what exists
Real boards first.
We can prove the laptop architecture now, then improve the compute module as open hardware gets better.
StarFive + Beagle
Alternative open-friendly RISC-V paths keep the design from depending on one board vendor.
x86 compute modules
Useful for validating power, display, thermals, enclosure, and input while RISC-V matures.
Open mobility
3DVR Open Vehicle
Extend the same repairable, owner-controlled philosophy beyond the laptop: open diagnostics, modular compute, documented hardware, local-first software, and a path from safe retrofits toward a genuinely open vehicle platform.
CockpitLinux, sensors, local data, read-only diagnostics.
LabSimulation, bus replay, bench rigs, test fixtures.
PlatformOpen hardware, service docs, modular EV systems.
ComputeOwner-controlled vehicle software and open silicon over time.
Open supply chain
Open source should reach the physical world.
Trace components and materials, document closed dependencies, find substitutes, reuse what already exists, and build local capability over time.
Community hardware
Help make it real.
Hardware, Linux, CAD, repair, manufacturing, sourcing, documentation—there is useful work at every layer.
