From the project
Rugged watercooled laptop with steampunk design
An Open Hardware RISC-V based rugged, watercooled laptop with steampunk design.
- based on the HiFive Unmatched Rev B board, because it is RISC-V - actually useable - waterproof - shock proof - long battery life - water cooled - steampunk
I wanted a RISC-V laptop. I usually carry my laptop in my car, and sometimes things happen to it. So I choose ruggedness over lightness. The laptop is my single most important object, so I looked up the parts I need, without regard to their price. Well, later I added up the prices, and got a little shock. But I have already ordered everything, so...

Dcdc3: common questions
How big is the Dcdc3 PCB?
The Dcdc3 measures 90 × 80 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Dcdc3?
75 components, from 42 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the Dcdc3 design files?
From the magwas/steam_powerplant repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the Dcdc3 design in my own project?
The repository has no license, so all rights stay with magwas. Use it as a reference, and ask the author before reusing the design.
