README
README.mdhouse of wires
my fifth project for fallout!
what is it?
- the house of wires is a project to help remove the mess of wires! having a hub that usbs connect to creating a more organized layout
- the project is made to resemble a model house in which wires are connected and the project handles the rest (power etc.)
- the available usb options: 1 usb c power output, 3 usb a outputs (e.g. for charging your phone, charging your watch and anything else that needs charging)
- and then there is one usb input which spilts off into the other usb ports.
how to use it?
- print off the case and pcb (and purchase all items from the BOM)
- then to put the case on put the top half the case on the pcb (you know its the top if it has a door) and the base on the bottom, then using the 4M screws screw through. the parts of the screws pointing out the back act as the base of the project!.
- then simply plug in a usb c port into the project (at the top)
- then connect the other usbs u need!
- just use these usbs as normal!
how it works
- the brain of this project is the SL2.1S, which splits the input usb into 5 channels!
- i didnt write any additional firmware for this project, that was all that was needed!
how i made the project
- made using kicad (for the pcb) and fusion (for the CAD design)
- using the fallout tutorial (as shown below) as a guide.
my inspiration for the project/the why
- i find that my desk is always messy with various wires, and i thought it would be cool to have a way to organise these (and do it in a fun way aswell!)
- i saw that there was a tutorial for a usb hub on fallout, so i decided to give it a go (helping to improve my hardware skills!)

Questions
How big is the Usbhub PCB?
It measures 70 × 53.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Usbhub use?
16 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Usbhub KiCad files?
From the robertshepherdcpp/usbhub repository on GitHub, at the commit this page was made from: the board is PCB/usbhub.kicad_pcb and its schematic PCB/usbhub.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Usbhub design in my own project?
Its repository states no licence, so its author keeps all rights: ask robertshepherdcpp before reusing the design.
