OmniBench
Hardware- 3 Devlogs
- 4 Total hours
Lab Bench Power Supply with a built in usb hub for a clean desk setup.
DEVBLOG 3
Things i did and / or changed
- Finalised Hub Schematic
- changed the hub front panel from 3 hotswap slots to 2
- worked on the slots for the hotswap ports
- started moddeling the actual hotswap modules”
- added a xt60 port for battery charting.
THINGS THAT NEED DOING
- exact layout of hub ports so that pcb can be made to fit.
- finish hotswap ports and modules
- make wiring schematic for the power supply.
:)
DEVBLOG 2
Started work on the top usb hub with hotswap bays.
The hub will run on a CH334U USB controller which can control 4 downsteam usb plugs. i plan to use usb-c for the hotswap modules and they will be notched so that they plug in the correct way. i plan to hold them in with magnets or with a flap down hinge i have to check and see what option will be better. power circuitry and schematics are finished and now onto pcb design and layout.
DEVBLOG 1
The idea behind OmniBench is a lab bench power supply which will have a usb hub with hotswap interchangable ports simular to framework laptop ports.
It uses a SK120X Which is capable of 120W which is i think quite a capable power supply.
-Up to 36V at 6A
The Usb Hub Aspect will use magnetic pogo pins which will snap on and off magnetically i also plan to make modules which can add oled screens or programmers or different type of helpfull things such as sd card slots or even a dac.
I also invite people who see this project to make their own modules, this will be easy because everything will be documented and the ports will be Powered by the power supply so it will be capable of many things :)
The plan is to make it as clean as possible and relativly short so that it fits well in desk and workshop setups.
The chassis i will try to be as compabile as possible for different power supplies (the silver box type ones with fixed power outputs) so that it is as easy for the user to source parts. on the front side i am also thinking of addind fixed power rails for gnd 3.3v 5v and 12v which are helpfull when you need multiple voltages for powering a project.
