Rack Design
Posted in Tech update
This is a first version of the rack design with Ethernet switch.
(Off topic : Because of the Covid lockdown in France, I have to build the rack with materials I already have in my workshop…)
The design is for 7x phone slot cards. Each slot card has a -kind of- standard frame to accomodate any phone.
The slot card hosts the DC/DC to power the phone and the Ethernet adapter.
On the back of the rack there’s a PCB to provide power to each slot.
For this first version, the power supply is not embedded yet, but it should not be an issue, considering how low the required current is to run the phones (RedMi Note 7 needs from 1.5 to 4 Watts at this point).
Next step is to 3D print everything and assemble all this stuff !
