Display Hardware - 18v battery option to be developed (pcb redesign) #42

Open ChangeD20 opened 1 month ago

ChangeD20 commented 1 month ago

Current issues:

Horn out of function when battery is below half charge

Advantages:

Reduce costs (battery and other peripheral components like cables/connectors)
18v battery's (like for drills) have much more power, step down ensures 12v supply over longer time while battery voltages decrease while in operation

New components

18v batteries
Connector for batteries
fuse and fuse holder (had been integrated in the cable before)
Step down to 12v
Additional mosfet/relay for using the horn directly with 18v
heavy duty switch

Pcb resdesign: Design decisions to be made

additional mosfet as peripheral or on pcb
Changes to the connectors to be made? (Heavy duty switch and mosfet for 18v horn on pcb or peripheral)

MOSFET decision on type / model - to be tested
