Climate CAR Clock
Hanging the Car Cock
Do not hang the car clock by the top or bottom plywood plank. Any anchor hardware should be affixed to the side panels.
Connect Ethernet for Drift Correction and API Updates:
While the climate clock is powered off a small coin cell battery powers a clock that allows the computer to still keep track of time without external power. However, drift will still occur and increase the longer the clock is powered off. If there is an unacceptable amount of drift it is possible to connect the ethernet port on the Raspberry Pi to a router or modem with internet access. This will update the time, and thus correct and drift, as well as download any updates that may have been posted to the API including those to the "News Feed of Hope" – the most regularly updated lifeline.
General Use:
Use of the Climate Car-Clock follows the same principles as the standard portable clock.
See instructions for Getting Started, including the controls, and Update Your Clock for how to update the SD card with the special Car Clock "disk image."
The main difference is obviously size and how the screens are powered.
ON/OFF: Plug the power cable in and the car clock should just turn on! Unplug the power cable and it will most certainly turn off. 🤓
Otherwise, you can control the display–up/down for brightness and left/right for switching lifelines–using the d-pad on the controller:
D-pad or "directional pad" on the gamepad controller.
Internals:
The following should really only be relevant for debugging or reinstalling the car clock on a car.
The car clock is powered via 13 USB type A plugs that expect 5v dc power (as is standard for USB). One of these powers the Raspberry Pi computer, the brain of the clock, the remaining 12 power the 24 LED modules. Each USB draws around .8 amps and the one for the Raspberry Pi draws about .3 amps.
Data will still be transmitted through the LED panels on the top
