Life with Deep Racer - Part 1
My Deep Racer has finally arrived back in Australia
There's a few things I have learned already, and I will share them as I go along.
Charging the batteries
PowerThe charger for the compute battery pack simply needs a 3-pin appliance cable to connect it to non-US power outlets. Yes, you can use a plug adapter, but I find they get loose over time.
The LiPo charger needs a 9V 0.5A plug pack. The centre pin is positive.
There is a considerable power drain on the CPU battery even when the module is off. My advice is disconnect both batteries when not in use, because that big pack takes a long time to charge.
Tail light coloursNote that these colours might vary depending on the version of software you're running. When I first unpacked it, there were no lights at all.
Red - Something is wrong. The usual cause is failure to connect to WiFi. The official documentation lists some troubleshooting tips
Blue - Connecting to the WiFi network
Green - Ready to go. Motor battery is also connected.
wifi-creds.txtI'm not too happy about this because it does not seem to be consistent. If there is a SPACE in the SSID or password, you must use single quotes, but you can use double quotes if there are no spaces. I am not sure if this includes special characters as well.
I have observed, but I am still investigating that the wif-creds method of configuration does not appear to be happy connecting to networks with a hidden SSID. I will update these notes when I understand what is happening.
