I’ve made some progress on the Raspberry Pi based traveling mascot for the makerspace. I’ve figured out how to connect the GPS unit, and configure the software on the Pi to read the data. The makerspace’s metal roof well insulates the inside of the building from the GPS frequencies, so the device doesn’t receive location data in the electronics lab. The wooden roof of my home is much more transparent to these frequencies, so I’ve tested the GPS at home. I’ve got the C libraries loaded, and started a program to check and record the current location of the mascot.
Unfortunately I’ve run into a few setbacks. For some reason it keeps corrupting its file system, and failing to boot. A few times it’s happened has been when I made a configuration change and then rebooted. So I blamed myself. But today the Pi wouldn’t boot. The last time I used it I properly shut it down before tucking it in its box and putting it away. I had the Pi configured to register itself on the network so I could work with it remotely. It wouldn’t come online. So I grabbed the monitor and keyboard to figure out what’s going on. The monitor showed the Pi would start booting, but pause with a “PANIC: No init found.” message. A bit of web searching found that other people have had similar problems and fixed it by using different keyboards and different SD cards. Trying a boot without the keyboard and mouse plugged in gave the same panic message. So I think I need to try another SD card.
