As writing new firmware is beyond many of us, I thought it might be useful if we threw down some of the firmware ideas we'd like to see most in the new labs section. I'm sure there are many custom firmware's out there already in use which could prove incredibly useful to the wider community. I think the one I see crop up most frequently in the support pages (including from myself) would be one that tracks sunrise/sunset (depending on location), so that optimal recording parameters can be set for diurnal/nocturnal activity. Particular to this I think is being able to run different sample rates during the day and night as this would be much more battery/storage efficient for long deployments. Further to this would be the ability for more intense recording during different periods of the day (e.g. dawn/dusk). Any other ideas?
