Config for my moto harpia to turn it into a bike computer. We will need - working gps - bluetooth (ble) stuff - wayland "cage" compositor - an app - rsync service so that trails can be downloaded to a computer - ip connectivity with flight mode - give it telent and dandroid as APs - use rfkill aggressively to save battery Absent any reason I should not write the app in fennel I'm going to write the app in fennel. I want it to - display speed/cadence/time of day/power - show where I am on a map - record trail of where I've been (note: indoor counts too) ## open questions and todo itens ### can we somehow do non-flakey bluetooth (is it dbus?) ### adjust screen brightness * turn off backlight when stopped after a minute * dim the screen when following a route and the next navigation instruction is still some way off * tap to wake screen ### move widget updates from update-app-state to tick ### make saturn give visual feedback while it's loading an app How does it know when the app has finished loading? Maybe it could get told when its window is obscured ### rename Maps to soemthing that describes its role better. Cockpit? HUD? (but it's actually H Down D) Head Unit? Navigate? Dashboard? Cluster? Codriver? Satnav? Binnacle? Launch? Ride? Embark? ### show speed limit ### overlay planned route on map * fetch planned route from nominated url (don't want to type the url in, is there a better way to have it check in with a mothership?) * when off-course, calculate route to nearest point on course * show next turn * voice prompts * perhaps we need a server-side component for route planning ### save trail ### elapsed time: what should it actually show? moving time, I guess - moving time since when? ### profiles for pedal/motor differences * think about how to use nfc tags or something for profiles so that it can recognise when it's attached to bicycle or motorbike * different map features (e.g. cycle tracks) * ble power and cadence are meaningless on motorbike ### improve zoom * at coarser zoom levels, we need to query for fewer objects: either do it by hand - - houses - minor roads - major roads or so something smart but complicated like "only return ways that cover more than 1/16th the length of the tile" * autozooom accordig to speed and/or upcoming waypoints https://git.syndicate-lang.org/tonyg/squeak-phone/raw/commit/474960ddc665ed445a1f5afb0164fe39057720f9/devices/pine64-pinephone/modem-docs/80545ST10798A_LM940_QMI_Command_Reference_Guide_r3.pdf
