Yeah, every phone has radio
WHAT THE FUCK?!
@m4iler the N900 is just the best
@m4iler @martijnbraam Raspberry Pi with a wire on some of the pins can transmit radio using.. searching web.. ah abusing the clock. https://hackaday.com/2012/12/10/transmit-fm-using-raspberry-pi-and-no-additional-hardware/
@jasper @martijnbraam @m4iler It's the wire attached to the RPi GPIO pin that I'm concerned about. In the us on the FM broadcast band it's 150 microvolts per meter at 3 meters unless you comply with some other requirements as well (bandwidth, limited transmit time, etc). That's for all of the radiated power, not just the part that's within the band or within the receiver's bandwidth. That's receivable at 3 meters if it's narrowband. Might not be if it's not filtered at all.
@m4iler @martijnbraam @jasper The hackaday article is talking about a range of 100m from a wire hanging off a GPIO pin. While that's achievable with a legal part 15 FM transmitter, it's almost certainly exceeding allowable field strength when transmitting using a square wave, because the allowable field strength is 100 microvolts/meter lower and much of the signal is outside the receiver's bandwidth.
@martijnbraam Are there any kernel devs working on PMOS that you or Ollie know of?
@trash that depends on how you measure kernel-devness, we have a bunch of people submitting kernel patches for mainlining devices. A lot of the big kernel stuff is using kernel work from projects that were already running for mainlining some popular devices, like the n900 and some Nexus devices.
@martijnbraam Anyone who submits patches that eventually get integrated into the kernel successfully.
@martijnbraam Suddenly I feel so bad for throwing mine away, although it was in a moment of clarity after replacing the USB connector for the bazillionth time... Kudos!
@raccoon That's why I use an external charger, I barely need the usb connector so it doesn't get damaged so easily.
