Re: 1TB microSD Card is real!

If you have such a large video collection, its more efficient/cheap to spread it over *several* SD-cards.

Or you could use a simple potato peeler knife, and rub it like the edge of the PCB. :mrgreen: This isn't rocket science.

Re: Best manners with the breadboarding ??

GPIO's output 3V3 (3.3V) (or 0V) NOT 5V (GPIO's are NOT 5V tolerant). if you output (ether a 1 or a 0) to an unconnected GPIO simply nothing will happen. If you do not read out a GPIO input, (or have interrupts enabled on the GPIO) the state of the input is unimportant. Otherwise I would turn on a s...

Actually, according to the MagPi, there is a way to run Android on the Pi. https://www.raspberrypi.org/magpi/android-raspberry-pi/ Not only is that a commercial implementation, that is you have to pay for it (some $70 I believe) but also it lacks hardware acceleration, and therefore is very slow.

Ein GPIO kan die ström nicht liefern.

Ein GPIO dient zum schalten, nich um etwas mit Nahrung zu versorgen.

schalt damit ein kleines transistor, (BC547, 2N2222, 2N3905) oder FET 2N7000 ein und aus.

As the bedrock edition is available on Android you'll just need to wait for someone to get Android running properly on the Pi 4 I would assume.

If you are talking about the thin fiberglass thread that comes loose of the board edge at 01:05 then no, that has no consequence to how the PI will work.

Re: Raspberry and electricity

IMHO a UPS for a PI should detect a power fail, and provide just long enough power to the PI that it can do a controlled shutdown. So it should have a mechanism, so that it can initiate such a shutdown on the RPI.

Re: Connecting an amplifier to Raspberry Pi GPIO's

If you do this you will blow up your PI, as you apply both positive and negative voltages to the GPIO, and these voltages might be significantly greater than a GPIO input can withstand. Both negative voltages, and positive voltages greater than 4V, will damage a GPIO. Question is, does the speaker h...
