Re: Raspberry Pi desktop for win or mac is it a 64-bit system??? I installed yesterday

Its NOT an RPI OS, the OS is simply Debian, the "special thing" about it is that it uses the same fast and lightweight desktop as Raspbian. the underlying OS used is x86 Debian, (x86 Intel/AMD) which exists in 32-bit and 64-bit versions, (unlike Raspbian which is currently 32-bit only) and you can i...

Re: New Pi Zero, operating system compatibility?

Has there been a plan to provide Pi Zero with armv8? Firstly, the RPF NEVER pre-announces its plans, Secondly a PI with a newer SoC (System on a Chip) is *very* unlikely, as it cannot be made for a similar price, because newer SoC's no longer use Package on Package (PoP) RAM, like the first PI's, s...

I now have my answer and would like to consider this subject closed. then simply stop posting to it. I added "[solved]" to the subject line, which is our way to "close the subject".

Re: Pi 3B+ hdmi audio output or headphone jack to VGA monitor question

Both the Analog audio from an HDMI to VGA converter (if it has built in HDMI audio decoding) AND the TRRS (A/V) port of the PI produce analog line level audio, which with a simple speaker amplifier can drive speakers, and which (without audio amplification) can directly drive earbuds.

No that is NOT possible, the camera out put is digital (serial), and Cannot be directly used to input analog video.

The sd-car was probably corrupted, and you have to re-image it with etcher.

and yes, you don't need a PI to DIM a LED especially as its an analog function.

Re: strange uart behavior

The raspberry PI GPIO's are NOT 5V TOLERANT! applying more than 4V to any GPIO pin may damage the GPIO, and the SoC, even permanently! when connecting a 5V (serial) signal to a GPIO pin you *must* use a resistor divider, or another level converter, but a resistor divider is simple, and a "top" 2K2, ...

Re: Heat damage to audio jack?

+1
its not heat damage at all, its just that the metal surface of this connector can discolour. other metal surfaces like the shells of the other connectors do not, and most contacts of connectors used in the PI are gold plated, so are immune to corrosion.

Re: Pi 3B+ hdmi audio output or headphone jack to VGA monitor question

Its easier, and with better audio quality to simply use an HDMI to VGA adapter with audio out. Using the analog audio port while NOT using compositite video requires manual configuration.
Power requirements are not an issue.

Re: ms-dos

een raspberry PI gebruikt een ARM processor geen Intel/AMD X86 processor, die moet je dus emuleren.

voor x86 emulatie probeer DOSBOX of RPIX86.

voor RPIX86 zie http://rpix86.patrickaalto.com

Re: Raspberry 3b+ : which video player with hardware acceleration

omxplayer has hardware acceleration, but its a command line program, so keyboard controlled (unless you add a GUI shell).

and KODI, which is a full media centre, not just a video player, but it is "user friendly".

Re: raspi as a... intercom?

As intercom, (with analog audio) note that a PI has no analog audio inputs, so you need an USB sound card, or an I2S audio codec to get analog audio into the PI.

Re: Powering from IDE

Yes, using the micro-USB port as power input is preferably to using the GPIO pins in any case, as you are not bypassing the polyfuse. do be extremely careful not to reverse the polarity of the input power, so use a multimeter to test if the negative input wire is connected to GND, note that all meta...

Re: Does the RasPi camera need heating/cooling for outside

One reason why the camera enclosure might want a heat source, is to keep condensation out, which could inhibit the camera's vision.

Your PI probably is NOT dead, no amount of processing power for however long will "fry" a PI, if it gets too hot it will simply work slower to stay cool, it will not damage itself. what is far more probable is that you managed to scramble the contents of your SD-card. you MUST cleanly shut down your...

Re: Gpio motors

NO!

Its not safe to connect any motor or in fact any inductor to a GPIO pin!

please use a driver IC, or at the very least a transistor (with base resistor) and a back-emf diode across the motor.
