If it's not actually Raspbian Lite then the problem could be that on the VNC SERVER you need to go in Options -> Expert -> CaptureMethod = 1 See Black or blank screen when connecting to VNC Server running on Windows 10

Based on the answer by Ingo, I went and made a script to do this job. https://github.com/Autodrop3d/raspiApWlanScripts The gist is that there's one script to run that'll setup the Pi for reboot-less AP/STA switching and then there are helper scripts that'll actually do the switching for you.

According to raspi.tv, the idle current is 120mA. Sizing the battery for 10 years: That would be an enormous battery. Based on this tomsguide.com article, a Moto G7 Power has a 5 AH battery, so you'd need the equivalent of 2,104 Moto G7 Power batteries to provide that much power. That's not even accounting for any other power loss the battery may suffer, ...

The pi zero is horribly slow. I am using one as an access point now(without internet) and it can barely run ssh besides it. if you really want to do this use a pi 3. in addition the pi 3 has an ethernet port and some models even have POE with add on and built in wifi. i cant imagine that the speeds will be any better than what you have now though i do not ...

So, after digging some more and finding this article: https://forum.arduino.cc/index.php?topic=477085.0, it looks like the issue has to deal with interference somewhat. I decided to just run the third one on spi0 and things are working the way I want them to.

From the kernel dump cannot be said very much about the cause of the kernel oops. So you have to narrow down the possible reason. If you have stable software running then it is mostly a hardware defect. First you should look at the The Boot Problems Sticky and follow it. Then I would try to run the RasPi with an unmodified image Raspbian Stretch Lite. If ...

Problems are often occuring when using both bluetooth and wifi at the same time with both rpi 3 and zero. In order to solve problem concerning the bluetooth (used for me to share audio content), I've found two solutions : disabling wifi when bluetooth is used (which can disconnect you from the pi if you use ssh) using a specific bluetooth adapter instead ...

The right combination to exit nano is Ctrl+X. If you accidentally killed apt upgrade (or it crashed on its own), try re-starting it right away. Deal with any error messages before you reboot, otherwise you may end up in the same state again. If you lost USB, you still have an option to login using a USB-to-UART dongle connected to UART pins. You will need to ...

Question RpiZW send PWM signal of 800Hz to control sampling frequency. About every second something happening, messes up data logging. With different sampling frequencies (200-800Hz) same thing happened. Remove sensor out of the circuit, Rpi PWM pin straight to a pin, detects data ready Still about every second I miss some PWM signals. Why? ...

Here is a cheap USB hub with Ethernet adapter that I have used with Pi zero W: https://www.ebay.com/p/White-Micro-USB-to-Network-LAN-Ethernet-RJ45-Hub-Adapter-with-3-Port-USB-2-0/2137368637

Question Rpi Zero W has no usb port. How to make serial communication? Answer But you can use the UART TxD (GPIO 14) and RxD (GPIO 15) pins on the 40 GPIO connector to do serial communication. By the way, I also use Rpi PWM to control [servo] motor. I found its PWM signal rather stable. You might find more details in references below. References ...

You can use systemd-networkd to configure your access point as you like without installing and/or configuring additional helpers. Just configure the default Raspbian Stretch installation and you will get what you want. You can use an uplink with Network Address Translation (NAT) or a routed uplink. Very nice is a bridge that will direct expand your subnet ...

The tutorial for the WiFi repeater uses systemd-networkd. The second tutorial from adafruit to install the tor proxy doesn't respect sytemd-networkd and does it's own setup of the needed iptables rules. I think it's possible to combine this but it seems not to be an easy task. A better way in this combination is to use also systemd to extend the tor.service ...

I have written you a tutorial below on how you can setup your pi as a router. although performance will likely be abysmal(sub 20mbps) because of the amount of encryption required to operate an accesss point and the pi's lack of hardware acceleration for this particular software. id recommend you start by bringing your os up to date by running the following ...

I would use one or more UBECs (Universal Battery Eliminating Circuit). Use more than one if needed to supply the total current or different voltages. A UBEC converts a voltage in the range 6-27V (depending on its specs) to 5V or 6V (depending on its specs). They are fairly inexpensive and are widely used for your sort of application. https://en.wikipedia....

Question WittyPi2 on Pi Zero W Raspbian Stretch - I2C read / write fail The Pi can do one round of shutdown/start-up, but after this point the I2C errors begin. However, this works absolutely fine on my 3B. Answer Well, if WittyPi2 works well with Rpi3B but not RpiZero stretch, then the problem is with RpiZero. The WittyPi2 user guide ...

On the Pi Zero and Pi Zero W the 5V pins are directly connected to the 5V input from the µUSB connector, as can be seen in the schematics Other models have additional components (polyfuse, ideal diode etc).

Not entirely. There are two Q&A you should read: 1, 2. The first Answer tells us that the voltage output from the USB supply is regulated iaw the USB standards, and therefore needs no further regulation on the RPi. So, I'd say the answer to your question is, "the 5V pads are regulated iaw the USB specifications and standards". The second Answer is ...

Question Would that be appropriate to power the Raspberry Pi Zero W directly from a 12 volt car battery? Answer Well, all these years I have been using a "12VDC source" to INDIRECTLY power the Rpi. I emphasize the word "INDIRECTLY", because of course I do not directly feed 12V to Rpi. I use a fixed or adjustable step down regulator to convert 12VDC to ...
