I have to power some PI zero directly from PI 3. I made a USB based network and I want to connect more Raspberry zero to a Raspberry PI 3 B + to take pictures with all of them . I successfully made the network and I started to do some experiments remotely via VNC to copy the pictures to Raspberry Pi...

My USB on raspberry Pi 3 is death, can be only 5 V or data as well ? I tortured the USB disconnected and reconnected many times some Pi zero. I want to take pictures with some Pi zero and save them on Raspberries Pi 3 where I have to do some more stuff with these pictures.The Pi zero was charged via...

I tried this many times and This still required a password.

I have been struggling for a week to do something to copy files automatically from Pi zero to Pi3. All I need is a way to use a Linux command to do this. I will call it from my Python program, no problem with that. I open a topic here: https://www.raspberrypi.org/forums/viewtopic.php?f=36&t=250682&p...

I need only some commands that work to copy the files without password automatically, of course nothing manually. I will integrate and call them from my python scripts. I already did this with other Linux commands and worked fine. Thank you for your advice you gave me so far.

I struggle to copy from a PI zero to a Pi 3 without a password for a couple of days and nothing works properly. I have to copy some pictures from PiZero to Pi3 each time when a picture is taken without typing a password. Doesn’t matter if I use the command from PI 3 or Pi zero even if the both ways ...

I tried to make a image of my SD card with a Raspbian installed and configured in a certain way to do some things. I made an image with Disk Win 32 disk imager. When I try to write the new card I had a message errors that I do not have permission to write in a partition. Well, the card I tried to wr...

It sounds good. I did not have the time to try. I will read them first. For the moment, I can connect from a Windows Machine through VNC and PUTTY with both USB connection and Wireless. I can open two windows that show the same things inside the Pi zero with the two connection, USB and Wireless. The...

I already tried some of the above but I will try the other ones. I did not use "local" or IP instead of allocated name even if I used it experimentally from Putty and VNC from the laptop (I can connect Pi zero to the laptop with the same configuration). I tried to do what I already found on internet...

I am on Pi 3 B + as a master. I can connect to a raspberry pi zero that work as a gadget slave via USB. With ‘SSH pi@pizero2” I can log in the Pi zero after typing the psw. I can use camera, do anything from terminal as if I am on Pi zero. I wrote those commands to copy the files from Pi zero to Pi ...

After many efforts I connected a Raspberry Pi zero to a Raspberry Pi 3. With the same configuration I can also connect the laptop to Raspberry zero without a Wifi or wired UTP based network. Only USB. I can SSH into Pi zero from Pi 3 and control camera, make whatever I want inside the Pi zero from P...

I understood from this movie that an USB data cable can be turned into OTG cable. So that I was thinking I have to make some changes or I need an adapter: https://www.youtube.com/watch?v=_Kv5lJKJhDg That is why I was so confused about this. That is a very good news to know that I do not need adapter...

I have a couple of Android devices, tablets and smartphones and for charging I use cables that are also for data transfer. I have also, a lot of spare cables like that. What I want to do is to connect a PI zero to a Raspberry PI 3 +. As I find on internet I need an OTG cable. As I understood these a...

I want to make a device for panoramic pictures, 360 degree with some overlapping angles to prevent discontinuity. I need 8 pi zero units to do this and a pi 3 where I want to save them and do other things like email them, etc. I already can do those with a single pi 3. I will buy the new vesion of p...

I made the worst mistake to install TightVNC to use remote desktop from my laptop that is by default installed. I didn't know that VNC is much better but when I installed it on some tablets I saw that it doesn't create another desktop but accesses directly the existing one, so I can see exactly what...

I put some more extensions and connections between one of my Raspberry and its original source. The longer the wires and the more connections, the higher the electrical resistance, then the lower voltage. Time to time I see the yellow lightning symbol on the top right corner on the screen. I have no...

I am working at a project where I need, between other things, to send SMSs and be connected to the Internet at the same time. I have a modem Huawei and I can do both things but not at the same time. It is like only ttyUSB2 can be used, even if the modem has attached two more: ttyUSB1 and ttyUSB3. Th...

I have a Display controlled by an integrated T1637 circuit. I found a python library that controls my digits. Their example was a clock and it was not hard to change it for what I needed. The display has instead of the two clock dots, decimal dots, because I needed to display comma numbers. Strangel...

It was my library on raspberry faulty. I put it on an Arduino first to make sure ir works. Then I found a better library and works on Raspberry, too. The only problem now is that I can not control the decimal dots. But I can put off that for a while.

Does somebody know if Adafruit has a branch in Europe? I opened an account on their site but I can not post new topics. I have now idea if they send their items from USA, as I found most of the components there. I live in dk and I'd like to buy some of their products, so that they are delivered fast...

Where can I find some reliable wire jumpers?All the male connector are too thin. They never gets stuck and I could not insert them properly in the female connectors.
