A Pi Zero's big advantage is it's size or lack there of. I want to give up as little space as I can get away with, and be able to connect both a network adapter and a storage device. So basically I want to keep as much as possible the size/form factor that the Pi Zero gives me. If size is so import...

Please consider a PI Zero Loaded version with the connector soldered on, soldering that connector is a pain! Then you need to learn to solder. Something like that is actually pretty simple if you know what you are doing. As others have stated, it's not cost effective for the manufacturers. It is a ...

That will probably work. It's pretty hard for me to get my Pi3 to draw more than 2A. It depends on how accurate the specs are, and how much voltage it outputs under load. Now you're probably thinking, "It's a USB charger, so it's 5 volts, duh!" But you'd be surprised how many so-called 5V chargers o...

Landal i posted the by the book answer on this. There is no wrong answer that I have posted. What there is is a confusion in that those who use the Gui version of a Linux Distro, do not realize that Samba is installed by default. A headless system without the GUI does not get Samba installed by def...

... 3. I have many friends that tell me how Linux is a good alternative to Windows or IOS. Well, I am using former for few months and I used immense quantity of time solving very basic problems that I never came across using latter. It seems that one has to be computer specialist in order to use Li...

... I found weird 50 seconds for booting. That is weird, it shouldn't take that long. They must have had a horribly slow SD card, or some kind of boot hang up (trouble connecting to a network with wait for network enabled?). Although in the video it looked like the Pi3 booted in 7.8 seconds. Also w...

The most likely cause of that failure is either a very weedy power supply or something resembling a wet piece of string rather than a cable between the power supply and your RPi (or both). Ah yes, power. Does the red LED blink while your system is in operation? If yes, then your power supply, and/o...

Works for me.

Pi3 upstairs on my desk.
Router downstairs in the study/office.

One floor and a few walls in between and it connects fine.

My conclusion... you're doing something wrong.

HawaiianPi

Right now I'm using it to reply to your thread. :D Between myself and my GF we have an original Pi-B (not +), a Zero and two Pi3s. The Pi-B was downstairs on the TV as a media device to play stuff my PS3 won't (although it's currently on my desk awaiting an OS re-load). I'm using my Pi3 on the forum...

The default "pi" user is a member of a lot more than the "sudo" group. tim@LoloPi3:~ $ groups pi pi : pi adm dialout cdrom sudo audio video plugdev games users input netdev spi i2c gpio If you want your new user to replace "pi" then it should be joined to all those groups. You might also want to add...

Often it is the micro USB power cable which causes the power problems. Too long... too thing and/or poor quality. Try a different cable. I'm afraid I got have another cable but the one I'm now, and I don't think the quality is very good. Feels cheap. So perhaps it could be it. It came with this kit...

HawaiianPi

USB specifications support 500mA from a USB port. That is below the recommended power for even the original Pi, and far below the recommended power for a Pi3 (2.5A or 2500mA). You really need to get a proper, dedicated supply for your Pi3. Powering it from the TV is just not going to work. There are...

HawaiianPi

Ah yes, that does make sense. Sometimes I forget about the little idiosyncrasies of flash memory.

Thanks.

On my Raspbian cards the FAT filesystem to starts on an 8K boundary, there's about 7.5K wasted ahead of that (and I don't care about that). I think it's because 8K is the size of the block of data in an SDCard read. It looks like your card has a non-standard layout. ... That's a direct image copy o...

HawaiianPi

Just wondering why there is 4MB of unallocated space at the beginning of the Raspbian image. Does it serve a purpose, or is it just wasted space?

As others have said, you can't have a fixed power consumption rating for something like a computer, since it varies wildly depending on what the computer is doing. For example, booted to the Raspbian command prompt, my Pi3 will vary from around 250 to 330 mA, and that's just sitting at the login pro...

HawaiianPi

That seemed like a roundabout way of doing it. Why not just create a symbolic link? cd Desktop ln -s /media/WindowsShare Or just mount the share to a folder on your desktop? If you don't want to mount it directly to your desktop, another option is folder binding. While you are creating the mount in ...

HawaiianPi

Hi and welcome to the forum. That is correct. It is not resizing to 60mB, but partitioning the SD card into 2. Windows can only usually see the first partition. Texy To expand on what texy said, the card gets split into two partitions. 1. A small "boot" partition with the FAT file system that Windo...

... Looks like ive misunderstood you, since i thought the calculations for the zero only. The keyboard probably wont draw too much power since im planning on using a wireless one. Ah, okay, I see we weren't on the same page there for a moment. I'm not sure it's even possible to get a Zero to pull 4...

HawaiianPi

Im planning to use it for programming in nano and learning how to get around the terminal so power draw isnt really going to be as high as 400ma Not for the Zero itself, certainly. But the screen will draw power. And what are you going to use to input program code, and are you going to be connectin...

Can someone put my mind at rest and tell me ill get at least 4hours from a zero, the screen, and wifi on 8aa nimh batterys? Please? Im getting worried now... My estimate for 4+hours @ 400mA was conservative (you should actually get 4.5 hours). 400mA is a lot for a Zero! I have a hard time drawing t...

HawaiianPi

Let me see if I've got this right... based on what I've learned from reading this entire thread (as well as the blogs), the Pi3 has a dynamic on-demand clock that runs at: ARM (CPU) 600 MHz normally, and doubles to 1.2 GHz under heavy loads. Core (GPU/L2) 250 MHz normally, and 450 MHz under heavy lo...

There is a specific type of cable rated for in-wall installation. I forget the terminology at the moment (it's 2AM and I'm tired), but you can't take just any old Ethernet cable and shove it in a wall. Well, technically you can, but you are not supposed to (fire/safety regulations and stuff). Also, ...
