Re: SSH user name and password

If you are trying to get in as Root. You need to go into /etc/ssh/sshd.config and chane the last part of "PermitRootLogin" to "Yes". Which is an exceedingly bad idea. You should only permit root login with a public/private key pair. Yup, a very bad idea. There is no need to ever use the root accoun...

Re: UHS-3 Micro SD Card. Can the Pi take advantage of the sp

UHS-I and UHS-II refer to bus types, while U1 and U3 are speed ratings. Does the Pi support 1.8V SD operation required to take advantage of a UHS-I card?

Re: SSH "Access Denied"

It's also simpler to SSH by name, rather than IP, since most personal networks use DHCP. The default name for the Pi is "raspberrypi" on the network (provided you haven't changed it). So... ssh pi@raspberrypi Should get you there. Obviously if you have more than one Pi, you should rename at least on...

Re: Raspberry Pi Zero no display

What are you using for a power supply?

And have you tried:

hdmi_force_hotplug=1
hdmi_safe=1
config_hdmi_boost=4

in your config.txt?

And can you SSH into the Zero after booting?

Oh, and have you tried a different mini-HDMI adapter or cable?

Re: First project - Ghetto watch (need professional review)

Something like that would probably be easier with a micro-controller, and maybe a piezo instead of a motor. The Zero seems like overkill, but if you really want to do it with a Zero, consider the piezoelectric element as an alternative to the motor. It will require less power and should be effective...

Re: Duplicate Micro SD Card

Can you use the new feature in Raspbian to copy the card? That's what I would recommend as well. It does require a USB card reader for the second SD card, but it works really well, and takes less time because it only copies data blocks and skips the empty space. It also handles different sized card...
