Re: Rasberry pi 3 login

Yes, no problem.

Use the same process to write to the card as you did the first time. You don't need to wipe the card first.

Re: Rasberry pi 3 login

Ahh - OK. You having two threads doesn't help.

Raspbian lite is fine where you're comfortable with a command line interface and don't need a desktop GUI interface.

It sounds like you need to download and install "Raspbian Stretch with desktop" from https://www.raspberrypi.org/downloads/raspbian/

Re: Need help with a analog clock upgrade

Hopefully not off-topic for this thread (if it is I'll start another one) - but I've been looking for an analogue hand mechanism where the hands (hour/min/second) position can be set/controlled from a pi or microcontroller but have never been able to find one. Any ideas? I can't believe you can't ge...

Could the two be linked with your slowness? Is it damaged and now throttling down? Someone here can probably tell you how to find out.

Re: Raspberry Pi 3 connection to a breadboard

Or do a search for "Raspberry pi Cobbler" - that will bring up a whole range of connectors from Pi to breadboard which combine the benefits of the previous post with actually getting the connections on your breadboard.

(I just use jumper wires myself - but the cobbler boards probably make it safer!)

Re: Low Voltage Indicator

Well, either the power supply you have isn't capable of maintaining 5v at the power usage you need on the Pi and peripherals you have attached, or the cable between it and the pi isn't good enough. In my case I had a good power supply from a reputable manufacturer, and what I thought was a reasonabl...

Re: Low Voltage Indicator

It's nearly always due to too thin wires in the cable between psu and pi - low quality cables that are just about ok for trickle charging a phone just aren't good enough for delivering power to a pi.

IF the Pi does start using USB-C, I hope someone comes out with a really inexpensive microUSB to USB-C converter, because I have a *lot* of microUSB PSUs for Pis. How about 5 for 84p with free delivery ? My daughter's phone has USB3 and her cable broke. It cost me a padded envelope and 90p to send ...

Yay! On fourth or fifth startup try it booted.

Doesn't seem like a good percentage though.

If you have any idea how to get it more reliably booting I would appreciate it. Do I need to be careful with any apt-get upgrades having done the rpi-update, or should it all just work?
