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.

Re: Rotary encoder on Raspberry Pi 3

If you google "rotary encoder pigpio" you'll find usage and code for joan's "pigpio" which can be used for rotary encoders. There's an example there.

Re: Where can I solder my power supply cable to Pi3 platine?

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 ...

Re: WD Pidrive - problems

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?
