Re: Chromium crashes when I go to Pandora login page

I have found the problem with my crash, Chromium was updated and reset the options, and the hardware acceleration option was changed. It's working OK now

Re: Chromium crashes when I go to Pandora login page

It would probably help those looking into issues if you could say what crashes, when doing what and where, ideally how to replicate that. Yes, you are right, sorry.

Magpi 51

As I have a string of LEDs that I am playing with, using some code I cobbled together myself using Python, I thought I would try out the Christmas lights as a bit of fun as shown in the Christmas edition of MagPi. I tried out all of the various codes but unfortunately I could not get them to work. I...

Model 3 Slow

I have at least one of every Raspberry-Pi model, and I noticed that each one is a bit faster than the previous one. However I find that the Model-3 appears to be slower to react than the model-2. I set both the model 2 and the model 3 up with the latest OS (Pixel) and running them side by side the r...

Re: Ultrasonic sensor on raspberry pi zero

The Zero is powered with 5 Volts and the echo signal is passed thought a voltage divider to give 3.3 volts to the appropriate pin on the Pi. Although it does look like the voltage may be low somewhere.

Ultrasonic sensor on raspberry pi zero

I have been trying an ultrasonic sensor, HC-SR04, on various versions of the Pi. With any of the large board Pi's the sensor gives me a maximum range of about 100cm, however, when using a Pi Zero it only gives me a max range of about 50cm. I recently got the latest version of the Pi Zero, and have t...

Re: Power supply for multiple RPi units

Works very well, but it takes up some room on my work bench. One day I will try to fit into a smaller space like a black b...

Re: Pi 2 power question

Hi I just got a Pi2 and my first experience was not so good. It turned out that the old power problem is back with Pi2. You really need a good PSU as it consumes more current. I have a number of 5VDC phone type chargers that do not work with the Pi2, so I used a home made PSU that worked very well. ...

Be careful with the voltage, the maximum voltage for the controller is quoted at 18 Volts DC and they mean 18 volts, as I found out much to my chagrin.
