Re: SanDisk Extreme 128 GB SDXC Class 10 UHS-1 Flash Memory

To get it to work with the NOOBS method, partition the card into four parts, or just one smaller than 32GB and format the first part as FAT32 and copy the NOOBS files to it. The issue with big cards like this is that SD Formatter or the OS disk utility will always format them as exFAT because of th...

Re: Raspbian has Ruby 1.9.3 already installed, why? Why so o

Yes, RVM was my tool of choice but apparently the community has switched to RBENV, which actually does what you need. You can run different Ruby versions with a fine granularity (folder, subfolder, etc...) like the name says RBENV is an "environment" the actual ruby installer is a module of that and...

Re: Raspbian has Ruby 1.9.3 already installed, why? Why so o

Oh thank you! Believe it or not, it was the packages that saved me. Used RVM (which apparently has fallen from grace) and then RBENV to install Ruby and this app that I ran just fine a couple of months ago. Wasted about 6 hours installing every version from 1.9.3-p551, 2.1.5 and the 'current stable'...

Raspbian has Ruby 1.9.3 already installed, why? Why so old?

I'm trying out a Ruby gem, and it took a lot of work to get up and running on Raspbian. It seems Ruby 1.9.3 was present, tried: "apt-get remove ruby1.9.3" only to find out the actual package name is ruby1.9.1 and it got updated. Searching a little deeper reveals a lot of packages if not all, are out...

Re: Using modern 'smart' USB Power Adapters with Raspberry P

One thing I remember is that the High Power USB port must be between 4.75 and 5.25 volts. The Pi signaling low voltage at 4.85 might be by design, actually signaling before it drops too low. What bugs me, is that I'm using these chinese 1.5$ 5v-2A USB chargers that don't blink at all while a 30$ 12W...

Re: Using modern 'smart' USB Power Adapters with Raspberry P

Hmm... So in theory one could solder some resistors to the Raspberry Pi 2 for example, to get it to 'negotiate' a higher current draw from 'modern' chargers? Because the two lines are unused on the Pi s they would't interfere with the current charging behavior? This is accomplished using two common ...

Using modern 'smart' USB Power Adapters with Raspberry Pi?

Pi / Pi 2 using modern 'smart' USB Power Adapters to supply power to the Raspberry? Once upon a time there was only one way to charge a usb device and that was done at 5V and 500mA max, or so I've been told. 'Modern' USB Power Adapters like the Apple 1Amp, 2Amp and 2.4Amp and many Samsung chargers u...
