Re: Alernative ways to power a Pi

Solar power (photovoltaic) panels convert _solar_ wavelength photons into electron flow, which are from primarily toward the red end of the visible spectrum due to the physics of the materials used in the panels. Fluorescent lights actually generate mostly UV internally in the bulbs, and the phospho...

Re: Debian Jessie with PIXEL desktop i386 for PC and Mac

I may have missed it being posted, and searches haven't returned any appropriate results, but does anyone know the path where the persistence files are stored on a PC when that option is chosen at Raspbian PIXEL x86 boot time? If there are multiple drives on the PC, which one are the persistence fil...

Re: CM3

Since people keep asking when the CM3 will be available and no one seems to have paid any attention to my post from December 12th, I'll repeat the appropriate portion here:

Re: CM3

I am more interested in the CM3 than the CM3L, as I like having eMMC for the boot drive - in my experience, plant operators will often remove any removable media... That's what environmentally-sealed enclosures are for - just keep the card invisible to the denizens of the environment as well as the...

Re: CM3

Are there mods to use a CM3 with the older dev board? The CM3 will reportedly work with the Original Flavor dev board if additional current is provided via beefing-up (via a jumper, I'd guess) that's required for the CM3 (and certainly the NEC CM3-16GB) via vbat. However, the CM3 Lite will need the...

Re: Compute module 3 datasheet

Thank you very, very much for that. The CM3L is a surprise. The 4GB eMMC for the CM3 is a mild disappointment, but I'm glad to know for sure that that is what it will have. The purpose of the CM(3)(L) is embedded applications, so it won't need a full Raspbian distro for those. Something like a lapt...

You are a smart person to criticize because that wouldn't be very secure.

Folks, a small point in accuracy in terminology. _Altitude_ is what we pilots use to ensure our aircraft are always _above_ terrain and water! _Elevation_ is the term for measurement of a surface above (or below, in the case of Death Valley, for example) sea level. So, please replace all of the term...
