Re: PoE+ support?

As far as I can see, none of these come close to 3A output @5V

I did rather a few hours of googling before asking here ;)

PoE+ support?

Hi I'm working on a project where we need PoE, and probably PoE+ to power a bunch of pi3's. They are connected to and drives a 7" touch display, so the minimum current is specified as 2,5A, meaning we should probably have 3A just in case. PoE+ supports 30W, so no problem, but I'm unable to find much...

Re: Still only one rpi zero per purchase?

> You can order multiple RPI Zeroes with presoldered headers from modmypi ( 20x ) and pisupply (no limit ?)
but you pay an extra £4-5 each for that:

Seems there's a limit of one on those too

Re: Still only one rpi zero per purchase?

Thanks for the links. As for the $5 price, that's not really the reason I want to get these, only that they are better suited to what I want than for instance an Orange Pi. I don't have a problem paying a bit more for good hardware.

Still only one rpi zero per purchase?

Hi

I'm a bit confused, but why on earth is it only possible to purchase a single Raspberry Pi Zero? I need a few of these for a project I'm working with, and without it, I'll need to get some chinese rubbish instead, which obviously works, but isn't nearly as god.

Re: Pros and cons of Ubuntu Mate vs Raspbian

> Raspbian is more a tinkers OS, can make LEDs flash etc. Raspbian is just a Debian port, and no much of a "tinkers OS" than debian is (nor any other usual distros (unless you use slackware or gentoo)). It doesn't "make LEDs flash etc". All those packages are in the normal debian repos, beleive it o...

Re: Cycle computer

How did this project go? I'm planning something similar with an arduino doing data collection from a temperature/humidity sensor (DHT-22), a gyro/accelerometer (MPU-6050), voltmetering (both the 5V and my 36V ebike battery), magnetic sensors for both wheels and crank, feeding an either a pi zero w o...

Re: Wishlist

Before I get into your wish list I just want to note that this is a recurring type of topic. The threads don't last long before devolving into acrimony and get closed. I think that's a pity because I rather like a good speculation discussion. That may be because I've been reading science fiction fo...

Re: Wishlist

Also, most UPSes just provide power in case of downtime, they don't generally have surge protection. I once saw a bunch of machines (all behind enterprise-level UPSes) getting fried by a 4kV surge (the UPSes just paniced and went into passthrough)

Wishlist

Hi all I'm using rpi for a number of things, now also including some infoscreens at work (just a couple of them so far, probably 50 in a few months). I have a few points on a wishlist that would be nice to have on a new pi. I guess most of these have been discussed earlier, but I couldn't find a gen...

It would be very nice indeed. Unfortunately, I don't know the libav(codec) codebase (and I'm a rather lousy programmer)…

Re: Using the H.264 encoder?

The Pi is just a bunch of electronics, can not do anything what-so-ever, except light up a few LEDs on its own.. Various Operating Systems do have H264 compatibility http://www.raspberrypi.org/phpBB3/search.php?keywords=h264+encoder Totally useless post. Try answering the question. Why is it useles...

Using the H.264 encoder?

Hi all

I read the Pi has an onboard H.264 encoder. Now, how can I use this? I was planning to use avconv (from libav, an ffmpeg fork), but no support exist for this. What else can be used?

thanks

roy
