Easiest thing is to go to a discount store (e.g. "dollar" store) and get one of those little USB battery backup things. Use its USB output to help power the Pi. Use its charge input to keep it charged. It should have overcharge protection built in. Now, how to get it all hooked up, I'm not sure. But...
Google has many incentives to ensure Android phones are updated, and provides incentives to manufacturers to do so. Unfortunately, there is a cost and manufacturers generally do not like to pay it. Ultimately, it comes down to how much (in)security consumers are willing to tolerate, and so far consu...
Actually, doesn't one of the WD PiDrive thingies do just this (be able to boot a variety of OSes off the hard drive)? I'd look into that as a solution that doesn't require physically swapping microSD cards.
I'd like to put Amazon Alexa on my AIY (which already runs a sort of Google Home) and somehow be able to select which one I talk to. So I'm interested as well.
The only other thing I want to say is it's easy to try a bit of hardware or software and feel it's "easy". Do a bit of soldering, read a data sheet, hook something up to an Arduino, and it's easy. Write a Hello World, respond to a web request, put an entry in a database, and it's easy. This of cours...
My understanding is that you can use two Pi Zero in USB gadget mode, each with a camera and some processing capability. They both would plug into a Pi 3. Maybe that would be enough processing power?
Won't the lighting require its own power supply and relays? Maybe just use an extra relay to provide power to the Arduino, controlling the relay from the Pi.
No idea, but this example https://tmrh20.github.io/RF24/pingpair_dyn_8py-example.html has: radio = RF24(22, 0) radio.enableDynamicPayloads() len = radio.getDynamicPayloadSize() receive_payload = radio.read(len) receive_payload.decode('utf-8') If the Python is just a wrapper, then it should have func...
I don't know if that includes building for Raspberry Pi. Note that you would still typically build for Raspberry Pi on Windows, Mac, or Linux (i.e. cross-compile).
What's eating up the education market around here (southern Ontario) is Chromebooks. A Pi 3 is $50 CAD bare, whereas a Chromebook is $250, and comes with an Intel Celeron chipset (handy for dual booting Linux using Crouton), 4 GB RAM, 16 GB SSD, USB 3, ruggedized case, display, keyboard, trackpad, c...
I work on both software and hardware. Remember that BOM (cost to manufacture) tends to limit hardware, on the one side. And on the otherwise, sometimes you have software writing software. In my opinion, software is usually more complex in general. But each case is different, and each domain brings w...
Thanks for all the tips. Trust me I'm not new to computers or to Linux. What I was most interested in, was people's experience running the Pi as desktop and advice for doing so, which a few of you have provided. I'd be curious to know if Chromium has any settings which can be tweaked. As it happens,...
I was hoping to, someday. I was thinking of using one of the older Apple Wireless Keyboards, without numeric keypad, to put in as the keyboard, since it's quite thin (once you remove the place for AA batteries of course).
I removed the CPU usage monitor from the LXDE top panel, and instead added the resource monitor, which can graph CPU and memory usage, so I could keep an eye on it. (Maybe that should be default.)
I'll try gpu_mem=256 for a while and see how it goes. (Default is 64.)
Understood. My OCZ Vertex 2 is apparently around 250 MB/s. The SD card maxes out at 40 MB/s (interface limitation). So it could be faster, but not that fast, because USB 2 itself is limited to 60 MB/s, but I'm reading that practical limit is only about 40 MB/s. And it's a shared bus. :-( Really need...
So an SSD through USB? Will that be faster? What's the fastest MB/s I could get for read/write, assuming a sufficiently fast SSD? (I have an OCZ Vertex 2 I could use.)
I've been experimenting for a week with using the Raspberry Pi 3 as my desktop, using the latest (Sep 2017) Raspbian. As you can imagine, the challenges are limited CPU, and low (1 GB) RAM. I am keeping htop running in a terminal so I can monitor the CPU usage of all 4 cores, and also the memory usa...
