Roger Thornton will be co-hosting the Hack Chat this week. This Hack Chat is at noon PDT, Friday, March 16th.

Time Zones got you down? Here's a handy count down timer!

It's Raspberry Pi's 6th birthday, and we've invited them back this year to talk all things Raspberry Pii!

Ever wondered how Raspberry Pi can make their products so cheap, so good, and provide such good community support all at the same time? Now's your chance to discuss, ask questions, give feedback or compliments about the product.

Roger works for Raspberry Pi as Principal Hardware engineer where he oversees design, test, compliance, and production for Raspberry Pi products.

Previously working for Broadcom where he was part of the team who characterized and tested numerous SoC’s including BCM2835/6/7; the processors used on the Pi. He also has experience of the Smart home and IoT from his time working in a Cambridge consultancy where he helped deliver a series of dedicated Smart Home energy monitoring and automation chips to market.

Here's the link to our chat with Roger in 2017!

In this chat, we'll discuss:

  • The future for Raspberry Pi products
  • Pi events around the world
  • Where can you buy a Pi Zero in quantity?
  • Questions and answers about your favorite products!

    @Patrick Van Oosterwijck unpopular

    Roger Thornton You could but you'd have some big bottlenecks in terms of getting data to and from the external GPU

    nightduck +1

    next q from @cesar : Is there a way to use an external GPU with the Raspberry, for computational purposes?

    Roger Thornton External GPUs; You could but you'd have some big bottlenecks in terms of getting data to and from the external GPU

    ðeshipu we have some time dilatations again

    Evan Juras+1 to @Patrick Van Oosterwijck :)

    Frank Buss I wish the Raspberry Pi would have something like the BeagleBone PRUs, 200 MHz 0 latency RISC CPU for controlling the GPIOs

    nightduck Those exist

    ðeship why bot use BB then?

    nightduck Buy a beaglebone

    Thomas Shaddack 
    +1 to @Frank Buss

    Evan Juras 
    thanks for linking that @nightduck , I was going to PM you about your question

    Frank Buss 
    lol

    ðeshipu 
    no need to make all hardware the same

    ðeshipu 
    BB also has the advantage of not using a Broadcom CPU

    last question from @Paul Anaya : Roger, Happy Friday! Do you think you may consider adding eMMC boot to future Raspberry Pi models like ASUS is doing with their Tinkerboard S?

    nightduck
    And moar GPIO pins

    Frank Buss 
    and it has even a full KiCad schematic and board layout

    ðeshipu 
    luxurious

    sfrias1 
    +1 @ðeshipu

    Frank Buss 
    but this is the Raspberry Pi chat, at least they have a bigger and good community :-)

    ðeshipu 
    community won't power your project

    Roger Thornton 
    Unlikely at the current price point, we do sell Compute modules with eMMC on them if you wanted to use that. The main board can't support the cost adder

    sfrias1 
    OK. thanks for @Roger Thornton

    ted 
    I thought a teaser about this chat was "Where can you buy a Pi Zero in quantity?"

    Thomas Shaddack 
    backward compatibility with the OS is also handy. i fried a raspi 3 couple days ago (12V to the USB, grounding fault of a ramps/arduino module), the usb handling chip literally exploded. had only one, replaced it with a raspi 2 and it worked immediately, albeit slower.

    sfrias1 
    Haha

    Thomas Shaddack 
    can the main board have some sort of a miniature solderable line of pads for attachment of things like emmc yourself?

    Patrick Van Oosterwijck 
    +1 @ted

    Sophi: This concludes our Raspberry Pi Hack Chat!

    Roger Thornton 
    The buses that would be connected to this are both used (SDIO) one to SD card and the other to Wifi. We won't be putting pads down but if you felt adventurous you coudl try tacking one on the lines!

    Thanks for coming everyone, and especially thanks to @Roger Thornton

    Patrick Van Oosterwijck 
    No, that Pi Zero volume question must be answered

    Peter 
    I have to give two thumbs up to the RPi team. I was wondering what I was going to do with my first one. My children soon showed me. ;-). I was laughing as I tried to order the new 3B+. Thanks everyone!

    Pabluski 
    Thanks!

    Evan Juras 
    thanks Roger!! you did a great job handling the deluge of questions. see you next time!

    feel free to stay and chat

    Boian Mitov 
    Thank you @Roger Thornton and @Sophi Kravitz :-)

    never really finished it, the gibberish got on my nerves

    Thomas Shaddack says:
    yay espionage!

    Sophi: welcome to the Raspberry Pi Hack Chat! My reminder email just went out, s we're going to start at exactly.... 6 minutes after the hour

    Please put all qs and comments here: https://hackaday.io/event/69365-raspberry-pi-chat

    Stephen says:
    Hey all! Excited for the Pi chat!

    XabiLopez says:
    Hello everyone!

    Shayna says:
    Hey y'all

    baldengineer says:
    before we get started, slightly off topic but related. does any know how to control the Undervoltage icon directly? (I want to be able to turn it on.)

    ðeshipu says:
    icon?

    ðeshipu says:
    like a holy painting?

    ðeshipu says:
    or is there some context to your question that you forgot to mention? some kind of software maybe?

    Evan Juras says:
    im excited for the Raspberry Pi hack chat! yay! thanks for sending out the reminder email, Sophi :)

    baldengineer says:3:04 PM
    deshipu the pi displays several status icons, which I understand are driven directly from the GPU. one is undervoltage, monitoring the 5 volt rail

    anfractuosity says:3:04 PM
    status icons?

    baldengineer says:3:04 PM
    all references I find are people asking how to disable it or understand it.

    ðeshipu says:3:04 PM
    @baldengineer it only displays a text console for me

    ted says:3:04 PM
    so ironically there's ADC on the board, just not in the pins :)

    baldengineer says:3:05 PM
    okay, nevermind. i don't want to distract before we start. search "pi lightning icon" to see what I mean

    Liam Kennedy says:3:05 PM
    Who here has ordered (even received) their first Pi 3B+?  (I received shipping confirmation from Newark Element14 yesterday)

    DrivenMadz says:3:05 PM
    Packing frantically packing for shoeshoe trip to Mt Rainer :) still got it chromcasted to the TV :) Happy Friday everyone :)

    srivishnu piratla 
    im still looking where to buy a 3B+

    Sophi: Happy Friday! :) welcome to the Raspberry Pi Hack Chat w @Roger Thornton

    Roger Thornton 
    Hello all, good to be here/

    Liam Kennedy 
    Try element14.  Good price ($35) unlike CanaKit that is up to $44 + $13 shipping

    I'm sure more stragglers will show up soon, but we can get started. Roger- tell us who you are and what you work on at Raspberry Pi

    Liam Kennedy 
    Ummm.. Sophi... so we have to JOIN that other event thing to post questions there?

    Roger Thornton 
    I am one of the hardware engineers at Raspberry Pi, where I've worked for nearly three years. I am the designer for Pi Zero W and the very recently launched Pi3+

    ðeshipu
    love the pi zero w! great job!

    Liam Kennedy 
    Thanks for being here Roger... So you are based in the Cambridge (UK) offices?

    baldengineer 
    Nice work!

    Boian Mitov
    Hello everyone :-)

    Roger Thornton 
    Yes, I am based (and live) in Cambridge

    Liam Kennedy 
    Cool  (p.s.  I grew up in Haverhill.. gaaaahhh :-)

    hey @Liam Kennedy !

    Liam Kennedy 
    Hi @Sophi Kravitz  back!!

    Liam Kennedy 
    Awesome work on the 3+ (I will now always refer to it as 3+ .. and save the extra typing of 3B+)

    Roger Thornton 
    Thank you, it was a long journey but very happy with end product

    how long was the design cycle?

    Liam Kennedy 
    What was the "trickiest" part of the design for you?

    Roger Thornton 
    We started work on it early Jan 2017, there was a couple of...

So, I'm guessing we can put questions there. In this case:

1) What's the reasoning behind only releasing a part of the schematics?

2) Are there plans for opening up the DSI interface? If not, what are the obstacles?

  Are you sure? yes | no

Patrick wrote 03/13/2018 at 19:48 point

will there be recording available after the event? Perhaps as a podcast?

  Are you sure? yes | no

Lutetium wrote 03/14/2018 at 14:05 point

Hi Patrick, we'll be posting a transcript here on this page

  Are you sure? yes | no
