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 :-)

Pattern recognition.

ðeshipu says:
complex monomers

baldengineer says:
lol

ðeshipu says:
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...

Developping raspberry as a Software Radio Defined (rpitx). Could it be possible to design a 50ohm line to pin header (PWM and GPIO4 ) ?

Are you sure? yes | no

Dan wrote 03/16/2018 at 19:51

To leverage the hardware video acceleration for 1080p playback on the Pi (e.g. compiling VLC/FFmpeg/etc from source), is the preferred/better way to leverage OpenMAX IL as was done years ago or to use MMAL?

Are you sure? yes | no

Peabody1929 wrote 03/16/2018 at 19:48

How about a SATA connector for SSD support? A 120GB-512GB drive with simple plug and play would be nice.

Are you sure? yes | no

César Héctor wrote 03/16/2018 at 19:20

I'm from Perú currently working on a project to develop a cheap-as-possible teaching laptop and we've only got about three weeks, we've chosen to use Raspberry Pi 3 Model B+. Got any recommendation?

Are you sure? yes | no

ted wrote 03/16/2018 at 19:15

How do individuals/businesses get on the pre-launch program (under NDA)? Gina of OctoPrint should really be provided with an eval model before the launch date.

Are you sure? yes | no

ted wrote 03/16/2018 at 19:12

What's your favorite type of pie?

Are you sure? yes | no

Evan Juras wrote 03/16/2018 at 19:12

How much has Raspberry Pi's user base grown over the past three years? Is the growth rate of Rasbperry Pi users increasing, flattening out, or declining? By how much?

Are you sure? yes | no

ted wrote 03/16/2018 at 19:11

Why has ADC not been added? Why no official support of getting the voltage level (even though it's obviously there)? What about allowing a flexible voltage input (e.g., putting a regulator on board)?

Are you sure? yes | no

ted wrote 03/16/2018 at 19:08

Officially or not, how tolerant is the GPIO to 5v?

Are you sure? yes | no

Evan Juras wrote 03/16/2018 at 19:08

Are there any plans to create an improved Camera Module V3 any time soon? Would it be possible to add an auto-focus feature?

Are you sure? yes | no

Nathaniel Evry wrote 03/16/2018 at 19:07

Is there a good place to sell / donate old pi boards as I upgrade? I have 8 rpi zeros, and 2-3 B's looking for homes.

Are you sure? yes | no

This is a great question!

Are you sure? yes | no

Are there plans for a SATA connector for the Pi?

Are you sure? yes | no

nightduck wrote 03/16/2018 at 19:05

1) What's the plans on USB-C? (Maybe to replace the charging port)

2) Any hope for an embedded graphics revision? Or do I have to stick with Nvidia Tegra?

Are you sure? yes | no

Thomas Shaddack wrote 03/16/2018 at 19:03

Any way to increase filesystem reliability, make the thing more resistant to powerdowns?

Are you sure? yes | no

anfractuosity wrote 03/16/2018 at 18:56

Will you consider adding non-usb ethernet and usb3.x at some point? Cheers!

Are you sure? yes | no

Brian MacLeod wrote 03/16/2018 at 15:43

Is there any likelihood of doing a board that will accept multiple Compute Modules? That way we can have clustering on the cheap :)

Are you sure? yes | no

deʃhipu wrote 03/15/2018 at 11:15

Are there any plans for having build-in power management in future versions? Even a simple shutdown button would be a huge help.

Are you sure? yes | no
