This year's badge is a gypsum phone way brought entire phone on our backs.

This year we've deployed a our own Jetson network across the site.

So you've got a badge running Michael poison with WiFi.

Just a phone on Bluetooth headset compatibility.

You make phone calls between badges.

We think this is the first conference badges and phone has been deployed way spent the last six months, two years building.

This thing has been very late, and I have been done in here at the festival, finishing off soldering antennas, flashing for where's Right, carried up until the last minute, and we're finally handing out attendings today.

We're hoping everyone consider wraps its evolution of the badge from two years ago till tomorrow, Pie, which had the mark in the world, did you take CPU?

Second were quite chip and you take her phone module and you think, Oh yeah, we'll just put this on the board and then you start adding buttons on screens on sensors on the main processor on.

This badge has 128 pins.

We've used all of them, lost a 16 been poor, expanded into connect everything and get them all talking together.

On on.

There's been a lot of guys working on code way done.

A fresh sport of micro python to t eyes Latest MSP forth to e emcee.

You on T I releasing that on our version.

On top of that, with report should be released How everything will get back to my upholstery on Yes, making the first phone call a couple of months ago to Jonty was was like, Hello, I'm calling you from a badge And we finally had the first Budged badge phone call yesterday morning.

I'm not sure because I haven't played a lot with software.

As the PCB designer, you got full menu.

Should find a phone number, I believe.

No.

Yes, it's also it's tied into our arms like deck network.

So the badges of getting a four or five Did you I D, which could be full call from the decks network and should be finding a phone out and make phone calls.

I believe we can also do our vocals on.

They should incoming I'm not sure about.

We got anyone so work.

It's fine.

That was down.

That's what we got.

So you're back, You're back.

Covering up placing stuff In the centuries that guy's a mess.

People in 3432 e processor, right that we have eight megabytes of RAM external so that we've got a lot of extra ram to allow the micro APS on the APP developers, because you can write your own up.

I've got a lot of memories play around with this year just to the left.

Here we have a one megabyte serial flash it.

That's where all the app to get stored and safe in the bottom right hand corner is this is a WiFi area C C 31 20 which is their latest release of the white chip, um, on over the left hand side.

Here we have the same 800 c CS module SIM card, the gypsum antenna, which would have sold it.

We have the speaker.

We have the market firing on.

This is the Lucy's heads on center.

The microphones have a hardware disconnect so you can turn your microphone off so you make sure no one's talking imagined listing in this process on the SIM model of both hooked up to the speaker microphones.

We're hoping someone will be able to do from the CPU violet modem over Over the in Band Over the Analog with Peter B.

M Signals on D.

Telex, Maybe way have thanks to Seed Studio who sponsored the PCBs way have some growth connectors, which connects a C Studios Grove sensor modules.

They do 100 different breakouts around the bottom.

We have some pins broken out with reports and I to see and pins that the Zephyr doing conductive threads and wearable stuff.

So showing at Ladies Daniela to Fred's lanyard game, same pin's broken out on head is over here.

And then we have USB plug in for console one of my storage access to my story, um, on the front buttons, lots and lots of buttons.

So we have a 29 keep had laid out joystick menu Corman buttons, and then we have to near picks a lady so quite bright torch mode, much colors.

Previous badge had the same top curve, but was straight across the bottom of the screen was in landscape.

We had the menu of the A B and the joystick buttons.

So, yes, we've grown the board.

We still got a process er on a WiFi and we bolted on the GSM.

The pressure itself was changed.

We had an extra 32 2 years ago.

WiFi chip is the next generation.

We had C C 3100 last year.

This time we've got 3020.

We've thought the battery size to allow toe hopefully allow us to cover the extra power drawer from the from the GSM motive on the wife.

I was the same time.

It was a bunch of senses thrown on that for fun.

We've got a temperature and humidity temperature talked under their whole effect on there's a looks front from when we develop in the badge, we keep everything under wraps up until the last minute.

So I think the the announcement that we've built a phone went out on a post last week, a week before the rents of people start writing action coming up that side on all sense of pronounced the same time.

But it's not surprising that there is a A nympho booklet comes with a badge which got some snippets of code to go test and I ran with sensors and get you started under small soldier and projects.

There's a soldier, No idea, my sister.

So we don't absolve workshops here.

This is one of the production panels, and we've had to vision inspect all of these.

We've sat and looked every component back, 216 points on the back, her badge about 25 on the front.

And we've had to look over them, find components that have not been place properly or going through the open this line or missing opponents.

Because we're such a tight deadline.

Assembly sponsor Pacey deal were unable.

They didn't have time to do the inspection automatically, So we've done it here on site.

So the two of us have looked every board 300 panels, about 2100 individual baggies out 2.5 1000.

There were any calls a lot, which is where this boxes here of boards with pink dots where we've got a fault on the night center room can probably fix someone missing components.

It depends how hard it is to soldier on.

Some of them will be really tiny things.

We can fix them if we run low on the handing out.

We can start really fixing these.

And some of them were just leaving.

Um, it's almost ready.

Yes, we've revision expectable with then sold us a Montana Ron.

We've then been flashing firmware on the GSM module to enable the Bluetooth headsets It is.

The default phone went to enable the British had set ability.

So that's takes rounds a minute.

2.5 1000 minutes.

It's like 200 hours.

It's like five days.

So we've had five laptops going at it for a day and 1/2 on Got through all of those fantastically which we flashed the Get him from where we flush our firmware onto the M people think Michael Point comport.

Then it's kicks it up into a bag.

PCB.

Have a battery much guys Screen Volker Doctor.

Sticky bathroom on lanyards on hologram sim card on.

The attendees get to put it together themselves, which saves us a lot of time.

Way haven't.

It's a lot of people to put together on them and then go play past three batches.

2014 was Tilda Mark E.

Richards to point something, something something which is the speed of light.

Constant 2016 badge is Tilda Mark High because it was our third batch.

So 3.14159 so under the screen until the mark pi pi to 1000 decimal places they subversion number of this year way use irrational mathematical constant.

On this year, it's Tilden, Mark Delta, and the constant is 4.6 point on again.

I've got 1000 places on this year.

Found Bounds Delta Constant, which is related to qualification, population studies and chaos theory stuff, and I can never find a mask.

They consume lots of numbers.

Thes boxes make up 128 pins of the processor on all the interconnects.

So these are all all these connections go elsewhere.

I suppose I cheated.

I used my software skills for you to do that.
