00:00:00,000 --> 00:00:06,740
We are in the Aerospace Village at DEF CON 30 checking out the Aerospace Badge, which you're the designer of.

2
00:00:06,740 --> 00:00:07,080
I am.

3
00:00:07,080 --> 00:00:08,380
Cyber Test Pilot.

4
00:00:08,460 --> 00:00:09,640
This is great.

5
00:00:09,640 --> 00:00:15,580
So what I love about it is the fact that there's not one, not two, but five SAO ports on it.

6
00:00:15,580 --> 00:00:17,720
Can you tell me what you did on this badge?

7
00:00:17,720 --> 00:00:18,300
Certainly.

8
00:00:18,300 --> 00:00:22,020
So this is the third year the Aerospace Village has made a badge.

9
00:00:22,180 --> 00:00:25,840
And, you know, with the pandemic, microcontroller chip shortage, right?

10
00:00:25,840 --> 00:00:34,360
And so knowing that the theme of DEF CON was going to be community, like we're doing all these meetings, like what could we do with limited product?

11
00:00:34,640 --> 00:00:41,920
And so kind of something we came to the idea on, and all coalesced to, was the whole shitty add-on platform, right?

12
00:00:41,920 --> 00:00:43,420
It doesn't need a microcontroller.

13
00:00:43,420 --> 00:00:46,040
The parts to, like, support it are fairly ubiquitous.

14
00:00:46,300 --> 00:00:59,120
And then it was also, like, very serendipitous because we could take the idea, the concept of a shitty add-on, and we can export it to other volunteers within the organization, right?

15
00:00:59,120 --> 00:01:00,500
You're saying within the Aerospace Village?

16
00:01:00,500 --> 00:01:03,100
Within the Aerospace Village, so the core volunteers.

17
00:01:03,100 --> 00:01:07,680
And so what we ended up doing, myself, I was working with pubs and some others.

18
00:01:08,160 --> 00:01:10,440
We did a lot of iterations back and forth.

19
00:01:10,440 --> 00:01:14,820
I had worked with my same artist friend, Dan Ropp from Fly Surreal.

20
00:01:14,820 --> 00:01:19,000
And he had done the artwork, and then we really liked the layering.

21
00:01:19,000 --> 00:01:23,700
So you can get, like, the PCBs are stacked, so you can get kind of, like, that diffused glow.

22
00:01:23,700 --> 00:01:30,340
Yeah, I noticed that one of the things I really like about it is, as you say, it doesn't look like there's tons of microchips or something like that.

23
00:01:30,340 --> 00:01:32,120
It's a very simple board.

24
00:01:32,120 --> 00:01:33,200
It is incredibly simple.

25
00:01:33,200 --> 00:01:37,880
But what's so cool about this is you focused on the art of the badge.

26
00:01:37,880 --> 00:01:39,700
You focused on the multi-layering.

27
00:01:39,800 --> 00:01:40,880
You focused on these...

28
00:01:40,880 --> 00:01:44,400
I really love the clouds on it because they stick out.

29
00:01:44,620 --> 00:01:46,200
It's not like a simple circle.

30
00:01:46,200 --> 00:01:49,820
Normally, on badges, you're like, circle, square, circle, square.

31
00:01:49,820 --> 00:01:55,240
With these, you have these nice, cool cutouts, and then you have the art, like, with the constellations, the clouds.

32
00:01:55,880 --> 00:01:59,760
Yeah, like, a complete kudos to my friend who did the artwork.

33
00:01:59,760 --> 00:02:02,800
Like, he did the outline and the shape, and I loved it.

34
00:02:02,800 --> 00:02:03,440
It came together.

35
00:02:03,440 --> 00:02:05,060
We went back and forth on the colors.

36
00:02:05,060 --> 00:02:07,540
Like, the purple against the black, we had to keep it.

37
00:02:07,540 --> 00:02:09,360
It looked better than white, right?

38
00:02:09,360 --> 00:02:13,340
Now, one of the questions I have also with this is, it's a multi-layer board.

39
00:02:13,340 --> 00:02:16,280
I'm assuming people have to assemble it themselves, or are they coming together?

40
00:02:16,280 --> 00:02:19,940
We assemble them ourselves, so we use a volunteer organization.

41
00:02:19,940 --> 00:02:25,320
So, we had a partner back in Maryland, and we had their lab space, and we just solder parties.

42
00:02:25,420 --> 00:02:26,420
Oh, goodness.

43
00:02:26,420 --> 00:02:27,860
How are these things actually attached?

44
00:02:27,860 --> 00:02:29,220
Oh, that was clever.

45
00:02:29,220 --> 00:02:29,600
Yeah.

46
00:02:29,600 --> 00:02:33,860
So, you just did little extenders through each one and then soldered them all together.

47
00:02:33,860 --> 00:02:34,600
Terminal pins.

48
00:02:34,600 --> 00:02:39,000
So, the silly add-on standard is, you know, the two-by-three and six-pin connections.

49
00:02:39,180 --> 00:02:41,460
And so, it's, you know, two and two.

50
00:02:41,460 --> 00:02:44,520
It gives it stability, you know, separating them.

51
00:02:44,520 --> 00:02:53,720
And then the same connections are carried through the terminal pins to the next subsequent layer of board so that we can get the SAO.

52
00:02:53,720 --> 00:02:55,980
That was incredibly clever.

53
00:02:55,980 --> 00:02:56,600
Yeah.

54
00:02:56,600 --> 00:03:04,760
Your mounting ports are the ones that hold up the board, and then you're leveraging those not just to hold up the board, but also the SAO ports.

55
00:03:04,760 --> 00:03:07,880
Yes, so that they carry the signal and they're structural, right?

56
00:03:07,880 --> 00:03:11,300
So, included in the board, you also have your own add-ons here.

57
00:03:11,300 --> 00:03:11,740
Yes.

58
00:03:11,740 --> 00:03:15,920
So, the lanyard, the five ports, the space shuttle.

59
00:03:15,920 --> 00:03:20,620
We have this removed before flight, and so it comes with the ability.

60
00:03:20,620 --> 00:03:23,900
It's unsoldered at purchase, at donation.

61
00:03:24,400 --> 00:03:27,640
And so, you can orient the removed before flight differently.

62
00:03:27,640 --> 00:03:36,140
So , like, ideally, someone, what they could do, right, is if they could integrate that into the DEF CON badge.

63
00:03:36,140 --> 00:03:37,320
Did that turn on?

64
00:03:37,600 --> 00:03:38,500
There we go.

65
00:03:38,960 --> 00:03:40,320
Oh, you know what I've done?

66
00:03:40,320 --> 00:03:41,480
I've hacked my warning light.

67
00:03:41,480 --> 00:03:42,300
That's the only reason.

68
00:03:42,300 --> 00:03:44,420
I'll explain that, why.

69
00:03:44,640 --> 00:03:50,060
But the idea is, we kind of had a head start that the DEF CON badge was going to have a port.

70
00:03:50,060 --> 00:03:59,140
And so, we were wondering, like, you could orient, you know, in multitude different ways, so that you could get a silly add-on, you know, not blocking a baseboard.

71
00:03:59,320 --> 00:04:01,160
The microchip shortage.

72
00:04:01,420 --> 00:04:02,700
My badge is different.

73
00:04:02,700 --> 00:04:04,740
I've hacked it, but this was intentional.

74
00:04:04,760 --> 00:04:11,660
So, this microchip is unpopulated for the normal sale, but it fits an ATTiny85.

75
00:04:11,980 --> 00:04:17,640
It maintains the silly add-on standard, the clock line, data line, pin one, pin two.

76
00:04:17,640 --> 00:04:22,220
And so, what I've done is, I've hacked my warning light.

77
00:04:22,340 --> 00:04:26,760
So, it's very tiny, but you cut a trace, and then you jump a trace.

78
00:04:27,040 --> 00:04:33,340
And all that does is it moves the voltage from the LEDs, from the voltage line, over to GPIO1.

79
00:04:33,340 --> 00:04:33,900
Oh, okay.

80
00:04:33,900 --> 00:04:38,080
So, it's, you know, it's a silly add-on, but this is why mine blinks.

81
00:04:38,080 --> 00:04:39,800
A normal one wouldn't.

82
00:04:40,340 --> 00:04:41,240
Oh, that's very cool.

83
00:04:41,240 --> 00:04:42,500
So , it's hackable, right?

84
00:04:42,740 --> 00:04:44,980
So, we do things with the badge.

85
00:04:44,980 --> 00:04:48,040
There's a few, like, puzzles on here.

86
00:04:48,260 --> 00:04:52,600
So, this is the airport of the Harry Reid Airport here in Vegas.

87
00:04:52,920 --> 00:05:00,980
I recently visited the Outer Banks, and so the Wright Brothers, first flyer there, homage to the first flight.

88
00:05:01,160 --> 00:05:10,460
And then this is kind of silly, but this is a barcode boarding pass, and it's for Buzz Aldrin to board Apollo 11.

89
00:05:10,460 --> 00:05:10,880
Oh, that's so cool.

90
00:05:10,880 --> 00:05:13,740
So, it's just fictitious information put in there.

91
00:05:13,740 --> 00:05:16,260
But it's present for someone to discover.

92
00:05:16,260 --> 00:05:17,180
This is so cool.

93
00:05:17,180 --> 00:05:18,140
Thanks for making something.

94
00:05:18,140 --> 00:05:27,220
I love the fact that these SAOs are really becoming more popular and really pulling in a lot of the cool art that you get to see on circuit boards.

95
00:05:27,220 --> 00:05:29,220
Thank you so much for designing it.

96
00:05:29,220 --> 00:05:32,980
Thank you for watching, and as always, hack on!
