Monday August 23 meeting: another solder party

I was hoping to demo a laser engraver for this week’s meeting, in addition to assembling the last of the preordered Tree of Life badges and prepping the rest for stocking and immediate sale. But Amazon sent me a BabyTrend mini nursery instead of the laser engraver I asked for.

So the agenda for tomorrow evening is: meet at the usual space, work out a minor assembly line, and knock those out. It will be far easier than last time — I should have most of the front boards already assembled before then; and the castellated edge solder method is much, much faster than using pin headers, and leaves the back side of the badge much smoother.

There will also be some discussion of prototyping to try out a feature for next year’s badge. I ordered some Space Dust, but I’m low on other beers, so if Space Dust isn’t for you, and you’re not into Malört, Skrewball or Woodford, consider bringing something.

Meeting ON this evening

Meeting at the usual place this evening. Sorry for the late notice. Was traveling, got in late last night, really wasn’t sure what I was up for. But I got hot tweezers and I’m dying to try them out. And some folks who didn’t go to vegas might be interested in badge&stickers show&tell. Also there may be some front-side badge soldering.

Meeting will be hybrid on Discord as well. But you can’t taste Malört through a screen.

Or maybe you can.

If you’re new to the group, hit me up via DM on the Discord or on Twitter if you’re interested in attending. If I met you in LV, mention that. Otherwise, generally we like to get to know people a little bit before inviting them to the private space.

Boundaries, directions, and taking it farther

I wanted to take a moment to give a little guidance to all of our new followers now that Defcon is over and everyone is resting before catching up on everything. Our twitter followers tripled in the past 28 days, and I realized new followers are coming from all sorts of different angles.

Hi. I’m Baab, sometimes Baabalicious, sometimes just Bob, and sometimes just DC540. I put out feelers for starting this group three years ago. Immediately lured in some quality people who brought intelligence, passion, curiosity and out-of-the-box thinking. The collaboration has been beneficial for all of us, I like to think.

We got the idea for doing a badge probably after DC27. We kind of faded in energy when DC28 was announced as all-virtual, so the badge idea just dragged along. But as DC29 approached and it became clear there would be an in-person component, we became energized again. On May 24, 2021 (yes, just over ten weeks before Defcon opened, we had a planning meeting, wherein we attempted to nail down specifics. The whiteboard at that meeting is attached to this post. We had wanted it themed for Hitchhiker’s Guide, but none of us came up with a structure or shape that really called out to us or that we found compelling, so it was still feeling a bit in question. After everything went home that evening, I sat down to do some reading and kind of had an epiphany.

I realized that the general shape we had settled on, which I was already uncomfortable with just because it didn’t holler “pick me” when I looked at it with my mind’s eye, seemed as if it would perfectly accommodate a Tree of Life arrangement. This made me nervous. I was well aware that some of the members of the group may have come from a religious background that might lead them to feel uncomfortable around such symbolism. So I tended to tread lightly when approaching the group with this idea. I came up with some mockups, and either they were too busy to respond or I can be ridiculously persuasive at times, because I got no pushback, and continued to develop. As usually happens with this type of group project or volunteer/nonprofit organization, the person with the most forward momentum tends to get what he or she wants. At a certain point it had gathered so much momentum that it had to be completed.

And here we are. We have presented to the Defcon community an esoteric artifact, on behalf of a group who mostly has no historical involvement or investment in such esoterica. And it’s been remarkably well-received. It led to a lot of interesting doors being opened at the con, and some great conversations. I suspect the acquirers had varying reasons for desiring this badge. Some because the backlit presentation with a black solder mask created an especially appealing aesthetic; some because they appreciate anything esoteric; some because they gotta have ’em all, and some, well, who had spend considerable portions of their lives in the study of the badge’s subject matter.

What is Kabbalah? Well, it’s a lot of things to a lot of people. And it’s not the same to all of them. The way I like to describe it to people with no background at all is, “It’s a framework for interpreting the world around you.” In Judaism (I’m not Jewish), it’s been around for hundreds of years. It has been adapted by others, probably most notably Aleister Crowley, and you’ve probably noticed it associated with celebrities like Madonna. It’s not my role to attempt to give you a definitive answer, that would take a whole new website, or maybe a whole new career. But if you gave me enough money, I would try. 🙂

I think maybe I was initially attracted because, you know, spooky occult. But I came back to it from a pure hacker standpoint. It’s like when my family bought a sailboat eight years ago. As a hacker, if you love boats, you will love sailing. It’s a hobby where you can learn something new every day you do it. There are lots of techniques, strategies and optimizations to geek out on. Same with Kabbalah. No matter which angle you approach it from, there is an endless amount of knowledge and information behind it. I met several people during con who have studied it for decades.

I will say this. Based on my own personal research, a fantastic and humorous introduction to Kabbalah, also known as the Tree of Life, can be found in The Chicken Qabalah of Rabbi Lamed Ben Clifford: Dilettante’s Guide to What You Do and Do Not Need to Know to Become a Qabalist by Lon Milo DuQuette. (affiliate link) At the very least, this book should give you an idea of whether Kabbalah (also spelled a bunch of different ways, blame Hebrew ambiguity) is something you’d be interested in studying.

How does this connect with, and why does it resonate with, the Hacker community? This question came up during a talk I was invited to participate in during Defcon. (It was a private talk, don’t get your FOMO in a bunch). I think it was actually during that talk that it sunk in, and I mentioned it, that I think the seeds of this interest were planted in the textfile BBSes many of us frequented back in the day. Who remembers “The Occult Technology of Power?” Every textfiles BBS had subcategories. Hardware, phone phreaking, piracy, occult, basically everything us hacker kids felt was suppressed knowledge. So maybe some of us dabbled back then. Maybe some of us deep dived. Either way, here we are.

Going forward. As I mentioned before, the members of this group come from different religious backgrounds, and it’s not fair to them to attach any prejudices associated with this badge to them, so going forward, I’d like to separate this out a bit. This might go even farther in the future, but for now, the official DC540 website (dc540.org) and Twitter (@dc540_nova) will focus on the badge hardware, functionality, software updates, and the game we released. P.S., nobody has won yet!

For deeper conversations on esoteric or related matters, to exchange related resources or suggestions, or to continue friendships made at Defcon, or to get random shitposts now and then, hit me up on my personal account (@dc540baab). I met some very interesting people at Defcon, both badge-related and not so much, and I’d love to the continue the conversations. The general rule is, if it relates to something the group gets behind, it’ll go here. If it’s something I think might be controversial to the group, it goes to my personal. I don’t want to scare new group members away with what are essentially personal pursuits.

OK, enough of my too-long-for-twitter babblings the day after returning from Con.

Badge Distribution Update

So I just left the badge creator’s meetup. Amazing talking to other badge makers and doing a few swaps, buys and sells.

Right now, I’m taking a much-needed self-care break. I have to recharge my phone, mask and body for a bit, sit with my feet up for a while, and get shower of the day.

My plan for the rest of the day is to be available to hand out preorders.

I’ll leave the room in like an hour and a half or so, and head down to the main chandelier bar on the Paris casino floor next to Cafe Americano, find a comfortable seat and hold court for any pickups. If any of you are really desperate to pick it up before then, hit me up directly (Twitter @dc540_nova) and I’ll give you directions to the room at the Linq. Extra stickers and support points for life if you pick me up a mocha doubleshot from the convenience store on the way up. It’s about $7. I’ll pay you for it.

PINECIL soldering iron for the win!

So I dropped my TS-80 portable soldering iron on the tile kitchen floor last week, and broke the glass covering the OLED. It still works, but it spooked me, because of and the upcoming Defcon trip. Very bad timing. I wanted to make sure I had a backup in case we need to fix anything on the fly, or solder new stuff, etc.

I looked into getting another one, because I’ve been pretty happy with it, but then I found some posts touting the PINECIL. At about 1/3 the price of the TS-80, supports open firmware and custom logos just like the TS-80 and TS-100, and pretty well-reviewed.

So I got a PINECIL. It showed up last week. I plugged it into the same battery pack I’ve always used for my TS-80 (since fall 2018!), and it reported low voltage. Looked into it, and it turns out the PINECIL needs more juice than something made in 2018 can push. From multiple sources, the PINECIL really works its magic when it’s getting 60W at 20V. So now I need a new battery to power my new iron.

You should totally buy one. It’s just $35. https://amzn.to/3lqKDlp

I spent a couple hours looking at battery packs, specs, reviews, the whole bit. I finally settled on the EasyLonger model. 65W USB-C PD, 10000mAh. It’s important to stay below around 30000mah if you want to take it on a flight with you.

First test, fires right up, pumps the iron right up to the optimal temperature.

You should totally buy one, it’s about $55. https://amzn.to/2VhXpIj

Also get a high-capacity USB-C cable. The one I got is rated for 5A.

Maximizing the benefits of castellated edges

When we chose our badge design, we were cocky and full of ourselves, and went with surface-mount pads on our prototypes. Because our badge is based on the RPi Pico microcontroller, and had castellated edges, we figured we would minimize soldering, maximize space for silkscreen artwork, and up the cool factor by mounting on the pads using solder paste with the castellated edges.

Well, that turned out to be too hard. We don’t know what we’re doing, and didn’t have time for a learning curve, and kept running into bridging below the surface, which is hard to correct after it’s soldered down.

So we decided to go back to thru-hole with the finals. We soldered about half of them with thru-hole headers, which, let me tell you, is a pain. 40 header pins soldered to the board, and 40 soldered to the Pico. It’s tried and true, and any screw-ups are obvious and visible, but we were disappointed.

I was assembling the last of batch 1 earlier today, and decided on a whim to try headerless soldering directly to the pads with regular solder instead of paste. I used a 20-pin header temporarily on the left side to hold the pico in place on the board, soldered down the right side, then removed the header and soldered down the left. It worked great. It’s the best of both worlds. It saves wasted time with headers, cuts soldering in half, and keeps unsightly pins from poking out the bottom of the board. Just like regular thru-hole soldering, problems are visible. Bridging is not usually a problem, the solder tends to stick to the pads on the board as well as the generous copper pads on the Pico. All I need to do is make sure there’s a nice ramp from the upper pad, waterfalling over the castellated edges and onto the board pad.

If you ever have the urge to base a PCB around the Pico, consider this option.

Yes, we’re aware you can get the RP2040 chip on its own without the Pico, but one of our members bought a whole REEL of Picos, so it made sense for us to do this.

Hack your Vagus Nerve with the Tree of Life badge

We added guided breathing to our badge. Whether you use it to control your heart rate, raise your kundalini or simply de-stress, that’s up to you. But the badge now includes three levels of guided Vagus breathing. Just follow along with the pretty lights, sync yourself up, and get ready.

I first learned how profoundly breathing can affect the mind and body when I encountered a book in the 80s called Taoist Yoga: Alchemy and Immortality. It’s the kind of thing that has pretty much instant results, and makes you want to come back for more.

I was recently reminded when reading Recapture the Rapture: Rethinking God, Sex and Death in a World that’s Losts its Mind by Jamie Wheal.

I thought I’d bring this to the badgelife folks for consideration and feedback, so we included it in our badge for this year.

And no, the Vegas/Vagus puns are not lost on us at all.

A glimpse of the final boards…

I just realized we’ve been so focused on getting them out on the Twitterverse that we haven’t posted an updated view of the final badges here.

With the green prototypes, we found we couldn’t flow most colors through the substrate perfectly, because all of the “cool” colors were too close to the green solder mask, and basically made large green clouds behind the board. Nice effect, but we wanted more flexibility.

We thought it would work better with black, allowing us to take advantage of the RGBs on the second board, but we weren’t expecting it to look THIS good. Kevin’s working hard on visual effects, and the challenge games, and implementing a Vagus breathing exercise (what happens in vagus stays in vagus) assistant to help you de-stress during and after the con. I don’t think that’s been done on an indie badge before, LOL. There’ll be a separate article on that later. Or you could just google it.

The badge will come with a custom lanyard and a little bit of swag. Hopefully we’ll find time to add an instruction manual. We’ve got the anti-static bags, the shipping boxes, and all the swag. We’re just waiting for the lanyards and the final firmware. We will definitely have some at the con*, but we’ll have more ready to ship within a couple weeks after the con, unless miracles happen and heaven and earth and international shipping bend to our will. Stranger things have happened. Stay tuned. Follow us on twitter @dc540_nova for the latest updates. Join the Discord if you want to hang out with us. We’re usually online Monday evenings, although this Monday we’ll be a bit distracted soldering a bunch of stuff.

[*Assuming the con still happens. From this viewpoint, it appears things are heating up in the west. My plan is to go if I can, i.e., if the con isn’t cancelled, if travel isn’t disrupted, and if restrictions don’t make it impossible. If plans get disrupted, ours or yours, everyone who ordered badges for hand delivery can have them shipped, we’ll figure it out.]

Also, Kevin created a stellar hype video to get your blood pumping (before we slow it down again with the Vagus breathing exercises).

So Close!

Just waiting on lanyards and firmware now. Started acquiring parts for batch , so don’t give up on your FOMO. We’re here for you!

DC540 Badge and Game

While numerous LEDs, an OLED screen, and a stunning design on a completed badge are all commendable achievements in their own right, the DC540 does nothing in moderation. For our first badge, we would not stop there, we wanted to stress ourselves unnecessarily, develop new skills by constantly troubleshooting and redoing processes, test to the max our patience and group dynamic, all in designing a game for the badge.

So, I’m rather excited to announce that the DC540 badge comes with an interactive game that can be played during DEFCON. This game is meant to be a way to enjoy DEFCON while still experiencing the conference. It is a path to make the whole experience more fun for those who are completely new to the scene. This game does not require any serious skills and some challenges are just meant to be a way to get out there and experience Las Vegas, DEFCON, meet fellow hackers, and have a good time.

The game begins Friday, August 6th at 0900 and ends Saturday, August 7th at midnight. We will be around Thursday and throughout the CON for anyone who wants to purchase a badge and play the game.

What To Expect:

The game consists of ten challenges (one for each Sephiroth (sphere) in the Tree of Life). A detailed list of the challenges will be posted on the website early Friday morning (6 AUG). As you solve a challenge, you will receive a code that must be manually input into the badge using the buttons. The code will unlock the challenge which then lights up the corresponding sphere on the badge.

More information on the game will come in the following weeks as we continue to perfect it.
