Ok, so I like electronic dance music, more specifically Trance. When I started in the 1990's, the US was a bit behind in that department.
Still, with San Francisco and San Jose nearby, I've had some opportunities to see some great EDM/Trance DJs. Back in the early 2000's, they sadly played club music in the US that was nowhere close to the hits they had composed and were known for, but over the years, as Trance started becoming more popular, those DJs finally started playing their good tunes in the US too, and maybe from 2004 on, it's only been getting better. Popsicle Halloween 2004> was really the beginning of great music parties in the San Francisco Area, and thankfully things have gotten even better since then
As a matter of fact, after another 10 years (2015 and beyond) the good news is that Trance has grown quite a following in the US, and places like the SF Bay Area, and while Trance has been declared dead a few times in the last 10 years, it's still going strong here.
Trance Family SF is definitely strong in the area, we've been getting more big trance parties every year, including many top DJs that come visit us what feels like every other week now (as of 2018-2019), and through those events, I made many friends in Trance Family SF. Thanks to you all.
Over those years, I got the chance to meet a few of my favourite DJs, including Armin more than once, and my last hobby has been to work on lights for my shirt and pants (version 3) and (version 4)
I'll admit that I didn't know Allen Watts, which was on me. I should have known him, and now I do :)
Eugene Luu opened for the first 2 hours with a good set. We enjoyed it:
Allen Watts took over at 23:00 for a 3H set, which was really good. It was 3 hours of goodness, and I'm very happy I got to learn about a DJ I didn't know yet and plays Trance I quite enjoy. Thank you to the folks who organized the event and got him over:
I really enjoyed what he played, here's a quick summary:
IT had been a while since I saw Orjan. He's a solid trance DJ I had seen in a festival at shoreline years back, and hadn't seen since then. It was great to see that he was visiting SF, even if it happened to be on a thursday night. So, I decided to go.
AudioSF, however, continued its trend of not bothering to post any set times, or even who the opening DJ was going to be, because I guess it's not important for them to tell us?
Sadly, the opening DJ, was... well, I try not to say bad things about DJs in general, because even if they're not great or I happen not to enjoy the music they're playing, they're still DJs, and I'm not, so that's probably enough of a reason that I can STFU :)
But I'll say at least that AudioSF needs to get a clue and use opening DJs that remotely play the same genre than the same DJ.
Poor Orjan had to work hard to bring the room back to Trance, which in theory was supposed to be the point of that night. Thankfully he did, and good time was had after that.
he was super nice and posed for a lot of pictures that night. Thanks Orjan
After months and months of work, here is version 4:
Sadly, going up in resolution with addressable pixels, is not that easy. While in theory you should be able to fit at least 2 addressable pixels per centimeter (aka P5). Currently my premade panels are P10, which is the only thing I could buy pre-made.
What allowed me to switch were those flexible P4 RGB Panels from Azerone: https://amazon.com/gp/product/B07F87CM6Y
With their P4 resolution, I'm able to fit 96x64 on my body using 3 panels of 64x32 chained together. The 3rd panel is then chained to the 2nd set of 3 panels in my back:
On the old shirt, I put the rear panel inside the shirt, using the shirt as a diffuser, but with the RBGPanels, they were too thick for this to be practical, so I had to put them on top of the shirt. As a result, I ended up uing a black shirt which matches the color of the panels. I had to attach velcro to the new shirt, and confirmed that supergluing them was so much faster than sawing, and worked just as well:
I unsoldered the power connectors that were too thick, and used small metal wire to connect the panels together (see top middle of the picture). Turned out those metal wires were a mistake as they can cause shorts on the LEDs on the other side of the board:
Another thing I learned was that the holes I was using to put a metal wire to carry the panels over my shoulders, can't actually take the load, and the wire can cause damage to the copper trace that is just next to the hole. As a result, I replaced the metal wires with fishing wire and didn't use the bigger holes for load bearing:
Speaking of removing thickness from the board, I removed the top of the ribbon connectors to make them a bit thinner. Sadly, RGBPanels still require 15 wires to send the video signal:
I then took one panel and covered it with defusing foam (the rear panel, so that it's not too sharp and blinding to people behind me), while the front panel only has the plastic cover to protect the panels and offer a bit of extra diffusion:
you can see the difference between the diffusion levels
I then protected the rear of the panels given how much electronics were exposed:
Small details had to be solved, like making sure I had enough amps going through the wires (use thicker wires). Without that, my brightest pattern that uses 8 amps, didn't quite make it:
For fun, I made a pattern that scrolls my C++ scrolling code on the screens:
I went from a breadboard prototype to Jason Coon's ESP32 level shifter board, much more tidy
This video shows how things are wired from the ESP32 to the panels:
Here is what the whole power system looks like:
2 4S Lipos, 5Ah, 80wh, giving a total 160Wh of energy
Amp meter in line with the lipos and cell tester with low voltage warning buzzer
Amp gauge with timer to know how much energy flowed from the batteries (you can't run lipos down or they'll die)
Tobsun DC-DC converter to take voltage down to 5V
2nd voltage regulator to bring the voltage further down to 3.3V for the El Wire glasses
5V goes to RGBPanels via separate thick wire to carry the amps
ESP32 with level shifters from 3.3V back up to 5V for the RGBPanels (6 channels for the colors to level shifters, 4 address lines to do 16 scan line refreshes). CPU runs SmartMatrix::GFX and NeoMatrix-FastLED-IR
16th data line is used for the Neopixel strips on my arms and legs, running the same code than the previous shirt
Here is an example of 3 levels of diffusers, including a raw set of panels with no diffusers:
You can see a demo of the outfit being worn:
If you don't have time for all this, and are ok with 64x64, you can try this backpack from gearbest with everything built in and a very thin board. Just not fun for me because I can't run my own code on it:
I can't believe it had been 15 years since I last saw Paul Oakenfold in a club, namely Ruby Skye, and funny thing enough the last 3 times I saw him after that were at Burning Man (2005, 2007, and 2014).
Paul has alwasy been special to me, because he was the first Trance DJ I started listening to in the late 90's. I had 3 of his albums on loop in my not so portable battery powered hard drive archos MP3 player :)
Sadly, he's falling a bit out of favour over the years, but then again it's been 25 years. It's hard to stay at the top for so long. At the same time, I can understand it must be hard for him to go back from big arenas to smaller clubs (and to be fair Audio SF was a disappoitingly small club). On the plus side, many of the people who showed up were likely his true fans from over the years, so hopefully that was heartwarming for him.
Chris Willscape opened the evening:
Around midnight, Oakey took over for what was supposed to be a 2.5H set.
The first hour of the set was so so, and a slow transition from the previous DJ who was not playing uninspiring music, and then he transitioned into nice trance. Honestly, he didn't seem to have much of a good time initially (he was probably also a bit tired as he made a few DJ mistakes during his set like a very poor off beat transiton, or even playing the same tune twice by mistake), but he eventually warmed up and started playing more nice tunes.
In the end, the set turned into almost 3.5H because we were all having a good time :)
By 03:30, the club had thinned out a lot given that it was late, but his true fans were still there, and he was nice enough to stay for pictures, which was the best news of the night for me, a picture with my first EDM DJ, the one who brought me into this rabbit hole:
Thanks Paul, thanks for the night and all the years before that.
It's been almost a year since TFSF8 for which I had built my matrix shirt.
It was time to try my new beta shirt with 6144 pixels instead of 768 pixels per side. That was a lot more work (months of work to get a new driver working and port my code). It's not perfect yet, but it's a good start.
This was last year, Shirt v3:
And this year with my Shirt v4:
If you are curious, this page that shows how I built my EDM Festival and Burning Man LED Pants and Shirt v4 on ESP32 with RGBPanels and SmartMatrix::GFX.
Back to TFSF9, this year was only 2 rooms/DJs compared to the 4 rooms/DJs in TFSF7 and TFSF8 these last 2 years. There is a case to less is more, too many rooms makes it hard to enjoy much of anything, knowing that you're missing 3 other sets at the same time, but maybe 3 rooms would have been better, or at least using one of the indoors rooms instead of the somewhat chilly outside psytrance patio?
Anyway, I was there bright and early with my friend Triode to make sure I could enjoy the entire night, and got a few pictures during setup;
Kim checking out the VIP menu
The 2 stages started going soon after 20:00 and the main room was more enjoyable than last year where it was overrun with smoke and a bit too packed at times:
Then, soon after 23:00, my I went to check out Triode's custom set he had been working on and telling me about during the week. As we jokingly said, I dedicated it as the "zero fucks given" set :) It was fun to see how it went all over and jumped from tune to tune just enough to tease you and then go in another direction. Quite fun and enjoyable:
After Triode, I went back to the main room for Ferry Corsten who went from midnight to 03:00.
In between, I went arond the rooms to mingle with the crowds and catch up with some friends:
Triode and Afik talking shop
And before long, it was 04:00, end of the evening. Thanks all for the great vibes and the music. See you next time!
Quick, very incomplete video summary:
After a long wait, ATB finally showed up at 00:30. Despite being close to the front, it was hard to take pictures due to lack of lighting and some bad apples in the crowd that were pushing and shoving to try and get closer. 2 out of control girls kept pushing violently and managed to damage my shirt. Too bad security guys were completely unreachable on that side of the room without losing the spot I had spent hours to get...
ATB's set, while on the short side (just 90mn), was good. I did my best to enjoy it despite the crowd and shoving issues that Mezzanine was unable to see or address:
After his set, he nicely came to shake people's hands, which is obviously not something you get at a big festival where you'd usually see him:
