2019/05/26 Trance Family SF Party v2 at 1015
π 2019-05-26 01:01 in Clubbing
TFSF returned to 1015 for a 4 room set. It was 5H in 4 rooms, difficult to see it all, but we did our best (Jennifer was able to join me).

Here's close to 1H from my roving camera: https://www.youtube.com/watch?v=6D4Db10AfJo



























And here is close to 1H of DJ Blurr's set in the classics' room:

Here's another 30mn+ from the front room with Alastair James B2B Voices From Within:

2019/05/26 FastLED_SPITFT::GFX on top of Framebuffer::GFX for SPI TFTs like SSD1331 or ILI9341
π 2019-05-26 01:01 in Arduino
Show me the code! Sure:
  • https://github.com/marcmerlin/FastLED_SPITFT_GFX (SSD1331, ST7735, or ILI9341 on top of FastLED CRGB 2D Matrix)
  • https://github.com/marcmerlin/Framebuffer_GFX
  • Framebuffer::GFX

    After writing my 3rd backend glue driver (SSD1331 SPI TFTs) that supports Adafruit::GFX, FastLED CRGB's primitives (nblend, dim, etc...) and matrix mapping via XY() function, and LEDMatrix which is another GFX like API on top of FastLED, I realized that I had to factor that out into a new base class I called Framebuffer::GFX:
    https://github.com/marcmerlin/Framebuffer_GFX

    That new base class takes all the GFX glue and color support I mixed (GFX RGB565, FastLED CRGB structs (RGB888 24bit), and uint32_t backed 24bit RGB888 colors, and creates a virtual framebuffer compatible with FastLED and SmartMatrix (which thankfully can use the same 3 byte per pixel array type).
    Framebuffer::GFX in itself is only a framebuffer storage and method holder, but it contains so much common code that my 3 drivers that use it are only a few dozen lines of code after inheriting from it.

    Here is the list of drivers I've written against Framebuffer::GFX:

  • https://github.com/marcmerlin/FastLED_NeoMatrix
  • https://github.com/marcmerlin/SmartMatrix_GFX
  • https://github.com/marcmerlin/FastLED_SPITFT_GFX (SSD1331 and ILI9341 TFTs)
  • Here is an example of code ultimately running on top of Framebuffer::GFX with FastLED::NeoMatrix on ESP8266 (24x32 and 32x32) and SmartMatrix::GFX on ESP32 (64x96):


    Below is the same code again now running on top of FastLED_SPITFT::GFX on an SSD1331 96x64 TFT screen:


    FastLED_SPITFT::GFX

    SSD1331

    FastLED_SPITFT_GFX, the last driver I wrote, takes any Adafruit SPI TFT object (like SSD1331 and ILI9341), and a FastLED CRGB array. You then tell it the size of each (it's up to you not to make mistakes or you can create buffer overruns), and the overloaded show() method will send the framebuffer to the TFT (it is done line by line with an SPI copy method):
  • FastLED_SPITFT_GFX(fb, 96, 64, 96, 64, ssd1331, 0) for unrotated
  • FastLED_SPITFT_GFX(fb, 64, 96, 96, 64, ssd1331, 1) for a 90 degree rotation
  • Here is the end result, an ESP8266 running LEDMatrix code rendered in Framebuffer_GFX, downsampled from 24bit color to 16bit color, rotated and copied line by line to a SSD1331



    Here is a video of Jason Coon's Aurora in 64x96 rotated to the SSD1331 96x64 resolution:

    It's ironic that normally Neopixel matrices look like they have huge pixels compared to RGBPanes, but here my 64x96 RGBPanel looks huge compared to the same resolution on SSD1331:

    Table from Mark Estes Video Demo:

    ST7735 or ILI9341

    Thankfully Adafruit wrote other TFT drivers like ST7735 and ILI9341 against the same Adafruit_SPITFT object from Adafruit-GFX, so I was able to target that tft object in FastLED_SPITFT::GFX and get the same code to work with other TFTs without any modifications.

    As a result, all you need to do is to pass the different tft object, display size, and everything else works.

    Adafruit_ILI9341 *tft = new Adafruit_ILI9341(TFT_CS, TFT_DC, TFT_RST);
    or
    Adafruit_ST7735 *tft = new Adafruit_ST7735(TFT_CS, TFT_DC, TFT_RST);
    FastLED_SPITFT_GFX *matrix = new FastLED_SPITFT_GFX(matrixleds, mw, mh, mw, mh, tft, 0);

    For comparison, SSD1331 vs ST7735 128x128, ST7735 128x160 from 2 different vendors and slightly different chips, and ILI9341 with a full 320x240 which stretches the limit of this library since it requires 225KB for that many pixels and that only fits on a teensy 3.5/3.6:

    the SSD1331 screen is off as it's not compatible and requires different code to turn on

    ST7735R vs ST7735S chip revisions show a few differences
    ST7735R vs ST7735S chip revisions show a few differences

    code for the 128x128 ST7735 doesn't mis-display the same on the two 128x160 displays

    Some demos showing 128x128 and 128x160 on multiple size screens (for physical size comparison):

    Hopefully this is useful to you and by using the FastLED_SPITFT::GFX API, you can re-use your code on TFTs, FastLED::NeoMatrix and SmartMatrix::GFX.

    2019/05/21 Brian Cox at SF's SHN Orpheum Theatre
    π 2019-05-21 01:01 in Public
    I've also been a fan of Brian Cox since watching his many BBC shows on the universe and kind of chuckled at his last one where he got the BBC to pay for nice vacations around the world and tie it back in a universe show anyway :)

    When I heard he was coming to San Francisco, I figured it would be fun to go see him. Contrary to Neil deGrasse Tyson at San Jose Center for Performing Arts, his talk was a bit more technical, and explained the concept of spacetime in a way that most people could grasp.

    However, about half the talk was also more metaphysical, mostly with his sidekick (whom I didn't know), Robin Ince, who I just found out, is actually a comedian. I wasn't as much of a fan of his part which I thought detracted of other things Brian could have shared with us.

    That being said, it was still a good evening, happy to have gone to see him with Jennifer:












    2019/05/17 My 5th EDC (Electric Daisy Carnival) in Vegas
    π 2019-05-17 01:01 in Clubbing
    Can't believe it's been 5 years since my first EDC already, time flies.
    Having learned from previous years (both EDC with the bus system, and me), I left vegas earlier (17:30 to 17:45 all 3 days), which meant not bus line, and that was great.




    The shortcut through the air force base was not always faster depending on traffic to get there, but was a mostly reliable 1-1.5H trip:

    2019/05/17 A little time in Vegas during EDC
    π 2019-05-17 01:01 in Trips
    This was my 5th year going to EDC, which includes time in Vegas of course. This year, I really didn't spend that much time in Vegas given the crazy lineup EDC had. I left around 17:30 each day and came back in the wee hours of the morning and sleep until early afternoon.

    Still, I made it a point to go see a few things one day I got up a bit earlier than planned.

    Jennifer reminded us of the yearly silicon valley open studio weekend, which is a nice way to see all kinds of art around the area, so we did point to point biking to check them out, which was nice both for going around the neighborhood, and checking places out.

    Some of the locations were schools with art teachers, others were art studios, and others still were private residences:

    A mere week from EDC, Anjunabeats came to San Francisco for the end of their tour.

    Another day at Midway SF, this time with two rooms:




    I only had enough energy for one day, and the first day was the best, with the following DJs in the main room:

  • Tinlicker
  • Grum
  • ALPHA 9 b2b Jason Ross
  • Andrew Bayer b2b Ilan Bluestone
  • Side room:

    2019/05/07 BBR Private Track Day at Thunderhill
    π 2019-05-07 01:01 in Cars
    A mere 6 days after Droid and Friends at Thunderhill, I was back for more with BBR and a small group.

    The other folks had already chartered a flight from Moffett, and given that I was tired and the weather was marginal VFR, I happily joined them:




    We had a handful of cars, which meant mostly clear track and little passing for me, leaving me to focus on improving my skills. Despite the day not being very warm, the track felt sticky and I didn't get that fast (I think I got as low as 1:51 (with bypass) after installing fresh tires). Still, I got to work on my technique, so it wasn't all for naught :)




    On the flight back, the pilot did a quick pass by TH, which I hadn't done myself in a while:





    Here's a single session until I spun:

    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:

    2019/05/01 Droid and Friends, Thunderhill 5 miles
    π 2019-05-01 01:01 in Cars
    Another year, another set of trackdays, starting with Droid and Friends. I wasn't in the best condition that day sadly, so I tried but overall I was tired and distracted. That said, Chris, my guest for the day, didn't seem to mind, and had a good time anyway when we went for a ride:



    I only got down to a meager 3:16 with fresh tires, which was 3sec slower than my previous best time, but I guess that's all I was capable of that day, so I didn't try to push too hard and just enjoyed the day the best I could. Despite those challenges, it was still fun to be back to thunderhill and see my friends there.

    A few pictures:
