  • Effect to manually set capture ON

    Hello,
    i use the newest hyperion ng
    i would like to start capture manually from remote using hyperion on android smartphone
    please can you provide me an effect file for this ?


    also maybe something missing is to have possibility to set timer when led can be activated, for example : the morning from 6h to 7h and evening from 19h to 23h


    anyway the grow up is awesome, started with ambibox on windows few years ago.

  • how to install hyperion.ng on raspberry pi 3b+ with libreelc and adalight


    perfect thank you.

  • Level Shifter based MOS

    yep !
    4x +5v / GND ( directly from PSU)
    1X +5V/GND/data/clock ( from PSU and RPi )


    And forgotten i have an wire behind the TV who make an loop of the gnd.for connect the last led to the first. for reduce the drop on ground and bypass the gnd on strip for the dataline.


    but for now, my best result is mosfet level shifter.

  • Level Shifter based MOS

    hello,
    yep 15Ais the total current, but i have 4 wires who link the PSU to leds . so we can sayeach channel can take 3.97A at full brightness.
    Voltage drop: 0.83
    Voltage drop percentage: 16.60%
    Voltage at the end: 4.17


    http://www.calculator.net/volt…rs&amperes=3.97&x=93&y=10


    i will try to use the data wire for connect the +5v on psu too !
    for reduce the number of led on it.


    but the best will be to have 16AWG instead of 18. :mad:
    with my calculator the dropvoltage was good on 18 AWG, but you own not

  • Level Shifter based MOS

    on my sketch you can see 4 wires, the max drop should be 0.38v with Full brightness, with my own calculator.
    but maybe my choice is bad, or my soldering is bad too, wasn't easy to solder 18awg on the strip.

    hello guy's,


    i have used the 74HCT00 as alternative, i have too much flickring compared to Mosfet level shifter.
    so for me, ac my actual stage, the mosfet is less sensible than the nand gate.


    but i always have sometime "flash" on few leds randomly , i think the issue come with my PSU, but is not so bad, it 's an Meanwell RSP75-5.
    i know my wires lenght are very long ( 5meter ) between the Pi and the 1st led, but the wire gauge is an 18AWG. i reduced the number of flickering by adding an extra wire between levelshifter and PSU (60 cm 20 AWG), but always few "flash"
    do you think i can connect the +5v of the PI on level shifter ? instead of the PSU, and make an common GND on return ?


    i will try to make an scheme board, but what software of websoftware do you use for create good draw ?

  • Level Shifter based MOS

    Hello, i think found my culprit
    the delay come from MediaPoral with MadVR enabled
    watching movie and TV with EVR, the delay is better (the led has few ms of delay on the rgb sequence test )
    only need to improve my setup ( lan ... )


    About the levelshifter, except few randomn lightning it seems working great on APA102 ( need to investigate this point)
    i must power on directly from PSU, because i will try to use an extension wire, for store the RPi inside my tv stand
    need to try the 74HCT00
    do you have an method for comparing both result ?

  • Level Shifter based MOS

    Hello guy's
    i have connected all my system to RPi + level shifter ( MOS-fet)


    for now the setup is :
    265 led APA102
    wired with 18AWG ( power + data ) + Power connector on each corner ( 4x0.75mm²)
    PSU : RSP-75-5 (15A - 5 V)
    RPi3 : OSMC + Hyperion ( Network LAN )
    HTPC : MediaPortal (using Atmolight)
    Connection to LED : RPi - SPI


    for now, it seems work with my actual level shifter, i can see few flickering on the green and the blue color.
    i have buy an 74HCT00, i must try with it on test breadboard, if better or not.


    i can try with an arduino too, and an proper sketch.


    except the flickering, i have an delay on the leds display. my TV show the color before the leds. between 1-2 sec.
    on the RGB sequence test video, it's an big joke. :sickxx:
    it's maybe an good solution to open a new thread for this issue.


    @Rick164, i'm here ;)

    thanks,
    i received today my rpi3
    installed OSMC, and wait like an younger, to be back to home for connecting led and try.
    i'm only surprised, than Hypercon download osmc build for RPi2 instead of RPi3.

  • Level Shifter based MOS

    I have read on few thread, than the 74HCT00 is not the best version for use it as level shifter. Due to low voltage of the rpi, the version 74HC00 without the T should be an better choice. What do you think?

    Hello,


    i'm Azzuro, i'm new in the hyperion community.
    i'm in the elaborating since a while now, to create my own ambilight project ( at least more complex)
    i started with WS2801 bull led, and an Arduino (teensy2 board) using AtmoWin and MediaPortal.


    i decided to jump on RPi with APA102 (265 led).


    reading carrefully your wiki, i see than using an RPi for leds, it's better to includ an level shifter.
    i buy an small level shifter board ready to use, found on ebay.


    can you say me , if it's an good solution and i can go with this ?


    the model :

    Description:
    Four MOS tube : four channel , two-way conversation 3V and 5V
    The power input with anti-reverse protection, integrated 3.3VLDO,and provide current less than 150mA
    With power indicate
    Used for UART/IIC/1-WIRE/SPI
