Title: Spigot's Build Log
Post by: spigot on January 06, 2019, 02:53:08 PM
While I'm waiting for my Servo Extention leads, I was finally able to put 3 tiles together for testing purposes.

I have 3 LEDs per corner.

I also made a small "PCB" with extra micro USB port for ESP + LEDs powering. ESP USB port will be used only for uploading sketches. Instead of NodeMCU I'm using Wemos D1 mini.

Looks nice! Can't wait to get my stuff to build my Moodlite.

Should we do a version of the power block that allows to lead the controllers USB port to the outside by using an extension cable?

Somehting like this:

I did the PCB because:
1. Resistor
2. Capacitor
3. It's not recommended to power LEDs from Arduino. It's safe for few LEDs, but more LEDs more problems (same as capacitor, etc.)

I would like to create power cover for my PCB (with 2 holes for micro USB connectors). But don't how how fast I'm able to do it.  :( Or maybe someone else would do it.  ;)

Will you do a diagram for that PCB so that we can follow that?

Maybe can do a modified power cover. I'm on the power cover for the larger NodeMCU anyways.

Ok. Tomorow I'll make wiring diagram in fritzing and BOM.

Definitely interested in both the power box with USB access as well as the resistor and capacitor details.  Hopefully we can smash all that stuff into the power box.

FYI:  Found this site which has some details on the wiring:

Wiring sketch.

In this sketch I already have a HW button to make reset (it's not implemented yet in v1.1.2).

Capacitor: 1000uF
LED resistor: 470 Ohm
Button resistor: 10kOhm
Micro Usb - B

And the PCB.
Title: Re: Spigot's Build Log
Post by: LordVader on January 07, 2019, 04:38:38 PM
Thanks!

What will the reset button do what the reset button on the board can't do? "Factory" reset?

And what about the USB port on your sketch? Can this be used for flashing although the power supply is connected?
What part did you use for that? I'd like to modify the power block model so that we can mount this USB port properly.
Title: Re: Spigot's Build Log
Post by: spigot on January 07, 2019, 04:43:05 PM
The reset buton is for "factory reset" -> EEPROM reset

The USB port on my sketch is under the PCB (from other side). It's only for powering the ESP and LEDs. For flashing I always use Arduinos USB port.

Title: Re: Spigot's Build Log
Post by: LordVader on January 07, 2019, 05:04:57 PM
Thanks for the explanation.

So when powering the system via USB completely, we really should modify the power block for fitting a USB socket.
Really like that! :D
Title: Re: Spigot's Build Log
Post by: spigot on January 07, 2019, 05:53:28 PM
We only need 2 holes in the wall for 2 USB ports. Just like on any device with micro USB port.
Title: Re: Spigot's Build Log
Post by: LordVader on January 07, 2019, 07:01:34 PM
Does the WEMO fit into the power brick with the USB port facing downwards?
Otherwise we'll need to make more space or use these USB extensions with mounting.
Title: Re: Spigot's Build Log
Post by: spigot on January 07, 2019, 07:30:09 PM
Sorry, but I don't know. I had no time to print the power brick. I'll try tomorrow and let you know. Thanks.

I've added some more space to fit the Wemos.

(https://abload.de/img/2019-01-0813_11_02-wizueim.png)

Could you give me the distance between both USB ports (ideally measured from their center)? Then I could move the terminals to the correct place.

Wow! Now that's an impressing drawing :D

I've modified my CAD according to your measuring. I assume that this is working although your USB ports aren't at the same height.
In case you need something to raise the whole PCB, give me a shout.

I can't do a test print to look if everything fits as the PSU of my printer died yesterday :(
So feel free to do so or wait till my printer is up and running again by the end of the week.

Thank you LordVader
I think I need to add some frame to keep the PCB in place

Post by: LordVader on January 09, 2019, 08:25:04 PM
Sure, why not.
Can you measure these distances?
(https://i.imgur.com/HYpywqR.png)

And are you able to move the capacitor next to the pcb? Otherwise we would need to make the case much thicker to achieve more clearance for it.
Furthermore I could then add a little platform for the whole PCB so that the right USB port is better reachable.

Post by: spigot on January 09, 2019, 08:55:43 PM
Thanks.

I can move the capacitor next to PCB (it won't be very nice, but why not). I would also remove the part under USB ports, to get ports closer to the wall?
Title: Re: Spigot's Build Log
Post by: LordVader on January 10, 2019, 11:17:06 AM
That's what I've done now. I'm not really happy with this as this doesn't completely prevent the PCB from moving around in the case.
Do you think that you can use one of the PCB's holes to screw a tiny screw into the case? I would then add a pole similar to the one for the microphone but smaller.

Post by: LordVader on January 10, 2019, 11:54:44 AM
Just got a better idea. This will need some time for CAD'ing.
Coming back later :D
Title: Re: Spigot's Build Log
Post by: spigot on January 10, 2019, 12:16:20 PM
Thank you. I hope it's not too much trouble  ;)

One more idea ;D ;D
If the USB ports will be closer to the wall. The round holes could have square shape (maybe a little bit bigger / few mm,  than the USB port itself)?  Than the wall could have the same height around whole power block.
Does it make sense to you?  ???
Title: Re: Spigot's Build Log
Post by: LordVader on January 10, 2019, 02:12:43 PM
Looking at the USB cable you are using I can see, that making the hole smaller would lead to making some USB cables not work anymore, unless we make the outer wall really thin.
I think that we can stick with the momentary solution if it's not bothering you. Or do you want to make the power block thinner to achieve a better look?
Title: Re: Spigot's Build Log

Final stage.

Do you find having 3 leds per corner brighter? Seems the LED's I got don't get anywhere near as bright as the nanos.
Title: Re: Spigot's Build Log
Post by: spigot on February 01, 2019, 02:11:19 PM
I find it quite bright.  :D I'm using it with brightness between 10 and 20, not more. I like it that way.

Hi Spigot,

great build, I love the idea of 3 leds per corner.
What kind of power supply are you currently using to power all 15 panels?

I am currently using the ws2812b leds which in theory use 60 mA per led at maximum.
So the maximum power for 15 panels = 15 x 9 leds (per panel) = 135 leds, which in total use 8.1A at max.
Or are you using multiple power supplies/adapters?

Thanks in advance,

Gotchar

Post by: spigot on February 08, 2019, 02:52:55 PM
Hi Gotchar.

   I'm using power supply from Motorola

(https://i.imgur.com/8u0aIIs.jpg)

The 8.1A would by white (all 3 LEDs On) at maximum brightness, but I don't use that way.

I have these parameters:
Brightness: 10-20
Colors: Rainbow
Pattern: Standard

And there's no problem with power.

Can you give us your .stl file with the two holes. Have you split your cable and use 2 micro usb cables or have you a diffent power supply for each micro usb port?

I'm using only one power supply connected to the micro board. The Wemos D1 and LEDs are powered from this micro board.

The Wemos D1 micro usb is used only for direct connection from my computer.

First check +5V, GND on both sides (USB and Arduino).
