Retract settings are not the same on all machines. it depends on filamant used and temps, and setup.  there are retraction calibration models on thingiverse you can try. or dial back 1mm on retration and retry.

moodlite Electronics / Re: Questions regarding Amp for power supply
« on: February 22, 2019, 01:18:40 PM »
I keep seeing these crazy amp figures being used,   68 leds with a 2 amp charger is just crazy.  its not just how many leds you are using, but also the distance between each led. some of the palette patterns which include just a few tiles of white, voltage drop can be clearly seen even using an 8 amp power supply.  if cost isnt an issue then go with a 10 amp supply, and when you have completed your build run a second 5v feed to your last tile to reduce the voltage drop. I run mine on 255 full brightness quite often without any issues.

Voltage drop is not good, for either your leds, or your power supply.. Both will get excessively hot, and you will have more chance of your power supply failing.

 i have built hundreds of projects using the ws2812b and never had one fail due to heat being run at full 255 brightness. ( this does depend on the material they are stuck too).  Running some of the palette code in this project which includes the just one or 2 tiles of white voltage drop can be seen, so even though your not running full white, it is still apparent in the other colours too.., just not so visable.

I did a review of this project and had issues, one was volatge drop, the other was a bad esp8266..,   and i show 2 cases of volage drop. this is part 2, in part one i do give full credit to the deisgners of this project.

ey @mannymiller!

I have news! I received the ADMP401 mem microphone module i ordered from china today and ive been playing with it all the afternoon. It works a lot better than the arduino microphone MAX4466. Im looking for some simple code to test it and get some clear animations, right now im using some demo codes from here: but they are a little complex to test them

I saw your moodlight reviews on cine-light! Glad you solved your problems. Now lets see if we can make some sound reaction effects and add them to the project!

Sorry for the late reply.., been very busy.

I have about 18 vu meter patterns which i use for all my vu meters, the problem being is the design., for example, some vu meters just dont look right on a led ring, but look cool on a strip. and visa versa. because this is  made of triangles with 3 leds per corner some vu meter patterns may look strange.  when i get a chance i will throw a video together testing all the vu meters and then people can pick which looks best...  juggle and ripple vu meters will look cool....

I have 21 tiles (63 leds) set at the moment
I measured the power consumption with a kill-a-watt, set the color to full bright white and the draw was 10 watt, thefore ~5v@2A
To me that figure seems way to low.

I am running 10 panels with 9 leds per panel, so 90 leds.  its not so much the ammount of leds used, but the distance betweem them., 10 panels = almost 5.1 metres.

I build alot of projects using the ws2812b leds., some of my matrix use 16x16 leds ( 256 leds.) and i can use a 8 amp power supply without issues., yet on this project it struggled with 90 leds on full white (255), to fix this i did run a second 5v feed to my last panel to cure my voltage drop. ( see previous topic i posted)

i am now using a 10 amp power supply and can obtain full bright white without issue. if you are getting voltage drops, then something somewhere is going to get hot in a very short ammount of time.

The version i was using was from amazon : MakerHawk 2pcs ESP8266 Module ESP8266 ESP-12E Development Board ., looked very much the same as the ones that was recommended.. i used the arduino uno to check the led setup., a strand test etc.. and it worked 100%, so to me it was a data line issue... increasing the data line from 3.3v to 5v did not seem to work.. removed the interupts as that seems to cause an issue sometimes.., but still had the issue.., the original esp8266 that was recommended came back in stock so placed an order for them to see if that was the issue... just on the off chance i tried the esp32 and it worked..,

So it was a board problem.., but the voltage drop out.. it still needs  that second 5v on the last panel to get it right...

which board are you using ? .,.. I am quite new to the esp8266.. always used the uno and ,mega`s and even teensy... never had any issues.  i even purchased the recommended board.., and tried 2 versions of it with still no joy. The esp32 just worked.. no glitches or anything... now off to make a video of my build which i hope will help a few others, and send a few more people this way...

Just wondering.. bit of a long shot but you have added the correct number of LED's, just thinking if it's slightly over then you might get a pause effect.

it wasn`t a pause effect.., sinelon effect during its trail would leave glitches.., just random flashes.  i have used the sinelon and juggle effect in many of my projects ( cine-lights youtube channel ).. so i knew it wasnt a problem with led configuration.. more power or timings...

After running out of options, i decided to order a few more esp8266 boards just incase.. in the mean time i fitted an esp32 board... and who would have guessed, glitching fixed.  im guessing not all boards are  created equal.  seems a little buggy when updating leds count etc.  but works 100%. i still need the extra 5v supply and looks better at 200, instead of 255 ( full brightness )...

Just a quick update.. ,

I have tried the Adafruit 74AHCT125 - Quad Level-Shifter (3V to 5V) [ADA1787] and this made no difference whats so ever with the glitching when running sinelon and some of the other animations. 
I also tried the diode hack as suggested and this made very little, if any difference.  The voltage drop im using a 10amp power supply, running an extra 5v lead to the last panel, with this i can run 255 bright white without issues. 10 amps for 90 leds is just plain crazy... I have recently built a 30x8 ws2812b led matrix ( 240 leds ) for one of my projects, using the same esp8266 board and it has no problems with using a 8 amp power supply... no glitching or voltage drop., so guessing its down to the distance between the leds.. The total distance over 10 panels is 5.1 metres, if your getting voltage drop out even with a 10 amp power supply, im guessing your going to get voltage drop out on the signal wire too....

Im tempted as this time to lose the esp8266 and throw in an arduino nano with a few patterns i would use, and add bluetooth support.

I removed the esp8266 and installed an arduino uno in its place and ran a few tests.

The power drop out is still apparent from 36 leds onwards. leds 36 to 45 drop by about 10% and  each panel after drops about 5%. brightness on each panel after.. adding a second 5v on the last panel (81 -90) fixes most of the issue. but there is still a visable drop of about 5%.. reducing to white from full brightness (255) to 200 its even across each panel without any noticeable drop.

running the fasted led examples, sinelone, juggle, bpm etc on full brightness (255), there zero problems, no glitching or flickering - runs very smooth.

so im sure the level shifter will help with any flickering glitching issues. some may see less depending on brand of leds.  As for obtaining a near full bright white then the only way this can be obtained is running a second 5v feed to your last panel. this was tested using a 4 amp, 5amp, and 8 amp supply with the same results

if like me you have made each panel the same, you should have a spare socket on your last panel. adding a second 5v wire from the power supply and plugging into the last socket works quite well.

Hey spigot, i have never used a capacitor in any of my projects and never had a problem,  but then it doesnt mean something can go wrong.

personally i have ordered the :    Adafruit 74AHCT125 - Quad Level-Shifter (3V to 5V) [ADA1787]  from amazon.., about 3
and also : 8-channel Bi-directional Logic Level Shifter Converter Module  from ebay, about 2.50

amazon arriving sooner., but is the bare chip, which is pretty easy to connect up., my other option is.. as all the panels will be connected in a set position ( mine will be stuck to a panel ) i will run a second 5v feed to the end of the chain.

but before i jump in, i will connect up an arduino and run a few tests to  make sure it isnt any other issue. it will be using the same 5v supply etc, so the only difference will be the data feed.

In most of my projects i have always used the Arduino,  some of my projects include a 14x14, and 16x16 matrix, so 249 leds on the later. i usually add a second 5v power to led 249 ( end of strip ) and never have any issues with power drop outs.  my stereo vu meters use 72 leds per channel - so 144 leds total and do not bother with the second 5v source, and again do not have any issues. ( my setup at the moment is 90 leds)

Adding the second 5v to this setup certainly helps, but doesnt fix the issue 100% thats why i leaning towards increasing the signal wire from 3.3v to 5v using a level shifter.  I dont think its just down to how many leds you are using, but the distance between each led is a factor to.   i found one on ebay for quite cheap. this would also help with some of the issues people are having with flickering.

As you have mentioned on normal rainbow effects its fine, but when using some of the faster patterns i seem to get a random flicker too..

i will report back once i have fitted it which will be a while as its coming from china...

Hey everyone..., 

I finally completed my setup which seems to be working quite well. my issue is power drop out. if i select full white, full brightness i get a power drop around panel 6 ( 3 leds per corner) so 59 leds onwards. if i add another 5v power source at panel 10 its not perfect, but 95% fixed. anyone else having this issue ?or could you try and see if you also get the problem.  i am using a 4amp power supply, which i have used on many of my other projects without issue. and just to dis-prove a power supply issue i used an 8amp powersupply which powers a 64x64 led matrix and the issue is still apparent.

maybe a fix ? :

Hey shiryou, its not that sinelon and juggle do not work,  but more they do not suit this build.  im guessing its down to personal taste., i do prefer a nice slow animation on this particular setup. if you have seen my vu meters,  sinelon and juggle work quite well, but on the ring version those patterns don`t .. its just down to taste i guess..

i have used the msgeq7 board for a few of my setups, its a capable board and produces great sound reaction.  To make it easier for people to build that particular vu meter i recommend the msgeq7 board, the downside is cost and the only decent one i can find is in the US..  i can get a 5 metre, 60 leds a metre led strip for 19, the msgeq7 board is 12 for mono, or 15 for stereo add 5 shipping.. it just doesnt make sense.   i printed 10 pieces out of a roll of filament ( 13),   The leds using 3 a corner worked out about a metre and a half ( 7),  2 x esp8266 (8) , then a msgeq7 breakout board (19 with shipping) ...

 yes i could build one of my own, then you have problems with fake chips ( which is quite common)  then you have problems with other people building them.  Like you i share what i do for free,  i do not make any money out of it as its a hobby i enjoy. so i try and make things a simple as possible so i do not spend what little time i have helping people with there problems.., if that makes sense.

 My llne in version uses a couple of resistors and a capacitor and works as well as the msgeq7 for sound reaction.  but as mentioned a rather long input lead would be needed.  A wireless version using the esp8266 has been done  seen here :
&t=259s not sure if something like this could be added to this setup.

Anyways, just ideas... But so far what has been done is brilliant. i finished converting from 1 led a corner to 3 this afternoon and hope to get a video together which will be a review of my build. hopefully it will push some more people your way.. keep up the great work!!!

Hey.. i fixed my issue by clearing EEPROM, as well as  SPIFFS.. problem fixed.  as for Allstars issue i havent encountered it yet.  having worked with the ws2812b leds, see here at Cine-lights, on my youtube channel

my channel... i have used bluetooth and IRRemote before and the ws2812b do not like them.  they do not like interupts, even little ones.  i have tried the command #define FASTLED_INTERRUPT_RETRY_COUNT   0 or otherwise on my fasteled fire examples and found it reduced the framerate to almost a standstill.. so removed it from all of my shared code. So Allstar it maybe worth trying,  comment out that line to see if it helps.

I have changed my setup from a single led a corner to 3 a corner to try and get closer to the original nano leaf. , i will be sharing my build etc on my channel, as well as all links to here, and obviously all credit to you guys.. here would be a little advice.., The added palettes in version 2.0 is a great add..,  but some patterns do not work on this project. sinelon, juggle etc..  ripple would, but slowed down. As for sound reactive, ( As seen from my youtube channel)  its what i have spent alot of time covering do not use a microphone..,  aim for line in. yes its a long arse cable.. or you could add a second esp8266 to send the data .. an idea.!!???  as i do intend of adding wifi / wireless to my vu meters..

keep up the good work..
