Thanks for the info - coding isn't something I know about really so might see if my lad knows any more about it
Make one insteadWow these are all great shots being shared! Looks like I will need to purchase this new toy soon
But how about doing the super Mario type effect?Make one instead
I wouldn't know where to start on something like this! Stunning photography.
I'm using the elastic - same as the tutorial - it works but could be better and am on the lookout for something better
@rpsmith79 - I got hold of some acrylic from Southern Acrylics (http://southernacrylics.co.uk/) and they were about the only ones who could cut a strip 20mm wide - all the others were 50mm minimum - cost me £25 posted
They sent me two strips 20x1200mm, 1 strip frosted clear and the other frosted white. The frosted clear is too clear in my opinion and the frosted white seems just about right. I've wedged it in to my frame and stuck it down with clear silicon sealer - looks ok to be fair
I've also got hold of some black vinyl wrap and used that at the ends to ensure the strip cannot fall out - the good thing about vinyl wrap is when you heat it with a hair dryer, it goes really pliable and the glue melts and sticks better.
So, all in all, a little tidying of edges etc and its now good to go.
One thing I did notice is when you use a really bright image with low batteries it tends to crash - I think that's just the LED strip drawing too much power and not leaving enough to supply the Arduino - trying high power rechargeables now.
The script otherwise seems stable and much more user friendly
Thanks

First picture with the DIY lightstick, working fine running the fastLED sketch and most of the demos. Still having problems getting it draw any pictures and can't get the potentiometer and trigger to work yet but still learning about the Arduino and electronics in general

Nice, very abstract, have you not fitted a diffuser yet, that is the bit i am struggling with, trying to get enough diffusion tonot see the individual LEDs, but not too much that it looks soft
I need a bit of help with this. I have the stick working fine using the fastLED sketch and can make lots of different light patterns but no matter what, I can't get the image (neopainter) to work.
I have done the 3 check stages and they all work correctly, lights on their own, SD card being read, and power.
When running the neopainter sketch nothing happens, no lights at all.
The only thing I can think is wrong are the components I am using to make the switch

Anyone have any ideas
Have you set all the configurable items on the NeoPixel_Painter sketch, CARD_SELECT and CURRENT_MAX are the 2 that usually need changing from default
I have CARD_SELECT 10
LED_PIN 3 this is my data input
I haven't changed the CURRENT_MAX as I assumed that this is standard for the 5v coming in from the UBEC
Not sure then i'm afraid, you say all the tests work up to the point where you put the NeoPixel_Painter sketch on, and then it stops working
Yep all working apart from drawing images. I think I will try replacing the 10k pot and switch. Its probably something simple that I'm just not seeing
Are you putting the images in a folder on the SD card or straight on to the card?
They need to go straight on the card
Are you putting the images in a folder on the SD card or straight on to the card?
They need to go straight on the card.
Also have you tried it with just one image on the card as it needs to process them first?
I take it your images are 144 pixels wide? They need to be rotated so the width is right or they don't seem to work.
Also they must be 24 bit bitmap images and not jpeg or anything like that.
Are you using your own images are have you created your own, as i once created one and saved it in the wrong form of BMP and it wouldn't work
Also, try it with the Pot in both directions as you may have set it to minimum brightness, hence not showing anything
And remember, the brightness is set on startup, so make you you switch it off when trying different brightness settings
Ok I think I may have it working, like @rpsmith79 said go back to basics. I have the whole thing on a breadboard and now looks to be drawing a picture, I can set the brightness and the speed via the Pot.
I also think that although I was saved as 24 bit, the advance mode was only showing 16 bit.
Just need to get it off the broad and re-assemble and then wait for dark
