You might use neodymium magnets and eneloops for a compact supply
Hi Julian!
Is the Merry Christmas led sign project getting finished in time? Would love to see an update on what you can do with it all assembled. Are you using any chip for controlling the blinking, or is it all generated by the capacitors?
Come on Julian get on with it – now only 3 days to go!
Maybe hang some little stockings underneath to hold the batteries. Then you could have 3 or 4 to increase the run time and change them one at a time as needed for a continuous run since they are in parallel.

Is this for christmas 2017?
How about a stack of three CR2032 batteries for your nine volts? Held together by magnets or just a rubber band or tape should do it. They'd could be fit in the leaves without sticking out the back.
Hey Julian, maybe a nice idea if you are going to use the 9v might as well get the rechargeable via USB, seen your video on the 18650 and apparently every rechargeable battery now has a micro slot in it, could make a neat micro USB recharge circuit to recharge them when they are running low!
I like this. I'm looking forward to seeing it lit up.
switch to "happy new year" to buy some time.
Interesting idea. I must have missed the other videos about this. How hard would it be to turn this type of circuit into a larson scanner? I've always had a fascination with those since the original Battlestar Galactica. Then Knight Rider came out with one mounted in the front of KIT. I could never quite seem to get a ring oscillator working though. Then there's the addition of an AND gate to make the chase reverse. I'm definitely interested to see how you work it out. The only way I've been able to so far is to use a 555 timer, a decade counter, and a basic diode AND gate. With that I can only get a 6 LED scanner working and I'd love to make one a lot larger, say 20 or so LEDs.
Will this be finished for this Xmas? 🙂
Hej Julian, what kind of glue gun do you use?
I was thinking of something like that too, by put them behind using the back as a reflector and use a spacer to lift it off the wall. hallow around it
Julian, why don't you … Never mind, you're almost done.
no build-guide at the end? i´m a bit dissapointed…
you could use something like a decorative "christmassy" little bag, where you put in the 9V batteries.
How about some of the smaller lipo flat packs? I would think there would be room for them in some of the larger letters. Then add one of those little USB charger modules that you have shown before. You would have a complete stand alone rechargeable sign, that would hang flat on the wall.
Make a bracket for the sign and have somewhere for the batteries where they can be easily changed for next year.
How's about powering it using a few small Lipo cells and a charge controller module?
