#B-Lamp custom design
mortal whale
hello, my own lamp design that i have worked on the last couple months
here is a vid showing off how i did the disconnecting in a showreel

The video gives away the same energy that he had on the Makerfaire in Hannover when somebody walked past his booth.
Smiling in the direction of the person and changing the tower. 🤪

i must say doing it in the forest, semi scripted was allot harder to do
i am using 16 pogo pins that are all aligned to outside for the data and power/ground connection
i was in a 40 day time crunch to compleet it for the makerfair in Hannover.
and with that no time to learn first time making a pcb or the other ways to do it beter.
currently slowing learning kicad to make a custom pcb and adding the led solderless wire connector making the single layer version compleet solderles and easier to assemble
as i will do my best to get that version on printables so others can build it to

Neat project, and impressive modularity.
mortal whale
Thanks 🙂
Hopefully with a new pcb and knowledge going to try to build as high as i can

hey @mortal whale saw a video of you from makerfaire. very nice project! would love to make one for me at home. looking from the photos it looks like you daisey chain all the vertical strips by looping the end of one strip on the top with the beginnen of the next one at the top with wire loops. how are you updating the led count in the effects you use? and how do you control the effects? is it custom or wled or something,
i have some pcb skills myself from me previous big wled/led project but now i want to make something to use indoors and your project looks very nice!
mortal whale
hello
i know 4 layers was the max and told Wled here are 448 leds in total
and when i disconnect one set it still thinks it is there
atm making a 1 layer no pogo pin version for printables and able to sell.
at the moment no plan yet to sell the stackble as for more people if the dont realise the stack to high with not enough amps for the total distance
so with that
the small version will be without soldering and currently learning how to make a pcb for that goal.
possible after that i learn how to make a safe way for the stackeble version to.
people with more knowlede in electronics say its possible with good safety and wont burn down!
and the stackable version wont need 16 pogo pins
saving allot of soldering 🙂
current 1 layer not stackable version is fully fitted with connector wire saving all the soldering

I think if you keyed the lamps so they only connect one way and then added a dedicated power backplane that ran down the center you could get away with almost unlimited height. Run the backplane at a higher voltage and step it down in the lamps.
dry sorrel
in his setup he has a single point of injection iirc.
so the complete current has to go through the pogo pins.
which is the limiting factor.
mortal whale
Well that is the next step plan with the 10amp pogo pins and making a multi path system but that all is a theory as i am still learning how it all works
As i saw in wled 488 leds which are a meter in total length can ask a max 10/12 amps. But average is 2/3
So with 1 power supply and pogo pin chain i should be able to reach 3/5 meters if you cap the max brightness down stopping the amps going over the max
dry sorrel
in theory you could modify your exsisting modules easily to allow more current.
just combine all positives and negatives together.
and have seperate wires connecting top and bottom.
but that means more soldering 😉
mortal whale
Making more path wont mater with the current small pogo pins the only can take 2 amps
dry sorrel
that is one, but if you have 16 pogo pins in parallel you can handle more
mortal whale
That is current setup and yes to much soldering xd
Hopefully with the 10 amps pogo pin and each section its own esp32 i can control the amps beter
Than i can do 24volts travel path and step it down back to 5v for leds and chip
But that is all depended on me understanding pcb making at the moment 🙂
dry sorrel
I meant this
and that is just one of the power pins.
same for the other
the datawire is still only connected between Pogo and Led
mortal whale
If that is all one esp than the max is 800 leds +-
dry sorrel
depends ;D
i have an esp32 driving an 4096Leds in an matrix (though those are not ws2812b)
the main issue is the output speed of the data with ws2812b
apa102 can be way faster, but the leds are also more expensive
mortal whale
that is where i was heading to with my current knowdledge
i made some mistakes >_>
not good at written schematics at all XD
stupid phone
dry sorrel
wait you have 16 led per strip °°
oh boy the ESP32 P4 can have 16 parallel outputs.
🤪
but P4 is still very early stages.
mortal whale
i have 7 leds times 16 strips total in 1 section is 112 leds in a section total
the 2 wire between the esp make it that the can talk to each other by wire not wifi
and know where there are in the total stack of layers
so leds at the end of a section dont need to push data to the next layer
and with testing and limiting the brightness i can see a average of only 0.5 to 1 amps needed in 1 section
without that you actual see much drop in visual viewing

This is super cool.
I am not sure what is the actual usecase here, but still super cool.
mortal whale
yeah the stacking is mostly used by me at events to make something popout at the floor so everyone in room range can see it 🙂
so in core its mostly a booth attractor

yeah the stacking is mostly used by me at events to make something popout at the...
actually that was my idea that it could be good for event orginezers. where they have to decorate, and clean up a venue quickly. it is an adaptive (shape and thanks to wled the behavior as well. It can work with with some slow white effect in a wedding, or full on rgb rave mode on a lan party) design, so it can work in variable places. maybe there is a market for it? 😄
Or decoration, where you have to take it out and put it away sesonaly. And can work for halloween and christmas as well.
mortal whale
yeah 🙂
making a none stackable for all the get on printables in time.
But settings all things up takes some time

and yeah i keep having fun with it 🙂

aiming to walk around at formnext and show it to people

Hey-hey
I just want to say congrats for this lamp. I saw it multiple booth on formnext as decoration/showcases.
Keep up the good work! 🙂
