Summary

Do your own "cartel luminoso" (signboards, placard?? I don't know how to say that in english, sorry) with LEDs strips!!!
I made a full alphabet for you!! So you can print the words you want, put inside the LED strip and It will be already to use!!

I made "EL NARDO" for my xaranga, ( a kind of music band here in spain), It's 0,75 metres long, with RGB LEDs strips.
We went to play in a band contest, and I proposed to make something cool with my 3D printer, something new, something anybody has, but the "boss" said no, but I thought it will be a good idea, so I made it and I give it to my xaranga as a surprise!!
All of them were in shock when they saw it few minutes before our turn to play !! And now we use it in every gig!!!!!!!

People use to take photos with it when we are playing, and anyone believe my when I say I made it with a 3D printer!!!!!

Now I made another as a present for a friend of mine, he plays the clarinet in the video, when he saw the nardo's placard he ask me If I can do it bigger for his company and of course I can!!! 2m LONG!!!!!
This year, during the town's festivities, he is going to be the captain of his company: LLAURADORS, ( villajoiosa, Spain), and this is his present for them!!

The premiere is tomorrow (24/07/2015), I will take photos and videos!! I'm very nervious, because I don't know what the reaction of the people will be!!

  • The font of LLAURADORS is different because it is like the logo of the company, but it's the same design for the bottom and top side than the alphabet I uploaded

https://youtu.be/QB3zKkhmouE

it was a success!!!!! The people of the LLAURADORS company love it!!
this is the moment when they saw it!
*I'm the guy with the blue t-shirt, I was playing with my xaranga, El Nardo, in other company, i went to see the result of my job

Instructions

  • Download the zip files, STL or SLDPRT,

  • Choose the letters you need (without misspellings)

  • Print the top and the bottom of every letter

    • you can print everything with transparent filament, like EL NARDO or print the bottom in the colour you want and the top in transparent or natural filament like LLAURADORS
  • Put the led strip in the bottom side, the holes is for the wires, to connect the letters

  • close the letter with the top side, use super glue

    • I only made the holes for the wires, I don't made any hole to fix it, because it depends where and how you want to use it,
      because of that, I upload the sldprt files ( Solidworks), so you can edit it!!

    • tip: for " LLAURADORS" I made the holes to fix it in a L profile, using M8 screw, I put the nut into the bottom side using the soldering iron.
      And the distance between holes is 25mm, so i put every hole in the letter at 25, 50 ,75...

the size of the screw, and the way to fix it depend on you, even you can use superglue to fix it

Also you need:

  • LED stripe
  • wires
  • Soldering iron
  • super glue

hola, estaba pensando en hacerme un minicartel para mi casa... y entonces se me ha ocurrido mirar en thingvierse... y mira que me encuentro a un "super spanish" :-P

mi idea era hacer unas letras (para poner encima de mi ordenador de juegos) y que esas letras tuviesen los leds apuntando hacia la pared (para tener luz indirecta), no se cómo se llamará esto.

Con mi idea creo que valdría con hacer la parte "bottom" de cada letra y pegarlas a la pared (bueno realmente a una madera) a una distancia, para que la luz que se vea sea sólo la reflejada...

¿Has intentado hacer algo como esto? haciendo las letras en PLA negro sería suficiente para que no se vea la luz de los leds salvo en su reflejo?

Gracias por adelantado y un saludo.

Buenas,

Pues lo que dices no lo he probado, pero si yo tuviera que hacer algo así intentaria dos cosas.

(los filamentos que te indico son los que yo empleo actualmente)

1º invertir la letra, y que la "tapa" corresponda a la parte trasera de la letra. Así lo hice con el cartel del Nardo.

Entonces usaria PLA Natural . Y le daría un porcentaje alto de relleno 50% +-. Con esto la letra se ilumina pero no pasa mucha luz, y dejando la tapa abierta la luz saldria directa e iluminaría la pared.

http://www.3dcpi.com/es/filamento-3d/pla-plus-3dcpi.html#/espesor-1_75_mm/color-natural_fdfaed/peso-1_kg

2º Haria las letras solidas si es posible en una misma pieza con un 20-30%. Plana sobre la impresora, que las letras esten paralelas a la superficie de impresión. Y una unica tira de leds detras en lugar de con la forma de la letra. Eso en PLA Natural saldría bien. Pero yo lo haría en PETG Transparente

http://www.3dcpi.com/es/filamento-3d/pteg-3dcpi-esp.html#/peso-1_kg/color-transparente/espesor-3_mm

Como pones la cinta de leds sobre el fondo de la letra?, la vas recortando y uniendo con cables? y entre letra y letra? estaría bueno si podes subir una foto donde muestres la letra sin la tapa y que se vea como colocas la cinta de leds adentro.

Gracias de antemano

Hola,

Pues ahora mismo no tengo las fotos, y no se donde las metí, pero en cada cartel lo hice de una manera diferente.

El Nardo: En este cartel fui pasando la tira de letra a letra, y no se nota por que las letras estan muy juntas. y como está hecho con color natural y brilla todo, la tira no esta colocada al fondo, si no en las paredes laterales.

LLAURADORS: en este caso fui cortando las tiras y soldando los cables. los cables los fui pasando por detrás del perfil. Asi que hay soldaduras dentro de las letras y entre letra y letra, mas que nada para intentar pegar bien las tiras al fondo de la letra

Te agradezco por tu rapida respuesta. Voy a hacer un cartel como el de LLAURADORS que se lo ve espectacular. Cualquier duda te pregunto... nuevamente gracias por responder y por compartir el proyecto.

Gracias a ti, y acuérdate de subirlo en cuanto lo tengas!!

Pd: las letras que he hecho son solo de referencia, para que se vea como están montados los carteles. Pero después la fuente y por donde salen los cables y demás es decisión tuya.

Yo descargo las fuentes desde dafont.com y de ahi escribo el texto y empiezo a crear las diferentes partes.

Hi! Nice Job! Have you do numbers please?

I want to do the numbers, but I have no time, I'll do it soon, Why don't you try to do it yourself? it's very easy, the top side is 0,2mm ( each side, equidistant) smaller than the bottom side to fit inside one to the other. The other things, like the edge, is up to you.

Ok I will try it with solidworks ;)

Fantastic! This is great. Can you please also create numbers 0-9?

+1 for numbers! I think this would make a great new house number for my front door! :)

Jay

I'll do it!! but now i'm on holidays :D :D Next week, when I'll be back!
