Hi guys,

..finally here it is → my BIG Spiral Lamp V2 [WLED] :)

I heard your voices and created the lamp from scratch in order to make a lot of things easier. I also added a video tutorial howto assemble the lamp. everything is in realtime and you will see how easy it is. the assembly will not take longer than 5 minutes!

Features:

• full support of WLED
• easy print with less filament compared to the previous version
• really easy assembly!
• the WOW effect :)

You need some hardware:

• 1.5m ws2812b LEDs (3x30 LEDs or 3x50cm stripes)
  • https://www.amazon.de/dp/B0BTVBTHQ5?psc=1&ref=ppx_yo2ov_dt_b_product_details
• 2x3 male, 3x3 female wires for soldering. I used these jumper wires: https://www.amazon.de/gp/product/B01EV70C78/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
• 1 x ESP32-C3 for WLED → I used this one: https://www.amazon.de/dp/B0CPY6LMSJ?psc=1&ref=ppx_yo2ov_dt_b_product_details
• solder skills

If you want to use another board contact me and send me the size(s). I will try to also create a fitting lid for your board! Currently the profile contains a “standard” size for ESP32 mini boards with 35mmx28mm (length/width).

How to print:

First of all please READ the whole instructions!

As I wanted to make the assembly as easy as possible I decided to design a guided rail for the stripes. Everything matches perfectly to each other especially the diffusors. BUT - you really have to make sure to use CALIBRATED (or BAMBU-), DRYED FILAMENT! I will really be pissed when someone is giving a bad vote due to the fact he was unable to READ! ..and believe me - this happens a lot and is really frustrating.. The printer is doing it's job pretty well but this does not exclude any work / maintainment!

Here are some rules / hints to get a perfect result:

1. USE A CLEAN PRINT BED!
2. USE CALIBRATED OR BAMBU FILAMENT!
3. USE DRY FILAMENT!
4. USE NORMAL SPEED!
5. REMOVE ALL SUPPORTS CAREFULLY
6. MAKE SURE TO REMOVE ALL SUPPORTS FROM THE DIFFUSORS ESPECIALLY THE BRIM

When you don't want to use my print profile pay attention to the following points:

• use NO infill for the diffusors
• use max. 2 walls for the diffusors as with more walls less light will come through
• you need stabilization for printing the diffusors & the two main lamp parts → NO supports WON'T work! (I already tried that with my big spiral lamp V1 and always failed due to the height and small movements caused by the mass inertia). tree supports work best.
• the lid surfaces should be printed in a circular way. so ensure to choose a propper setting for the bottom & top layer!

The filament I used:

• transparent eSun filament for the diffusors. You can also use the Bambu PETG Basic profile and have no issues! https://www.amazon.de/dp/B07FXVGYKL?psc=1&ref=ppx_yo2ov_dt_b_product_details
• Bambu black:
  • https://eu.store.bambulab.com/de/products/pla-matte-filament?variant=43992833261787
• Giantarm gold silk as I ran out of bambu gold silk :P. You can also use the Bambu PLA silk profile and have no issues!

How to assemble:

Preparations:

• Cut the LEDs (3 stripes)
  • If you are using the 60LEDs per meter stripe then count 30 LEDs and then cut it. Insert the stripe and test whether the lenght matches (it should - you can also cut after checking ;))
  • If you are not using the 60LEDs per meter stripe measure the length → just insert the stripe into the lamp. The leds should end within the lamps body on both sides this way (you just see a small edge of the stripe):

• Cut the cables in the half, strip the insulation and solder ONLY the females to the inputs (see the arrows on the stripe!):
  • always use the male plug for the output and the females for the input

• Flash the ESP32C3 board like described here:
  • Download the flasher software
  • Download the binary (this is the one fore ESP32C3 - if you use a different board then you have to select another bin)
  • Flash how it is described
• May already configure WLED starting at 3. from here (if you have any issues just ask here and I will help you guiding through)

Now watch the assembly video:

Now the lamp is assembled. Push / Pull the stripes from the two sides this way and solder the males:

Push the stripes back (never pull the cables) and connect everything. Start from the side with the two female stripes. Choose the one you will use as input from the board. Follow with your eyes to the other side. Connect the males at this side with the only females. Follow the female stripe back to the other side. Connect the males with the females of the remaining stripe (NOT the one which is the board input).

Now connect your board. The PIN setting is the following way:

• green is LED+ → it connects to 5V
• grey is LED- → it connects to ground
• white is DATA → it connects to GPIO2

Power the board. When your solder-points are ok the first 30 LEDs of the lamp should shine orange. That is the default setting in WLED to check whether everything works. If you have already configured WLED then all 90LEDs should shine (if not either your solder-points are not ok or you connected the wrong stripes :P).

You are done :) Enjoy your new lamp and leave a like :) (don't forget to assemble the lids :P)
