Since dusjagr's visit to Taipei in October 2018, we got completely hooked up with those LED-NEON tubes to be used for making simple DIY signs, artworks, installations, workshops and more. Together with the artist duo Veli & Amos we experimented using them for next-gen demonstration banners, solar-powered public mobile billboard-on-a-car and more to come soon... This is not a commercial!

General Intro

NEON-LED rawMaterial.jpg

We experimented with various different versions of these LED Neon tubes (search for "Flex LED Neon Light" on aliexpress.com), ordered them from China, which can take 3-5 weeks. There are different versions, most important is the Voltage! They are sold as 220V, 12V (and 24V). All have their own use, benefits and cons.

We advise to get started with the 12V tubes, makes your life easier, less problems with high-voltage, less danger and easy to dim, or control with switches or microcontrollers. And most importantly the 12V tubes can be cut as you want every 2.5 cm.

More about 12V tubes

When ordering the 12V tubes, make sure you get the high-density "120leds/M" versions, for a more uniform NEON-light effect. We found two different versions of tubing, one is kinda whitish tube and the color is only visible when the LEDs is powered on, the other is using coloured tubing and when powered on gives kinda a more smooth light. It depends on your style and design ideas, but generally we preferred the coloured tubing, also it's easier to find the color of choice in a bag full of little pieces of tube!

8mm medium thickness

Our favorite supplier for the coloured tube is here on aliexpress. Best to order a few different colors and at least 4 meters each to get started.

They come in various colours, usually from cold white, warm white, yellow, green, blue, red and pink, somtimes a store might have 1 or 2 more colours available. Another version is "round" tubes, which are not covered in this description, cos they can't be easily glued or mounted to a board.

5mm thin / flexible tubes

There are also slightly thinner LED-NEON tubes that are more flexible and useful for smaller signs, also they are slightly cheaper.

Power Supply / Netzteil 12V

For the 12V tubes you will need a trafo also known as 12V power supply, or "Netzteil", which you might have lying around in your house or you can find them in many many stores. check the rating, it has to be a 12V DC output, and if your sign is getting bigger and bigger, make sure they have enough power, which can be read as "A" for Ampere, or as power something like 30W, 100W. For small signs, the same store sell this one, 2A, and it comes with a little switch. For larger signs or the whole room lighting best to get 5-10A. It might not come with a Swiss plug... but you can also search on Ricardo.ch or ebay.ch for local suppliers or get it from Conrad or any other local electronics / household store. They start at around 6CHF and go up to 30CHF for more power.

Nice little power supplies with adjustable Voltage. Small 3A or bigger (with display) 5A.

For "smaller" signs a USB-step-up converter can also be used. Found on AliExpress.

Error creating thumbnail: convert: delegate failed `'dwebp' -pam '%i' -o '%o'' @ error/delegate.c/InvokeDelegate/1928. convert: unable to open file `/tmp/magick-3228302hI4VHnVhU0L': No such file or directory @ error/constitute.c/ReadImage/604. convert: no images defined `/tmp/transform_43a7856ae5d6.png' @ error/convert.c/ConvertImageCommand/3235. Error code: 1

DC plug and socket

As we are making the signs ourselves, we will also need to add a DC socket (female) on the side of the LED sign, to be abe to plug in the DC plug (make) of the power supply or add a battery. Best to go to Pusterla or Conrad with your power supply (Netzteil) and make sure it has the right size and fits tighly. Sadly they come sometimes in weird dimensions. But most of them come with this kinda standard size.

DC dimmer

12V DC is easy to dim... many units are available on Aliexpress. Some of them work with PWM, or you can adjust the voltage with a DC-DC step down converter.

This really cheap one from Aliexpress


Or this one from ali in white or black


Some info about the 220V tubes

They are also useful, if you just want to add a single color tube / line in your room, a wave, a little heart etc, and they can just be plugged into the wall plug. The tubes already come with a little integrated converter and a plug. BUT they can only be cut every 1m, so they are not suitable for a LED sign that combines different elements, or if you want to combine different colored tubes in one "painting".

Other tools

  • Side cutter
  • Plier (flat)
  • Super glue (instant glue, Sekundenkleber)
  • Hot-glue
  • Soldering iron and solder wire
  • Strong wire

How to make them
