DIY LED-NEON Signs
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-voltages, 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.
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".
