While looking at various projects on the tinterweb I saw a couple of things I liked, a fire / flame effect and a sound level meter, so why not combine them into one?

I have a 3D printer and various bits so this was a quick (not counting the 9 ish hours of printing) job.

All you need is some clear filament and a colour of your choice, or just more clear if you want. In the words of Bob Ross, its your world and you can do what you want in it.

First off, get some bits on order (see step 1)

While you wait for those to arrive get the printer out and set to work printing (see step 2)

Assemble the parts (step 3) then sit back and enjoy :-)

Supplies

See step 1, I didn't know this bit was here :-)

Step 1: Parts List

I had most things kicking around from other ongoing projects and this is the short list of bits you need, these are all from Aliexpress but are available all over the place (Google is your friend!)

1 Arduino Nano (or similar)

2 WS2812 144 LED strip (only used 20 on the larger and 16 on the short version)

3 MAX4466 mic with preamp

4 Slide switch or latching push button

5 Mini USB breakout

6 1 x 10K resistor

7 Access to a 3D printer

Step 2: Get 3D Printing!

There are only a couple of parts to print and the tube is done in two lengths, the shorter length is set up for 30 pixels per meter and the 150mm tube is adapted to take the 144 pixels per meter (they are wider which I didn't realise!)

I did the locating ring which you glue to the bottom of the base, you don't need it but it makes life a lot easier, hot glue or superglue that puppy onto the bottom of the larger cap.

The caps are just push fit into the tube but you can glue them in once you have confirmed everything is working.

On the base the tiny hole on the front was supposed to be for a push switch (mounted inside the base) but it turns out the "latching" switches don't latch, so I filed it out and added the slide switch instead.
