In this video I show how to make a Modustrial-designed DIY “Living Art” LED lamp from plywood and an LED matrix.  

The LEDs in the lamp are controlled by an Arduino Nano that creates colorful moving patterns, aka, “living art.”  However, it is also very practical for use as a desk lamp, table lamp, or bedside lamp, since an LED push button allows you to switch from the living-art mode to normal white-light modes, and a red-nightlight mode.   

I made three versions of this lamp – two out of bamboo plywood, and one out of walnut plywood.  You could use any type of plywood you like to build the lamp.

The electronics were designed to be very simple.  It can be built with NO SOLDERING.

Making a Waterfall Countertop with LED River Inlay || DIY Concrete (GFRC) || Mancave Makeover Ep. 1

New build video is up on my YouTube channel.  This video explains how to make a one-piece DIY concrete waterfall countertop with an inlaid river of flowing LEDs that cascades over the waterfall edge (using neopixel LED strips).   

This is the first of two videos for a mancave makeover at a friend's house.  Part 2 will be uploaded within the next week, and will show how to make and install a reclaimed wood feature wall with floating LED TV panel, and the installation of the cabinets.

The countertop is made from a glass-fiber reinforced concrete (GFRC) concrete mix, which is pre-cast in a melamine form.  I made the mix from scratch (recipe links are below).  I mixed 280 lbs of the dry materials (including powdered pigment) all at once, so the color would be consistent.  I used 40 lbs for the face coat, and the remaining in batches for the back coat with glass fibers.

I used an off-the-shelf LED controller that has MUSIC REACTIVE modes, chasing modes, and solid color modes, with an RF remote, to control the WS2812 LED strips.  The LEDs are covered by a smoke grey transparent acrylic sheet, which is inlaid so it sits flush with the concrete countertop.

MM-Inspired Build - Chris Gagnon's DIY Pendant Double-Ring Light

Chris Gagnon shared a video documenting the build process for a double ring light, which he indicates was inspired by Rings of Saturn light.  I think it came out pretty cool - well done Chris!

Here is what Chris said about the project: 

I wanted to put my own twist on it by using segmentation. I have always been interested in wood segmentation and the projects that you can make with it. This project is inexpensive and requires very little tools. All your friends will be so impressed when you start making things using this new skill you are gonna learn here. One thing I want you to take away from this video is that you don’t need to spend hours building a fancy jig for your table saw to do perfect segmentation projects and I am going to show you how right now. so lets get started.

And, in case you haven't seen it, check out the original video for my Rings of Saturn light.

Bluetooth Speaker Build Featured on Adafruit,, and Maker Update

The Bluetooth LED speaker build was a passion project for me, so I'm excited to see it getting some positive press.

Check out a great overview of the project on Maker Update's weekly maker news show, where it was the project of the week:


The speaker was also feature on Adafruit's blog and

NEW BUILD VIDEO -- DIY Bluetooth Speaker w/ Reactive LED Matrix

My new build video is up -- check it out!

In this video, I show how I designed and built a Bluetooth Speaker with an integrated LED matrix. The LED matrix includes a number of different visualization modes, including a fireplace mode, an abstract “moving art” mode, and several that react to the music via a microphone inside of the speaker box. I haven’t seen any other product designed for the home, which marries sight and sound in this way.

The idea for this project came about in a somewhat unorthodox way. I wanted to build something for several friends expecting newborns. I wanted a gift that would help their children develop neurologically, and a gift that they wouldn’t outgrow. Having done a number of LED projects, and having some woodworking experience, I came up with the idea to integrate an audio-reactive LED matrix in a Bluetooth speaker.

The speaker box involved a fair amount of woodworking. The outside of the box is made from rough curly maple lumber, which I milled to 3/4". The front and back panels are made from MDF. The finish of the curly maple was inspired by electric guitar finishes, like those seen on some of my favorite Paul Reed Smith guitars.

Internally, I am using a 2x15w Dayton Audio bluetooth amplifier board for the audio, and an Arduino Mega to control 16x16 LED matrix (WS2812 LEDs). A small electret microphone inside of the speaker box detects the music that is playing, and provides a signal the Arduino can use to create reactive display on the LEDs.

The design also allows for mechanical adjustment to entirely change the look of the LED matrix; from pixelated to abstract. I am particularly proud of this feature, as I haven’t seen it anywhere else before, and the effect is very cool (it is shown towards the end of the video). The LED matrix is mounted to a baffle behind the white semi-transparent acrylic diffuser, and by twisting a thumb screw on the back of the speaker, you can move the LED baffle towards or away from the diffuser. The thumb screw thus allows you to go from a pixelated display (where individual LEDs are visible), to an abstract display, where the LEDs blur together to form moving art, with an almost 3D-like effect.


MM-inspired Concrete and Live-Edge Inlay Charcuterie Board

The Cutting Bored just uploaded a video of their concrete and live-edge inlay charcuterie board.  (I'm trying to resist saying its a cutting board by the Cutting Bored :) ) The video indicates this board was inspired by my live-edge table build video, but this is really a unique twist on the design.  They used inexpensive materials and still got a great looking result.  

Generally, The Cutting Bored has a great YouTube channel going, so check out the rest of their videos as well, and show some love by subscribing.

For those that missed it, here is the original live-edge white concrete table that the Cutting Bored references in their video.


New Build Video is Up! Stunning and Simple-to-Make Concrete & Copper Coat Rack

In this video, I show how to make this DIY geometric concrete & copper pipe coat rack (or hat rack, or skateboard rack, whatever you prefer).  This build is really easy to do and fairly inexpensive.  It uses a cheap 3D PVC tile as the base of the form, to give the coat rack its geometric shape.  You can buy any sample of one PVC tile, to customize the geometric shape of the rack how you like.  

The project uses Fishstone GFRC concrete mix so that the tile can be cast at only ½” thick, and be light enough to hang on the wall.  This is a “just add water” mix, which is incredibly easy to use.

I embedded copper pipe pieces in the form and poured the concrete right around them, so that they would serve as posts for hooks.  I then used more copper pipe to build hooks in interesting shapes, around the embedded posts, after the concrete cured.

This was a fun experiment, and could lead to all kinds of things that could be made using this technique for PVC tile as a concrete form.  

A few edits to the commentary -- thanks to my subscribers for pointing these out!

1. Nail polish remover (not nail polish) cleans copper pipe.
2. I used a hot glue gun on the concrete form (not super glue).
3. The GFRC mix takes 1 gallon of water per 50 lb bag (not 1 lb).

NEW Build Video! Simple Way to Turn Scrap Plywood & Leather into a Modern Amazon Echo Stand / Desk Organizer Tray


I made this simple modern desk organizer, with a built-in stand for my Amazon Echo Dot, from scrap plywood and a scrap piece of leather.  The plywood was a piece I had leftover from the #kregonesheetcontest.  

This is a really simple build I think anyone could do.  You could make it with only a circular saw, a drill, and a jigsaw if you wanted to.

Project Updates: Man-Cave Makeover and Cantilevered Live-Edge Table

I always have a couple projects in the pipeline for Modustrial Maker.  Right now I'm working on a man-cave maker with my friend Al, which actually is a few projects in one: reclaimed wood wall, concrete countertops, cabinet install, and LED TV wall.  Here is a quick video of the reclaimed Stikwood wall going up.

I'm also working on a cantilevered live-edge maple table with an angled concrete post as the base.  I haven't seen anyone else make anything quite like it, and am really excited about the design.  The video will be up next week.
