This one is not as fancy build as some others I have mentioned, but still a nice build.

Basically its an LED scroll sign using bluetooth and an arduino to control it. I like the build, except the LED strip it $40 (before shipping). Seems like a bit much for me. I found smaller ones for $24. I think I will wait for prices to drop a bit more before getting something like this.
I have see a few of these builds over time, This one is a bit nicer than some others I have seen.

Basically its a system with a bunch of solenoids and servos. Its nice to look at how they are going about building this.

The author put alot of thought into support for the table, and angles inside to “roll” the dust towards the vaccum.

Neat build, the author 3D printed the hardware and uses an arduino as the brains to sort M&M’s.
Pretty simple jig that you can use on your tablesaw, or bandsaw.

I like this build, I think it could be make a bit easier than the way the author did, but whatever works right.

Not so sure I would have made the wheels by hand like the author did. Instead I think I would use rollerskate wheels for 2 of them. Either way nice build.

Pretty nice build, I like this author, he does some fancy builds with pretty basic materials, and is not into the “must look fancy” bit too.
