A Lego Mosaic Printer

JK Brickworks made this amazing “pick and place” style Lego Mosaic Printer:

It is built entirely using LEGO parts. It first uses the EV3 colour sensor to scan the source image and save the data on the Mindstorms unit. It can then print multiple copies from the saved image data. The 1×1 plates used for ‘printing’ the mosaic are supplied using a gravity feed system and the printing head is simply a 1×1 round plate that can pick up and place the 1×1 plates.

More information about this project can be found at JK Brickworks.

WaterColorBot and BeetleBlocks

The Tinkering Studio posted on twitter:

BeetleBlocks is a system for enabling people to explore algorithmic 3D geometry by snapping together Scratch-like programming blocks.

They posted a picture of the finished painting, which looks awesome.

Fab Academy CNC Workstation Cart

Erin posted on the Make blog about large scale CNC projects at Fab Academy, including a CNC workstation cart based on our design made by Lina Monaco. Lina goes into more details in her post here.

To design it I started from the Evil Mad Scientist’s CNC Workstation Cart redrawing to adapted it to our necessity as an horizontal PC, cables space inside, and last but not least without any screw or glue.

No screw no glue drawers

She posts about her design process, including prototyping using a laser cutter to make a scale model. It looks great—we especially like the cutout drawer handle design.

Meggy Jr RGB + WaterColorBot

Our friend Schuyler hooked up our Meggy Jr RGB hand-held video game platform up to control the WaterColorBot. He wrote on twitter:

I got the @EMSL Meggy Jr RGB working with the @MakerSylvia WaterColorBot. My code is here. https://github.com/docprofsky/meggyjr-cncserver.

The output looks great, too. Thanks for sharing your code, Schuyler!

555 Footstool for Sparky

Sparky the Blue Smoke Monster on 555

Adafruit just got a new chip for Sparky the Blue Smoke Monster! It turns out that our 555 Footstool is just the perfect size for the Sparky puppet they had made.

555-1508-1

As before, we cut the parts out on the CNC router from our original design.

555-1508-7

The parts were glued together and sanded.

555-1508-11

After assembly was lasering to mark and etch the notch, which we carved and chiseled to make it deeper than our previous one.

555-1508-13

The first layer of paint was primer grey, followed by black and silver. Once the body of the chip had a beautiful matte black finish, it went back into the laser for the manufacturer’s mark before a final protective coat of paint.

555-1508-15

It posed for a few pictures before heading off to meet Sparky, and we’ve posted them on flickr.

GeekDad on the EggBot

Mark has posted a nice writeup at GeekDad about receiving an EggBot as a birthday present:

It was the perfect gift for a GeekDad–something I wasn’t expecting and might not have bought for myself, but is so much fun that I wish I’d bought one years ago.

30 valentine ping pong balls

He used it for his daughter’s preschool:

In almost no time, I had a box of 30 Valentine’s ping pong balls for her to take to school. Her teachers were fascinated when they saw them and I was told had been debating whether we had somehow hand-drawn them all. The head teacher asked my daughter how we made them and she naturally replied: “No, a robot drew them!”
