Meggy Jr RGB + WaterColorBot

Meggy Jr RGB controlling 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.

EggBot in Budapest

Kitti in Budapest has a thoughtful blog about her EggBot. She’s posting her experiences, modifications, and challenges. She is putting up designs on Thingiverse, starting with the Hungarian Folk design shown above.

My first design was inspired by my Mom. I told her about my plans to draw something in Inkscape to be printed on an egg later. She immediately ask if I am planning to do a Hungarian folk pattern.

We’ll be looking forward to seeing what comes next!

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!”

From the Mailbag: Long-term Lego Storage

1x8 flat - 5

This great question came in via email:

I was wondering if you are still using the Lego stacked storage system you blogged about 3 years ago?

We are (it’s actually been eight seven years since we wrote that post) and it’s still working well. Last time I went to do a Lego project, I was particularly pleased to find that our parts were still mostly sorted and easy to get at.
