From the Mailbag: Interactive Game of Life

Game of Life by Forrest

Forrest shared these pictures of his Interactive Game of Life build.

I bought the project to help expose my two grandsons to electronics and learn how to build circuit boards.  Dan my 10 year old did one board all by himself just using your instructions. Josh my 14 year old did more than half of the boards and I finished them up because I only have the kids for limited time periods. I am so proud of them. Josh complete understands how the Game Of Life works…I don’t  HA!  We are planning on adding a instruction board to the bottom of the display so other kids can have fun.

I have a CNC router and built the frame.  The boards are screwed onto a piece of 1/4″ plywood which floats in the frame.  Not glue in.  I machined a loose slot around the inside frame pieces.  That way I can take the frame apart and easily change out of a board if necessary.  It has been so much fun to build and you have SUPER service.

We thank you so much and would like to build more projects that you may come up with.  As soon as I get more time with Dan we are going to build the clock.

He also shared his case design (105 kb dxf). Thank you for sharing your time and skills with your grandkids, and for sharing your pictures and design with the rest of us!

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.

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!”
