Blinky AVR Earrings

Blinky AVR Earring

Look what just arrived in the mail– Blinky AVR Earrings!

Blinky AVR Earrings

Not long ago, Rick posted on twitter about the ATtiny84 blinky earrings he had made, inspired by my voltage regulator earrings (which I now fasten on with the appropriate phillips screw).

Four blue LEDs blink in sequence, powered by a CR1220 battery. The board is traditional OSHPark purple, with an ISP header for convenient reprogramming. They’re lighter than they look and quite comfortable.

Thank you, Rick! I know what I’ll be wearing to Maker Faire!

Congratulations also to our collaborators on the WaterColorBot project, Schuyler and Roger who won gold in Art Bots in the Painting category.

STEM at the White House Easter Egg Roll

Families gather around to learn more about how the EggBot works

From the White House Office of Science and Technology Policy blog post, An Egg-straordinary Day of Science and Technology:

Interacting with EggBot, an art robot that can paint very intricate and precise designs on eggs. EggBot taught students about digital design, computer numerically controlled machines and robotics. This was also a fun way to celebrate National Robotics Week!

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

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!
