And another special project of mine

While working on "The King's Treasure," I was also writing two other non-LEGO books. (Don't ever do this - completely crazy and will take a few years off your lifespan.) One of these other books is something that I'm extremely proud of and would like to share with The NXT Step readers... it's titled "Build Your Own CNC Machine" and it's coming out at the end of November 2009.

Here's the cover and a couple of pictures for you. Some details:

* It has a 2' x 4' tabletop workspace with about 1.5" of non-usable surface around the perimeter. So, you can realistically work on wood, aluminum, or plastic that fits within the 2'x4' boundary.

* Depending on the router you choose to use, you can work on material up to about 7" tall, but the depth the router can cut down (on the z-axis) is dependent upon the surrounding area not impeding the up/down movement, so the depth of cut into super-thick material will really be limited to your bit depth/length as well as any material blocking the further downward movement.

* The entire thing can be built for less than $800.00. Yes, $800.00US. While most 2'x4' comparable CNC machines are running $7000 and higher, this is a completely reliable and fully functional 3-axis CNC machine. The book provides plans for cutting, drilling, etc... all the parts from MDF (very rigid and strong) and my co-author (Patrick) and I provide parts #s and locations to get all the electronics. Chapters show you how to wire up everything as well as where to get the free software used to control the stepper motors.

During the writing of this book, three separate machines were built - I built one, my dad built one, and my tech editor built one. All three are identical, working right now, and are very impressive to watch.

I can already hear someone asking "Can it cut out parts for my robots?" - Yes, it can. But it can do so much more.

One of the reasons Patrick and I did this book was to make CNC technology available to a larger group of users - traditionally, these machines have been (and are) expensive to own and complicated to operate and repair. Well, when you build your own CNC machine, you know every part, how it all comes together, and you'll know how to fix it...

It's not an NXT robot or product, but if you're into robots, you're sure to enjoy something like this. We have a website, discussion forum, videos, full color photos for downloading, etc... all to support readers of the book who want to build their own machine. We're hoping to hear from students, shop teachers, parents, and after-school groups who take on building their own CNC machine(s) and we'd love to see photos and videos of your machine and your designs.

Again, the book is out in late November... if you have any other questions, let me know.

MINDSTORMS Retires!

2023 is the 25th Anniversary of the MINDSTORMS brand. For 25 years, MINDSTORMS has educated and inspired a generation of robot builders, both children and adults. Unfortunately, the LEGO Group decided to end the line on December 2022. Many ROBOTMAK3RS have been passionately involved with the development of MINDSTORMS through the MUP and MCP programs. Even with the newest Robot Inventor line, several ROBOTMAK3RS were invited to submit additional bonus models that were included in the official app. Regardless of the retirement of a major LEGO robotics product line, ROBOTMAK3RS continue to MAKE-SHARE-INSPIRE using all LEGO robotics platforms available to us. Here is the official statement from LEGO. Since its launch in September 1998, LEGO MINDSTORMS has been one of the core ‘Build & Code’ experiences in the company’s portfolio, carrying with it significant brand equity and becoming a stand-out experience for the early days of consumer robotics and leading to current Build & Code

Celebrating 25 Years of MINDSTORMS

In celebration of the 25th Anniversary of MINDSTORMS, we take a trip through history. Please also visit ROBOTMAK3RS Community every week as we highlight different projects all through 2023 in celebration of the anniversary. Some of the early history is based on the content shared by Coder Shah in our MINDSTORMS EV3 Community Group . Some of the text and links may have been edited from his original posts for consistency and clarity. 1984 - Kjeld Kirk Kristiansen watched a TV program called "Talking Turtle," where MIT professor Seymour Papert demonstrated how children could control robot "turtles" using LOGO, a programming language he developed. 1988 - The collaboration between MIT and LEGO resulted in LEGO TC Logo in 1988, which allowed students to control LEGO models using computer commands. The video shows Papert demonstrating TC Logo. 1990 - LEGO TC Logo was hampered since the robots you built had to be tethered to a personal computer. LEGO and MIT

Celebrating MINDSTORMS with a Remix Part 1

In honor of the 25th Anniversary of MINDSTORMS, we asked ROBOTMAK3RS to combine a LEGO set of their choice with a MINDSTORMS set. Here is what these five ROBOTMAK3RS came up with. MINDSTORMS Chess Assistant by Arvind Seshan Overview: When you are new to chess, it can be a challenge to remember which pieces go where. Now, you can use machine learning and LEGO MINDSTORMS Robot Inventor to build a tool to help you learn where all the chess pieces go on the chess board. Sets used: LEGO® Iconic Chess Set (40174) and MINDSTORMS Robot Inventor (51515) Review: I really like how the chess set base can store all the pieces underneath and that the board neatly splits in half for handy storage. The chess pieces themselves are very sturdy and well built. My only criticism is the building of the box itself. It was quite difficult to see what pieces to use and since the entire box is made mostly of thin plates, it took a lot of time and patience. I would have liked the storage area to be sliding dra
