DSC_0830It’s hard to deny that “STEM” is the new buzzword in education. We need more STEM education! With the focus on this buzzword, schools are scrambling to figure out how to put STEM classes into their curriculum.

Robotics for me was the hook; it got me to explore, to question, to discover.

One of the most common ways schools are “adding STEM” is introducing robotics classes. I have seen countless schools that have introduced VEX IQ or LEGO MINDSTORMS as a way to address the need for STEM. These classes are “teaching” robotics, which as an engineer I don’t really understand.

Remember that LEGO GoPro Gyro Stabilizer I showed in my Make Faires post? If not, check out the picture below!

Now you can 3D print that same GoPro to Technic Mount! I have posted it on Thingiverse. Go Check it out! All you need is 1 EV3, 3 Gyros, 3 Motors and an afternoon to make your own! Have fun!

September was a busy month for me! The highlights were both Maker Faire Orlando at the Orlando Science Center and World Maker Faire at the New York Hall of Science. You might have noticed a hint of what I have been up to over the past weeks. This post will be pretty heavy when it comes to pictures to help share the AWESOME that is the maker movement.

Never heard of Maker Faire? A Maker Faire is an event put on in conjunction with Make: magazine to celebrate “makers”. What is a maker? Well that is a little more difficult to understand. At its core a maker is someone who makes things. There is no age requirement to be a maker. There are lots of different types of makers. Some are ROBOT MAK3RS or people that make with LEGO MINDSTORMS. However that is hardly an official category. You might make robots, cars, giant flaming robot sculptures, paper models, apps, clothes. Making can use a range of materials from 3D printing to LEGO to metal/wood to fabric. Making is a form of expression and hands-on learning.

You can checkout coverage of the LEGO MINDSTORMS Booth, including some of my bots at The NXT Step!

I was working on my Icom 706MKII a little while ago. I had gotten a new Heil mic for my rig earlier this summer and needed to tweak the ALC on the radio. When I was telling my brother, Tony (KD8RTT), about it, he asked me to make a video to help viewers of his channel. Check out the video above if you’re having mic issues with your Icom 706!

About 9 months ago, FATCATLAB posted a Kickstarter for an EV3 cape for the BeagleBone Black, an open source embedded Linux computer created by Texas Instruments. Their product was called the EVB. It was successfully funded and kits shipped out a few months ago. I received mine  a little while back. Generally I prefer using an EV3 brick, but I have loaned a bunch of my EV3s out to a local school district for training for FIRST LEGO League as they were awaiting their shipment of EV3s from LEGO Education.

See my thoughts (that didn’t make the video) after the break. (more…)

Panda APRSI know I have been bad at posting projects recently, but here is one I have done a few times now that is super easy to reproduce. With the super cheap embedded Linux platforms (Raspi, Beaglebone, etc.) and cheap TV dongles, it is really easy to make your own APRS iGate, just like the one in the photo above. This tutorial will give you the steps to get going with an APRS iGate. What is APRS you ask?

APRS stands for Automatic Packet Reporting System. It is a 1200 baud RF (mainly ham radio) packet system commonly used to record telemetry. Sometimes it is fun to log a trip or track a robot. APRS is a great tool for these sorts of problems. In the USA, APRS is commonly used on 144.39 MHz. It can be used between radios directly or can be used to log on the internet (via websites such as APRS.fi)  via an internet gateway or iGate.

By now you have likely seen the picture above or my original post. In September I took these guys to World Maker Faire in New York City. These bots were a huge hit, bringing Minecraft to life! Since the original video, I have received one question to no end: does it explode? My answer? See for yourself!

My latest video takes captures some of my favorite moments from World Maker Faire. The event was a team effort bringing employees from LEGO as well as the greater LEGO MINDSTORMS Community together. There is so much overlap between the MINDSTORMS Community and the Maker Community! It was great to share ideas and projects with others!

These Creep3rs will be touring for a bit. My good friend Marc-Andre has one up in Canada. In addition, a couple of these guys will be traveling with me to Brickworld Tampa in a couple weeks!

What are you up to this weekend? Well, I will be in New York City for the World Maker Faire and I am bringing this guy along. Check out the video to see what I made!

Fans of Minecraft are sure to recognize him. This is just a teaser video of what you might see if you stop by the LEGO MINDSTORMS booth. The total project took just under a month and used well over 1000 LEGO Technic parts. Checkout how I am a #RobotMak3r!

It is no secret that I bring LEGO robots all over the country. When I travel I usually bring a stock of EV3 flyers and stickers. What is a secret is that I used to spend countless hours putting a sheet of stickers in each flyer booklet.

With EV3, I thought I might go about optimizing this process. FLY3R is a LEGO MINDSTORMS EV3 bot that will put a sheet of stickers into a flyer booklet. The robot is simple: walk up, press button, receive flyer + stickers. Check out the video to see it in action!

The icing on the cake is that this entire bot can be constructed out of a single EV3 retail kit. Call it a “one kit wonder”! Over the next few days I will be working on some building instructions as I have a few people already asking to build the bot. The code is posted on the Downloads page of my blog. You can open it with the EV3 retail software. If you’re interested in building the bot, be sure to leave a comment below so you get notification of when the instructions are posted.

Port layout:
Motor A: Medium Motor – Sticker stuffing wheels
Motor B: Lare Motor – Flyer opening arm
Motor C: Lare Motor- Flyer opening roller wheels
Motor D: Open
Sensor 1: Button – Start stuffing flyers
Sensor 2: Open
Sensor 3: Color – Flyers present/in correct orienttion
Sensor 4: IR Distance – Detecting when the flyer is open

This is not my first post about FIRST, and it certainly wont be my last. In case you missed it, I was a mentor/coach for FIRST Robotics Competition Team 5145, WolfBotics. I have to give a shout-out to NASA here as they were our title sponsor and without them our team would not exist. As a coach/mentor, I helped the students design, build, test, and compete with a robot. At the Orlando Regional, WolfBotics won the Rookie All Star Award and was invited to the FIRST World Championship in St. Louis, Missouri. As a boy from the Midwest (I am from Ohio and did my undergrad in Indiana), I couldn’t wait to share some of the sights I grew up with. Naturally the St. Louis Arch and some of the amazing food. (Although they are yet to try Skyline Chilli.)

The first video above shows our pit setup on Wednesday night. It took a few hours, but I have it condensed to about 20 seconds for your enjoyment. Below is the trip from Gainesville, Florida to St. Louis, Missouri. We had a motor coach to drive us (thank goodness!) for the 13 hour drive.

Now everyone wants to know what the robot looked like, so below is a picture of our bot. I am super proud to say that it was all design, built, programmed, and operated by the students. When things went wrong, the team sprang into action and did an amazing job of fixing the bot. It was an excellent learning experience and I am looking for ward to the next season!
