Inspiration struck me the other day and I’ve come up with a new project.  I’m going to use a Raspberry PI for it, since I am such a fan of Linux, to make a remote control for the EV3.  It’s going to use an IMU (Inertial Measurement Unit) to control the WiFi connected robot.  I ordered the list of component ...

Mirobot is a very cool open source robotics kit that’s completely open source and very affordable.  When I was contacted by Ben Pirt, the man behind this project, I was admittedly a little skeptical about yet another robotics system.  However, this robotics kit seems very nice and sports some very cool features: Super easy to build, it takes just two ...

One of my readers, Elias Barcia, mailed me back in May 2013 to ask for some input for a university project he was working on: make the three generations of MINDSTORMS, RCX, NXT and EV3 communicate with eachother.  I gave him some feedback and pointers and some time passed.  I had all but forgotten about it until he mailed me ...

Virtual Router Manager In an earlier article, I had written about how to allow your EV3 to connect to your laptop (or desktop) with a shared WiFi network, using a feature called Hosted Network.  It essentially turns your computer into an Access Point (AP).  Since then I’ve had a bit more experience with it and I’ve found a very easy ...

If you’re like me, and you do a fair bit of playing around with Wi-Fi sensors, you may find that you don’t always want to connect your contraption directly to your home network.  There are two alternatives, setup a second wireless router, or, if you’re using Windows 7 or 8, you can use the built-in hostednetwork feature.  What’s hostednetwork, you ...

Splunk is an enterprise-class machine data gathering and analysis tool, capable of consuming 100s of gigabytes of machine generated data and turning it into arbitrarily searchable data and presenting it with fancy reports and graphs.  I’ve used Splunk in the past for a project and another time to do post-mortem analysis of a hacked webserver. Since I was working on ...

What is SNMP? When I got my NXT2WIFI sensor from Daniele I was quite sure what I wanted to make with it:  an SNMP agent.  What is an SNMP agent, you say?  SNMP, short for Simple Network Management Protocol, is a protocol that, as you may have guessed by now, a protocol that can be used for monitoring and configuring ...

‘s robot! Yes, that’s right, you can reach out and play with Laurens’ Alpha Rex over the Big Interwebs!  He made a cool looking web interface for it and allows you check out what it’s doing via a webcam! I did something similar a while back but not nearly as cool looking as this!  Go check it out before it’s ...

Daniele Benedettelli is looking for help, your help!  He has developed a new WiFi sensor for the NXT called the NXT2WIFI. So what is the NXT2WIFI?  Obviously it’s a WiFi sensor for the NXT it’s a bit more than that.  It also has a web server built into it that allows you to create a web interface right on the ...

New Kid on the WiFiBlock A new player has entered the arena of WiFi sensors.  A French company by the name of HumaRobotics has developed a new WiFI sensor for the NXT, the WiFiBlock.  This sensor is a bit different from existing sensors in that it uses I2C, not RS485 to communicate with the NXT. It runs on 3xAA batteries ...
