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, [...]
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 [...]
Last Thursday Laurens Valk came over to chat and play. We thought it would be fun to try and do something with our AnyWays, Laurens had brought his with him. We thought it would be fun to make one follow the other. We’d use the HT IR Ball as a [...]
Today I’ve been quite busy programming a more generic framework for using buttons, strings and multiple windows on the NXT. Things like button pressing is now handled centrally, as well as rendering the windows and the buttons in their current state. It’s starting to take shape now and it’s not [...]
I thought it would be kind of fun to modify some of my program to make use of the Mindsensors TouchPanel sensor. Having buttons on the screen would make it a lot more intuitive to use. So here’s a first short video of a 3D button that you can press [...]
This is possibly the most annoying musical instrument in the world. My dogs weren’t all that impressed with it either. It’s like the Theremin from hell without any of the redeeming features. It is to music as ketchup is to pasta sauce. So it is not without some pride that [...]
…So I built you this LEGO contraption so you don’t need to hold that mobile phone anymore. Can you believe that my wife actually sat there patiently while I built this thing next to her? She was complaining about her arms getting sore from holding up her mobile phone so [...]
After the initial post about my thermal imaging system using the Dexter Industries Thermal Infrared Sensor, I made some improvements with both the speed and accuracy of the whole thing. I made the sensor sampling interval time based, rather than encoder value based. This proved to be a lot better [...]
Sometimes an idea comes into existence and you wonder why the heck nobody else came up with it. My good friend Laurens Valk was working on a robot for one of his classes and asked me if there was a way to PWM the pins on the sensor port, dig0 [...]
The NXT webserver has been up for a few days now and it’s really cool to see so many people logging into it to make the motor move. When I created it, I had no idea that it was going to be used as much as it has been. I’ve [...]
