[Jed Hodson] put together a nice little data logger with a Linkit One board at its heart. It’s capable of logging two analog channels and one digital channel which also has PWM capabilities. A GPS is used to get the correct time and a Freetronics OLED display coupled with a shield lets the user view the data in real time.
The data is logged on the Linkit One’s internal storage as a .CSV file, allowing for easy access via a spread sheet program. A LiPo rechargeable battery keeps the electrons flowing and the system will give a warning once the power drops below 20%. Speaking of system – the Linkit One board features an ARM-7 processor and has headers to fit Arduino shields. It’s targeted for wearable and IoT type devices.
Be sure to check out this project if you’re in need of a nice data logger. All code and details of the build are available on [Jed’s] Blog.
Sure, as a very powerful and influential LEGO dictator you’re more than able to make the trains run on time, but how do you make your LEGO citizens realize the benefits of living under your regime? With an OLED LEGO train schedule, of course! [Dan] over at Adafruit put together a great guide to interfacing a very small OLED display to a LEGO setup, perfect for displaying which trains are on schedule and not displaying which trains are heading to a ‘camp.’
The build uses a 96×64 RGB OLED display that is just under an inch in size. After connecting the display to an Arduino, [Dan] crafted a bezel and mounted it inside a LEGO brick wall. Seems like just the thing for the Adafruit LEGO set.
Of course, the tiny Adafruit OLED display can be used for much more than showing the train schedule at a LEGO train station. We imagine this could be put to use in an awesome model train layout or even a small plastic security checkpoint.
