We just finished our first tutorial! This tutorial describes everything you need to know to connect a K-Type thermocouple to an ARDUINO and to the Evolved Horizon application. Start sampling and storing temperature data within minutes. The tutorial is completly stand-alone, and it even includes a companion-script for easy setup!
A smaller update to Evolved Horizon has been released, focusing on GUI performance, and DPI-awareness. All of the GUI components should now correclty scale to OS-scaling on smaller or high-resolution screens in Windows.
Added FFT-like time->frequency domain plot in the analytical interface. Gain insights of hidden frequencies in your data is just a matter of choosing the right plot. Works for non-evenly distributed using the Lomb-Scargle technique, see screen-shot below.
We just finished Evolved Horizon 1.11, this time we focused on the hardware and added support for the ARDUINO DUE as well as the digital input. As a bonus, you get the Resample DSP 🙂 Read more in the release notes.
We are proud to release v. 1.10 of Evolved Horizon, with many interesting new features, see change-log below.
Release Notes for Evolved Horizon v.1.10 (“Curie”)
Added New Analysis plot type: “Box plot”
The box-and-whisker plot may be used to visualize the distribution of data through its quartiles. Use the boxplot for easy overview of the distribution of your data per channel. All the boxes are notched at the D50 (median); two medians are significantly different at the 5% significance level if their intervals (notches) do not overlap. Outliers are marked as red. See more at https://en.wikipedia.org/wiki/Box_plot.
Added “Show Previous” and “Show Original” checkboxes in Analyze.
Extremely useful feature to see the effect the DSP has on your data. The previous is the last applied DSP data (or original if number of DSPs are 1). The original is the data without any DSP. The current DSP overlays the previous/original who is rendered in a grayish color.
Incidentally, all the DSP applied is only temporary…your data is not altered. In fact, to ensure data integrity, you may not alter it post-I/O!
Various Icon fixes in splash screen and other GUIs
Added booter_log.txt in Launcher->Configs->Logs. Changed colors of the log to be white/black for background/text. Added “Open in OS” of all logs.
Toned the color of the “selected”-background color of the image-text button.
Stardots is excited to announce a collaboration with Uppsala University and the Department of Engineering Sciences, Microsystems Technology division. Stardots, distinguished scientists and students will evaluate and develop upcoming Evolved Horizon releases.
Stardots is honored to be nominated for the Bona Postulata 2018 award! The nomination goes out to companies with large potential for growth in Uppsala county. For more information and to see previous winners click on the link below: https://bonapostulata.se/
Normalize your data for better comparison, and easier viewing. Use any value for lower and upper limits. Perfect in conjunction with integration for better insights, without data drowning.
Outlier removal DSP
Filter unwanted outlier data, using moving-median or moving-mean without smoothing the data too much. Powerful when data contains artifacts. Choose outlier fill methods (Linear, nearest, splines) and threshold values for maximum flexibility to your data-set.
Added USB port selection on the firmware uploader. Some devices (e.g., MEGA) requires a specific USB port for uploading. Use “Auto” for complete scan. Please unplug all devices except the device scheduled for firmware upload.
Doubled the buffer size and added many more buffer configurations in the firmware. Use long and narrow buffer for few channels but high I/O rate. Use short but wide for many channels and lower (requested) I/O rate. OBS: the actual I/O rate is not only determined by the buffers but also the reading of the pins etc.
See an analysis of two K-Type thermo-couple experiments that seems to have some sensor glitches; possibly some sensor-wire problem. Lets try to remove those to not obfuscate the analysis:
Fixed the lag-race associated with a session that has a I/O-rate set at higher Hz than the hardware can handle. Warning: a diff between actual and requested I/O-rate will not be easily noticed.
Fixed basic DPI-awareness for OS-scaled high-resolution screens… All elements (including graphs) are DPI-aware except some data- and setting-tables.
Rewrote the flush/acquire routine of the session to be more responsive to trigger commands and less taxing to the USB communication. Evolved Horizon 1.09 requires Arduino Firmware +1.4.x.y
Improved buffer memory footprint of the Arduino. More memory == more I/O rates. potentially more sensors. 🙂
Made the graphical user interface engine more responsive (hoover of buttons etc.)
Fixed a bug in the numerical calculation DSP (static time stamps no longer assumed)
Stardots is pleased to announce that we are now supporting the lovely Adafruit MAX31855 and MAX31865 breakout boards for K-type thermocouples and PT100/1000 elements. Specify the pin location and you are ready for high-speed, high range, or high precision, temperature readings. Any combination of analog input, PT100 or K-type thermocouple is allowed; turn your Arduino into a sensor powerhouse within minutes!
Evolved Horizon lets you combine and apply custom smooth-, scale- and transform-DSPs to your I/O data in matter of seconds, for fast data insights. See example below; first we smoothed (twice) the data using a simple symmetric moving mean with a window of 10 points. Then we scaled the data with both respect of the data and time, using an arbitrary function. Then we performed numerical integration. All DSPs are combined simple by clicking a button. Export the final plot and its data to .xlsx or .csv format, for your final analysis or further export/storage.
