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.
Just released Evolved Horizon 1.07, packed with many new analytical tools, see screen-shots and change log below. Just restart the application and receive the upgrade. We also built a new Window installer, for easier installation.
Export current plot to Excel/.csv file
Export database entries (including all data)
Added Advanced panel
Colormap changer – Not happy with our default colors? Change them! :-). Added Earth (parula), Spectra (jet), Space (cool) and Sun (hot). (Matlab equivalence)
New plot-type “Histogram”
DSP selector: add, combine and remove loaded DSP and visualize directly onto screen.
New Class “DSP” – digital signal processing
Perform analysis of I/O data using various filters etc.
DSP Module: Moving Statistics Smoothing
Smooth noisy data using moving mean and moving medians. Configure symmetric and asymmetric window widths.Perform moving sum, product, minimum, maximum, standard deviation, and variance statistics.
DSP Module: Integral Calculus
Perform numerical integral calculations using the trapezoid method.
Added limited hardware support for the Arduino MEGA 2560
Added limited hardware support for the Arduino DUE (in the form of .bin file. Upload is done manually using appropriate uploader.)
“Stardots” derives from stars and space, as the representation of exploration and discovery, and connecting the dots as an illustrative of gained insight. The by-line articulate our core mission: Let data be the our guiding star in the course of development.
Evolved Horizon™ is the name of the now available product that hopefully evolve the horizon of the data from experimental set-ups including sensors.
