Convert PNG to Transparent PNG

Posted on September 27, 2020 by LV_TS_Test_Engineer_3000_VI

Needed to convert a PNG image to Transparent Background PNG

Notes

•Presentation on using Microsoft’s Paint3d to make a previous save png that was not transparent to transparent without using other tools.

•MS Paint and  “Paint 3D” used in this presentation  are Microsoft products.

•Presentation shown to spark ideas of use and may not be the only way to do it.

•This presentation is not connected to or endorsed by any company.

•Use at your own risk.

•For this simple example it would be easier to create the transparent image inside MS Paint 3D to begin with using A Transparent Cavas and the 2D shapes.

•Future wishes: Magic tool option that would just take a unique color with tolerance and remove it. (that would have been less steps).

LV Waveform Image Hand drawn to XY Graph

Posted on September 4, 2020 by LV_TS_Test_Engineer_3000_VI

Using a hand drawn image with specific color for each element ( Wavefrom Black, X axis -Green, and Y axis-Red convert it to XY Graph.

Below is the presentation for this post using MS PowerPoint (r)

Notes

• Showing how to take a hand drawn image to XY Graph

• Technologies used  Image file to Picture (PNG) and Picture to 2D map.

• Presentation shown to spark ideas of use.

• (used LV2019 Base version-most fitting function are not in base so had to use mean for x and y axis)

LV Multiple Process Vi with SubPanel

Posted on August 28, 2020 by LV_TS_Test_Engineer_3000_VI

Open multiple instants of a Process VI and showing it in a SubPanel.

Messaging via the unique queue of the Process and the Main queue.

Notes

•Showing LabVIEW® running on vi  multiple times (Clone) and SubPanel to prevent multiple vi open all over the screen (managers don’t like that neither the end user)

•Technologies Vi Ref, VI server , Sub Panel, QUEUES.

•Presentation shown to spark ideas of use. (used LV2019)

•LabVIEW® is a National Instruments (NI) product

•This presentation is not connected to or endorsed by any company

•Use at your own risk.

•This project was an example to spark ideas and should not be consider complete.

•Note: Keep an eye on the clone number , it will help when working with Vi Refs to prevent Vi refences left in memory and not  properly discarded.

•Always test out multiple stopping methods during development (ie Stop Process button, Stop on Process vi, Exit, and Application close. )

•The example project was started using NI® LabVIEW Queued State Machine project template

UUT Class and Messages

Classes of LabVIEW(r) Actor Framework Example

Short Video (about 31 seconds)

Notes

Notes

•Showing parts of an example Temp cycle sim, UUT test sim ,Power supply sim using the LabVIEW® Actor Framework Project template as a starting point.

•Technologies used Classes, Object Orientated Programming(OOP), Encapsulation, Inheritance, Override, Dynamic Dispatch Actors, User Events.

•Presentation shown to spark ideas of use. (used LV2019)

•Use at your own risk.

•One more note, which others have stated and applies to me also , Don’t spend your projects budget trying to look into every BASE Method of Actor Framework to figure how it works. Think top level (Actors, Methods, Messaging, User Events and Helper (Event Loop) , If new with AFW start with the NI Actor Framework Project template (2019) as I did.

3.7vdc 18650 type Low Voltage dropout module

Posted on February 11, 2020 by LV_TS_Test_Engineer_3000_VI

Need to make a low voltage dropout module to protect the battery from going to low when driving a load.

The charging module was allowing the voltage to go to low (about 2.5vdc) which i did not want.

A pushbutton start the voltage to the 3.7 to 5v module.

The P mosfet turns off when the battery voltage drop below the vdrop set voltage(3.4vdc) which in this case is set by voltage divider using the 5v out tap as a reference.
