#cNMR: #OpenSource compact time-domain hydrogen (1H) #NMR system for field deployment:
-based on a 0.5 T permanent magnet
-emphasizes relaxation times rather than chemical shifts, enabling material property analysis without large magnets or complex spectral processing
-requires #LabVIEW

Rainy day in EN52 Chicagoland - time to setup and test a Mini-Circuits ZX47-55 RF detector module to see if working or not. Measured DC Out vs 100 MHz RF level In and DC Out at -20dBm In while sweeping from 0.1 to 6 GHz. Result: It works as a RF detector module but DC output is not easy to use (want dBm, got neg-slope DC mV instead). Might make a LabVIEW program to display/chart dBm with Digilent AD3, or maybe write code for a standalone Arduino w/ display showing dBm… #RF #LabVIEW #Arduino
I need to get ridge of my 36 years old #Toshiba T1600 laptop and a couple of #C++ #Qt #labview #programming books which I probably never read. Anyone interested?
To this day I'm convinced that by far the best way to do concurrent programming with #threads (beyond graphical programming languages like #Labview, where concurrency is natural) is that used by #Tcl
In other words each thread is created with its own sub-interpreter. Each has its own context, not shared. Information is passed by messaging (which the receiver receives in their own event loop). Channels moved (not shared) explicitly.
This massively reduces race conditions and other nasties.

So the background: we have a optical spectroscopy lab, with several instruments doing similar stuff and producing similar data. Each instrument has components and the whole setup is controlled by PC. Normally, one would use #labview for this kind of work.
But I do not. Why we would use gargantuan multi-gigabyte proprietary commercial program, when we could have the same functionality with few hundreds lines of open-source code, right? 😀
There are some reasons why I "don't like" LabView:

Why is everybody making a HyperCard cline, and nobody is making a LabVIEW clone? Not that I don’t love HyperCard, but LabVIEW is cool too.
Виртуальная лаборатория робототехники или Как мы выбирали подходящее ПО
Вступление Так получилось что мы группа студентов и преподавателей заинтересованных в создании имитационных виртуальных лабораторий, в которых студенты могут без особых углубленных знаний попробовать поуправлять квадрокоптером, конвейером или другими интересными моделями. Ведь не всегда есть возможность потренироваться на реальных физических лабораториях. Нужны: место (деньги), оборудование (деньги) и время (тоже деньги). Следовательно придется смотреть в сторону виртуальных моделей. Мы искали удобную среду для создания таких моделей и вот до чего дошли (обозреваем ниже). Немного истории : факультет электромеханики (ныне переименован в Мехатроники и Автоматизации) НГТУ создавался в 50-х, чтобы готовить специалистов по разработке и производству электродвигателей, электрогенераторов e.t.c. Позднее факультет оброс кафедрами смежных направлений а в конце 2020-х открыл направление Робототехники. Профиль ФГОС и 70% предметов оставили прежними. Как и педсостав. В результате получили выпускников которые: умеют подобрать двигатели для круглого квадрокоптера в вакууме (и не только подобрать, но и спроектировать с нуля или пересчитать/перемотать); умеют настроить регуляторы для этого пепелаца; знают как рассчитать мощность и КПД. А вот о том, как программировать автопилот — только «имеют представление». В принципе такая заточка имеет право на жизнь если разрабатывать не роботов-доставщиков, а промышленные роботизированные ячейки.
Having moved from developing industrial measurement systems with #LabVIEW to #rustlang, @wiresmith found the tool ecosystem to be one of the major benefits.
In this talk, he’ll run through the tools he's using to produce reliable & performant industrial measurement systems for clients. #MemorySafety #OxidizeConf

As part of NI’s push for “#LabVIEW everywhere” in the mid 90s, the development environment was ported to a wide variety of platforms, including several video game consoles.
These console versions were never officially released, though internal beta copies are rumored to exist.

Kenne die vom Studium.... #LabView
@scarletfire I'm probably going to be yelled at by saying that I really like Labview. Used it to tune my experimental setup with the Alphatrack midi mixer. Thanks @ct_Magazin for a short product info in some article back in 2007 (I think..?). Ah the times....

Wow, NI(National Instruments) *really* raised their prices this year-- our quote for 7 licenses (5 full and 2 pro) of #LabVIEW went up by 60%?!?!
Well, guess what? This will just cause us to ACCELERATE our conversion from LabVIEW to #Python even quicker. I guess the new owners (Emerson?) don't really care-- if anything, they probably have very little interest in LabVIEW in a smaller R&D setting...

The reroute nodes work pretty well in #Blender3D. My first experience with node based systems was in #LabVIEW. Heh, knob-and-tube nodes!
Made a module that takes in several values and uses them to drive a phase angle output. Want to use this to animate three phase equipment, such as motors, generators, transformers, #rectifiers and #inverters. Hope to have a two-pole motor stator animation soon.
