For an T&M Learning, Start with these tutors of NI. Like Analog Amplifier Circuits and Analog RC Filters. RF and Microwave Fundamentals if you want to be good at Communication Technologies. Sensor, DAQ and Instrument Fundamentals for Industrial Automation Learning.
National Instruments Wi-Fi DAQ devices combine IEEE 802.11 wireless or Ethernet communication, direct sensor connectivity, and the flexibility of NI LabVIEW software for remote monitoring and control of electrical, physical, mechanical, and acoustical signals.
NI Wi-Fi DAQ features and to learn how you can simplify wireless remote measurements without compromising on the security or performance of a cabled data acquisition solution.
You can learn about every niche/domain in Electronic Technologies. You also need to Specialize in a niche which resonates within you. The skill sets need to be broad, in case you find less opportunities in the specialization you have. This keeps changing all the time.
Any Tablet with an external Hardware can make a nice Instrument. The professional part lies in that external hardware and usability of the software or app. Windows Virtual Instrumentation are well known. Things like USB Scope and Data Loggers have been there for decades.
Now we have Android in which an Open Source product can be developed. The Open Source is both in Hardware and Software.
See a android virtual instrument – OsciPrime is an Open Source Android high speed data acquisition hardware platform and Android oscilloscope application.
Virtual Instruments for Android has a nice future in Industrial, Automotive and Measurement areas. You could start by Interfacing with Bluetooth, USB and then move to IoT and WSN. Android OPC UA SCADA and Client
TeslaSCADA is a SCADA for accessing production and process data through smart phones and other Android devices, using the industrial communication standard – OPC Unified Architecture (UA).
These were some questions i got a few years back…
1 – If i had to create a crude “Lux Meter” and “db Meter” using the built-in camera and microphone on a Android Device – How would i Calibrate it ?
2 – Is there a Component(software) for Android to interlace with a Arduino Device as an external interface, This will help us make a DMM/Scope or even a Entire Lab Test bench centered around a Tablet and a Plug-in Mini Instrument Rack.
Both Sound or db Meters and Lux or Light Level Meters are in the Google Play nut need calibration. All These Instrument Needs a USB/Bluetooth Sensors.
Add Bluetooth you can carry your Tablet away from the instrument probing the DUT. (Device under Test)
Utility of Testing and Troubleshooting Tools : The first thing in Electrical testing is the Continuity Tester, Then we use the Neon Mains Screwdriver, Then we need an Voltmeter or an Ammeter. In electronics we need a OhmMeter and LCR meter too.
Many times we cannot carry big or expensive test instruments to the field, so we have to have a troubleshooting tool kit. Continuity testers, Logic Probes, DMM, Clamp Meters etc..
It also is sometimes required to build a quick jig or fixture with electronics to troubleshoot, simulate a problem or to test the reliability or aging of components and systems. Here you need to be cost effective, fast and innovative; and build a simple system with available, affordable or procurable resources. Hence a bit of circuit design, firmware and software are essential skills for production engineering.
The Intersil ICL7106 and ICL7107 are high performance, low power, 31/2 digit A/D converters. Included are seven segment decoders, display drivers, a reference, and a clock. The ICL7106 is designed to interface with a liquid crystal display (LCD) and includes a multiplexed backplane drive; the ICL7107 will directly drive an instrument size light emitting diode (LED) display.
This is one of the first mixed CMOS IC, I used it after studying Intersil CMOS Hot Ideas Book. It is also the most widely used Display chip. Many Millions of Instruments are built using this chip both in Instrumentation and Industrial Automation. The ICL7106 was most popular in Hand Held DMM’s and Clamp Meters as it used to drive a LCD Display. ICL7109 was to interface with Digital Comparators and Microprocessors
Ever wanted to develop a Professional High Speed DAQ or a Storage Oscilloscope or even a High Speed Communications grade Logic Analyzer. Here is a front end Analog Mixed Chip with Eval Board.
You could make a High Speed Test Instrument and probably build a tablet app front end. How would a 200 M Hz Oscilloscope look on you 10 inch tablet. You will float in the clouds. – delabs
The DRS chip is a full custom Integrated Circuit developed at PSI, Switzerland. It contains a switched capacitor array (SCA) with 1024 cells, capable of digitizing eight analog signals with high speed (6 GSPS) and high accuracy (11.5 bit SNR) on a single chip.
By using channel cascading, we can configure this board with 2048 bins for each channel at the expense of a lower analog bandwidth of about 500 MHz. The on-board comparators enables the board to do a self-triggering on a programmed level of any of the input channels or logical combination of channels, much like an oscilloscope.
Highlights of Board with One DRS4 chip
Four 50-Ohm terminated input channels with SMA connectors
Active input buffers which result in an analog bandwidth of 700 MHz (-3dB).
One AD9245 ADC to digitize signals from the DRS4 chip
One Xilinx Spartan 3 FPGA for readout control
A 16-bit DAC to generate all on-board control voltages
A serial EEPROM containing serial number and calibration information
Internal trigger with user-defined thresholds on any of the four channes.
CheapStat, an inexpensive (<$80), open-source (software and hardware), hand-held potentiostat that can be constructed by anyone who is proficient at assembling circuits. This device supports a number of potential waveforms necessary to perform cyclic, square wave, linear sweep and anodic stripping voltammetry.
The device supports cyclic, square wave, linear sweep and stripping voltammetry over the potential range ?990to +990 mV and over frequencies from 1 to 1000 Hz. The device supports a range of environmental, food and drug quality control, and educational applications. The reverse of the circuit board supports a three-line LCD display and a joystick, which is used to select an experiment protocol, change its parameters (frequency, starting voltage, end voltage, scan rate), and initiate the experiment.
The device’s schematics, parts lists, circuit board layout files, sample experiments, and detailed assembly instructions are available in the supporting information and are released under an open hardware license.
