  • Wilcoxon PC420V vibration sensor with a Raspberry Pi 5

    Wilcoxon PC420V vibration sensor with a Raspberry Pi 5

    Vibration analysis is important for any industrial process, as it provides us with a lot of information about the mechanical state of the machines we use. It also allows us to use their signals as interlocks in PLC programming, etc. Therefore, one of…

  • Min and Max bulk samples from Data Acquisition Board for Pi Pico with C++ STL

    shabaz designed a Data Acquisition Board for Pi Pico . In the first post , I used it in continuous sample mode. I took 1 second worth of samples, in 860 samples per second mode. In this post, I use C++ STL constructs to find the minimum and maximum…

  • Converting bulk samples from Data Acquisition Board for Pi Pico with C++ STL

    shabaz designed a Data Acquisition Board for Pi Pico . In the first post , I used it in continuous sample mode. I took 1 second worth of samples, in 860 samples per second mode. In the second blog , I averaged those samples, using C++ STL constructs.…
  • Average bulk samples from Data Acquisition Board for Pi Pico with C++ STL

    Average bulk samples from Data Acquisition Board for Pi Pico with C++ STL

    shabaz designed a Data Acquisition Board for Pi Pico . In the previous post , I used it in continuous sample mode. I took 1 second worth of samples, in 860 samples per second mode. In this post, I average those samples; using C++ STL constructs. I'm…
  • Continuous sampling with the Data Acquisition Board for Pi Pico

    Continuous sampling with the Data Acquisition Board for Pi Pico

    shabaz designed a Data Acquisition Board for Pi Pico . In this post, I'm using it in continuous sample mode. Goal: get 1 second worth of samples, in 860 samples per second mode. There are several options to trigger the reading of the samples. You could…
  • Measure the Analogue Front-end of Data Acquisition Board for Pi Pico

    Measure the Analogue Front-end of Data Acquisition Board for Pi Pico

    shabaz designed a Data Acquisition Board ( DAB ) for the Pico: Data Acquisition Board for Pi Pico . In this post, I'll measure the analogue front-end, and show how it behaves within its +- 4V range. I've attached probes to the main points of interest…

    Table of Contents Introduction Circuit Diagram Board Assembly Testing It Known Issues Next Steps Introduction Data acquisition is pretty essential! However, it proved surprisingly difficult to find a plug-on analog-to-digital (ADC…

  • Creating a Pi Pico based High-Resolution Measurement Instrument

    This blog post contains at least two topics, both (hopefully) interesting. One topic concerns how to code new functionality into an exciting open source project called the Pico SCPI labTool . The end result discussed here provides four analog voltage…

  • Raspberry PI 2 - Fun with I2C DACs and ADC's

    In this video we go beyond the setup of the I2C, SPI and OneWire interfaces on the PI2 and look at how to integrate some common I2C analogue IO devices, specifically the following DAC8571 Quad 16bit DAC:- http://www.ti.com/lit/ds/symlink/dac8574.p...

  • Grow Organic With Smart Garden - ON Semiconductor RSL10-SENSE-GEVK

    Introduction: Now a day mostly mass produced vegetables and fruits are GMOs, contaminated with dangerous chemical pesticides and traces of chemical fertilizers. And mostly products labeled as organic, are not 100% organic. So the best and most cost…

  • OLED 0.96" Display Interfacing with ON Semiconductor RSL10-SENSE-GEVK

    Being an ultra low power device OLED display is perfect combo for RSL10 to display necessary information. C version of well know U8G2 library is used to interface this 0.96" OLED display with On-Semi RSL10-Sense-Gevk board. // U8G2 display structure static…

  • ADS1115 (16-Bit ADC) Interfacing with ON Semiconductor RSL10-SENSE-GEVK

    ADS1115 C library and main.c is attached below OnSemi RSL-10 module has 4 ADC inputs but on RSL10-Sense-GEVK only one ADC input is available. Due to the availability of only 1 ADC pin user has only 2 options either use this single analog input with any…

  • Path to Programmable - Project update

    This is an update on where my project is at. My initial intent was to rebuild a line follower that I did back like 8 years ago; but using the MiniZed. The board is very well suited for this application - the PL (FPGA) can do all the grunt work of reading…

  • Smart Range Hood - Intro to the control system - DHT22 (et al) [Buzzer, Light control] - Pi Chef Challenge - Blog post #7

    My Goal - Make a sort of "hat" thing that sits above the stove to bring the stinky stinks to the outside world (i.e. a smart range hood which can run itself, text the home owners, summon the husband for dinner with images of dinner, and do other cool…

  • Smart Range Hood - Can I have a bigger slice of breadboard? - Pi Chef Challenge blog #6

    The goal - have a range hood which is cooler than yours See blog post #1 for links to all the posts. In this installment, I cover hooking up basically all the electronic components. I also start to get into some of the software work that I've done so…
