I was browsing the net like millions of at home people, when this caught my eye. It talks about reasons for clustering raspberry pi  instead of tutorial approach. https://ubuntu.com/blog/building-a-raspberry-pi-cluster-with-microk8s is unique way in my opinion. Please add your thoughts. Is the software good? Have you tried to cluster a raspberry pi? Any good use cases? Clem ...
Pi Day has been and gone for this year but I can't resist doing one more very simple electronics experiment. I'm going to do it quickly, without a great deal of precision, simply to look at the basic ideas involved. If you want to see it done better, and you have a Pi and a reasonable oscilloscope, you could try it for yourself. This is a follow-on from my Pi Day blog, which you can find here Experimenting with a Raspberry Pi GPIO Pin  .   OK, what simple experiment can I do with ...
On this Pi day, towards its ending, I would also like to share some of my experience of working with Raspberry Pi, back in college days. I was on one of the project groups which was assigned to do a portable keyword detection module. The end goal of the project was to develop an offline natural language keyword detector that can be carried around in our bags (later to be made compact in future researches). The background research on possible hardware and software and to suggest a suitable viable ...
With the help of the latest technology, it is now possible to reduce the delay in response required to provide help and support to an emergency scenario such as a disaster, calamity or incident. It drastically reduces the amount of workforce required for carrying out highly sophisticated tasks. An emergency response terrain vehicle has been developed for this purpose which can be controlled and monitored manually.   The rover is a terrain miniature vehicle capable of traversing either manu ...
In this special Pi day, I wish all the community members my warm regards.   For this blog, I would like to write up some brief facts about a project which I developed based on Raspberry Pi. The module used is the Raspberry Pi 3B. The function of the module is to act as a companion computer for an unmanned aerial vehicle (drone), that too developed manually using an S550 kit. Ok, let's roll!!     What the drone basically does is that, it is tasked to follow certain way-points, ...
A simple can easily controlled by a single Arduino. But when the robot ( like the Open Source Outdoor Robot platform JECCbot mini  ) and its task get more complex you need a real computer to do most of the calculations. In most cases this would be a Raspberry Pi. Using only the Raspberry Pi without an additional microcontroller is also no option because the Raspberry Pi is not very good a real time tasks like controlling the motors.   So most robots use a combination of a computer and ...

A good deal about Pi

Posted by clem57 Top Member Mar 15, 2020
  A good video about all things Pi from https://www.exploratorium.edu/pi . ...
It's Pi Day [well, almost: news travels slowly where I am] and I thought I'd add a simple electronic experiment to all the other good stuff that people are doing.   Not all experimenting has to be complicated or requires the use of lots of expensive equipment. I was curious about the GPIO pins on a Pi 3 Model B+, the one that I bought to attempt the PiCasso Design Challenge last year, so I thought I'd have a quick go at measuring one of the basic characteristics myself rather than simply l ...
For quite a while I have been using an I7 laptop running KODI, with the HDMI port connected to my A/V receiver and TV as a HTPC.  This tied up the laptop for only this use because of the power cable for the laptop was run in behind all my furniture.  Plus this laptop has a hardware bug on the motherboard that requires some finagling with the battery and power adaptor in order to get the battery to charge.  So for quite a while I have been searching for an easy replacement that wou ...
https://www.raspberrypi.org/downloads/  has a new feature. You can download an image code for Linux, Windows, and Mac. I tried the Linux version and it works like a charm. I am using Cent distro (Deb based). It allows a simple select the OS like Rasbian or Ubuntu. Other choices are there too. Here is a screenshot after finishing the write/verify.     Give it a spin and see what you think. ...
Just less than 2 weeks go i did my first try on Raspberry Pi 3A+ I put down these items as part of my experience dealing with it   1) Casing with fan i put my raspi 3A+ into this 9 layers acrylic casing with fan. one can reduce the layers to suit his need. For me i remove 1 layer so that it is easier to put in my pioneer600 HAT 2) USB cable i have read that the raspi 3A+ need decent power 2A but  i still face problem powering it up. When it doesn't have enough power, it won't b ...
this is sequel to my first blog last week at GraspIO - IoT for non programmer - Part #1 I have to say after much troubleshooting i got the raspbio to work By right graspio mention it will have dc motor control, but it has not happened yet. hence i use a motor driver to drive the motor instead, and graspio is merely providing control signal to turn on and off   however, i felt it has few drawback -not supported on raspberry pi 3B+ . luckily i manage to grab hold of a raspberry pi 1A t ...
I have given GraspIO a try as it seems to offer easy development via mobile phone and free IoT cloud calls The IO and sensor, plus a little screen makes it useful     i plug it to a raspbeerry pi 3 B+, put in a 8GB microSD card with graspIO image and power it up.   it starts blinking   after what seems like 10 minutes...i not sure why it takes so long. And end up i get this error with the exclamation mark. There is little help or reference i can get from graspio docu ...
I have always wanted to attempt using raspberry pi for industrial project, but i have done it over the last few weeks. Here is the setup of using Raspberry Pi as the main embedded linux device to perform DAQ, analysis and predictive modeling, as well as IoT over MQTT.   Disclaimer Raspberry pi 3A+ and most of the other family members are not meant for industrial use. Despite my application for industrial, it is meant for demo application while concept of application is adoptable, one sh ...
I finally set up my Raspberry Pi 4 the other day, and spent last night and today getting things together in order to do an image recognition project that I've been thinking on. However before I got going on that I wanted a good code editor with some project management features. The pre-installed options seemed lacking. And vi is a fine text editor, but I really wanted a lightweight, general-purpose editor/IDE to work with. I've been using Visual Studio Code on my laptop, and saw that it was poss ...

My Pi Day

Posted by rstone Mar 14, 2020
This was the majority of my Pi Day activities, hanging out with my daughter as she worked on her Kano computer, learning to code the motion sensor. If you're not familiar with the Kano, it's a Pi based entry level computer. It has its flaws, one of which is low memory lockups from time to time, but I got it super cheap on clearance, and she's 6, but  she loves it.   Happy Pi Day! Rick ...

Sony uses Raspberry Pi to speed up its own factories Kevin Edwards has installed around 60 Raspberry Pi's around Sony's factory (Image credit: Sony)   The Raspberry Pi computer is more powerful and versatile than its tiny shell makes it look. Over the years, it moved out of the world of homebrewing to helping massive companies. Last year, Kevin Edwards, who heads engineering at Sony's main manufacturing facility in Pencoed, Wales, took advantage of the Raspberry Pi's cheap price point a ...
A timely post. I went to the store today and saw the panic. I thought, could a Raspberry Pi save the day? I think so, to some extent. Small and inexpensive, Raspberry Pi models are single-board computers (SBCs), which cost as little as $35 for the most recent model is being used in a lot of medical equipment!   They were initially developed as educational devices for teaching the basics of computer science. Still, the small multi-purpose computer has been popular outside its target use ca ...
  Pi Day has come once again, where engineers and makers come together to celebrate the popular SBC. Unfortunately, due to the Coronavirus pandemic, this year’s SXSW expo has been canceled, and with it, the Foundation’s Pi Day festivities. With that said, great projects are still being created using the versatile Pi, and in this roundup, we’ll take a look at some of the notable builds that have been created by the DIY community over the past year.   First and foremost ...
My Rasberry Pi cartoon     Happy Pi Day!   I thought it would be fitting to talk about my Raspberry Pi projects from the very first one all the way up to the most current. And what a stroll down the old memory lane it was.   All the projects are DIY with schematics, parts lists and all the code. If you want to see more about any of them, follow the links. More videos, pictures and stories await you.   I found this journey interesting, nostalgic and inspirational. ...
More than a news it is an announcement.  Maybe not so much time has passed by the end of the Pi Casso Challenge and some members still remember the Art-a-Tronic project and Seven of Nine, the Borg. Almost one year after the project started today I start officially the Art-a-Tronic web site and blog in the self-explaining domain name   we-are-borg.com  On the website, you will find all the episodes of the Art-a-Tronic project and exhibition in videos, as well as a blog with the f ...
I wished to join the Raspberry Pi day activity so I decided that I would combine this with writing my very first own Python programme as well. I recently did an online Python course which had some directed programmes in but I wanted to make up my own unassisted. As I am shortly going out for lunch this had to be very short so I decided on   print("Hello and Happy Pi Day")   Next I needed my Raspberry Pi which is still integrated into my HoloPiBot (HoloPiBot #10 : It Actually Works - ...
A Pi-Day News I hope will be appreciated(by all the Italian language users of the community)  Today, 3,14 2020 I am proud to announce that the new book "Progetti per Maker con Raspberry Pi" has been passed for the press to my publisher Ulrico Hoepli. The book will be available soon on the Italian libraries and on Amazon.

I have been planning to make the ultimate armchair Pi for quite a while. The idea was to create a system that will connect to the TV in the family room to allow leisure and entertainment types of computing activities to be performed from the comfort of a reclining armchair. About a year ago I acquired a refurbished LG 4K TV (55"), so then it was a matter of scrounging a computer to drive it. The criteria for the armchair Pi are: It needs to look like it belongs in the family room (an unpacka ...
The Raspberry Pi being installed for the ultimate hack in the TV series "Mr. Robot." It was a pivotal moment for the whole series... accomplished with a single Raspberry Pi. It was awesome.  (Image credit:  Mr. Robot TV series)   With Pi Day (March 14) just around the corner, engineers and makers are finishing up new projects to celebrate the annual holiday. Usually, the Foundation would commemorate the event at SXSW in Austin, Texas, but the current Coronavirus pandemic forced al ...
  The Raspberry Pi is widely utilized for its project capabilities among engineers and makers alike. It has been used to create everything from robots to remote monitoring devices since its release back in 2012. Not long after, industry managers took note of the tiny board's capabilities and adapted them for use in manufacturing and automation operations, with some using the famous board to build specialized equipment to make those applications more efficient and cost-effective.   On i ...
How Does Pi Deal with Overheating? A reported issue with Raspberry Pi can be overheating, with a resulting loss of performance, when the board is exposed to high temperatures.     All electrical devices are qualified to a specific operating temperature range at which the device will work effectively. The operating temperature depends on the specified function and application of the device; and ranges from a minimum to a maximum ambient temperature at which performance is optimised. ...
