Hi all! I live in Silverton, CO (that is the joke) USA
New to Raspberry Pi but have been programming for a while. I wrote my first “Hello World” on a ‘desk computer’. It was the size of a desk, had drum memory and paper tape. Early on lots of assembly and bit level stuff. Now not so much.
Current personal project uses an Arduino MAGA with a Motor Shield plus two custom boards to get to the GPIO pins. Also includes a Raspberry Pi 4B with a Servo HAT and 3 Servo Bonnets topped with (I hope) 2 Unicorn HD HATs. I also use 12 of the GPIO pins on the Pi to power LEDs.
Hello all ,I am OldGit,been interested in Electronic on a hobby front since my teens (Late1960s) ,use to build valve amps,nothing great but they worked(sometimes).since retired from work have more time ,i have about six PIs two are zero w, the 3B+,4B/4gb,3A,they ll got they little tasks ,one zero,use for Pimoroni s Phat Dac it works brilliant,Anyway i not the best coder ( probably the worlds worst ha ha ) seriously not good at all but slowly getting there ,I glad i found this Forum, find it best helpful .
hopefully we grow together OldGit
welcome,I class myself as a OldGit , or Old Coot to ,and if the 64 at the end is age ,then i got a few years on yaaa if it year ,i still got a few on yaaaa. I dont code either ,so i use all the help i can get to make my toys work, thats one of the main reasons i buy most of my collection from Pimoroni ,so i will post a link to a place i spend a bunch of my time to get the cvode i need ,good luck and enjoy, https://github.com/pimoroni
Hi, I’m a complete novice with the Raspberry. I’ve just purchased a Raspberry Pi4 which I intend to use in conjunction with Pi Sprog one to run a model rail layout using JMRI software. So I’ll be looking for any help and suggestions. The first problem I have is in getting my Raspberry to cocnect over WIFI with my Ipad Pro.
Grant I don’t use ipad but are you wanting to connect using the Vnc viewer for remote access to your Pi4?
I’m doing model RR a little different perhaps. I’m using the DCC++ on an Arduino Maga . The play is to use a Raspberry pi to control the signals and a PC program to send commands to both. www.knob.com/train_thing/ is where the project is so far.
Hi, To be honest, I’m not sure of the best way to progress. But! I’ve bought the Raspberry and Pi Sprog as recommended. So I’ll persevere withj that system. Only need to work out how :-)
If you’re running the desktop on your Pi, scroll down the main menu to Preferences and Raspberry Pi Configuration. Enable VNC. Then download VNC Viewer from the Apple app store and connect via the IP address of the Pi.
I’m Kevin. Currently I am actively retired. Most of my career was spent in computing, from old IBM and ICL mainframes to pc’s on WAN’s and the Internet. Now I am learning as much as I can about IOT. My focus is on things environmental. Accordingly I have 4 active monitors setup here in Kildare, Ireland on the Luftdaten site using the Enviro+ board and the PMS5003 sensor. I have a variety of Raspberry Pi’s from the Zero’s through to my latest Pi 4. I also have an allotment and produce a lot of my own veg. The allotment is my escape from technology. I don’t have any sensors or actuators up there yet but maybe next year. I also have a few arduino’s and have done the usual blink type projects with them. I will probably use ESP32 LoRa arduino’s on my allotment when I get going on that.
Regards, Kevin.
Hi, I am Karl, a total Linux newbie (and dummie ;o) ).
However I like to use RasPi as little helpers for this and that.
So far, by using “G’s” search I was able to figure out how to get various projects going on RasPi.
My latest project is tracking and recording of air quality and noise levels.
Bougth the Zero WH and Enviro+ and… first things work after couple hours. Now I try to figure out how to write the values provided by python scripts into my MySQL database, hosted remotely.
I am convinced there is huge potential in sharing environmental data, @ almost no cost for hard- & software.
For the sake of guessing my age…I wrote my first “hello world” on digital equipment’s PDPs
Hey Kevin,
John here in California.
Please tell me which OS image you’re using on the RPi. I’m trying to get my Zero, running Buster, to run the enviroplus scripts on boot-up so I can run it headless, outdoors. Can’t get ‘cron’ scripts to do their thing. Any suggestions?
Thanks.
Hi John in California, I’ve never got the hang of Cron. First thing I do is install xterm because the ordinary terminal console lacks some functionality.
sudo apt-get install xterm -y
Then make an autostart directory:
mkdir home/pi/.config/autostart
Then create a file in the autostart directory using nano with the following lines:
[Desktop Entry]
Type = Application
Name = Luftapp
Exec = xterm -hold -e ‘home/pi/enviroplus-python/examples/luftdaten.py’
That should work, I don’t know if it matters what you name you give the file but I used ‘luftdaten.desktop’. If you changed the directory structure or the name of the program that communicates with Luftdaten then reflect those changes in the last line.
I have also changed luftdaten.py to reboot my pi zeros every 36 hours as there seems to be a memory leak in the code/functions provided which causes a hang.
Hi I am Salih, I have recently been introduced to the wonderful world of Pi’s and upon my first succesful project with a Picade I am now here to seek help on my second project which is the pirate radio. Great to be a part of this forum and hopefully I will one day also help others but for now I will be asking many questions :)
I’m Alain, and I love learning / playing with Linux, bash and related toys. My present projects include the installation of OVM5 onto my Pi4 4GB, and the creation of a “home cloud” hosting my various archives.
I’m also a new user of the Pimoroni Fan Shim – recently installed onto my Pi 4 4GB. Works quite well BTW, although I’m trying to find a way to stop it when the machine shuts down… :-)
I’m also facing some problems with OVM5 on my Pi, which displays fatal error messages related to a version of Python, so I will post a question in the Technical Support Forum as my problem may be linked to the Python script handling the fan.
My name is Alejandro. I like DIY stuff, and I am mainly focus on IoT stuff using node.js! Although sometimes I just like to play some music with the Itty Bitty Beat Box.
I am TCIII, a retired System Engineer, living in Central Florida USA and I am heavily into robotics with such projects as Donkey Car, Jetbot, Jetracer, Lino Robot, and real time object tracking!

Hi, My name is Toby, I work testing transceivers for the Oneweb LEO project. Interested more generally in electronics and wanting to use this forum to keep up with things.
