Arduino install:
Start IDE
Install TJpg_Decoder library
Open examples>Tjpeg_decoder>SPIFFS>SPIFFS_web_spiffs
change wifi credentials
and the url to your php script.
bool loaded_ok = getFile("https://myserver/onkyo.php", "/M81.jpg"); // Note name preceded with "/"
replace bottom part with
// while(1) yield();
delay(5000);
SPIFFS.remove("/M81.jpg");
Or I could make a cool audio visualiser, like the posted WLED version
Ehh .. not posted (well I can’t post everything)
What about a game of life display? Using a web interface for inputting the start situation of the cells
Conway’s Game of Life is a cellular automaton. It consists of a grid of cells, each of which can be alive or dead. The state of each cell evolves based on simple rules: any live cell with fewer than two live neighbours dies (underpopulation), any live cell with two or three live neighbours survives, and any live cell with more than three live neighbours dies (overpopulation). Additionally, any dead cell with exactly three live neighbours becomes alive (reproduction). This simple set of rules can lead to complex patterns and behaviours.
But back to the demo …
What about a 6502 with 64×64 pixel display!
What would be needed?
6502, with rom and ram
Some IO chip, don’t know which one yet
The 64×64 pixel matrix
A sound solution (simple chip tune player)
3D printed enclosure
Using some libraries and a framework setup, maybe there is a way to make a cool and cheap demo machine
Do you have any suggestions ideas? Comment or email me!
Besides sending notifications and controlling my tv using bash, Nodered and HomeAssistant, i wanted to look at developing and homebrew for WebOS.
Goto the WebOS Dev website and register.
Install Developer App on your TV.
Login and write down your access information.
Remain session can be extended using the button, or using a script.
Below how to access you tv using ssh
wget http://IP_FROM_YOUR_TV:9991/webos_rsa
mv webos_rsa .ssh/
chmod 600 .ssh/webos_rsa
ssh -i .ssh/webos_rsa prisoner@10.1.0.14 -p9922 -T
Enter passphrase for key '.ssh/webos_rsa':
Enter the key mentioned on the Developer App Screen on your TV
Note the -T .. this disables pseudo terminals,
You won't see a prompt, but commands work
You can remove passphrases on ssh keys using below
ssh-keygen -p -f .ssh/webos_rsa
Enter old passphrase:
Enter new passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved with the new passphrase.
Some AI generated art I made – electronic components being sucked into a black hole.
This is NOT a post about the pi-hole project. Of which I apparantly never posted my setup.
I needed an extra PI for a project, and I always try to keep one spare. But they are always gone, in use, missing .. whatever.
So I can´t work on this project right now, so lets rant about disappearing stuff
Like they are being sucked up in another dimension .. gone. WHERE ARE THEY?!?
How to keep track of them?
Any suggestions?
I used to have a sheet, but I often forget to keep track. Do I use a MAC address scan on my switches? First 3 parts of the Mac address are vendor specific.
So far i’ve found : Octopi, Beerbrew computer, Retro Arcade, Picore, Nodered, Domoticz 433toMqtt, Ledserver, Lasercutter-etch-a-sketch, mobile LMS music server, Pressure Lab AP, Escape Game AP (3 of them), one unused Raspberry zero (without Wifi), One at my old work, one broke, Kodi+Netflix,Ansible project, found another one .. Jumanji/Dashticz/NoderedDashboard demo (with screen) WHERE THE F are the rest of them? (Sdcards with temporary projects on them 29, I need to combine project on those cards. I’ve got a 64Gb card holding a Rpi OS and only a 1K python script!)
And Arduino’s are even worse … they are all over the place. Those are probably 100+ (ESP32, 8266, Nano’s, Mega, M5Stack and alikes)
I know i have many temporary projects, but I keep most things organized in my projects containers.
One of the rows with Ikea containers, a few for bigger projects and now i’m using the plastic boxes you get when you order chinese or thai.
