Well, I finally retired which means I need to fill my spare time with something. I came back to the Arduino as something to keep my brain active. Surely a lot has changed in 9 years.
I plan to make a simple web server with an Uno and ethernet shield to remotely trip relays from my smartphone. I dug out my code and boards from 9 years ago (!) - I never throw anything away.
I also have a couple PCduinoV2 boards, one of which had LAMP running on it on SuSE, the other never used has Ubuntu. Now the SuSE board gives 'too many ECC' errors when it tries to boot and seems to hang. I can't get anywhere trying to make it run.
What happened to PCduino? Searching the web, there's very little activity. I thought maybe I'd buy a newer and up to date board but sheesh, they are being offered for sale at $75 - $250. I paid $30 or so for mine in 2013. Inflation that bad?
Any tips on where to find good info for trying to resurrect my boards? The main site seems to have been linksprite.com - as that's where many links took me. But it's dead and gone.
Resurrect your pcDuino? Put them on amazon for $150 each and make some profit. I guarantee right now there's some small company that has a product based on them that is desperate to buy any they can find.
Then use your profit to buy an ESP32 that will do all that you want on one little board that costs $10 and will fit on your finger. A lot has changed in 9 years, indeed.
Ha, ha. That is how I got started with Arduino, the PCduino. Fond memories. If you want to continue using Linux, get a Raspberry Pi. The Mega is a better choice to use with Ethernet than the Uno. Or use ESP if you have wifi.
LOL, why didn't I think of that? Yeah I should just sell and take my profit!
ESP32 - woah, wasn't aware of those. I was once upon a time playing with nrf24's but never really got a good result. Back before WiFi took hold. I was going to build a bunch of nodes with bare ATMega chips on the cheap.
Yea, RPi's. I got one running as a MQTT Broker, doing TensorFlow image processing, FTP server, and a few other chores sending and retrieving data to my 13 ESP32's.
I love pi's. They make networking and UI work absolutely trivial. One problem though: chip supply issues make finding them a matter of pure dumb luck these days.
For the simple web server for relay operation, you don't need Linux. No reply from the OP yet about wifi availability, but I gave up on Ethernet because it's increasingly harder to find an Ethernet port anywhere.
