More than that, too. I bet you could guess my age within 2 years with solely a list of technology I've used. I don't think it would even have to be sorted by date.
Could I use a $0.02 microcontroller unit that has 48 bytes of RAM to function as the computer for a homemade networked camera package? Like, attaching the MCU to a one dollar WiFi module to begin building an amateur information technology system with a Raspberry Pi single board computer performing as the mainframe server?
So, there's already entire systems on chips? Like the Raspberry Pis and ESP32s?
Are they robust and general purpose though? Can they be integrated into any little home project? Or would you have to design and make your own microchips for your own cases?
If you're familiar with the ESP32, the ESP8266 is similar, but less capable and less expensive. As far as I know, the ESP8266 was designed and sold as a wifi add-on chip for a separate microcontroller, but then an SDK came out and some applications don't actually need a separate microcontroller.
Depends on your project if it will work, but I use them around the house to report on temperature and humidity, and I've got one setup on an arcade video converter that I was hoping I could get better output from (but it didn't really work).
