Raspberry Pi has a limited amount of RAM and more cannot be added since it is a single-board computer. The Pi 3 has a mere 1GB of RAM. The Pi 4, depending upon the model has up to 8GB RAM. Software applications at times demand more memory. Most of the time this memory requirement...

I have designed PCBs for making the Pi Pico-EEPROM connection easier. There are variants to the PCB designed. In the sample PCB image, you can see that one has a jumper for write protection and in the other, the write protection pin has been exposed. The advantage of using the board wi...
The Raspberry Pi 5 has a new chip to interact with the GPIOs: RPI1. All info on https://www.raspberrypi.com/documentation/microcontrollers/rp1.html Pi4J V2 uses LinuxFS and PiGpio to interact with the GPIOs, but these are not (fully) compatible with that RP1. @alex9849 proposed via...

When the Raspberry Pi came out, I decided to add a FPGA to it to enhance its functionality and provide non-software ( hence no virus nor easily hack-able ) functions for development. ( Like cryptocurrencies algorithm or key generation and keeping ).In this arrangement the FPGA provides...
Open the CUPS web interface:https://<IP>:631 In the top bar menu, click on the “Administration” menu. Then click on Add printer: CUPS will ask you for a login and password. Use the credentials for your system, the same as on Raspberry Pi OS (“pat” in my case). ...
The text after GPIO.IN refers to theinternal pull-up resistorof the Raspberry Pi. You need to enable this to get a clean reading from the button. Since the button is going to the ground pin, we need a pull-up resistor to hold the input pin HIGH until you press it. ...
Before we go any further we need to assign a static IP address. If your Pi's IP address is randomly assigned by your router's DHCP server, then the IP address could change later and you wouldn't be able to connect via VNC (or Sonos for that matter). RIGHT-click the network connecti...
To help users build their new hybrid creations, Lego has even released its first-ever component designed to connect to something that is not another piece of Lego. Called the Maker Plate, the piece lets makers stick their Raspberry Pi directly into their Lego construction. The ...
