In this presentation, we’ll take a look at how the secure shell (SSH) protocol can be used to to tunnel many different types of network traffic. We’ll cover X Window forwarding, local port forwarding (think VNC), and how to use its support for the SOCKS protocol.
I decided to build my own Raspberry Pi music player using Python, as the available players didn’t really do what I wanted. This is Python at the beginner level, and the saga of making the player. Mostly it is about the little things in Python that caused me to stumble for a while. The music player is functional, the interface isn’t elegant, and I learned a few things about Python programming. – Don
KiCAD is free software suite for electronic design automation (EDA). It facilitates the design and simulation of electronic hardware. It features an integrated environment for schematic capture, PCB layout, manufacturing file viewing, SPICE simulation, and engineering calculation. Tools exist within the package to create bill of materials, artwork, Gerber files, and 3D models of the PCB and its components.
Jim will cover the details of Infra-Red Communications, including basic components (emitter & receiver), data encoding methods, external components & software, how to generate pulses, and how to receive pulses on the Pi Pico.
