On the Internet: W2AEW videos, Raspberry Pi programming, classic radio

Here are a couple of Internet resources to start off the week:

W2AEW on YouTube. Alan, W2AEW, has a great selection of cool videos on YouTube. Some of the latest cover the basics of phase-locked loops, how to zero-beat WWV to check out a frequency counter’s accuracy, and a tutorial on resonant circuits. Good stuff!

Baking Pi – Operating Systems Development. This course, published by the University of Cambridge Computer laboratory, is a free online course that takes you through the basics of operating system development. The Web page notes, “[This course] ┬áis aimed at people aged 16 and upwards, although younger readers may still find some of it accessible, particularly with assistance….I have tried not to assume any prior knowledge of operating systems development or assembly code. It may be helpful to have some programming experience, but the course should be accessible without.”

Classic Exchange. Mac, WQ8U, wrote to the Glowbugs mailing list, “The Classic Exchange (CX) is a low-key, on-air celebration of rigs of days gone by – particularly boat anchors. The latest CX Newsletter is available on the CX web site, as well as details for the next CX on September 16th (for AM and SSB) and September 23nd (for CW). Please enjoy the newsletter, spread the word and join in the fun during the next CX.”
