Some different perspectives on what the tech job scene is like these days, and then some other random things. Honestly I am not sure what has happened in my feed today.

Propagation of electricity

Thanks to Craig for referring me to Brian Haidet’s AlphaPhoenix channel.

I found the following four videos on the AlphaPhoenix channel explaining various aspects of the propagation of electricity, which goes some way to explaining how the high impedance headphone might work in my 10in1 2/10 project.

While watching the videos I discovered that Brian’s oscilloscope is a Siglent SDS1104X-E (100 MHz) Oscilloscope, a pretty nice looking bit of kit!

This post is part of my video blog: In The Lab With Jay Jay.

In this video I do the second Maxitronix 10in1 Electronic Project Lab project: Morse Code Oscillator.

In this video when I’m talking about the tuning capacitor I say that 0.001uF is 1,000 picofarads, but of course it is 1,000 nanofarads; I would have put a correction into the video but I didn’t notice the error until I had already published it.

There was some follow up discussion about topics raised in this video over here: propagation of electricity.

Stay tuned for the upcoming projects. If you’re interested in seeing them don’t forget to subscribe!

Also, if you’re interested in getting any of these Maxitronix kits yourself the best place I know to look is on eBay. Let me know if you find them somewhere else!
