Silly Job Title: Capacitor Captain.

In this video I make excuses for why you haven’t had a video from me for two weeks. Excuses, excuses.

It is still my ambition to release three videos per week, on Tuesday, Thursday, and Saturday.

As I mention in the video I have been working away on the Learning the Art of Electronics project and making notes for all five of the referenced books but I still have a heap more work to do. Further, I’ve been working through the first edition of Learning the Art of Electronics because my second edition hasn’t arrived yet. So today I bit the bullet and canceled my order of the second edition from Amazon AU (I’ve been waiting since January) and placed a new order with Amazon US so my second edition should now be arriving by May 24, later this week.

I have ordered some bits and pieces for my Logitech BRIO web cam including this stand, so I should be able to start making maths videos on my channel soon. But it will be very basic high school maths. If you want more serious maths I would be happy to recommend my friend who makes advanced maths videos on his channel Learning as a hobby.

Speaking of my mate on the Learning as a hobby channel he recently scored a copy of the CDROM that comes with Principles of Electronic Circuits 2ed and is making preparations to send me a copy (either as an ISO or in the snail mail), so standby for more on that. This is a super exciting development because I had concluded that finding a copy of this CDROM was going to be impossible, but here it is!

The long projects that I’m working on which are presently brewing include:

  • Silicon Chip and Jaycar Mini Project JMP003
  • Demo of EEVblog BM2257 multimeter
  • Old book teardown of Electric Circuits
  • Project #1 from Maxitronix 30in1
  • Lab #1 from Learning the Art of Electronics

I have made a start on all of the above but it’s going to take me some time to finish them all. In the mean time I am going to try to get some smaller projects done so that I can hit my target of three videos per week.

And that brings you up to date with news from the channel.

Statistician Answers Stats Questions From Twitter | Tech Support | WIRED

This was a good overview of what’s possible with statistics: Statistician Answers Stats Questions From Twitter | Tech Support | WIRED.

But I’m pretty sure that at t=11:23 he gets it wrong. The probability that three people in a family have the same birthday isn’t 1 * 1/365 * 1/365. but rather it depends on the number of people in the family (starting, I guess, at some epoch). This is known as the Birthday paradox.

To be clear: they’re not asking what is the probability of three people being born on January 10. They asked what are the odds of three people from an unspecified family size being born on the same day (could be any day of the year).

Chess strategy

I enjoyed this one: I wasted years losing at chess, until I learned this.

Focus on solid moves. Don’t attack, wait for opponent to blunder. Try to avoid pushing pawns unless you have to. You can develop C, D, E pawns. Open by putting a pawn in the center. Castle early.

After the castle we’re into the mid-game. Then every move we have to look for:

  • Checks
  • Captures
  • Threats

If there are no checks/captures/threats we go for Optimization. So develop any pieces still on the back rank or the C, D, E pawns.

So it’s Checks, Captures, Threats, Optimizations.

Note: just because you have a check or capture doesn’t necessarily mean you have to play it.

Bottom line: avoid blundering and wait for your opponent to blunder.

Silly Job Title: Connector Kingpin.

In this video I tell you about the new ITL Wiki.

The notes for Learning the Art of Electronics are there: ITL Wiki § Learning the Art of Electronics.

I am running late with Lab #1 from Learning the Art of Electronics. That video was meant to come out today, but I’ve pushed it back to next Tuesday so I have time to prepare the notes and record the lab.

See you next Tuesday? :)
