More chromium woes

So it seems that my trouble with chromium is not over. Today a new twist. Thank God I still have Firefox! I will try updating and rebooting again, but can’t do that at the moment.

Math homework

Posted on by

I will let you in on a little secret: I love doing math homework. Always have, always will. I love the process. I love reading the problems, thinking of solutions, and checking the questions off one by one. Even when it’s easy, it’s still fun.

Just for fun I’ve gone back to my old high school math textbooks. I’m skipping years 7 and 8 and starting with year 9. Then I will do 10, 11, and 12, at the highest level.

At the moment I’m working through Australian Signpost Mathematics New South Wales 9 (5.1-5.3) Student Book, which is the year 9 textbook. I’m only up to page 10, fractions and ratios. I should work on it more than I do. Let’s see what I can do about that. :)

Silly Job Title: Craig Entertainer

Here it is! As planned, my new costume! Just for fun when I record electronics videos in my lab I’m gonna dress myself up like Egon Stetmann the scientist from StarCraft II:

The cosplay costume reveal is in this video. Also some news and discussion about the goals for the channel over the longer term.

As mentioned in this video I will have a new job title for my ID card for each video. The inaugural job title is Craig Entertainer, for my only regular reader, Craig. :)

Here are some affiliate links to the bits and pieces I got for the costume:

FILCO Majestouch 2SS Edition Keyboards

I ordered two new keyboards this morning. I got a 104-key one and an 87-key one. The gory details are documented on the keyboard page on my wiki.

Usually I like to buy V3 keyboards from WASD Keyboards in America. But the price for the two keyboards delivered would have been AU$841, which was just a bit too expensive for me.

So I had a bit of a hunt around and I found these Japanese FILCO Majestouch 2SS Edition keyboards on Amazon:

They both come with MX Speed Silver switches which are the ones I like.

While I was researching I found the following content mill articles which I enjoyed reading to learn more about mechanical keyboards:

AliExpress diodes

I ordered a bunch of SMD diodes from AliExpress (nine different types), and nine packages arrived, but they weren’t labeled. I tested everything to infer what I got, and they didn’t ship me what I ordered. My notes are here and the video of me doing all this is here.

I kept a note of the seller and will try to not order from them again. In the mean time I think I have filed the components that did arrive in the correct drawer.

Below are two happy snaps from this project. I guess on the bright side I got some practice doing SMD soldering and using my signal generator and my scope.

Oh, and I added a new item to my debugging notes, viz “is it plugged into the right socket?” (I had my output cable on the signal generator plugged into the wrong BNC connector on the device, that took some figuring out…)
