I was playing wih one optocouer recently. I created simple breadboardable board for playing with optocoupler on breadboard at development time.

I am sharing Kicad project and gerbers for case when someone is interested. They are also avaible at OSHPark as a shared project (https://oshpark.com/shared_projects/BltK0mIb). You can order 3pcs for 1.05 USD and free international shipping. When ordering I reccomend oredering more (even different) PCBs for making this business model ballanced and profitable.

All the documentation on Toshiba's site about semiconductors is very interesting. The e-Learning section has a lot of content about semiconductors explained in a simple way.

This one wasn't too hard - I managed to get all but two on the first go. Definitely important for safety - you'll find one in virtually every switch-mode power supply!

Something changed because the option to post comments has been restored. Opened a support ticket but it appears to have healed itself.

I enjoyed taking the quiz, especially reading material that shores up some knowledge. Great resource material.

I thought (16) was not worded properly since the LED is not what has a trigger threshold, but reading the way they define it in their documentation it makes a bit more sense.
