I had the honor of speaking at the 2018 Hackaday Superconference over the weekend. It is one of my favorite conferences of the year. The engineers and makers I met there are focused on using their creative energy to make the world a more interesting and better place. I posted a preview of this talk in my “Humble Indicator LED” post earlier this year. This later morphed into the talk shown below. It’s about circuit designs that I have found or used in my life to save products. Watch the talk here:

Corrections (of course):

• 7:10: The LED schematic for the on/off indicator was copied without testing. A working version is here.
• 23:30: In the course of being cheeky I call it an instrumentation amp (wrong), but later correctly call it a differential amplifier.

Many people have been asking for the slides, I have them here:

I’ve turned off the comments for this post, as I’d love to discuss this over on the Contextual Electronics forum. Please stop by and let me know what you think!
