Very good video about the chip shortage. There were fires in several plants, natural disasters like the earthquake in Fukushima, and too much dependence on only a few factories. We need to prevent this from happening again.

2021-02-08 IEEE.ORG Website Is Not Private. Intersil ICL 8038 Function Generator
Chrome won’t allow me to connect to the spectrum.ieee.org website because it’s saying it’s not private. I go to learn more and they don’t have any way to override the error message. I went here first to read the story and tried the link at the end to comment. https://spectrum.ieee.org/tech-talk/tech-history/silicon-revolution/decoding-the-innovation-delusion-nurturing-the-maintenance-mindset They asked in an article

I found that 100 uH was a good all around value for these solar garden light circuits. But at the time I made these around 2009 the 5252 4 legged chip was uncommon and almost all the garden lights used 2 discrete transistors. I don’t know why they started using the 4 legged 5252 –

LED Indoor Motion Sensing Lights – Decrease On Time
I bought two of these motion sensing LED lights for my hallway. They have a rechargeable cell that is charged through a micro USB port. To see one inside watch big Clive’s YouTube video – the ebay link to buy them is in his description. The charge lasts for more than a week with frequent

2017-08-27 A 555 Is Easier And Cheaper Than a PIC
From a FB group post. “primitive transistors” I think that’s ironic. The 555 makes the design easier for the builder. It has all the parts so the builder doesn’t have to build from scratch. Like making a cake using Betty Crocker’s cake mix instead of flour, eggs, etc, and no need for a recipe. It’s
