This is a YouTube video. This guy did a very good job of building an off-grid solar system. It’s transportable, uses four 100 watt panels, two 12V AGM batteries in parallel, can supply 120VAC pure sine wave at 2000 watts and costs under $1,900. This is an excellent video with plenty of details. He calls

I’ve been seeing the sprinklers reaching a smaller radius after several years, and brown spots between. I was thinking that it was caused by a clogged pipe. I also had some constantly leaky sprinklers that were causing the grass to become soggy and mushrooms were growing. Then I noticed my water bill was several tens

See my previous blog. The circuit runs off a photovoltaic cell that puts out approximately 3.85 volts during a sunny day. The chirps put a small load during the noises and the voltage changes very little, maybe .03 volt. I think the photovoltaic cell could drive a few LEDs without any problem. I thought it

I found this circuit at 5 or 6 different websites, all identical except some were in color, others not. The schematic and part values were all the same. I didn’t have a 1k CT to 8 ohm transformer (Radio Shack 273-1380) so instead I used a transformer with four 600 ohm windings and I tied

The Supreme Court decided against the Obamacare law requiring employers’ health plans to pay for birth control. The employer must have religious or moral objections to birth control. This is not a major victory for Trumpism because the employee can find a job somewhere that doesn’t have an objection. There is the “externalities” or unintended

Kucharsky is an epidemiologist. This is a great 13.7 minute talk similar to Ted where he explains the four “D. O. T. S.” determine the R (reproduction) value. Start at the 4:10 point. https://youtu.be/G-GlD3oVxE8 An article on antivaxxers and CoVID19 They’re already starting to cause people to not want to vaccinate https://www.sciencemag.org/news/2020/06/just-50-americans-plan-get-covid-19-vaccine-here-s-how-win-over-rest
2020-07-08 This article tells how growing feed crops for livestock is using up 23% of the water. The large part of this water is used to grow the feed for the cattle. The northern part of Texas and Oklahoma are running dry because the underground aquifer is being depleted. https://www.theguardian.com/environment/2020/jul/02/agriculture-cattle-us-water-shortages-colorado-river?utm_term=RWRpdG9yaWFsX0dyZWVuTGlnaHQtMjAwNzA4&utm_source=esp&utm_medium=Email&CMP=greenlight_email&utm_campaign=GreenLight
