2020-03-13 Switch To Hydrogen

Also posted to CleanTechnica comment to article with “amirite” in title on Mar 14 The world needs to ‘catch up’ by ending use of fossil fuels ASAP, and substituting hydrogen in their place. If we don’t, that 1.5 degree warming goal will be overshot, and things will be exceedingly difficult. The renewables generated hydrogen can

2020-03-09 Chernobyl & Fukushima Cancer Deaths Estimates

This coming week marks the 9th year since the Fukushima Dai Ichi nuclear disasters. I keep hearing that all the deaths due to nuclear power plants add up to just a 2 digit number. But it’s not that simple – the nuclear apologists try to understate the deaths and damage done. I don’t think that

2020-03-07 Coal And Its Evil Results

In China, industries burned coal and people burned coal for cooking and heating. In cities like Beijing the air pollution was so bad that it was hard to see the stop lights and pedestrians had to wear facemasks. The pollution killed estimated millions of people with lung problems. China realized this and has done a

2020-03-03 The 5G Technology is NOT Linked to The Corona Virus

This false claim is being spread around the Web by conspiracy theorists, one being David Icke. There has never been any evidence linking the two. Be aware that these articles use pseudoscientific terms that attempt to make the reader believe the claims are based in fact, but they’re not. Don’t be tempted to go over

The beginning isn’t clear about how it looks. First, scroll to end and look at the photo. https://www.randombio.com/capacitor.html

2020-01-22 I was Zucked by a Facebook Group Administrator

Jeff Collins There are too many admins who have no consideration for members and give no warning to members that they violated some capricious rule that the admin arbitrarily made up. I was banned without warning from an Arduino group for something that wasn’t my fault. The admin decided I had to apologize for blocking

2020-01-01 VA3IUL Website RF Projects

I spent too much time looking at the schematics and projects at this website.  Lots of interesting things to download.https://www.qsl.net/va3iul/Homebrew_RF_Circuit_Design_Ideas/Homebrew_RF_Circuit_Design_Ideas.htm

2018-09-02 Mims Mistakes In Audio Amplifier

From FB group Building Transistor Radios, 2018-09-02 I already see one mistake. On p.27, Audio Mixer. The R6 is only 1k. The voltage divider R5 and R6 will give a voltage less than 0.6 at Q1’s base, which means Q1 will not be forward biased enough and the circuit won’t work or else sound distorted.

2017-06-08 AD Has ADP5090

Ever since I’ve been experimenting with Joule Thiefs I’ve done so with the intention of using the circuit for boosting a low voltage source to power a higher voltage circuit.  So I think this Analog Devices ADP5090 is very useful for doing just that: powering circuits up to 200 mW from very low voltage power
