2020-10-30 Biden MUST Win — Trump MUST Lose.

With just a few days from the day of the election, there is a lot of speculation in the news about who will win. My educated guesstimate is that Biden will take the electoral votes by a large margin. Trump was a ‘useful idiot’ for the Russians in 2016. Trump was useful to the Russians

2020-10-30 Voter Dilution By Gerrymandering

My comment from FB about this politifact Rich Doyon And I suppose you think it’s fair to put all the best players on one team so that that team always wins. The gerrymandering, no matter which side is doing it, is unfair. It’s putting all the team members who are on one side (which,

2020-10-29 Freq Counter – Crystal Tester Mod For Low Frequencies

I got this frequency counter and crystal tester mainly for the frequency counter. Today I decided to test a few crystals, and was successful with ones above 10 MHz but not at 4 MHz. The two capacitors labeled C2 and C3 are the feedback to the crystal, and they were originally 22 pF. So I

2020-10-28 Cities And Climate

I looked at a photo of the downtown of a city with all its many skyscrapers, and the thought occurred to me that this collection of tall buildings has a very high surface area to volume ratio(see note) and that this is the least effective at keeping the hot or cold climate out. Just to

We need green hydrogen to power the whole world and leave the fossil fuels in the ground. Now! ************************** The European Commission plans on having

2020-10-28 Russian Vs. Silicon PNP For Output Transistors

Christopher The Russian transistors that I got on eBay were rated for much less than 150 milliwatts, which is very low and prone to thermal runaway (which is what causes the originals to go bad). Plus you are supposed to match the pair for equal base to emitter Vbe voltages. It’s so much better and

2020-10-27 Replace Electrolytics With MLCCs

Joe If the capacitor is in parallel with a low value resistor it may be a bypass capacitor for the emitter resistor of the audio driver stage. If it’s dried out, the audio will lose volume but still be weak. If it’s in parallel with the plus and minus power, if it dries out it

2020-10-26 Wind Turbine Radical Designs

I was watching a wind turbine video on YouTube and I was thinking about why they needed to have this big cylindrical tower that’s solid and has a lot of resistance to the flow of air. The one obvious reason is so that the maintenance people can go up the stairs or lift without getting
