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

2020-05-14 Low Quality LEDs From Small Vendors

from FB comment in Vintage Transistor Radios Pablo E. Laredo I used to buy LEDs from small vendors on eBay. I found that most of the 5mm LEDs that I got from the small vendors were seconds, the chip wasn’t centered so the beam was off center, or there were bubbles in the clear epoxy

2020-05-16 Renewables Vs. Nuclear Power Plants

The actual costs of the new NPPs (Vogtle in the US and Okiluoto in Finland) have gone far overbudget – tens of Billions of dollars, plus years of delays. It’s not antinukers, it’s huge cost overruns and delays that are preventing investors from building new NPPs. NPPs are not capable of competing against renewables. The
