NodeMCU ESP8266 Wi-Fi SoC
NodeMCU Status: Our air conditioner is limping with a oil logged evaporator until we replace the unit in October. The thermostat is also limping along because of leaking batteries. I’m using these NodeMCU’s to measure the temperature and humidity throughout the house and turn on / off the power to the thermostat.
I am still having issues with the evaporator freezing today. Even after running the heat pump without the fan didn’t clean out the oil in the evaporator. (Boo!)
I found an error in the programming that turned on the compressor without the blower running. Luckily the temperature sensor at the air return manifold was satisfied and cut off the compressor before it was damaged. I added a separate check to make sure the fan was running when the compressor is on. The programming failed to catch another process turning off the air handler at the same time.
I also added a temperature check after the temp is satisfied. I run the fan while measuring the temperature at the evaporator coils, when that temp gets over 70 degrees it is safe to restart the compressor. Since I have temperature sensors in the bedroom I can accurately set the bedroom temp regardless of the house temp. (Within one tenth of a degree)
I took an old fan from the garage and put it in the duct to my “Man Cave”. The O Scope measured slightly higher than 80Hz pulses from the fan. That will give me a relative speed to check for ice in the evaporator slowing down the air flow.
DC Power generating and Inverter
Homestead DC Power: The bottom section of the above picture is two 15A 24V power supplies that work alongside the solar panels and provide power for the 300W inverters on the right side. The idea is that during the day a relay connects my computers to the 300W inverter and run them on the solar power. The system doesn’t make as much power on a partly cloudy day, much less in fact. Most days I make about 13 cents worth of electricity.
Articles about our current racial climate
A medic, who gave the name Phoenix, confronted an officer she said had maced her and beaten her. She and a friend criticized the police for dispersing the entire crowd when only a few people had broken into PPA. “You are taking the actions of one person and you are punishing a movement,” Phoenix said. “One person did a fire and you think it’s OK to attack everybody here?”
“You’re all practicing group punishment,” the officer replied. “Because a few cops have done wrong things and you think we all need to suffer and be out here 69 days straight.” https://www.opb.org/article/2020/08/05/portland-oregon-protests-police/
Finally, let’s note that protests at private homes are strategically misguided. Such protests tend to turn off potential sympathizers. The goal of political protest should be to generate outrage and empathy among possible supporters. But a protest at a home or at a restaurant defeats that purpose by making the protestors appear to be vindictive bullies. Public protests and civil disobedience are more effective at persuading others to see the justice of one’s cause.
Peeved protesters may get a thrill from demonstrating at a politician’ domicile. But their anger is misdirected. The official at home is not the problem. Rather the problem is what happens when the official is at work. These protesters would be more effective if they were informed by the history civil disobedience and by a more systematic conception of political power. The Problem of Protesting at People’s Homes
