Python weather sensor upgrades

Well, the rain gauge has been working perfectly. Time to get some more data about the world around me.. I was reading about the BME280 sensor which provides accurate temperature, humidity and barometric pressure readings. I thought it might be a good choice for the next upgrade to my weather station. So, here we go.Continue reading “Python weather sensor upgrades”

LoRa Rain Gauge and Weather Server

So it rains here in Arkansas a bit and I have always wanted an automatic rain gauge and weather station but I am too cheap to buy a decent one.

Python Remote Gate Monitor

Here was the issue.. We have three sight hounds, a Whippet and two Silken Windhounds.

Working on seemingly microscopic electronic parts is a struggle and proper illumination is becoming a requirement. Don’t worry kids, you will get here someday and see what I mean. Recently, I bought these cheap LED T5 lights for myContinue reading “T5 light fixture mounts”

Raspberry Pi Pool Controller

It’s been a while since my last project. I have been working on something a bit more complicated this time. Here is the story… Once upon a time there were three nerdy friends. Two of these nerdy friends owned homes with pools and over the years accumulated a plethora of information about how they work,Continue reading “Raspberry Pi Pool Controller”

WiFi Line Level Volume Control

Update 10-2020 So, there was a bit too much current coming from the TV and it was causing the chip to be overdriven. I put a resister inline with the input and that solved the issue. I have updated the drawings and the images. I used a variable resistor as I had to try aContinue reading “WiFi Line Level Volume Control”
