Finished the picture frame that shows my upcoming travel! It shows my current location and local time, the dates of my next trip, and my departing or arriving flight information! Let's call this v1 tho, because I need to get a better matte for the frame, not just the cheap cardboard that came with it that i tore while cutting it. I might spring for a bigger display next time too! But overall I'm pretty happy with it!
I made more progress on the cat feeder tonight! I attached the motor to the back, and the shaft now goes thru and connects to the original (modified) plastic shaft from the dispenser. The lid has an ultrasonic distance sensor pointing down at the food to be able to tell how much is left in the chute. There's a button on top to be able to manually dispense a dose. Lastly, I added a terminal block to connect the wires from the scale for easier mounting to the processor later. Next up, I need to start connecting all the components to the circuitry! The load cell amplifier, stepper motor driver, and finally the esp32 controller. Then it'll be time to write some software! #homeautomation#esp32#arduino#catfeeder#hackyourcat#cathacks
Adding a couple new sensors tonight. Attempting a sound level sensor (should report roughly how noisy it is inside), and a color temperature sensor, which I'm hoping can tell me how cloudy it is outside and how much sun is coming in the window.
So far out of all the home automation devices I've connected to this Raspberry Pi, the most reliable ones have been 433mhz transmitters and ESP32s on wifi. I've been getting spotty performance of Bluetooth and Z-wave devices. Could be that the Pi isn't powerful enough, or could be because simpler is just better.
I just installed this neat motor which can drive the chain on my blinds! Now I'm brainstorming various rules to cause the blinds to open and close. So far:
• Close the blinds once the sun is high enough to start shining into the room • Open the blinds when the sun goes down in the evening • Close the blinds when the TV turns on • Close the blinds when I get in bed
