Transferring from Alaska to United
Quick coffee before I head to the airport

My bag check number for today at XOXO. I hope this isn't a sign.
This used to be my high school — with microformats
#xoxo beer meetup
Going home for the night. Gotta charge the kitten battery! Great to see everyone tonight at @xoxo!
#XOXO 2019 begins! — with Kevin, Tantek, Reid, microformats, anomalily
and now the light behind the litter box glows red when it's dirty and green when it's clean! No more needing to peer into the little door to look for stuff in the box!
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!
well that was one of the nicest sunsets I've seen from an airplane in a while!

Working on a little display that will sit in a picture frame and show my next upcoming flight! Powered by a raspberry pi which parses the flights from the microformats on my website, and shows either the next upcoming trip, or if I'm currently away, shows the details of the flight home. This e-paper display is really nice looking too!

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
Got here early to submit the first of many permit applications
📍 Olé Latte Coffee PSU
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.
Made some good progress on building my automatic cat feeder today! ⁣ ⁣Tore apart a kitchen scale to extract the load sensor and platform. Built a stand out of some MDF board. Attached the scale to the base, mounted the dispenser to the back. ⁣ ⁣Tomorrow I get the motor and can mount that to the back as well as wire up all the circuitry! ⁣ ⁣In the end, this will be able to drop food into the bowl only if the bowl isn't already full. It'll also track how much is left in the dispenser, as well as hopefully be able to tell when she actually eats by measuring the weight of the bowl! ⁣ ⁣#homeautomation #internetofthings #automaticcatfeeder #smartfeeder #diy #arduino
