ESPHome Temperature and Humidity Sensor with Home Assistant

I needed to add a simple temperature and humidify sensor to add to Home Assistant, both for my information and for various automations. At first, I went with the Aqara temperature and humidity sensor, but they were too unreliable with my setup. Even if I can get them to pair, they often will drop after…

Custom Arduino Uno shield for growing oyster mushrooms

I’m building an Arduino project to automate growing oyster mushroom in a box. I can’t vouch for the results of growing the mushrooms yet, but the electronics are now complete, so I wanted to do a little writeup on it while it was fresh into my mind. For this project I was aiming to use…

“Creating Your Own Printed Circuit Board At Home” at WTM 2020

It’s been up for a while, but I gave a (virtual) talk at Woman Techmakers Montreal in April 2020 about creating your own circuit board. I wanted to show that creating your own circuit board is not that hard and expensive with KiCad and a good PCB fabrication house. It was not supposed to be…

Creating and Ordering a Circuit Board

I have plans for a small weather station that’s been lying on my hard drive for a while. The basic design includes ESP8266 modules that send data over to a Raspberry Pi base station that logs all that data and can create graphs. I’ve done a good deal of prototyping and breadboarding for the electronics,…
