I have this little SLA battery that enables my emergency generator to start without using the pull cord. I don’t have a maintainer on this batter (and maybe I should), so every once in a while I like to charge…
About a year ago I make a bunch of loaves and fishes for a Godly Play story at the church. I made them out of 3mm door hanger plywood that I picked up at the local craft store using a…
Backstory: We took down a red oak a couple years ago (Part 1 and Part 2) and I got it milled up for projects. Wifey wants a desk but the grain is a little tricky and my thickness planer just…
I use ESPHome for a number of projects including LED task lighting, and my devices often use an inexpensive TTP223 capacitive touch sensor as a button. I like to be able to tap the sensor multiple times to cycle through…
I use inexpensive TEMT6000 sensors in various projects to detect the level of ambient light. I originally hand-coded the firmware, but now I use ESPHome. My projects are usually 3.3V because I use pretty bare boards like ESP-12F instead of…
I’m using ESPHome with Home Assistant for a bunch of home automation projects. I want to be able to flash some of the lights in a Morse code “SOS” pattern as an annoying alert that something has gone terribly wrong.…
I have a bunch of ESPHome/ESP8266 projects, several of which are have been plagued by repeated disconnection during seemingly random times of instability. Sometimes they’ll be fine for days, and then suddenly they start acting up again, and it can…
I’m using connections to my home network to indicate presence of family members primarily using the Ping (ICMP) integration, but with this method, iPhones frequently “go offline” because they don’t respond to these pings when trying to safe power. The…
tl;dr The ESP-12F ADC pin appears to consistently read higher values at times when the processor is not as busy. I worked around this by taking the average of multiple reads, and discarding any averages where the number of samples…
I picked up a $9 Comidox logic analyzer for some ESP8266 work I’m doing, and so far it works great. You really can’t beat the price. Plus, it’s not just for Linux. Here’s how I got it up and running…
