Stranger Things Message Lights

Stranger Things Lights This post will review how I created a web-controlled addressable Christmas lights to spell out messages like seen in "Stranger Things". This project controls a string of addressable LEDs in a Christmas-light design with a NodeMCU over wifi, using MQTT controls from Home Assistant. End Result: How it looks in a home assistant card: What you need: 1x NodeMCU 1x 5V Power Supply (8A) 1x Vinyl Stick-Up Letters (full alphabet) 1x String of 50 addressable Christmas Lights If you want to control it via the web, will need home assistant, MQTT server. Otherwise, it will just play the one message programmed into it. NodeMCU: Just hook up the signal line on the lights to D5. Otherwise, the lights and NodeMCU are on the 5V and GND lines of the power supply. ***Don't have the power supply on at the same time the NodeMCU is hooked up to USB, this can overheat the power supply*** Here is the arduin

Cardiology Blog

Dr. Wes's Blog One of the cardiologist I work with has created a great set of websites. His main blog has general comments on the medical profession in general and electrophysiology/cardiology specifically. He also takes questions on cardiology issues like sudden death and implantable defibrillators (ICDs), as well as has a general forum for Q&A. He also has a hilarious site with Joke T-Shirts that put a lighthearted spin on various diseases (with proceeds going to various charities). I like the "Death, been there done that" shirt.

Mobile Blogging

I figured out a pretty rapid way to post pics from my phone to the blog directly today, using the go@mobile.blogger.com email method. Pretty nice. Stay tuned here to see some major I-journalism, like police brutality or bigfoot or something. Or boring stuff like this picture of us driving out to the countryside.
