Video: Storage

Well, I really can't say enough about storage. It's pretty much essential to anybody, anytime. But for DIYers and Makers, it becomes even more important. And the more restricted your space is, the more important it gets!


Python: Publishing messages to MQTT topic

MQTT is almost a must for everyone who’s interested in home automation. I must admit, I’m reblogging this as much to share with everyone, as to be able to find it easily myself later! I’ve connected using a library on an ESP8266, but not from Python. That’s something that I was planning to figure out anyways…it will make propagating a unified date/time to all of the devices on the network that don’t have access to NTP in an easy way…like ESP8266, arduino, etc, for one thing. And that’s just off the top of my head! If it works for MicroPython as well, then it’s even more useful.


The objective of this post is to explain how to connect to a MQTT broker and post some messages to a topic, using Python.

Prototype Build: Camera Light

This may look like a duplicate post, but it's actually something different. This is a step that I sometimes skip, but usually like to do if I have the parts. It's basically a rough build where I can see what mistakes I'm making before I do the "final" build. I look at it as the breadboard prototype is sort of like an outline for a paper that you write. It gives you the basics. The prototype build is sort of a first draft. It is your paper, but it's nowhere near ready to turn in. And then the final build is the finished product...not to say that it still wouldn't be further improved and iterated on, but that's just where the analogy breaks down.

ESP8266: NodeMCU Pin mappings

I had some problems with this when I first used a NodeMCU board. It’s simple enough to figure out, but it still can give you a momentary urge to yank out hair!

Thanks for making this easy to see and understand!


The objective of this post is to explain how to use the ESP8266 library defined constants that have the correct mapping between NodeMCU and ESP8266 pins.

Project: Camera Lighting – Prototyping

Here, I'm going to step through the prototyping process of getting this to work. Step 1:  The Power I like to set up the power component of my projects first, since if that doesn't work, I'm not going anywhere. Using PCBs with breadboards without soldering isn't all that friendly, but you can make it work… Continue reading Project: Camera Lighting – Prototyping
