Ah, the head magnifier. Most geeky of headware short of LED-enhanced steampunk iris goggles. (Note to self: get/make LED-enhanced steampunk iris goggles!!!) This is not going to win you a fashion award. On the other hand, it's great at things like reducing eye-strain, and reducing errors from misreading incredibly tiny writing on silk-screened PCBs or chips.
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!
I decided to start with something easy instead of trying to shoot a project from beginning to end, especially with the limited space and time that I "enjoy" at the moment. So I'll be beginning with some reviews of the tools and products that I use when I'm working,
This is a smaller, indoor version of something that I've considered doing. I've been interested in hydroponics since reading older Heinlein, Asimov, and Norton sci-fi, and how it could combine air and water recycling, along with providing food.
So one of the more common chips that are used to control DC motors and Steppers is the L293D. It's a really simple chip, that's not too bad to hook up. Used with the Stepper.h library that ships with Arduino it's pretty darned easy to use.
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.
This is something that I've been asked several times, usually by people who aren't into electronics. The thing is, the people who have asked me are almost always really into making/crafts or DIY, or something similar...things that Arduino is just great for!
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.
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!
Feedspot has put out a "Top 20 Arduino Blogs on the Planet" post, and somehow they put me at #17.
