Moving on

It’s kind of depressing when you think about it, but my ESP8266 project is held up by two little switches I need that are somewhere in the mail. It’s going to sit off to the side until those switches come, so I thought I’d shift gears and give you a quick preview of what’s coming up.

RF Transmitter and Receiver

IMG_0001I’ve never been much of a communications guy. Protocols and accommodating for noise and interference and all that has always been confusing/boring to me, but I seem to be tip-toeing toward it these days. I received two RF transmitter and receiver pairs in the mail today. I didn’t have a project idea in mind when I ordered them, but they’re so cheap that I figured it would be would be nice to have lying around if I did come up with something one day. I’m still drawing up a plan, though I think it’s only natural that I try to use that temperature sensor that was originally destined for the ESP8266 project. I haven’t done enough research to see what is and what is not doable with this pair so I can’t confirm anything just yet.

bbIn the ESP8266 project, I have three mini-breadboards that each have a main purpose on them: One for my AMS1117 power regulator, one with the sensors, and one with the ESP8266 module. I decided to try and combine two of them so I could free up one so I could use it to play with the RF pair. I managed to cram the AMS1117 and ESP8266 onto one mini-breadboard… As long as it still works, it’s fine. I hope that this project will be on a perfboard soon anyway.

74HC595 Shift Register Boards Rev B / Light Show 7

I hadn’t mentioned it before but I sent the next revision of my 74HC595 boards to get manufactured and they are on their way to me right now. I’m pretty excited to see how they turn out because they are my first manually routed board.

I’m also excited because it’s part of some upgrades I want done to the Light Show Project before I start programming a new show. These new shift register boards break out the Output Enable pin which allows for some PWM control. The backdrop will definitely have that, but I’m also considering having all LEDs in the project controlled by shift registers, including the fountain LEDs which have always been controlled directly from the Arduino. There are advantages and disadvantages to that but, either way, I plan on taking a close look at how everything is wired.

In addition to working on the wiring, I’m still looking for ways to make it even bigger. For every version of the show, I watch the show and pick out things that I want to focus on. What I realized with Light Show 7 is that it’s not designed very well to watch on a widescreen… We’ll see what comes of that.

 

Thanks for reading! Stay tuned for more!
