Well, I'm going to keep this short, because I just want to assure everyone that I'm still here. I'm just struggling to keep using this website. I have a choice. I can either tear it down and rebuild it with some other technology, or I can limp along with it as is. The thing is, I really like the way this website is now. I don't want to try to recreate it, even though the underlying technology has moved on . . . quite a long way . . .from where it was when I built it. So, even though writing and posting is a pain here, I still like the form. So a couple updates:
It’s been a while, huh? The last time I put out an update, I had finished getting the clock and the screen attached to the microprocessor board. Prior to that, I had hooked up the two sound boards and wired some basic speakers in place. This time, I’m going to describe how the touchscreen user interface is laid out. This was a long, iterative process, but I’m just going to describe the features as it ended up. (perhaps with a couple of asides about other things I tried in certain areas.)
OK, to reiterate where we are in the build of this Smart Weather Lighthouse build, up to this point I had configured the sound files and sound boards to play when triggered, and powered on and loaded Circuitpython on the Metro MX board. Up next, I'll go through how I got the 4.7" touchscreen attached and operating. And then talk about getting data back to the Metro board using the OpenWeather API, and finally, attaching the clock.
So far, I've described the overall idea for the smart weather lighthouse, and what the various systems of the build will be, but let me lay out the stages to this build . . . since it is a bit complicated. These are the steps I went through to pull it together:
I have to say that I couldn't have pulled together all of the electonics and coding without the excellent support of the Adafruit projects and learning pages.
I started off as I have typically done lately by opening up a gridded notebook and making some drawings. I needed to understand the typical sizes of these coins, and how many could be places in a certain area. I understand the coins are made by several companies and are usually of very high quality, including fine metals, engraving, enameling, and while many are round, some are odd shapes. So I needed to accomodate a variety of potential coin types.
Most coins are between and 3 and 4 mm in thickness, and around 4.5 to 6 cm in diameter. (1.75" - 2.0")
I opted for a simple board tray with multiple row slots for the coins, and a riser mounted at the back to lift it to create tiers. Overall, it was going to be about 12" wide, 6" deep, and about 2 1/2" tall. (30cm x 15cm x 6cm)
