In which Max constructs a jig to hold the brass panels for his Pedagogical and Phantasmagorical Inamorata Prognostication Engine.
Wow! Things are racing along with regard to my Pedagogical and Phantasmagorical Inamorata Prognostication Engine. Now, before we leap into the fray, let's first make sure we're all tap-dancing to the same drum beat:
|Pedagogical|| = ||Educational|
|Phantasmagorical|| = ||It's pretty darned fantastic|
|Inamorata|| = ||The woman with whom one is in love|
|Prognostication|| = ||Predicting the future|
|Engine|| = ||Machine|
One way to think of this is as a high-tech, Steampunk version of a Magic 8 Ball. The idea is that I will be able to use it to predict whether or not my wife -- Gina The Gorgeous -- will be in a good mood when I next see her and whether or not the radiance of her smile will fall upon me and lighten my life.
Actually, when I come to think about this, it dawns on me that I really don’t need a prognostication engine to tell me my future, because I already know the answer to my question (LOL).
I gave a presentation about this little beauty at EE Live! 2014. (See: Bacon, Beerfest & Prognostication Engines at EE Live!.) I am happy to say that this presentation was very well attended -- possibly due to the free bacon and beer -- and the audience was very enthusiastic about my project.
So, let me bring you up to date with the current state of play. In my previous blog on this topic, which I posted just before I set off for EE Live!, I'd just taken possession of the machined brass panels. These were created for me by my friend, master machinist David Guthrie. David is the General Manager at MaxFab Precision Metal Fabrication & Machining, which is located just down the road from my office.
When I returned from EE Live! David presented me with the remaining parts -- a variety of bezels that will be used to highlight the various knobs and switches. In the image below we see all of these pieces on my breakfast table.
In the following image we see the bezels sitting on top of their respective panels. The five big holes without bezels are for the analog meters. These don’t need brass bezels because they already have their own black Bakelite equivalents.
In the fullness of time -- after I've artificially aged the brass to look like it's circa 1900 -- each of the small holes at either end of the bezels for the toggle and momentary push-button switches will be filled with a mother-of-pearl dot. Behind each of these dots will be one of Adafruit's Flora NeoPixels. Similarly, each of the 16 holes in the round bezels associated with the five potentiometers will contain one of these mother-of-pearl dots. In this case, I'll be using one of Adafruit's NeoPixel rings behind each potentiometer. And, of course, everything is going to be controlled by an Arduino Mega.
OMG! While bouncing around the Adafruit website to get the URLs for the links in the previous paragraph, I saw that the little scamps have just introduced Diffused 8mm Through-Hole NeoPixels. If I were a betting man, I'd wager that I'll be finding some use for these little rascals in the not-so-distant future. But we digress...
