Yup, it plays the Somerset Wassail!
It still needs a set of pushbutton controls and a wooden case, but it’s finished enough to play tunes.
Here’s the story since my previous post:
Using the jig I made, I routed out the vertical slots for the solenoids:
Then (badly) routed the horizontal slots. the vertical slots keep the solenoids from twisting or falling over; the horizontal slots keep them from slipping down.
Here’s a test, putting one solenoid in its place and holding it with a cable tie.
I then adjusted the height of the solenoid bar so that the solenoids would have room to hit the chimes. I tested the height and position (left-right/top-bottom) with a ruler so that the solenoids would hit the centers of the chimes.
I then soldered a length of speaker wire to each solenoid (with a heat-shrink cover over the solder joint)…
…then crimped on a Molex connector on the circuit end so that I could plug it into the breadboard.
Here’s what the chime looked like in mid-construction:
Once I’d added all the solenoids, I placed the chimes on the board and voila! It played Somerset Wassail.
In my next post, I’ll use the Open Source Aria Maestosa to write up a few more public-domain carols.
