Mini Treble and Bass Clef Lights by ChimeraDragonfang Mini Treble and Bass Clef Lights by ChimeraDragonfang
So many people asked about buying the Treble and Bass Clef Lights at NM Brass last year that it was decided to make some tiny versions of them for sale at the 2015 national championships.

The bases are aluminum project boxes with slots cut out to fit the acrylic panels and power switches. The slots were lined with fabric for a snug, scratch-free fit that allows the acrylic panels to be removed for easier transport/storage. On the inside everything is held in place with craft foam contact-cemented to the aluminum casing. (Why contact cement? It's less permanent and easier to clean off than superglue or epoxy, in case anything ever needs rewiring/replacing. And it doesn't take hours to set.) The wires run through cut-outs in the foam, the acrylic sits snugly between two pieces of it, and the breadboard+LEDs slot into another recess trimmed to size. The lighting is simple one-colour LEDs powered by a 9-volt battery. Everything is pretty crowded and I just barely managed to fit it all in there.

Time Spent: Two or three hours for all of the engraving. Another two hours to mark and cut the slots in the aluminum casings, and file it all smooth. Maybe one hour or so for all the electrical work. Then I spent somewhere around four or five hours putting it all together because of a lot of trial and error figuring out just how the hell I was going to get everything in those small metal boxes.

Future mini-lights will take much less time now that I know what I'm doing.

Tools & Materials: 6mm-thick acrylic sheet cut into 5cm x 10cm pieces, scroll saw, sandpaper, buffer, buffing compound, computer, printer, paper, clear packing tape, permanent markers, Dremel, assorted engraving and cutting burrs, calipers, small steel rulers, screws, screwdriver, breadboard, blue and red LEDs, teeny little resistors, wire, battery clip, power switch, soldering iron, lead-free electrical solder, heat-shrink tubing, storm-proof lighter, craft foam, craft knife, 5-minute epoxy, contact cement, 9-volt battery.

These are for sale all sold. Note me if interested in ordering one of your own

These are very, very cool.

Aren't they? :la: So happy with the end result. Next up (for very large definitions of "next" because project pile) is to make more in a bunch of other colours. And some colour-changey ones if/when I can get individual RGB LEDs with lower power requirements than the strips I have right now.

Yeah...they be awesome!  If you have a version of Botcon over there you could make a killing with glow symbols too.

There's Auto Assembly in Birmingham, UK, which is probably the closest thing to Botcon or TFcon that we have in Europe. I recently completed two other LED signs featuring the Paragon and Renegade symbols from Mass Effect. Rest assured Transformers-themed LED signs will probably happen eventually. :B
