Girl Genius Radio Theater Microphone
Jake von Slatt — Mon, 03/05/2012 - 12:16
I generally don't do commisions. But occasionally a conversation will spark an idea for a project and I'll create something like this microphone. In this case it was a conversation with Cheyenne Wright, one of the artists behind the Girl Genius webcomic and it took place at SteamCon 2009. Cheyenne, along with Kaja and Phil Foglio often perform Girl Genius Radio Theater skits at conventions and Cheyenne was looking for a microphone with the appropriate visual impact.
The project sounded interesting so I agreed to produce something, sometime. Steampunk Workshop is all about the slack, so I commit to no schedule, ever.
It's done when it's done.
In this case the microphone was done in time for SteamCon II where I was able to present it to Cheyenne.

This is how it usually starts, a pile of things I think fit together.
The core of the microphone came together pretty quickly for me.
I ordered a desk microphone stand and looked to my big box-o-brass for trim pieces.
I settled on a lamp part and a British made plumbing adapter that my father-in-law found at his town dump.
To surround the Eimac transmitter tube that formed the core of the microphone I designed some brass plates that I had water-jet cut for me at Advanced Water Jet and Engraving. This was the first time that I've outsource a part of a project and I'm glad I did because cutting, drilling, and finishing these 8 pieces would have been a tedious nightmare! I also purchased a vibratory tumbler to polish the pieces and this turned out to be another really great idea! It is soooo nice just to drop evrything in for an over-night tumble and have clean & polished parts in the morning!
After tumbling I formed rings of bronze brazing rod and assembled the tube cage in a simple jig I made on the table saw.
Here's the completed microphone.
I am very pleased with the result as is my customer, Cheyenne. At SteamCon II, Phil and Kaja also asked me to make them a microphone for Girl Genius Radio theater because, apparently, Cheyenne won't share! ;-) I've been combing eBay for a suitable tube to form the core and I'm hoping to have it ready for the Steampunk World's Fair con in March. But if not, it will certainly be done in time for SteamCon III.
The height of the mic is adjustable as well as the angle.
View from the rear.
A close up. The water jet process does leave some roughness that was not polished out in the tumbler.
Rubber "O" rings support the Eimac transmitter tube.
I installed some super-bright green LEDs in the base of the tube, these are ganged to the microphones "mute" switch so they light when you are "On The Air."
Another view of the LEDs.
The mic cord is covered with woven cloth the I removed from a length of climbing rope purchased at Eastern Mountain Sports. The line to the actual microphone element is covered with the outside of a shoelace.

Very true and persuasive
Edju — Mon, 03/26/2012 - 21:23I love the complexity and overall style of this wonderful piece. The frontal view is really amazing. What a great piece of imaginative art.
Question about the cord
firsttenormtv — Mon, 06/27/2011 - 11:10This is an absolutely superb piece and I have just one question. How did you get the woven cloth off of the rope and onto the mike cord? It seems like it would be quite tricky!

Ottawan — Mon, 02/21/2011 - 23:41I was just wondering, how did you join the ends of the brass rod rings?
Another Backup Date
Bryan J Sebeck — Fri, 02/18/2011 - 05:49You could always use the World Steam Expo as a more "in between" back up date. :)
A work of genius

I had looked into buying a
jdmorse — Sun, 02/13/2011 - 11:14I had looked into buying a water jet some time ago but decided that the resolution was not good enough for tool & die work. The other issue was the grit that is used for most metal cutting is not recyclable; which means that to make the thing pay I would fill my shop with spent grit in a month until I could get someone to haul it away. Much easier to give what little water jet work I have to someone who has one. So, is the mill not yet functioning? Those kinda parts are what CNCs were made for.
Beautiful work though; I envy your artistic eye.
The mill is not yet
Jake von Slatt — Sun, 02/13/2011 - 11:43The mill is not yet functioning, but all that's needed is for the wiring to be done, I'm hoping April will see it's completion--the main hold up is the fact that the garage is not heated!
To answer someone elses question: total cost for the water-jet parts was about $70 including material and shipping from California.
Next time
DreamingDragonD... — Sun, 02/13/2011 - 23:55Let me know when you need this sort of parts. :D
I'd be perfectly willing to hand cut and finish parts like these for a comparable price, and you'd end up with smoother work.
Heat!
jdmorse — Sun, 02/13/2011 - 15:30Ah yes, that one! I keep the heat at the shop set to 60 and we use a lot of space heaters.
$70 including material and shipping is VERY reasonable. I may get a quote from them next time I need something cut.
Wow! That's really neat. Just
septentriones — Sun, 02/13/2011 - 10:44Wow! That's really neat. Just one question, did you spray paint the microphone cap? I noticed that it went from silver to a brass.
I did. Gold with clear

DreamingDragonD... — Sun, 02/13/2011 - 01:12Sweet work on this.
As a jeweler, I'm a bit curious about how much it cost to have those parts cut?
looks amazing.
