Fixing Logitech trackball performance

I love these Logitech Marble Mouse trackballs, I have one for every computer.  After a few years they slow down physically.  Cleaning the dust off does not help enough, something different needed to be applied.  I’ve been researching lubricants and oils, doing some tests with households; but I think I’ve found the perfect fluid.  Ian Gomes of Union Sound Company made a recommendation a few years back for Penny and Giles faders.  A quick amazon search lead me to Lucas Silicone Shock fluid.  I must report that it is the perfect product for this application.  If you need a drop, I’ll send you a q-tip of it in the mail.

Joel Plaskett rocking some WBS pre-amps

I was reading http://professional-sound.com/ (like I do every month plug plug) and saw Joels lovely new studio and Neve Console.  Front an centre I was happy to see the set of WBS pre-amps I wired up for him a few years ago.   Glad they’re making great records! And congrats to Thomas, who was apparently a regular at Revolution Recording… I just kept my head down and in the backScreen Shot 2014-08-21 at 1.48.31 PM Screen Shot 2014-08-21 at 1.48.56 PM

A Social Experiment

I’ve been thinking about a social experiment.
I often take calls from people looking for services, I’ve met a lot of great people in this industry and I do stand by their great work and contributions.   So instead of fielding calls and answering the questions I’ve created a Wizard Services section at http://audioaholics.com/wizard_services

I am asking you my friends to use it to work, get work share work and do work together.  I would like to consider it my rolodex

I’ve got the permission to post a few contacts and will be doing so this week.

Adapter of the day

I was doing a gig on the weekend and was Introduced to an adapter that saved the gig. We had an in ear monitor that was buzzing, the feed was coming from the truck line level from the output of the clear-com. Right from the truck, at the panel on the outside, there was noise in the cue box. So instead of feeding that line level from the truck I thought it would be nice to send an IFB (clear com) to a TR-50 then Sennheiser IEM transmitter at ‘somewhat line level’. The truck engineer said “Hey there is a clear-com to Line level adapter in the truck, a Drier” Lo-and-behold it saved the feed and delivered a perfect noise free signal to the talents IFB. If anyone knows what’s inside please let me know, kinda curious.

We added a transformer for added isolation.

It’s not to dis-similar to http://home.roadrunner.com/~jimirayo/drier.htm

Making a Yamaha SKRM-100 subkick

A few years ago I made another Sub-Kick. I used all Yamaha Parts… so I guess it’s a Yamaha Sub Kick

Drilling the XLR into the side:IMG_4195

Pulling the driver from its box:IMG_4196

I built some Brackets and drilled the holes to line up with the existing lug hardware:IMG_4197

Filled the lining of the shell with acoustic foam and put another mesh head on the back:IMG_4198

Urge to smash

Image

I recently acquired a new computer and have begun the “Migration” from old to new. I know it’s not a quick process (600+ Gb from machine to machine) but by my math this estimation, using FW800, was WAY OUT. The problem turns out that the computer was going to sleep during this migration!! Why the HELL would it do such a stupid thing? There were no options for sleeping as it’s a fresh install. Shame on Apple.

After three failed attempts, I had to find a solution to me sitting at two idle computers for 8 hours.

AND HERE IT IS!

I needed to be able to leave it also… so in an audio Macgyver moment of desperation I turn to my biggest fan. The cable for the Trackball is moved by an oscillating fan. The headphones are on top of an upside down trackball, this and the duct tape give the trackball some weight to push on the keyboard (for computer 1) the movement also pushes a button on a Magic Trackpad (computer 1)

so far attempt number four is going smoothly (knock on wood)
