Windows 8 audio clicks and glitches narrowed down to Malwarebytes

Ever since I got my Windows 8 PC, I have been having serious problems with audio.  Basically all sound playback on my system experiences a brief  but frequent click, skip, glitch, stutter, whatever you prefer.  I can reproduce the issue on any sound card or firewire sound interface (devices tested include the onboard Conexant SmartAudio HD, my external Phonic Helix 12, and my Edirol FA-101).  All of them seem to have audio clicks, with the firewire interfaces' clicks seeming more harsh for whatever reason.

Crock Pot modification

One of the neat things we got as part of our Christmas haul is a Crock Pot.  I've been wanting one for a while, and it was really perfect timing.  We've already made quite a few dishes in it, and it's been going very well.  One thing that kind of sucked was that one outlet in the kitchen (apparently) doesn't work, and it took an hour to find out that the Crock Pot wasn't cooking.  There is no power light on the device anywhere, and the only way you know anything is happening is by the surface getting hot, which either takes a long time to do so, or is so hot that it will burn your hand.  Besides these lengthy guessing games, it's a safety concern when there is no visual indication that the thing is so hot you can't touch it.  Not really ideal. To complicate matters, I also invested in a simple outlet timer that would shut off power to the cooker in case no one was home to do so.  The timer I got also lacks any sort of on/off indicator, so it's e...

Repairing broken Kurzweil keyboard

In for repair we have a Kurzweil 88-key K2500X, with weighted keys.  This beast weighs about 80-100 lbs. It had reportedly fallen off a keyboard stand.  It came in with several "sticking keys", one chipped key, dented front, and a broken end cap.

Unleash Your Galaxy Nexus Screen: Tweak Auto Brightness

When I was shopping for my next phone, one of the main selling points of the Galaxy Nexus was its beautiful SuperAMOLED screen.  Because the screen pixels are actually light sources (as opposed to a more traditional LCD in which a backlight is filtered by an LCD screen), the contrast ratio and color vibrance are theoretically unmatched.  So why is it that, weeks after getting my long awaited gem, my assessment of the screen is that it is more lackluster than my 3 year old Moto Droid? The answer lies in the combination of two factors: Different colored LEDs respond differently to various power levels, in terms of their brightness. The default screen-brightness-to-ambient-light mapping offered by Ice Cream Sandwich on the Galaxy Nexus (in auto brightness mode), is inadequate. Here's the proof:  Turn your display brightness all the way up instead of using auto mode.  The screen looks beautiful, the colors are vibrant, and the promise of the SuperAMOL...

Do this simple mod to your OEM Droid dock, take police style car camera footage.

You see the craziest things driving down the road in Vermont. The other day I was driving over a mountain in a snow storm, and thought about how now one would believe what I was going through unless I had some video. Unfortunately, the last thing I was going to do was try to hold a camera while driving, rally-style, through heavy snow. I glared at my Droid, perched in the perfect position to record the view out the front windshield. All I would need to do was hit the camera button, and hit record! But alas, the Droid dock has no hole in the back for the camera to see through. I vowed that day that I would take the 5 minutes to drill the stupid thing, and easily open up a whole new world of hands-free video footage.

Fix for X-Lite -> Asterisk DTMF issue

If you use X-Lite with an Asterisk system, as I do, you may notice DTMF codes sometimes don't work after the call has been placed. This results in difficulty when entering pin codes, dialing an extension on another system, etc. Here's the quick fix inside X-Lite: Go to menu -> Advanced System Settings -> DTMF Settings -Change to DTMF Force Send In Band: Yes -Change to DTMF Tone Length in Samples: 4960 Reconnect the call and try it.

Quiet Your Rehearsal Space on the Cheap

Build your own acoustic tiles for under $100 (This post is aimed at improving a band rehearsal space, but could also apply to a home studio or home theater) Have you ever jammed in a room that just seemed disagree with every instrument? The vocals are difficult to make out, the drums seem too loud, and you're constantly battling the sound board to keep feedback at bay. If this sounds familiar, you've probably experienced jamming in an underdamped room. Bare walls can cause excess reverb, and lead to a host of problems- feedback, bad equalization, and other poor conditions that make it difficult to get any work done. The easy way out is to hang a crappy old rug on the walls... And while you're at it, why not break out the cheap beer and a Playstation for the full dorm room effect. However, if you want to do it with a little more style, you'll want to use 2'x4' or 2'x2' panels. While the pros will charge you upwards of $500 for such acoustic panels,...
