The transistor idea didn't work, neither. I ended up just adding another output to the program.

I got this on/off circuit set up on a breadboard today. The stupid voltage divider didn't work for the LEDs, so I have to try to use two transistors to control the LEDs. They are inside of the switch, by the way. I need to really start posting some pictures up here. Here is the new schematic. I haven't bought the transistors yet, but I am going to get some at RadioShack tomorrow. It should work, in theory.
Well, I got this PIC programmer, and with the help of this guy from the microchip forums named Dario Greggio I got the PIC to act as an on/off toggle with the off action requiring a button to be held down for a few seconds. I've since designed the PCB for the circuit. If anyone is interested in the circuit, PM me for more details. Getting a quantity of PCBs ordered would bring down the cost, greatly. I will draw and post up the schematic here later.
I got it all torn down days ago. I haven't decided if I am going to get another top plate laser cut or just modify this one. I want to go with a Bulgin switch, and not in the stock location. It's in a bad location where I have the amp sit I burn myself on the tube reaching for the switch to turn it off. I have a top plate designed in AutoCAD. I'm just waiting to hear from a place about laser cutting and if I need to add any considerations for beam width (maybe someone here could help me?). I drew everything literally the size I want it to wind up. The new tube sockets are smaller in diameter, so I ended up shrinking those holes in the drawing. I will still need a few more holes to mount a board that does the on/off latching and delays the signal to the headphones because I don't feel like putting the massive effort into pressing the latch to remove the headphones every time I turn it off, and I don't feel comfortable leaving them plugged in when I power it on.
The transformer end bell ended up ugly and rusty with all of the skin oils from handling. Oh well. That's getting powder coated and it was the plan from the get-go.
I got the capacitor brackets from Shapeways today.
I bought a Crack off ebay some time ago, pre-built. It came with AΞON output capacitors. I've since replaced the RCAs with Neutrik ones and the headphone jack with a Neutrik latching jawn. The octal tube socket just plain sucks and the signal started becoming intermittent, so I took the amp out of commission and I am going to do a whole slew of things to it.
So far I'm impressed with the amp. I didn't think the sound would change that much from the on-board amp on my STX card. Naysayers obviously don't understand that impedance is only measured at one frequency point and high-impedance headphones like my HD-650s are quite demanding of power for bass. You need a healthy reserve of power to drive low frequencies. More Updates to come.
Why in the world are lenses for cameras to shoot small object up close called macro lenses? You don't look at small stuff through a macroscope! Macro- is the opposite of micro-.
Neon is a chemical element. A gas, not a color. If people still want to [incorrectly] apply it to a color, it could at least be neon orange.
This is the formula of crotches. The formula solves how many crotches something has, where x equals the number of legs something has.

The other night I had this crazy crazy dream and it's affecting my brain more than others in the past.
I was in my room and it was dark. I was trying to change settings on a surround sound receiver because it was staying on even though it was off. I look down at my arm and it looks all anorexic. I get into some light and from my shoulder to my elbow my arm is all gangrenous. The triceps and all that skin are gone, and the skin on the biceps side is already black and peeling away. A muscle and blood vein must have been still alive because everything on my forearm was OK and I could use my fingers, and I could move my forearm with my biceps. So I go outside to the garage and ask my friends brother if he can take me to the hospital and he is refusing because he is too busy. Then I wonder where my car is to find out his mom took it. She comes pulling up returning home, and hits a curb, going like 2 mph and flips my car. I flip out, and she gets all pissed at me for being pissed, despite my arm being almost gone. Then I get my keys back and I drop them on the side of the street where water is flowing from rain and my keys float away. She gets them and throws them at me. So I venture back towards my car and I keep seeing random 5, 10, 20, 50, and 100 dollar bills floating in the gutter and in people's yards, so I figure I gotta get my arm amputated, I might as well consider this money mine, I'm gonna need it. Then I head back towards my car and a bunch of hood rats are arguing with guns, but they leave me alone. I go to start my car and that's when I wake up for real.
I have dreams a lot about nuclear war and they're disturbing, but this is weird and I'm paranoid about my arm contracting some kind of infection and rotting off. I went and looked for pictures of gangrenous limbs and my dream pretty much seemed really realistic and graphic, and I never saw any imagery of that before in any form.
I am sick of how animals are classified. It is too confusing with all the Greek names. I have a simple way of classifying things. Anything that flies will be a bird. Anything on land will be animal. Anything that swims is a fish. It will also be dependent on where that creature is at said time. If a bird is walking on land it will then be an animal. An otter on land would be an animal, but a fish when it is in water. Simple.
I am getting sick of CDs. They sound like crap and have always sounded like crap. They are fine for rap and any music that uses fake computer instruments, but I listen to classic rock. Vinyl sounds better to me, and I don't care if they have less dynamic range. It is analog directly from a high resolution studio source. CDs also sound like crap because studios are making every sound the loudest that can possibly be, compressing the dynamic range to far below the theoretical dynamic range of vinyl, anyway. My solution: my own standard, using DVD media as storage. Studios would have to pass tests for that album to release it under this standard. If they don't follow the rules and just slap a name on it, they will get bombed! Metallica's last album, Death Magnetic, is a very loud album. The CD is horrible, and the vinyl appears to be mastered from the CD, with just a tad bit less loudness. The producer, Rick Rubin, gawks at criticisms about this and basically says that what he did was awesome and the loudness coincides with the type of music it is, and that only a minority complained about it. Well this may be acceptable for the CD, but to release a vinyl that sounds like crap, and for people to pay over $100 for that, this is unacceptable. That moron should be shot, but instead he was awarded a Grammy for "Producer of the Year."
The details:
An even better format would be the same thing, but on a flash memory device of 8 GB. Who gives a crap about copy protection? Those schemes get broken by hackers in hours anyway, and it's just a waste to spend additional money on things that will get hacked. Even people who download illegally don't give a crap about quality. Most everything pop music out there is just 128 kbit VBR mp3. Ripping from a source like this would make no difference to quality when compressed that much. This would be an audiophile format, and should cost a little more just to try to ward off piracy. My thoughts are that if you make good music, people will support you by buying your albums and going to your shows. No artist ever went broke from having music being pirated. If an artists cares so much about money and piracy, they suck anyway and are full of themselves.
