Actual lyrics to "Awaken the Giant" by Stratovarius

I like the song "Awaken the Giant" from the 2003 album "Elements Pt. 2" by the Finnish band Stratovarius. It's one of my favorite motivational or inspirational songs. So I decided to look up the lyrics to it on the web. I got plenty of results, most of which included a typographical error, "munst" where I was sure it should be "must." So I decided to listen to the song and compare the actual lyrics to the ones on the web.

Unsurprisingly, I found more errors. Surprisingly, some of them (including "munst") came from the "official" version of the lyrics on the band's own web site! So I listened to the song a few times and pieced together these corrected lyrics, which I believe to be closer to the words that are actually sung than anything else you'll find on the web. Just another public service. ;)

I'm staring at the wall, sick and tired of all 
Manic depression makes me small; it makes me crawl 
I need some peace of mind; the pressure makes me blind 
The labyrinth of pain, the exit I must find 
It's all inside of me, the answers lie within 
And all that I can win I take for myself 
I'm the one who holds the key to all that I can be 
My spirit yearns for truth; it's learning to be free

Through the years, I was doing things the wrong way 
But now I've changed, it is time to say 

Awaken the Giant; don't let him sleep 
Awaken the Giant; look deep within 

I won't give up the fight, until I see the light 
I won't give in to the gloominess of life 
The end is in my sight, in the middle of darkest night 
I see my future's bright; I'm reaching for new heights 

Through the years, I was doing things the wrong way 
But now I've changed, it is time to say 

Awaken the Giant; don't let him sleep 
Awaken the Giant; look deep within

Inexpensive Night Intervalometry with the Digital Rebel XT

 I recently discovered two interesting things:

  1. Canon's TC-80N3 intervalometer ($130ish) makes it possible for their mid-range (EOS-20D, EOS-30D) and professional (EOS-5D, EOS-1D) digital SLRs to take exposures at timed intervals.
  2. Canon's low-end digital SLRs, including the Digital Rebel XT (EOS-350D) I use, are not compatible with the TC-80N3, and third-party solutions like the Zigview R are quite expensive ($250+).
However, whilst poking around last night, I pieced together three other facts:
  1. The Digital Rebel XT supports the RS-60E3 ($20ish) remote switch, which I have, for "bulb" releases to prevent camera shake, or to arbitrarily long exposures.
  2. The XT does timed exposures up to 30 seconds, and can do long-exposure dark frame subtraction for anything over 1 second at ISO/ASA 1600 or anything over 30 seconds at lower ISO/ASA settings, taking as long for the subtraction as it does for the timed exposure.
  3. The XT has a "motor drive," and will cheerfully take one shot after another.
So I plugged in my RS-60E3, set the XT for ISO/ASA 1600 and 30-second timed exposures, with dark frame subtraction on, found an aperture that kept things from being too bright, and locked the RS-60E3 in the "on" position, just as I would do for a "bulb" release longer than 30 seconds.

It did a 30-second exposure, followed by 30 seconds of dark frame subtraction... followed by another 30-second exposure, followed by another 30 seconds of dark frame subtraction... I walked away and let it do its thing.

You can see the results of this in two short time-lapse videos I made:
Giant Space Laser Time-Lapse
UH88 timelapse

Each of these is about 36 minutes of real time, at one exposure per minute. Tonight I hope to put together some significantly longer time-lapse sequences. I may opt to leave out the dark-frame subtractions, to get 2 30-second exposures per minute, or I may go with a wider aperture and use 15-second exposures... wait and see.

So, basically, if you're willing to limit yourself to taking N-second exposures every N seconds (or every 2N seconds if is 30 or you're using ASA 1600 and N is at least 1), the XT and its cheap bulb release provide some basic intervalometer functionality. It's not terribly flexible, and the requirement for long exposures makes it pretty useless during the day, but in the dark of night, the results can be quite nice.

This may also work with the original Digital Rebel (EOS-300D), but I don't have one of those to try it out on... anybody have one, and an RS-60E3, and want to give it a try?

Why I'm leaving Twitter.

I've stuck it out and continued participating on Twitter while Elon Musk has run it into the ground, made it progressively more inhospit...
