I know, this is like tricking out a Ford Taurus Station Wagon. But hey, sometimes you just gotta work with what ya got. And I got a pair of 3700s. Besides, this flash is 20+ years old. I figured if I killed it doing this that would give me a good excuse to buy a new flash, maybe something built in this century : )
(When I first got into photography I chose these over a 283 because they had the same power, but they also had the 'Interchangeable Dedicated Module. At the time that sounded very impressive. Oh well, live and learn).
After reading all the posts about modding the Vivitar 283's for Variable Power I thought I'd try something similar with a Vivitar 3700 Flash. From what I've read Vivitar does make a Vari-Power Module for these flashes. But I have NEVER seen one on either ebay OR Google.
It was quite simple. I mounted a Closed-Circuit 1/8 Jack (Radio Shack Part # 274-0248) in the 'module'. I spliced it into the two wires going to the sensor on the front. The closed-circuit jack interrupts and re-directs the circuit. (Think about the stereos and boomboxes where the speakers cut out when you plugged the headphones in.) I connected the red wire (which I presumed was the 'hot' wire) to the switched side of the plug.
Then I mounted a 100k pot (Radio Shack Part # 271-0092) in a small Radio Shack Project Box, attacked a length of speaker wire to the pot, attached a 1/8 plug to the other end of the wire. And I now have a removable Vari-Power Control.
With the control unplugged all the settings on the flash work normally. When I plug the control in I get variable power from full power to about 1/64 power (or so it seems with a quick test).
As the jack is wired into the sensor unit on the front of the flash I have to set the flash to one of the 'auto dedicated f-stop' settings on the back. (This module has three of them). Then I can use the control unit and adjust the power from the auto f-stop selected up to full power.
Here are some of the Flash Meter readings I took with a Sekonic L-508 Zoom Master Meter:
(Set Up- Flash and Meter set to 100 ISO. Meter about 5 feet from flash. Flash powered by a Quantum 1+ battery. 10 seconds between flashes. Fired via Cactus V4).
(Try this with your own flash. See exactly how accurate those 'Auto' settings are)
With the Control Unplugged
Flash - - - Meter
Setting - Reading
F/2 - - - - - F/2
F/4 - - - - - F/2.8
F/8 - - - - - F/4
Full
Power - - F/16
1/16
Power - - F/4
With the control plugged in and the flash set to the auto F/2 setting:
Dial all the way left - - F/2
Dial all the way right - - F/16
At various settings in between I got the expected range of power somewhat consistent with where the dial was set. Just over half way I got F/11. So all the lower stops (F/2.8 - 8) were in the first 1/2 turn of the dial. I haven't taken the time to pinpoint where on the dial each stop was yet..
I repeated the tests with a piece of black tape over the sensor just to make sure it was not active with the control plugged in. With the control unplugged and the flash set for F/2 I would get a full power flash if I covered the sensor. With the control plugged in it made no difference if the sensor was covered or not.
I would presume this would work with just about any flash. If you decide to try it I offer no guarantees on your flash if it dies when you do this.
A fairly common fault.. the ears encourage you to wind the cable around them. Except if you do it every work day, it only lasts a year, and then it's another AU$149 for a new one.
.. or a $12 box, some heat shrink and a salvaged IEC socket, and some wire to fix it

I use my iPhone to SSH into my computers at an Internet Cafe. All the computers run a form of Linux or Mac OS X.
I have AJAX enabled webcams to view in Mobile Safari. If there are unruly customers, I can easily run "init 6" and reboot.
Pretty incredible. The Iphone is a great remote admin tool.

No but seriously, sticking your favorite speaker-havin’ media player inside a glass with the speaker facing down is a good way to get louder audio (and in terms of “better” the iPod/iPhone “Loudness” EQ setting does wonders).
This is my MacGyver hack on my desk chair that's falling apart. I tried welding the plastic together to no avail. So, I went with this wood screw and coat hanger hack. Surprisingly, the chair has never been in better shape since I inherited it.

Groups of hackers sit around waiting for the staff to mop up the rain, get the roof to close and let us back in to continue to hack. Anyone got some spare internet connectivity?

Should Canada host an American wanted on child-pornography charges in Tennessee? He fled to Canada earlier this year with his parents and sought refugee protection, claiming that he faces the possibility of persecution back home because of his affiliation with the online hacking group Anonymous?

Those copper brewing kettles are still in use. There were about ten of them in this room, one next to another. It was so warm.
And it smelled awesome!
