I have an image of one here: http://www.flickr.com/photos/84221353@N00/2070548868/
Unfortunately the actual thing is in storage at the moment, so I can't answer anything that's not obvious from the...

I've scanned a couple of pages of flashbulb data here: http://www.flickr.com/photos/84221353@N00/2677558640/ and here: http://www.flickr.com/photos/84221353@N00/2676741407/in/photostream/

is that Okenfuna book the same as this under another title?

I just had that out from the library, and it's flat-out amazing.

I seem to recall that he considers the photographing of the pieces as an integral part of the art, not simply as documentation of a performance.

I had fun, and learned a lot building mine. It's a bit of a commitment, though, and not something you'll just throw together in a weekend. It does take a bit of care to get everything fitting right-...

Lee Valley has some leather strap hardware that might work:

Here's the heatsink I've been playing with- it seems sufficient for having the LEDs on all the time, so it would be more than sufficient for an enlarger, which has a shorter duty cycle. It runs at...

The datasheet on thermal design states:

A LUXEON Flood should be mounted to a heat sink before
being illuminated for more than a few seconds. A flat
aluminum plate with an area of about 36 in2...

It's true it's not a beginner project, but it's certainly doable by a dedicated do-it-your-selfer.
There are lots of affordable and fun programming tools out there, it's not like a decade ago when...

What determines the requirement for heat sink is the power of the led. Small LEDs such as the ones on the Peggy board, each dissipate roughly 60 milliwatts. While a greater portion of this power is...

I've thought about this a bit more, and looked more closely at the Peggy design- it works by switching one row of LEDs on at a time, so the total brightness is not the same as having it all on at...

The trick with LEDs is that they require the current to be carefully limited. They're really not like a lightbulb at all- if you want to dim them, you must use a PWM scheme, as in the Huws circuit....

And you didn't even have a Mountie in the shot? :)

I get "Is this going to be on TV?" a lot. Which is odd, since these days a big sneeze will probably attract a satellite truck or two, you'd...

Interesting. Thanks! That's definitely worth a try. There are sleeves of loosely woven nylon material used for bundling cables together that might also work for this method, if i can find a large...

It's a clever method for developing sheet film in a roll-film tank:

@alan davenport- that's what I fear...

Thanks- yes, getting cheap ones is no problem, but I'd rather reuse them if I can, rather than going to the dollar store all the time. I'm going to try plain rubber bands, also.

Silly question- I'm trying out the taco method, and was wondering, for those who use the fabric covered hair elastics, if there's any chance of contaminating developer with re-used elastics. I'm...

Enough people that it's a viable business model! Heck, that's considered expensive these days, many folks expect images for free!

One has to take the view that the user agreement is a contract. If you don't like the terms, don't sign it. I much prefer to do business with a company like flickr, which at least pays some attention...

I'm willing to at least take a look at the shutter- while I'm by no means a professional repair person, I've overhauled a few shutters on my own gear, and I live fairly close to the school. I think...

Anyone want to bob for "apples"?
I used to work in a TV station where we had one of those scissor-folding stands that undertakers use to move coffins. We used it to move large pieces of equipment,...

And the hills would be hopping with jackalopes, and the lochs swimming with monsters.

Actually, Ansel Adams painted his negative to remove the initials of the town Lone Pine, which were spelled out in white rocks on a hill, and would have otherwise "spoiled" his photograph Winter...

Those are lovely images, btw.

I'd probably be up for a Toronto meet. Leslie street spit is always fun, if you like bricks.
