Thanks Merg,
I read your bio by Eric Biggerstaff and I watched your portfolios I'm impressed
When you were "Photographing with Brett California, 1971" I was 10 years old in France, close to Paris....

Hi folks,

I received this safelight from a photographer who knew Brett Weston
Do you think "Pyromania" is a reference to Pyro process used by Brett Weston ?

Thanks Tim to continue to improve this clever and useful timer !

CONSISTENCY IS THE SECRET

I am not better with this tool but my results are constant so I can improve my work
I printed some pictures this afternoon, when I started my developer was at 76. I used...

thanks
I had some simple pole spdt in stock, so I used one for choose Film or paper and the second between the first switch common wire and ground.
as soon as I open it I take pictures

In box with a foot switch, ready to use !
I added one switch to choose between Real Time or Compensated Time

I confirm, it works well !!
You can choose Film (displays are dimmed), Paper or even no compensation, bip every 30s and you can adapt the factor compensation and more

Now, just need to put in a...

Same trouble when I reverse xfmrs, I guess one is bad.
I'm gonna sell the two cold-cathode florescent lamps (thank Eric) and one xfmr, maybe someone needs these, and keep the body to try to build a...

I ordered all the parts (less than $50) to build this timer and I'm in contact with Tim, the guy who develop this project.
I'll let you know soon

It's not for LED light, it's for developer tray or tank !

High voltage but low amperage, no ?
I admit it's a weird option.
I didn't have time this week to try to reverse the xfmrs, I'll do that tomorrow
But no number, no symbol, nothing, nada

It's a very good idea.
Just need to find a high voltage switch to alternate blue or green neon since I have only one High voltage transformer in working condition

Thanks J.B
I'm gonna check this link
BTW, I love your work

Led like this ?

10w et 35w 36v

it's sentimental, as I explained before, and it's a nice challenge, no ?
I use a Heiland Led head on my Focomat V35 and a split grade head on my De Vere 504. Both are connected to the same Heiland...

No resistance between Black and red, on both. open circuit ?

tell me if these pictures work for you:

I think both primary are still energized to stay warm and ready. the red and black wires control the secondary and allow the variation of the power for the lamp.
When I turn the head on, both...

I don't see any connection between these TO220 and primary circuit for HT

there are also these component plugged in parallel, one on Power input, one one Timer input.
I don't know what it it ? A...

Good morning

No information on HT transformer, no way to open it

I unsoldered them, same value on primary or secondary, 450K Primary, 148 Ohms secondary
I think there is a...

I definitively need to disconnect primary, they are connect in parallel !!

I don't understand:

Primary (non disconnected) 68 Ohms on both
Secondary (disconnected) 148 Ohms on both
??
Same values but only one works ?

I have to disconnect primary on both to be sure...

Thanks to all for your interest

Some news:

I checked the two photo diodes, they go from 300K to 500Kohms when they are facing the lights
Same behavior for both, I think they are ok

I...

I asked Richard Ritter, he said he wasn't at Zone VI/Calumet when this lamp was designed. He don't know.
LightSources sells remplacement bulbs but I'm pretty sure it's not the bulb, I think it's an...

Hi Everybody,

I own a Zone VI VC cold head but sadly one of the bulb, the green, doesn't work anymore.
Does anyone have an idea of where I can repair this head or at least have the schematic ?...

Hi, If you plan for EST 1000, can you please send me a copy

Thanks
Pierre

HI, if you have plan, can you send me a copy please ?
