CHANGES

I hope this works out as I see it today.

My health is changing.  I usually feel just fine, but the doctors are playing with me as they would culture in petri disk.

Meteredlight products are no more.  Sorry about that.  I know there are a few of us clinging to the past.  I'm right there.  Silver all the way:  film and paper.

I have remaining stock of MetroLux's, both ONEs and TWOs.  The TWOs come in black and white.  Supplies are limited.  There are probes to be had.  If you have a new lightsource or are adding another enlarger, you'll need one of these.

There are no more MRS (MetroLux Remote Sensors), Levelers, or Pocket Spot meters.

We are repairing most items.

Documentation.  I've just added the MetroLux 2 instruction manual PDF.  For this there is a link to the rangeoflight website.  Thank you Range of Light.

New things.  I've designed several new things.  An LED lightsource and controller that is relatively easy to DIY.  Also, a 'FLASHER' or pre-exposure thingy for printing and a portable shutter speed timer.  The plan is to post the schematics and the design files.  Those of you that know some electronics will have an easy time following along.  Those that don't will need to meet those that do.  All files will be open source for people to build one for themselves.

I'll be changing the old postings in the blog to reflect reality.   I hope to add the schematics for MetroLux, too, incase you wish to tinker with your MetroLux.  However, once you mess with it, don't ask me to fix it.

The End

I want to thank all for your interest in our meters and timers.

Karl and I always said we'd do this for fun and when the fun ran out, we'd stop.  With darkrooms on the wane and LED light sources, the need for a closed loop timer has faded.  We still have plenty and the deals are good.  And there are still photo diodes (probes) available, too.  Occasionally, I repair an old MetroLux. 

The Pocket Spot light meter -- well, we just don't make them any more.  My health has taken a turn.  Not sure what direction I'm going, but I have other things that must be done before I'm done. 

I have some other little electronic gadgets I've designed.  For these, I will post the schematic, simulation file (SPICE), and a picture or two as open source and you can build your own. 

Happy Snapping.
