Daguerreotype dispenser

Published by under darkroom,Technology

I have added a image gallery of my portable darkroom to the technology galleries. The trailer was designed to keep chemicals out of my vehicle, garage and house while letting me take the process to people and locations. It has a generator for power but also can be hooked up to household main supply, which powers the fan of the fumehood, and runs the buffing tray warmer, lights and appliances. It has two skylights which have amber acrylic for safelighting, one of them removable. Two 10 liter tanks provide the water supply, one for tap water, one for distilled and 20L waste water storage. The construction of the enclosure is with 50mm insulated panels which keep it cool in summer and warm in winter.
The quarter plate and sixth plate shown below are from a recent outing.

French revival

Published by under Fuming boxes,Technology

Mike Robinson has shared some images of his revival of a 19th century French design for half plate fuming boxes. The compact boxes feature a bottom pressure plate similar to a printing out frame back, to keep the iodine dish in contact with the ground glass. Mike explains that since the brass is on the other side of the wood from the iodine it doesn’t suffer from corrosion. The glass tray is flat pieces of glass glued with marine epoxy which is holding up well. The copper runners ensure the ground glass cannot be accidentally withdrawn and the whole design is very compact for the traveling daguerreian.

The death of logic

Published by under Technology

Veteren daguerreotypist Ken Nelson recently sent in the sad news of his recent loss – the temperature controller for his mercury pot. “Dr. Fuzzy” got his name from his brain, a Love Controls 1600 Series Fuzzy-Logic Temperature/Process Controller. Obituary by Ken:

“Dr. Fuzzy”
5/13/96 – 8/24/10

After acting quite normally yesterday, Dr. Fuzzy failed to wake up this morning. All attempts at diagnosis and resuscitation failed. After two hours of attempting to revive him, he was pronounced dead at the scene at 12:40 p.m. All possible indications led to those solid-state areas where there is no possibility of access or intervention. Probable cause of death, as Meg put it, “a massive stroke.”

It’s comforting to me that he apparently died in his sleep. I will miss him. He was the quiet, steady, reliable type, a quick study of his own life’s mercurial ups and downs, though he was by nature a bit of a control-freak.

In lieu of flowers, please send any donations, in memory of Dr. Fuzzy, to

Updating us of the progress Ken writes:

Dr. Fuzzy’s new brain arrived a few days ago. He’s currently in surgery for the transplant, but it might be a while before he goes to school to relearn his process. If any daguerreians out there are going to go electric and are looking for a reasonably economical temperature controller, look to the Love Controls Division of Dwyer Instruments The model number is Love Controls 16C-3. It’s a relay model that can handle a heating element that draws up to 5A at 250V AC. Input voltage is 100-240 V. I’ll keep you posted as to how well it works in my process. And, the tech support and customer service people at Dwyer are absolutely first-rate.
