IMG_5307aAs part of my continuing tinkering, I have provided an external power jack on one of my TL120 cameras. The full story gets its own page.

The camera can now accept power from any external battery which can deliver between 5 and 32 volts. Long exposures and cold temperatures are no longer things to be afraid of. I’m planning on using a 12v lithium from a cordless drill. It should be able to deliver the goods even when the temperatures fall below freezing.

newbatterycoverOver the years, there have been many comments on the mailing lists about the batteries in the TL120 camera. Over the years, I have measured and offered suggestions about these concerns. I have recently done more measurements and collected my information onto a single page.

Summary: The button cells used in the TL120 are not a very good match for its requirements. But since the camera is designed to use them,

  • Use SR44 batteries
  • Do not use LR44 batteries
  • Keep a set of PR44 batteries in your camera bag as backup

Almost on a whim, I decided to look and see what was inside my TL120 camera. And since I was going in, it seemed like a good idea to take pictures and document it for the next person.

You can get your camera, a pair of tweezers, a couple of screwdrivers, and follow along!

There are a lot of pictures and process takes a lot of space to describe, so it gets its own page.

There have been twinned Holgas in the past (holgamods.com offered one for sale).  But at the 2008 Photokina, Universal Electronics Group actually displayed a pair of stereo cameras.  Stereoscopy.com had this to say (and a photograph of them, too):

This company is exhibiting two pre-production models of Holga Medium Format Stereo Cameras.
One model, the Holga 120 GCF 3D, has a 67 mm stereo base and an image format of approximately 54 x 53 mm (HxW). The lenses are cheap 1:8 f/60mm lenses
The second model, the Holga 120 PC-3D is a pinhole camera, with a pinhole of 0.3 mm and f 135.
Prices and availability are not known yet.

Anyone who expects these to have sharp lenses or light-tight bodies is probably going to disappointed, but they could still be fun to play with.  Since Holgas sell for $20, maybe these will go for less than $50.
