Re: [Frameworks] Bolex EL Power question
> Ooof. Sorry, I was imagining a battery belt. Sorry, I think my info is bad. Any NiCAD/NiMH battery is made up of a number of individual cells, whether it be configured as belt or brick. !2V almost always = 10 cells at 1.2V ea. The only kind of battery that comes as one big singular thing is Sealed Lead Acid, essentially a miniu-version of a car battery. I doubt Bescor ever made one of those, but I'm not sure. ___ FrameWorks mailing list FrameWorks@jonasmekasfilms.com https://mailman-mail5.webfaction.com/listinfo/frameworks
Re: [Frameworks] Bolex EL Power question
If it shows as charged, and then runs the camera at all just not well, does it still show as charged after that? A bad cable would likely produce intermittent power, not weak power. . The thing to do is isolate the source of the problem. Don't go out an get your battery recelled until you figure out what's going on. 1) Find something else that runs on 12V, and see if the battery will power it: how well, how long... A light is good, if you have one, as it should draw down the battery at a similar rate as the camera. Anything that's just electronic doesn't draw enough to make a good test. 2) See if another 12V source will run the camera. You can jury rig it to a car battery, for example. If the camera has been sitting a long time, it could be 'stuck' and in need of a CLA. The source needs to be apply to supply the minimal current to run the camera, about 1A (1000mA). There is no such thing as a source with too much current, the device only draws what it needs. (The thing you can't go over is Volts, but few devices are that picky, so if you're a little over you'll be fine, e.g. a 14V supply is highly unlikely to burn out a 12V device -- e.g. in emergencies...) Battery capacity is rated in Amp/Hours, i.e. a 3.4AH battery should supply 1 Amp for 3.4 hours. .. The battery tech used in any older 16mm camera is old, old, old. The cells would be NiCAD's, which have low capacity, discharge quickly on the shelf, are subject to the dreaded 'memory effect', and are environmentally toxic beside. If you get a battery re-celled, NEVER get it re-celled with NiCADS!!! Replace the cells with NiMH (Nickel Metal Hydride) cells, preferably the low-shelf-discharge variety. If you can't find the same cell size/shape as the original NiCADs for any kind of external battery, either improvise, or if that doesn't work, just chuck the whole thing and get something new. You can make a DIY belt pretty easily for a lot less than anything you can buy. If you do re-cell a NiCAD pack with NiMH, you'll need a new charger. NiCAD and NiMH chargers have slightly different electronics, and a NiCAD charger probably won't put out enough current to charge up the NiMH cells anyway. ___ FrameWorks mailing list FrameWorks@jonasmekasfilms.com https://mailman-mail5.webfaction.com/listinfo/frameworks

Re: [Frameworks] Bolex EL Power question
How old is the Bescor belt? It may need recelling. I know Bescor makes those belts that have a builtin output cable, which is usually kindof skimpy compared to a four pin xlr type cable, so it could be cable damage. NiCad batteries sometimes indicate a full charge and then suffer from lack of power if they are methodically discharged. Those batteries are best not used only a little bit at a time (100ft roll, for instace) and then fully recharged. They begin to develope very short charge life when that happens. Not sure what your process is but sometimes a NiCad in decent shape can become "lazy" very quickly from this. Best test is to try your camera with another power source to make sure it isn't the Bolex. Good luck.

Re: [Frameworks] Bolex EL Power question
What does the charge meter do when you turn the camera on? Don't worry about what it does when the camera isn't rolling, worry about what it does when the motor is on. If you have left that AGM battery on the shelf for a year or two without keeping it charged, it will be time to replace it. --scott ___ FrameWorks mailing list FrameWorks@jonasmekasfilms.com https://mailman-mail5.webfaction.com/listinfo/frameworks
[Frameworks] Bolex EL Power question
I own a Bolex EL and having battery problems. I have a bescor LCR portable rechargeable batter 12 volts 3.4. It charges up fine and the camera indicates that the battery is charged. However it will not advance nor can send power strong enough to transport the camera when loaded wiht a 100 ft daylight spool. Any advice from someone on the list is appreciated.

[Frameworks] ANALOGICA 2014 /// 26.27.28 sept /// Italy
Dear Frameworks if you are in Europe next week, around the Alps in the Dolomites area, ANALOGICA 2014 could be a good place for you. ANALOGICA, the festival for analogue technology, is conceived and organized by Resistenza Analogica as a natural follow-up and evolution of the many screenings made during the past years. The festival takes place the last weekend in September and showcases a selection of: cinema: super8 and 16mm films photography: analog shots and camera obscura works music: vinyl and magnetic tape DJs, live music using analog electronic instruments ANALOGICA is an opportunity to learn about analog technologies of all kinds: film, photography or sound. Discover new (and old) ways to reuse and experiment with these uncontrollable materials that resist the standardized digital world. ANALOGICA also aims at being a point of reference and meeting place for the world of creative analog technology. The festival is a meeting point for enthusiasts, experimenters and researchers dealing with slow and low-fi technologies. ANALOGICA's first editions have been run in the city of Rome in 2011 and 2012. In 2013 the festival moved to the South Tyrolean mountains. ANALOGICA is a free-of-charge and self-financed festival.
