m'inscrire sur un site de rencontre gratuit Loads of Braun Nizo super 8 camera owners, especially of the 400, 500 and 800 series have the problem of not being able to get their hands on 2 button cell batteries of 1.35V each. Together feeding the light meter circuitry with 2.7V. The original PX625 Mercury button cell batteries aren’t produced anymore, I guess for environmental reasons. They provided a 1.35V voltage. Nowadays the 625 batteries provide 1.5V.how much does clindamycin cost at walgreens
http://www.mabnapouyesh.com/dfdf/7303 The problem is that we have had quite some reports of owners using 2 cells of 1.5V each, thus providing 3Volts to the circuitry. This would give different light meter results so ideally one finds a way to provide 2.7V to the circuit without having to worry about button cell batteries in the Nizo.voltaren retard 100 mg diclofenac natrium

Other solutions involve using Zener diodes and creating adapters from PX625 batteries that hold the zener diode and can house a smaller cell battery.cialis 20 mg avec ordonnance

rencontre hommes serieux marmande Do connect this circuit to some power source like a 9V battery and adjust the trimmer such that you can measure 2.7V at the yellow output lead (use a multimeter).
http://vagnvagensbygg.se/firmenit/1129 One way of adding the circuit to your Nizo camera is to first hot-glue all leads and solder to isolate them, open up the side of the camera (4 screws), solder GND and Vin and the 2.7V output to the correct contacts on the Nizo circuit board and place the circuit as shown below (Nizo 801 case but other cameras should be similar):

Currently we are exploring a different way to add this circuit to the Nizo camera and that is to solder it together just tight enough that it will actually fit within the original button cell housing. One would have to take out the metal strip at the bottom of that housing, then 2 little holes are available. Through one of these holes one can put GND and Vin leads (have to be soldered to the right contact points within the camera, and the 2.7V output lead can be guided into the camera using the other hole. This method will be tested and instructions and pictures will be provided in a next post.
