I never had quartz clock I see you need to use carbon battery, I am thinking start with 1000 ohm resistor and see if clock runs with alkaline battery if not just keep lowering resistance.
I run all my clocks with alkaline batteries. Where did you read that carbon batteries are required?John1397 said:I never had quartz clock I see you need to use carbon battery, I am thinking start with 1000 ohm resistor and see if clock runs with alkaline battery if not just keep lowering resistance.
I'm with @anorlunda -- I don't understand your question. Do you have a datasheet for the clock you are asking about?John1397 said:I never had quartz clock I see you need to use carbon battery
A crystal regulated wall clock will run on any battery voltage from about 1.1 volts to 2.0 volts. I use rechargeable Ni-Mh cells at about 1.2 volt.John1397 said:I never had quartz clock I see you need to use carbon battery, I am thinking start with 1000 ohm resistor and see if clock runs with alkaline battery if not just keep lowering resistance.
The manufacturer in China says not to use rechargeable or alkaline batteries even Seikos website says no alkaline batteries, seems to me on DC you only have volts and amps.anorlunda said:I run all my clocks with alkaline batteries. Where did you read that carbon batteries are required?
"Somebody" is not a valid reference at PF. I checked the datasheet for those diodes and this schematic is obviously in error. Lordy.John1397 said:Somebody thinks this will work three diodes in row cuts voltage from 5 to 1.5.
