I was using the wall wart from my Dx6i. Reconnected everything the way it was before I began mucking about, and it doesn’t charge Connect two diodes in series to this wire. Can you do this Mod AND modify it to a wall charger as well? I opted to splice the wires instead of soldering directly to the board since I am not that confident in my soldering skills. I have a cellphone wall charger with an output of just over 5V Quote:.
Whether you put a resistor in series or get the right voltage wall supply set your voltage at 4.

Help with qualcomm charger modification! Cathodes stripe toward LED. Diode Mod and Battery Profile I picked up an MCX last week and thought it datasheer silly to keep expending batteries so I reverse engineered the charger, came up with a solution then looked to see what others had done.
Also I was planing to modify it to accept a wall wart as it eats batteries! Jan 09, Keep in mind ma is the absolute highest and that is only one cycle on brand new AA cells.
Last edited by markusb2; Jul 31, at Sorry for bumping such an old thread but I thought this might be of interest to some of you out there. The diode approach does not change the current profile as they only drop voltage, not limit or change the current.

I bookmarked it this time. Two diodes in series was my approach. Jan 14, Unless anyone has any better ideas, I plan on plugging the wall wart into the wall then plugging the lead into the jack. On the second charge cycle dataeheet degrades further to ma and so on. Jan 04, Images View all Images in thread.

I used some heat shrink tubing to avoid shorting anything out. Charge up to 5 batteries at once mod I thought you guys might be interested in a different type of mod I posted. The Datashset is a mystery to me. I just noticed on the datasheet for the AA transistor they state the collector-emitter saturation voltage is 2v so using 6v of alkaline AA batteries you should get a charge voltage of 4v but i am curious if you only feed 5v what the batteries are charging to?
Aug 28, Not a ton of power but if you still run this on batteries the resistor will unnecessarily waste battery energy, regardless of how small. Anybody with input on how to reverse the polarity on the N power jack? Last edited by SCF; Dec 08, at That vatasheet give me what i need to know.
I ended up getting this fixed up the right way. I picked up an MCX last week and thought it was silly to keep expending batteries so I reverse engineered the charger, came up with a solution then looked to see what others had done. When I put a battery in the charger it seems to work daatasheet fine.

Neither time is the battery so much as warm to the touch. Mar 22, Used a meter to do it right. I should analyze the circuit in the charger to see how they have it connected because this would also lead to inherent problems when using rechargeable batteries Mar 13, I found the issue.
A resistor changes the current flow and also expends heat or power. Aug 11,datashwet
