Remove at battery terminal. Jan 14, Help with qualcomm charger modification!
Is this the battery you are looking for? When I put a battery in the charger it seems to work just fine. That should datashfet me what i need to know. Two diodes in series was my approach. Jan 13, Dec 08, Aug 24, Page 9 of 10 First. Dqtasheet diode approach does not change the current profile as they only drop voltage, not limit or change the current.
Jan 15, My best guess at this point is my use of the wrong solder. Mar 22, RF Eng Registered User. Has anyone checked what the charged voltage of their batteries are after charging through the usb? I just noticed on the datasheet for the AA transistor they state the collector-emitter saturation voltage is 2v so using 6v of alkaline Datasneet batteries you should get a charge voltage of 4v but i am curious if you only feed 5v what the batteries are charging to?
Scratchbuilt Indoor and Micro Models. Aug 11, I have a cellphone wall charger with an output of just over 5V Quote: Jan 04, Cathode stripe goes toward the LED. I remove the AAs and try again with another.
The SOT is a mystery to me.
Selling AA-Y, AEC, AY with AA-Y, AEC, AY Datasheet PDF of these parts.
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.
Originally Posted by dafasheet I thought you guys might be interested in a different type of mod I posted. I should analyze datashert circuit in the charger to see how they have it connected because this would also lead to inherent problems when using rechargeable batteries On the second charge cycle this degrades further to ma and so on. Then the light stays lit after I remove the dataasheet.
Return to Coaxial Helicopters. Do not exceed 4. Not a ton of power but if you still run this on batteries the resistor will unnecessarily waste battery energy, regardless of how small. Keep in mind ma is the absolute highest and that is only one cycle on brand new AA cells.

Aug 28, a28a, Also, when I use the wall wart, I get nothing. Can you do this Mod AND modify it to a wall charger as well? May have fried something on the board.
I found several other mods that prevent you from being able to put AA batteries in, or they require you a9228a leave a single AA battery to power the LED. Diode Mod and Battery Profile 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.
Whether you put a resistor in series or get the right voltage wall supply set your voltage at 4.
