Yup yup
:bigsmile:
Thanks for the quick response.
Can this be ordered as a complete item, build kit, orā¦just a board, and we buy the parts separately from digikey/mouser/ebay? Will a housing/cover be part of the get-up, or is the board just left exposed?
I am amazed at the talent an ingenuity of BLF members. Nicely done, WH!
So far just board, I put BOM on OSHPark page and here for DIYers, but I am sure RMM might pick em up and sell em, I did it creative commons license no commercial, but put BLF on it because itās āoursā
No cover as of yet. Need to get one for meaurements then try to figure out printable case
Very interesting, i may want a few of these, especially if RMM starts selling them
Clear 18650 shrink wrap from FT works great.
Oh yeah, al my TP4056 charger modules get that treatment now 
WarHawk, you might want to think about selling a couple!
What about a JB Weld case, of course it would not show the pretty parts so it wouldnāt be perfectā¦
So do you have to flash the pertinent data to that mcu? Iām not sure Iām understanding how itās āAutomaticā unless the various codes are put in there.
Like the idea, slow on figuring out just how it works. lol
Get Richard to sell em and Iāll just pick up a few, donāt have to know how to build it just have to know how to plug it inā¦ :bigsmile:
Go look at data sheet, itās a resistance/volts signature on the data pins, there is nothing to flash, the IC does it all
Rather than being programmable such as attiny13 or other mcu, chips like this USB charging controller are hardwired at manufacture.
Warhark, remember data sheets are klingon if one doesnāt normally deal with them. :davie:
Ah, sorry my nerd was showing again: p
They are klingon to me too when they get to The mathsā¦ my brain catches on fire
Itās that thing in your earlobeā¦causes static electricity and ignites anything filled with combustible vapor.
Itās my recharge port 
Then whatās that cable coming out of your shorts?
Gotta have a ground 
You stood still near OL to long. Something like this was going to happen eventually. Looks like he has perfected the application perfectly.
Maybe this is related to the ideas in this thread. I just noticed that my iPad will not charge at the 2A rate when a Charger Doctor is inserted in itās path. Charges at a maximum of 1A. Would there be an easy mod for this or a whole new design?
I have ordered a couple of other āCharger Doctorā type devices to see if they will allow a 2A pass thru.
If the charge doctor passes data thru it, then the iPad is charging from the signature coming from the device itās plugged in, if not the charge doctor might have the data pins shortedā¦that is the one signature that should charge at a max of 1A on most devices but wonāt ever charge more than that.
You can actually take a regular ādataā USB cable, open it up, then short the D+ and D- wires (the green and white wires inside the cable) going to the connector that plugs into the devices needing charging (usually the USB micro male plug) it will charge at up to 1A and NOT ever pass data [It becomes a dedicated charging cable]
My module I made, and the IC on it will send the iPad signature back (it has 6 different charge signatures it can send out) to the device and as long as the charging port itās plugged into can deliver 2A or more, the device will charge at that (with losses thru the cables of course) [the chip autoranges and will change because it senses the input voltage, if it sags because the charging device pulls to much, it will change to a little slower rate until the input voltage comes back up to within tolerances of the approx 5vdc charge level]
Probably because the voltage it to low, i.e. the "Charge Doctor" has to high internal resistance compare to the voltage from your charger.
This is something I test in my reviews of usb meters.
