(Left to Right)
- Something to hold the tiny pieces together while you solder
- Wire snips
- Soldering Iron
(Left to Right)
- Male USB Connector
- Female USB Connector
- One 33K Resistor
- One 10k Resistor
I ripped my USB connectors out of a USB extension cable.
Cleaned them up a bit.
attention to the orientation of the USB connectors to each other and which pins are GND and +5V. You could damage your Tab if you end up switching GND and +5V by mistake.
You could also end up with a non-working adapter if you flip the resister locations.
Place the resisters side by side and solder their leads together on one side. Then solder them to the D pins of the female USB connector. Make sure the 10K resistor is on the D pin closest to GND!
Keep the trimmed resistor leads for use in Step 4.
Angle the non-soldered ends of the two resistors away from each other so they line up with the GND and +5V pins of the male USB connector. Make sure the USB connectors are aligned so their respective GND and +5V pins are on the same sides!
Now clip the resistor leads that were bent back towards the female USB connector and solder them to its GND and +5V pins. Double check that the USB connectors are aligned so their respective GND and +5V pins are on the same sides! BE PARANOID.
Use the trimmed resistor lead you kept from Step 1 to solder the chassis of the USB connectors together.
Take 5 minutes to admire your handiwork.
STEP 6 (IMPORTANT - DO NOT SKIP)
Take 10 minutes to check the following
(1) USB connectors are lined up correctly. GND & +5V are not crossed.
(2) 10K resistor comes from GND and 33K resistor comes from +5V. Adapter won't work otherwise.
(3) There are not short circuits / crossed / touching wires. Many bad things could happen.
STEP 7 (TEST)
Without adapter. @$%#!
With adapter. Success!
NEVER CONNECT YOUR TAB TO A USB PORT THAT SUPPLIES MORE THAN 2A - BE PARANOID.
Reinforcing and packaging (paperclips & electrical tape).
