demonjester Posted January 18, 2013 Share Posted January 18, 2013 I am currently working/experimenting with these tp link wr703n (soon gonna buy alfa router and flash pineapple, and tp link tl-wr720n pocket router) and I came across this idea, what if you're able to do the internal usb hub mod same as the tp link wr703n. I am sure someone has done this already? If so, I figured it would be a popular mod. https://forum.openwrt.org/viewtopic.php?id=34188 I am definitely going to try it when I get mine.

Sebkinne Posted January 18, 2013 Share Posted January 18, 2013 The power draw will be too high for 5V. Means you would have to supply it using mains power - hinders portability a little. Otherwise, sure this is possible! Quote Link to comment Share on other sites More sharing options...
RChadwick Posted January 18, 2013 Share Posted January 18, 2013 I've done this a while ago. I really haven't had time to test it out (Haven't powered up my Pineapple in months), so I don't know how well it works in practice, but devices are recognized in both ports without problems. I replaced the single USB port with a double-high USB port, and extended the hole in the case. The hard part was to work the hub around the light pipes for the LED's. I bought a cheap, small hub on Ebay, took it apart, and cut the PCB down to the bare minimum. Everything fits on the back of the double USB connector. For portable power, I grabbed a cheap DC-DC converter PCB from Ebay. Some are adjustable, and can easily convert 5V (Or even the 3.6V directly from a pack of salvaged Li-Ion cells) up to 8V. Something like this: http://www.ebay.com/itm/LM2577S-DC-DC-4-35V-Adjustable-Step-up-Power-Supply-Non-isolated-Boost-Module-3A-/121053536136 Of course, basic soldering skills are required.
