What do you use for 3.3 v? - TheBuzzer - 09-07-2012 I am learning how to mod a docsis 3.0 modem, i already gotten usbjtagnt, lot of 1pin header wires, and the test clip. Now i am missing the 3.3v I am thinking of buying this board to be able to do the 3.3v http://www.dfrobot.com/index.php?route=product/product&product_id=488 Or is there a better solution? also does anyone know the pin layout to connect usbjtag to a testclip for arris 802g modem? RE: What do you use for 3.3 v? - drewmerc - 09-07-2012 i just use the vcc wire of a cut usb cord (5v but it is within tolerances so no worrys) RE: What do you use for 3.3 v? - TheBuzzer - 17-07-2012 mainly because i am trying to do solider free wiring. so i got a bunch of 1 pin wires that can connect to the spi clip and the usbjtag nt. also it should be able to connect to this breadbox. now i need to figure out the 802g wiring diagram to know what to connect to what pins. RE: What do you use for 3.3 v? - CableGuRu - 17-07-2012 if you want to make the 5v from a usb cable into 3.3v then you can put two 1N4148 diodes together on the 5v to bring it down to 3.3v. RE: What do you use for 3.3 v? - torro32 - 19-07-2012 solutions for noobs, the rest of us probably have adjustable power supply: 1. use 3.3V from the PC PSU. (orange wire). 2. use cell phone battery they are usually 3.7V, drain it a little till about 3.3V. 3. open your DVD player, the chances are 99.999% it has 3.3V stabilizer and some internal circuit running on 3.3V. Run + and - wires and that's it. 4. drop 5V usb power with two diodes or some resistors, one in parallel and one in series. hope that helps
