So I want to add some LEDs now to my Xbox. I don't have an understanding standing yet of electrical currents and voltages and resistors it'll be something I pick up as I understand but if someome could point me in the right direction or give me we ideas on the things I might need?


I'm curious to how many LEDs I could run or how to figure that out.

Hello, it exists some 5volts leds like the one I use on dreamcast led mod, but very often you will find leds that works between 2.0 and 2.8 volts.

So, for example, if you want to add leds to pad connector (inside), it is easier to find 5V leds as joypad connector are USB-Like 5V.

Else, using a multimeter, you can find some caps pads in front of the motherboard that deliver 2.5 volts.

Don't forget that U (Voltage) = R (resistance  ohm) * I ( current)

Very often led max amp is around 20 mA, but 15 mA is enough.

So If you know U and I, you can calculate the resistor value, not to burned your led.

U / I (divided by ) = R

Example: 5V divided by 0.015A = 333 ohm

      Anyone got a good guide on installing LEDs or a cathode tube into an original Xbox? I guess i need to know some good 12v and ground points

      Selling this beauty. Only 4 consoles were ever made. I’m looking for offers really. Anything over 1000£ + would be considered. Will ship anywhere in the world, But you pay for that cost. Is usualy 69 £ tracked. Have a great one!

      Need a checkup on building a EEPROM reader from a person with a background on electronics.  Can I use two leds in series instead of a 5.1V zener diode rated at 1W for a EEPROM xbox original reader?  Can a 3.0V coin battery or 4X1.2V AA batteries @ 4.8V be used as a external powersupply directly?  Would 4.8V have too high of mAh or current for the EEPROM chip?  I plan to use a serial to RJ45 with a connector to ethernet as a cable.  I am using a bread board to create the circuit.  I plan to use the materials I already have.
