Xeno Fusion
....this page is under destruction
Main
concept: use a xenogc modchip in tandem with wiikey fusion drive replacement
theory: use the atmega 8 on the xenogc modchip to trigger a response required for the WKF to initialize iso loading.
proof of concept: haha, no proof to show yet, but initial testing promises good results
Technical Data
The foundation for Xeno Fusion is based upon basic LED connectivity.
The diagram in figure 1 shows an LED connected to an Atmega8 (XenoGC) at pin PD5 and GND. Current flows from the anode to the cathode and a resistor is used for current limiting protection. Atmega provides up to 40mA output per pin.
fig. 1
Atmega8L (XenoGC) operates at 3.3v.
If an LED is rated at 2.0v forward voltage with up to 20mA forward current, then a current-limiting resistor value of 220ohms will provide 5.9mA of operational current which is under the 20mA of forward current allowing safe operation of the LED. Also the current-limiting resistor creates a 1.3v voltage drop.
current = (( supply voltage - forward voltage ) / resistor value ) * 1000
current = (( 3.3v - 2v ) / 220 ohm) * 1000
current = (( 1.3v ) / 220ohm) * 1000
current = (( 0.0059 ) * 1000
current = 5.9 mA
voltage drop = resistance * current
voltage drop = 220ohm * 5.9 mA
voltage drop = ~ 1.3v

Glossary
Confusing terms easily explained | |
---|---|
Reverse Voltage | maximum voltage that can be applied before it blows up |
Forward Voltage | minimum voltage required to operate. (basically, it is safe to apply any voltage amount between "forward" and "reverse" ) |
Maximum (or Continuous) Forward Current |
maximum current that can be continuously applied to a device before it burns up |
Operational Current | any amount of current provided to a device which allows save operation (see Forward Current) |
Current-Limiting Resistor | a resistor used to protect a device from receiving too much current (see Forward Current) |
Max Peak Forward Current | maximum current that can be applied during a brief current spike. typically ignore this value and rely on the forward current the device can safely handle to determine the current limiting resistor value. |
Voltage Drop | the voltage difference from the power source subtracted by the forward voltage equals the voltage used by the current limiting resistor. |
Transistor | used to amplify and switch electronic signals and electrical power. (two types of bipolar transistors: NPN or PNP) |
Relay | electromechanical or solid state device used to provide a normally open or normally closed output when energized or de-energized |
Diode | device which allows current to pass in one direction and blocks current in the opposite direction |
Photodiode | device capable of converting light into either current or voltage (a solar cell is a photodiode) |
Infrared LED | LED which outputs light in the infrared spectrum (see photodiode) |
ADC | Analog to Digital Converter which can be used to measure voltage |
