 ### Notes
 This project could use a lot of work, mainly:
 1. We could integrate the NRF24L01+ into the PCB boards.
-2. Add the components of the Mico-LiPo into the main transmitter PCB Board.
-3. Translate the assembly code into Arduino code to allow the use of smaller micro controllers and possibly 2 way communication.

 ## Making the Receiver
 1. Populate the Receiver PCB with the appropriate parts (The essential resistors & capacitor can be either SMD or Through-Hole):<br/><p align="center"><img src="N64_Receiver/RXParts.png"><p>
-2. Connect the ISP pins for your desired programmer to the Receiver Board. Hopefully this refference image and the PCB silkscreen will be of some help.<br/><p align="center"><img src="N64_Receiver/N64_RX.png" alt="drawing" width="800"/><p>

 5. Cut the N64 plug from the controller, making sure you have some length to route & solder to, I usually keep amount 20cm of cable and cut as necessary.
 6. Check the fit of the plug to the printed box, some 3D printers make the opening too large or too small.
 7. Glue the Connector to the BOX.

+17. Attach a battery to the micro lipo and test the mod. Remember if you press the A button while powering the N64 controller with the mod, you will set the channel to A, while if you press B, you will set it to Channel B.
+18. If all works button up your device. I recommend routing the battery to the Left hand side of the controller, the custom board to the Right, and feeding the NRF24L01+ into the nook of the expantion slot.<br/><p align="center"><img src="Extra/Images/9.jpg" alt="drawing" width="500"/><p>

+## Warnings!!
+Make sure the polarity of the receiver pins is correct or you risk blowing the N64's power module, or worse, frying the N64 completely. In you connect the Batter pins or the N64 pins to the wrong wires you risk frying you N64 controller. I've tried this mod on reproduction N64 controllers, but it seems they allow some electrical noise that messes us the communication pathways and making it seem like you've pressed buttons you didn't actually press. If you mess with the power pins on the NRF24L01+ you risk breaking either your n64 or the controller, depending on which one was wrongfully connected. However, messing up the data pins of the NRF24L01+ breaks nothing. If the battery is too low, it will keep the LED light on, but might not send any control signals to the receiver.
