AI Thread Summary
Building a quadcopter from scratch involves creating all electronic components, including a 2.4 GHz FM transmitter and receiver, rather than using Arduino boards. The ISM band is recommended for this project, as it is relatively open and less prone to interference from common devices like microwaves and WiFi. Various manufacturers like Texas Instruments and Analog Devices provide integrated circuits suitable for the 2.4 GHz band, which can be interfaced with microcontrollers. The Jennic 5139 is suggested as a viable option, with programming available in C and free software resources. Access to a spectrum analyzer is also beneficial for ensuring compliance with frequency regulations.

I am planning to build a quadcopter from the scratch. I tried to do some research online, and am not happy with what I found. Everyone used Aurdino boards, and just connected the parts together. eg. http://aeroquad.com/

I want to build all electronic components myself like wireless FM tranmitter and receiver, but I cannot find a good enough source detailing all the requirements.

Any help is appreciated.

Sounds like a fun project. Do you have access to a spectrum analyzer that covers the frequency band that you want to use for the remote control? Are you going to use the traditional RC frequencies? I'm not sure offhand -- what is the allowed power level to the antenna for the RC frequencies?
 
I want to build a 2.4 GHz FM transmitter and receiver. ( One of the allowed bands by FCC). I still haven't zeroed on the transmitter/receiver design though. Any suggestions?

That ISM band is one of the easier ones to build to. As long as there are no microwave ovens or WiFi routers/laptops nearby, it's a pretty open band.

Several manufacturers make ICs for the ISM band. I think TI, Analog Devices, and Cypress offer ICs and modules. You could google 2.4GHz transceiver modules, to see what manufacturers make them. You would typically interface to the transceiver modules over SPI or similar serial interface, from your uC.
 
Try the Jennic 5139.

You program it in C and the software is free.

You want to get the development kit and that's a few hundred dollars though.
 

Thread 'How might electronics be different if AC voltage was 72V at 45 Hz?'

Hey guys. I have a question related to electricity and alternating current. Say an alien fictional society developed electricity, and settled on a standard like 73V AC current at 46 Hz. How would appliances be designed, and what impact would the lower frequency and voltage have on transformers, wiring, TVs, computers, LEDs, motors, and heating, assuming the laws of physics and technology are the same as on Earth?

Thread 'What happens if shielded cable has a short to the shield?'

While I was rolling out a shielded cable, a though came to my mind - what happens to the current flow in the cable if there came a short between the wire and the shield in both ends of the cable? For simplicity, lets assume a 1-wire copper wire wrapped in an aluminum shield. The wire and the shield has the same cross section area. There are insulating material between them, and in both ends there is a short between them. My first thought, the total resistance of the cable would be reduced...

Thread 'Why does the amperage go real high if there is a low voltage short?'

I used to be an HVAC technician. One time I had a service call in which there was no power to the thermostat. The thermostat did not have power because the fuse in the air handler was blown. The fuse in the air handler was blown because there was a low voltage short. The rubber coating on one of the thermostat wires was chewed off by a rodent. The exposed metal in the thermostat wire was touching the metal cabinet of the air handler. This was a low voltage short. This low voltage...
