li-ion vs aa batteriesview story

http://forum.allaboutcircuits.com – Hello. I have an rc car that has a 4 as battery pack that's makes it 6 volts, I have some 3.7v li-ion cell phone batts. So 2 of those in a series would be 7.4v with a combined current of 1800mAh. If I regulated the voltage down to 6v would they perform better and longer than the 4 as batteries? (Embedded)

Traffic signal/7 segment displayview story

http://forum.allaboutcircuits.com – I know I am jumping in from no where but thought it would be helpful.The thing is that I am new to PIC 16F877A and have made this simple code on PROTON IDE which is abt controlling 2 traffic signals and running a counter at the same time. (Embedded)

mosfet not switchingview story

http://forum.allaboutcircuits.com – I have a project that is using a car battery for power and a 5 volt touch plate as the signal. When i connect to power and i turn it on ( touch the switch) it turns on but it does not turn off. I am not sure where to go from here. Is the resistor from gate to source the wrong value?

Efficiency of RFMD,s RF6886 HPAview story

http://forum.allaboutcircuits.com – Hello, We are using RF6886 power amplifier in our application. We tested RF6886 for our application. But we got very less efficiency. Current consumption was very high. The gain was also not constant. (Embedded)

12V bus transceiverview story

http://forum.allaboutcircuits.com – Hi, I need to design a circuit or find an IC that can switch several bus lines up to 12v. They also need to go to high impedance so that they do not interfere with the other devices on the bus. I have used a TI device before, which works great, but only goes up to 5v max. Ideally, it also needs to be ESD protected. Anyone got any ideas? Much appreciated (Embedded)

need help to understand fourier transfomview story

http://forum.allaboutcircuits.com – please anyone help me to understand what does it mean I have read this article but I am bit confused A Fourier transform take any function and convert it in to eqquivalent set of sin way If you plot the electrical signal going in to loudspeaker that's playing music you will say wave line where the wave are some time big and some time close together other time smaller other time further Appurt' (Embedded)

VLSI Switched capacitor not working as planendview story

http://forum.allaboutcircuits.com – Hi everyone! Im currently working on an analogue assignment where you take a square wave and convert it into a sine wave. So the method that is suggested and looks nice is to use a sallen-key low pass amplifier. Now I have it done....if the world was ideal. (Embedded)

Need help with a projectview story

http://forum.allaboutcircuits.com – I am new to this forum and also new to the field of electronics. I am a computer programmer by profession and hobby. I have a few ideas where I would like to get a microchip programmed and fabricated. I can explain this in detail if any one is interested in helping me create one. Can this be done on a small scale without having to pay big money.$$$$ Thank you for reading my post (Embedded)
