What really happened to my Arduino Uno R3?

My Arduino  Uno R3 was working properly, but I connected it to a power supply board along with relays and GSM modem and some voltage fluctuations and blinking occurred. I immediately disconnected everything from it and connected Arduino to my PC. But I was not able to upload any programs to it. avrdude: stk500_recv(): programmer is not responding I was getting this error report. I disconnected every connections from it, but still I was not able to upload programs to it. When connected to PC the 'ON' and 'L' LEDs are glowing steadily. No blinking occurs to 'L' LED even when the reset button is pressed. Also the micro-controller chip is getting overheated(By a little more than usual). There is no problem with my USB drivers because I am sure that it was working fine on Windows and Linux. Can you please tell me what the problem is and how to fix it? -Thanks

can i find the resistance of a resistor if its burnt?

In one of my helicopter controllers, there is a burnt resistor. it burned when my brother tried to charge his more expensive helicopter with it. i looked at it and all i know is that theres a yellow stripe and a gold one, but thats all thats visible since the middle two stripes have been burnt off. will it still have the same original resistance when tested with a multimeter? how can i find the resistance of it so i can replace it? i havent got another one of these controllers to compare it with. it has a very similar controller shape as the air hogs havoc helicopter, except this helicopter cost only $20. because the resistor is burnt out the controller cant charge the helicopter, and i dont know the voltage that the copter takes in, and the copter doesnt have any battery protection circuits as far as i know, so i cant charge it. can someone help me figure this out?

Home stereo stopped working possibly has burnt out voltage regulator? Answered

Greetings, My Altec Lansing home stereo stopped giving out sound.  There is still fuzz audible from the speakers, but there is no musical sound whatsoever coming through the speakers.  It is a simple stereo but with good sound.  It has one input Jack which has always been loose and finicky; as long as I carefully plug into the Jack and make sure it is a good connection, the stereo has worked fine.  One day however it suddenly stopped giving any musical sound.  I decided to open up the stereo and look inside.  First I tried bypassing the input Jack since I suspected that was the problem.  Bypassing the input jack however made no difference, there was still zero audio signal coming out of the speakers (still only the buzz).  I then looked around on the motherboard to check for any oddities. Everything looked normal except for one Voltage Regulator.  It is a L7809CV.  It has three prongs and a built in heatsink. The point at which it connects to the motherboard is slightly burnt looking as it is discoloured. In the upclose picture you can see two voltage regulators, the one on the left is the one which appears burnt. I was thinking this is likely the culprit.  Would anyone on the forum have any feedback to offer.  Do you think this is the problem, and would replacing the voltage Regulator likely fix the amp?

DTH satellite receiver problem

I have a DTH satellite receiver which has a burnt SMPS power supply (image attached). I replaced the burnt components but again when powered with 220V ac supply to test the output voltages the same components burnt again within a few seconds. I could not figure out what is the actual faulty part. If anyone has any suggestion please feel free to answer. My second problem is the satellite receiver board (image attached) has 6 pins for power connection but I could not figure out what voltage is to be applied to which pin. So I was unable to use a separate power supply for the receiver board. The part number can be seen from the image itself. Please look at the receiver board and help me if anyone has any idea about this board. I tried searching in google with the part number but could not find the same board. Please help me.

LED Series Resistor

I just finished soldering a board to flash an IR LED using a 555 timer, and attached it to 9V PP3 battery, and the LED burnt out.The LED was rated at 1.7V 100mA and I was using a 100ohm series resistor. By my reckoning I should have only needed a 73ohm resistor, (9V - 1.7V) / 0.1A = 73ohms, so 100ohm was more than enough.Any ideas?

Resistor Value for LED series?

I am new to electronics, just started it as a hobby, and tried my hands to make a LED Series. As I am not aware of the exact calculations to figure out the resistor value, I am facing problems - resistor is getting burnt. I am just seeing a led series bought from the market and trying to make another one based on its circuit & design. The overall scheme & design of the circuit was:  - I made a series of total 44 white led lights. - Added a bridge rectifier first (4 diodes joined in a systematic way), - then came three led's with 1K Ohms resistors each - then followed 38 plain led's, - finally three leds again with 1K resistors each. The last three resistors got burnt after 10 odd minutes. Obviously the resistor value is not right. What should be the general thumb rule to figure it out. I wish to make few smaller series of 12, 24 & 36 LED's, how many resistors do I add in each? Will be thankful for some guidance.
