    Soldering a wire onto a PCB that is already soldered?

    i can't do that at the moment.. im not at my dads house haha i was wondering maybe it possible to use jumper probes as a wire instead? it might be a little difficult.

    Soldering a wire onto a PCB that is already soldered?

    there are none. this pcb was made by my dads company. he bought it home so im playing around with it.

    Soldering a wire onto a PCB that is already soldered?

    are there any tips on doing so? the pins of the op amps are pretty close to each other. also its my first time soldering so im not sure how it will go.. lol

    Soldering a wire onto a PCB that is already soldered?

    Hey guys so I have a PCB board with an op-amp pins soldered onto it. I want to be able to connect wires onto the pins of the op-amp. The pins are all soldered into the board already. Do I simply solder the wire onto the pin? How can I do this carefully without spilling any solder onto the other...

    How does a DMM measure voltage, current, and resistance exactly?

    I want to make a software program which emulates a DMM, but have no clue as to how the DMM actually measures these 3. I know Ohm's Law is used. For measuring voltage I was wondering if the DMM probes have a huge input resistance? For current I was wondering if the DMM probes then change to a...

    Making a harmonizer problem on FPGA

    So I've found the bin and output a 16-bit frequency ranging from 0 to 48000 based on the formula f=bin number * bin size where bin size= samplerate/samplenumber I was wondering how can I input this frequency into my IFFT? My IFFT core takes in a real and imaginary input.

    Making a harmonizer problem on FPGA

    My FFT core does not output a bin index. It stores it into memory. I was wondering how can I read it from that memory module?

    Making a harmonizer problem on FPGA

    I understand the bins and how the binsize is the SampleRate/Samplesize. I was wondering how can I use these bins to find the frequency? I'm confused to what you just stated. I was wondering if I can somehow find the bin with the maximum magnitude, and then multiply that bin number by the bin...

    Making a harmonizer problem on FPGA

    Hi I have a problem making a harmonizer. So I have an 256 sample FFT which outputs a real and imaginary magnitude output of the frequency at each bin. I was wondering how can I compute the frequency from the magnitude in order to multiply the frequency so I can get a pitch shift? I'm not sure...
