Have some questions about building a AOM-5024L-HD-R mono mic to connect to a USB sound card to capture low frequency sounds.
This is some info from the web:
1) A reviewer of a Ugreen USB sound card says: The microphone input is designed for a 3.5mm stereo mini phone plug. If you use a microphone with a mono plug, such as a Denon receiver calibration microphone, be sure to plug the microphone in only partially – if you plug it all the way in, it will NOT work. It should also be noted that the UGreen USB audio adapter will output stereo but the microphone input is mono only.
2) The mic input power for several USB sound cards can range from 2.43-4.59V and the nominal spec for the AOM is 3V.
3) The recommended soldering duration for each terminal should be 2 seconds and a metal fixture can be used to hold and act as a heatsink.
What are your thoughts on using lead-free solder and is extra rosin necessary?
Which sites do you recommend for parts like 3.5mm plug and bare wire?
Can you buy the AOM capsule with cables already soldered, or on a PCB?
Can you recommend a budget soldering iron/station, quality seems to be an issue when reading reviews? I remember soldering a small chip to a Playstation with a no-name iron, but the solder was probably lead based.
