    Modified sinewave to pretty good sinewave?

    It is indeed a sad state of affairs. I think it was Switzerland that mandated the hours that one could charge their EVs and the electric cars are to be driven only in the case of extreme emergencies. Hopefully our paper currency will maintain a value greater than that of kindling and wall...

    Modified sinewave to pretty good sinewave?

    The latest info I just heard about the overheating problem that seems to accompany the modified sinewave (modified square wave?) inverters is that when trying to "regulate" the ac voltage with a capacitor, this is when overheating is going to be quite obvious. Devices like a motor with a run...

    Modified sinewave to pretty good sinewave?

    Here is an update on my theory as it relates to my earlier suspicion that because of the long duration of the power wave supplied to a transformer primary winding, sitting at a constant voltage (modified sinewave), would induce a greater rise in temperature of the winding than normally occurs...

    Looking for suggested dynamic microphone power level

    CAN YOU HEAR ME NOW? I am fortunate that the conclusion that it could become very difficult to produce a quality recording with sub- quality devices, seeped through my mental firewall. Being rather stubborn and persevering, I have been known to whip a dead horse fleshless.

    Looking for suggested dynamic microphone power level

    I have done a couple experiments using my acoustic guitar as the sound source. As normal I would record live guitar music with Voice Recorder. Then move recording to Windows Media Player. There I could use graphic equalizer to enhance or level out the intensity of multiple freq ranges. To make a...

    Guido is a host for live webinars (?).for a Dr. Duino. He deals with arduino devices I think. Personally, I do not know.

    Looking for suggested dynamic microphone power level

    I share the same sentiment mostly. My desire to record and/or amplify the sound of my acoustic guitar is the foundation of my audio quest. I tried the type of add-on pickup that holds on to the sound hole. I tried a pickup that is held to the guitar with a spring clip. Both styles were far from...

    Looking for suggested dynamic microphone power level

    I may have wiped out those freqs with equalizer. For whatever reason, if I increase intensity of freq bars 1 kHz or 2 kHz they generally bring along a hiss or static. I'm guessing computer fan motor, frig, I am uncertain. I am intentionally trying to emphasize the bass sounds. Led Zepellin Bring...

    A shocking thot

    I did have a salvage computer with translucent panels. Thot that a bit silly but I'm not the trend setter. I think I've seen translucent phones. Maybe dreampt that.

    Looking for suggested dynamic microphone power level

    I'm sending a link to video (audio actually) made using my dollar tree mic. Bassline was recorded first. During its playback, lead was added. Duo was played back on Windows Media Player where equalizer and playback speed apps, among others, could be used. Then that playback was rerecorded to...

    cameras

    Since we are on camera topic, I still desire to have a device that will readily recognize and display thermal regions. I was at Seeds and they do sell thermal imaging cameras. Is there that much difference in the photo sensor chip (plate?) that a minor modification could not take a visible light...

    A shocking thot

    I had recently lashed up an extra power supply to my computer to replace its malfunctioning one. I left the room then returned and gasped as I perceived the new PS to be glowing hot. I was utterly terrified for one second before reasoning told me there was no smoke and the supply was running...

    Looking for suggested dynamic microphone power level

    The dollar mic I use does require that the sound source be somewhat near it. My current main use for a mic is to record acoustic guitar sounds. If I point the mic at the guitar and guitar is 2 to 5 feet from the mic, the recorded sound is surprisingly good. I am sure you are correct about a wide...

    Looking for suggested dynamic microphone power level

    A couple articles implied that the Shure SM58 was an industry work horse. On Amazon the SM58 if referred to as a dynamic mic and I suppose it is, utilizing a movable coil in respect to a permanent magnet. For now and until a more polished sound is required for my music recordings of my practice...

    Looking for suggested dynamic microphone power level

    The following attachment (or similar info) is what has been influencing my conclusions and train of thot. It was my intention to use a 3.6 VDC supply virtually where the cross-section diagram shows "battery." The 3.6 V can be produced by a secondary CV circuit using amp supply of 12 VDC or my...

    Looking for suggested dynamic microphone power level

    Seriously, if I were to perform in public, I would likely spend the 10 - 30 dollar price of a cheapo condenser mic on Amazon. Mounting hardware and a semi-ruggid enclosure would be included so as I would not have to fabricate pieces.

    Looking for suggested dynamic microphone power level

    Am I correct in my assumption that other earlier generation condenser mics of simpler construction are still manufactured these days? I'll try to attach a photo of the headset with which I am experimenting. This mic reads approx 800 ohms across its 1/8" plug contact areas. What I am seeing as a...

    Looking for suggested dynamic microphone power level

    Myself, being mostly ignorant of anything microphonish, from lack of experience, referred to my Dollar Store headset microphone as a dynamic mic. Silly me. I did that based on the SWAG that since its output was negligible in an unpowered mode it was therefore "static" and required an active...

    Looking for suggested dynamic microphone power level

    I use a dollar twenty five cent headset microphone for recording purposes on my computer. I have made the assumption that an auxiliary source of current is needed to travel thru the mic to supply the varying converted audio waves to analog signal driving the amplifier inputs or maybe the power...

    What am I not seeing here?

    Interesting. Thank you.
