    adding power voltage to microphone

    I have a computer mic rated at 1.0 to 10 VDC. I want to use it in an RCA application. I was hoping for some suggestion in addition to my plan to stick a 9 V battery (alkaline) in the positive path and a loop if I need the audio signal to remain constant. DONT LAUGH I AM ADAMANT.

      See http://www.epanorama.net/links/pc_so...ml#interfacing for the plug wiring. 0V is the Common (-ve or GND) terminal.
      Since you mentioned that the microphone runs from 1 to 10V, a 9V battery can be connected directly to it (with a switch to save the battery when you're not using it).
      Battery -ve to GND (3 - Shield)
      Battery +ve to Ring (2) via a switch
      RCA shield to GND (3 - Shield)
      RCA centre conductor to Tip (1)
      My first choice in quality Japanese electrolytics is Nippon Chemi-Con, which has been in business since 1931... the quality of electronics is dependent on the quality of the electrolytics.

              LG 55LM6200-TA country group/Area option
              by notallbad
              This is a 2012 LG TV so aware full functionality of the smart functions/apps will be limited however currently unable to get the LG Smart Store.

              Youtube, Netflix and LG Smart store icons briefly appear in the apps list but then automatically disappear after doing 'Initialisation of Premium' via the standard menu, I'm guessing this is due to the Country/Area group its set to is wrong for the UK.

              Unable to change the country group, Area option can be changed which alters the country group but none make any difference. So believe its the country group that needs changing....

              Gigabyte Z490 Gaming X Motherboard No VCORE Voltage
              by Fernon@Repair
              i have Gigabyte Z490 Gaming X Motherboard .it has a power on no display fault .. no vcore voltage and debug led stuck CPU LED .

              VCCIO voltage ok
              VCCSA Voltage OK
              VCCPLL Voltage OK
              Ram Voltage ok
              RamVTT OK
              VPP 2.5 OK

              But No Core Voltage

              and i want to this vrm ic datasheet or pinout (ISL69269)
              anyone have this ic pinout voltages?...

              Panasonic TH-L42D25A checking the PSU output voltage
              by electron_jj
              Hi Everyone, I am new to this forum. I have a Panasonic LED TV which doesnt turn on and is blinking 4 times repeatedly when I turn on the switch. The TV does not respond to the remote control so I had to turn on using the physical switch on the side of the TV. When I turn on the switch the 4 x blinking starts and repeat itself until I turn off the TV. There is a black screen. I turned off the light in the room to check the panel and I think there is no backlight as far as I can tell.

              I have been inspecting and testing the capacitors and diodes in the power supply board to try to...

              Trip light 2400 watt line conditioner bought used issue with low voltage oscillation going on between relays
              by sam_sam_sam
              I found two capacitors on the board and one of the leads on one capacitor had bad soldering joint and the other joint connections not much better and there were several soldering joints that way to much flux around the joint redid several of them

              The capacitors were a non brand that I did not recognize they got replaced and now it does not oscillating between relay but what concerns me a little bit is when the voltage is a little bit low the output voltage is around 130 volts and then drops down to 115 volts this happens around 105 to 108 volts if remember correctly

              Now...

              3+1 Voltage Regulator for IMVP-7/VR12 CPUs

              Compliant with IMVP-7/VR12, the ISL95831 provides a complete solution for microprocessor and graphic processor
              core power supply. It provides two Voltage Regulators (VRs) with three integrated gate drivers. The first VR can be
              configured as 3-, 2- or 1-phase VR while the second output is 1- phase VR, providing maximum flexibility. The two VRs share the
              serial control bus to communicate with the CPU and achieve lower cost and smaller board area compared with the two chip approach.
              Based on Intersil's Robust Ripple Regulator...
