    A/V switching circuit

    Hey guys, just thought I'd spitball a question.

    I'm considering building a "game console shrine" with as many consoles as I can find in a showcase, and having them all playable.

    I'm looking to build a circuit that can switch the A/V source to each console, preferablly with a push button at each console. Similar to the speaker selection display at Bestbuy/frys/radio shack.

    I saw a crude design at engadget, but I've been reading that the IC's used in its design are not really for that purpose. Also, what about the consoles that use YPbPr or HDMI?

    My hifi reciever has some inputs, true, but I'm expecting about 12 consoles at least, and I would love for this to be as idiot proof as possible.

    Has anyone messed with a project like this?

          Desoldering gun station modified to use a 18 volt @ 20 amp switching power supply
          by sam_sam_sam
          I have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump

          One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy...

          Fixing the Charge Circuit of the Batteries of the DC Motor
          by Astonished
          Hi friends of electronics

          What you see in the video and pictures attached is the circuit for charging the batteries of a DC motor.

          The problem is that this circuit cannot charge the batteries (3 1800mAH NiMH batteries) any more. When the circuit was OK, its green LEDs lit up one at a time to show that the batteries have charged more. But now that the circuit is flawed, LEDs light up as you see in the video and at the same time successive beeps are heard.

          Please help me fix this circuit.

          Lenovo L490 Ram voltage circuit malfunction
          by rddube
          Hello friends,

          Looking for some guidance here. The RAM voltage circuit on this motherboard keeps burning out PU301 which is a RT8231AGQW. Copy of the board with the burnt chip attached with some voltage measurements and copy of the schematics also included.

          I think I've checked almost every component in the circuit, but when I change the RT8231, the laptop starts I have 1.2V on the inductor for about 10 seconds and then the RT8231 goes south and no more voltage on the inductor. All other voltages on the laptop are good, this is the only one conking out for a reason I...

          Short Circuit tester
          by Tarot Superstars
          Hello.
          I have seen a short circuit tester made with 3 * 9V batteries, a voltage limiter component and a resistor connected to the probes of a multimeter.
          The theory is that the meter becomes sensitive enough to read very low resistances and the lowest resistance to ground on a circuit is likely to be a short circuit in that area.

          Nintendo Switch lite shuts down after nintendo log and replaced M96T36o
          by fab13
          Hello everyone

          After checking the defective USB-C port and close to a short circuit on the M96T36 chip (8ohm) I have changed both components.
          I specify that there is no other short circuit or heating component(Vu thermal camera)

          First, the problem arises: Error 2101-0001 after the start-up screen ("Nintendo" logo), poor soldering.

          Secondly, I install a new M96T36 and the problem I have is a brief display of the "Nintendo" logo (no short circuit, no sure charge chip, no sure charge port, no sure charge management chip percentage)....
