At first I thought you meant Muzo, but it's yet another one.
Here's a review of Muzo: https://youtu.be/MCW5HUkrr-o

At least the moles and gophers won't be in their walls.

Yep, but it retains some resistance to ground because the LED resistor stays in circuit to prevent overloading the output. Since the signal to turn on is taken from the next step up, it'll turn the lower one off, and as the voltage increases, the lower outputs stay active, continuing to shunt the LE...

Only thing I can find is via Digikey:

Go back to the "ok, new project time" thread ( https://forum.nutsvolts.com/viewtopic.php?f=45&t=17714 ) and look at the LM 324 circuit. Just use 1/2 of the shown circuit, but insert a NPN transistor and possibly a resistor as a switched path to ground, effectively grounding the input to the led. Her...

It's based on the old style Quasi-Complentary AB amps of old when high power PNP transistors were rare. Yes, I could use lovely modern units and not go that route, but, nostalgia, ya know. It all works out in the end.

I was just trying to figure out why it looked like that.

I think I see why I get that reading. Mostly they are used with a split power supply and a GND point between them. Thus, in this particular case, the negative transistor (PNP) never really has the chance to go more negative than the ground reference point.

Well, it's ten years later and I have a question about this and many other very similar circuits. Being that this type of circuit is class AB, wherein the B section is supposed to split the amplified signal in half, with each respective transistor amplifying their respective polarity of the wave for...

What's the TIMEOUT set to? It may need to be increased. Were there any updates that may have caused the problem? For all you know, it may be on your internet provider's end in that they may not be 100% compatible with your router. My Story: Way back when my kids were in school, we were not happy wit...

These boards are designed to basically be "plug and play" and should work right out of the box. Are you trying to use it in a manner that is not described in the included paperwork? Again, is there a schematic or at least a link to the board you have purchased? Just how are you going to use the boar...

I see you can use the old router just fine, so it's not necessarily the Internet connection. (That's another story that I think I told a long while back) Did you try to connect to the Amped router with other devices to rule out the main connected device? Can you connect to the Amped device without i...

That is not normal behavior. Even if you have an existing file, the popup would be the Overwrite/Replace question. Have there been updates or have you had to log-in just before this started? Is it possible that Word was installed as Administrator only and you are not on the Administrator account? Is...

Funny you should bring this up. In the transfer of files from the old laptop to get info for my oldest to get into design, I grabbed all my old bookmarks and there were quite a few related to CAD / CAM stuff that were for some sort of CNC or vinyl cutting, etc. Back in the day, I was able to write H...

Being as you are using a MC (the Raspberry Pi Zero), you can either include a battery voltage monitor routine that automatically puts the MC into low power / sleep mode, or a button push that would do the same. Once that is done, you can use a smaller capacitor since the drain will be greatly reduce...

Here I go again, another wierd discrete component audio query. Still in the audio reproduction mode (it's my main electronic interest ;) ) and this time I'm trying to understand how the "volume control" on the PSAudio amps work. Paul (the P in PSAudio) says that they use gain blocks for their volume...

Well, I would comment, but I don't have a CNC machine. Always wanted one...
