Learn it all

Malachai — Sat, 11 Oct 2025 16:13:13 GMT

Hello, it's nice to meet like minded people. I've forgotten more than I knew in the past due to a brain injury. Time to rebuild.

I have slight awareness in a lot of concepts. I have extensive history in mechanical sciences as a cnc programmer and heavy machinist of 25 years. I learned a lot about problem solving and solutions building but would love to engage with individuals who have the patience to help me learn about applied power systems, robotics, anduino, and more. I greatly look forward to learning/relearning basic concept and theory; untoward advanced robotics, automation, and building.

I would like to build autonomous drone applications for ground,water, and air. I am the out of the box problem solver guy that had issues putting brain to paper to project. In that regard, I would like to participate in problem solving groups, and learn what I can while engaging.

Unorthodox? Perhaps.... but we all work differently don't we?

Giveaway received from element14 as a winner for current sensing quiz

I was looking for such scope where I can connect it to a computer for testing my electronics circuit and make a content about that circuit. This scope gives me those possibility.

Above is a Usb cable for connecting the scope to the computer.

Scope probe for testing your circuit.

the above scope is a 25 Mhz scope. It is good for testing of DC to DC convertor, and audio electronics. I will probably be using this scope for making a lot of Audio related circuit and would be sharing on it on element14.

Experimenting with Op Amps: active full-wave rectifier

Jan Cumps — Fri, 12 May 2023 21:00:29 GMT

The Art Of Electronics features a set of practical op-amp circuits. They have several full-wave rectifiers. I'm trying the simplest one. You don't need fancy devices. A pair of 741s will do.

The circuit:

image source: my copy of the book. fair use.

Looking at the node where the arrow points to:

for positive values, the first op-amp is an inverting buffer.
for negative values, the op-amp output has a 0.6V dc bias, the right side of the feedback resistor will be at 0 V (ground).
hint: the 0.6 V output is generated by the op-amp to drive the inverting input to the same value as the + input (ground), effectively clamping the output to 1 diode drop above ground.

Looking at the second op-amp:

it is an op-amp with a summing node. Two signals at the inverting input are summed and inverted. The amplification factor is defined by the input resistor and the feedback resistor.
for the input signal, the amplification = -1 * R/R = -1 (the input resistance equals the feedback resistance, resulting in the -1 amplification factor, doubling and inverting the signal)
for the signal coming from op-amp 1, the amplification = -1 * R / (R/2) = -2 (the input resistance is half the feedback resistance, resulting in the -2 amplification factor)
it is an inverting amplifier for the input. Both positive and negative signals are amplified by -1.
for the signal coming from the first op-amp, it acts as a -2 amplifier.
for positive inputs, this results in Vin * -1 + Vin * -1 * -2 = -Vin + 2Vin = Vin -> result: Vin, positive Vin comes out as positive Vin (see comment)
for negative inputs, this results in Vin * -1 (making Vin positive) + Vin * 0 * -1 -> result -Vin: negative Vin comes out as positive Vin

Here is the result: The blue line is the output. Underneath it, you see the input. The output overlaps the input for the positive part. It inverses the negative part. No diode drop.

Thanks for the feedback. Some of this we won't be able to do anything about because it's how Verint operates, but we may be able to do something like a glossary. Scrolling down on /members-area/support/p/site-faq does have some of this information at least.
