    How can I use an on-grid solar inverter in an off-grid setup using a pure sine wave inverter as a simulated grid?

    Time flies, whether I am having fun or not. [hijacking the thread] Most of my attention the past couple of years has been focused on bouncing laser-emitted light off the surface of the Moon, and detecting the reflection here on Earth for communications purposes. I call this Optical EME...

    I need help with OnStep.

    You might want to head over to the OnStep forum for this: https://onstep.groups.io I need to build a remote-controlled (Bluetooth) equatorial mount for my optical-eme experiments, so I am interested in your project. For purpose of discussion, optical means visible laser light and EME means...

    How can I use an on-grid solar inverter in an off-grid setup using a pure sine wave inverter as a simulated grid?

    I have been pondering this question for quite some time now. Our grid-tied solar system is directly connected to our 200A distribution panel through a disconnect switch. That switch can be used by our electric utility, Florida Power & Light (FPL), to disconnect, and lock out, the solar array...

    IC Insertion tool

    If you can find them, a pair of "duck-bill" pliers works well on smaller DIP devices: a whole line of pins can be bent straight simultaneously.

    Bench power supply upgrade

    I got involved with Arduino a few years ago when I had a Bluetooth project. The project didn't go anywhere, but I still have the Arduino and the Bluetooth boards that plug into the Ardino board. I might revive that part of the project as part of a home automation project that takes advantage of...

    IC Insertion tool

    I don't know which Amazon product you purchased and had to return, but this insertion tool by Jonard, their part number MOS-2428, is listed there. It is supposed to work for 20 to 28 pin dual inline packages (DIPs). You might also want to visit this Jonard website where more insertion tools are...

    IC Insertion tool

    I thought the 21st century outlawed through-hole components in favor of itsy bitsy surface-mount components? You know, the kind that if you sneeze before re-flow soldering them to a circuit you never find them again...

    Bench power supply upgrade

    It's almost winter again. Are you still on this forum? How goes your power supply project?

    Artificial Intelligence---What is the Hardware Behind it?

    That may be the crux of your problem: expecting gifts.

    Artificial Intelligence---What is the Hardware Behind it?

    Wow, @Omega Supreme! And I thought I knew how to hijack a thread... Now, let's get down to the nitty gritty: ALL intelligence is ARTIFICIAL. I am going to use myself as an example, but I am sure you can relate. I was born around noon on June 25, 1944. A world war was raging on, my father was in...

    Anyone Using NEMA 23 Stepper Motors in Robotic Applications?

    Using stepper motors in a closed-loop, negative feedback environment is different than doing a similar implementation with servo motors. I have designed and built and troubleshot systems using both, but steppers are tricky to use for closed-loop position control. A lot depends on your choice of...

    Math Severity as applied to Serious Electronics

    This "job" will soon be performed by the likes of Elon's Optimus humanoid robot. I think the key to short-term (next ten years) employment is versatility. Specialization is for ants and bees. If you want to stay with electronics, I would consider making a "niche" item you can make inexpensively...

    Electronics seems like magic!

    I wonder if "Omega Supreme" is related to "Alpha Minor" or is it just coincidence?

    Electronics seems like magic!

    But only if you then plug it into a convenience outlet in the US of A. :cool: Woops! I promised myself I wouldn't step in this BS thread [looks at bottom of feet and frowns].
