Plan is to measure at LD+, LD- and RS+, all referenced to GND.
While the ground plane is low resistance, it is not zero resistance. In fact, it may even be comparable to the shunt you use, which will throw the current reading way off. If you want high accuracy, you want to sense the voltage across the shunt (directly - kelvin sense).

Have considered swapping the transistor(s) out for MOSFETs
I tried that. I couldn't get it to stabilize and actually popped a pricey diode when I THOUGHT I had it figured out . It can be done, obviously, as the flexmod is FET based. But it seems a lot harder for some reason.

Quote:
I have a real beefy TO-3 heatsink, easily big enough to handle the heat
The heat sink isn't always the limitation. It's sometimes the thermal resistance to case, and the case resistance to the heat sink when it comes to high dissipation. It is possible for the heat sink to be barely above room temperature, while the junction is over 100C. Just monitor the case temperature and don't start with full power.

I hope it has single shot. You'll want to capture power on, power off, quick power cycle, and rms noise at several different input voltages and output currents.

Good point, I'll look into a few options for that. I'd be happy if I can get it within 0.05V of the true value, not super accurate but good enough.

I tried that. I couldn't get it to stabilize and actually popped a pricey diode when I THOUGHT I had it figured out . It can be done, obviously, as the flexmod is FET based. But it seems a lot harder for some reason.


Hmm good to know you encountered issues. I've seen it done too, but perhaps there's something I'm missing. Something else to experiment with anyway. Hopefully I can get it figured out. Open to other ideas, no plans to make this a commercial product or anything, really it's just to give me something to do and to get some practice with designing my own drivers/PCBs. I feel I've learned a bunch already.



The heat sink isn't always the limitation. It's sometimes the thermal resistance to case, and the case resistance to the heat sink when it comes to high dissipation. It is possible for the heat sink to be barely above room temperature, while the junction is over 100C. Just monitor the case temperature and don't start with full power.

Good point, another reason to spread the load across several transistors and be conservative with current ratings. A quick calculation puts Tj at 91°C above Tc for 120W split across two transistors (Rθjc = 1.52°C/W), so that's looking at worst case, even if Tc is 50°C that'd still be 60°C below maximum. Power dissipation at Tc=50°C is still ~100W. Hotter than I'd probably like, but still within spec with some headroom left I should think.

That said, the MOSFET option is looking more appealing as I look at the base current numbers...


I hope it has single shot. You'll want to capture power on, power off, quick power cycle, and rms noise at several different input voltages and output currents.

Nope, it's ancient, it'll catch any major noise or oscillations, may catch any big ON/OFF spikes. A more modern scope is next on my list of tools, just need to save some cash and find a deal.

Thanks again for your input Cyp, I'll work on another revision or two of this over the next couple days, taking note of your suggestions as best I can. First for an update is transistor drive... This is getting more complicated than I had originally thought, not complaining, I can learn more this way.

Nice work diachi , hope it turns out well : D

Just finished my vacuum chamber to vacuum a few X Ray transformers in , its made from a old air compressor cylinder , lid is 20mm acrylic plate , gasket is nitrile rubber and PVC tape .

Work well so far : D

Sincerely investigate any of these three short quotes as new concepts and you've taken your first step into a larger world:

"I regard consciousness as fundamental. I regard matter as derivative from consciousness..." - Max Planck. "Everything we call real is made of things that cannot be regarded as real" - Neils Bohr. "What we call physical things and events do not exist independently of subjective experience..." - Deepak Chopra.

Each of these three rabbit holes go deep, ending up in the same place.

That photo is much different than the ones we are used to seeing here in the states of Iraq. I wonder how good the Italian food is there. It appears that the Iraqis are trying to appeal to American tastes.

This is in Kurdistan territory, they want to be the next Dubai. Although part of Iraq, most individuals here do not see themselves as part of Iraq and "Kurdistan" instead. They hope to break off from Iraq to be their own country someday. I also hope that happens, they want it and the people are different here than many other parts of this country. Mostly Christian too, instead of Muslim. That alone is a big divide between the rest of Iraq.

Hey guys, been reluctant to upload the photos I've taken recently because there's lots and it's tedious uploading them, but I really wanted to share this one because I'm super super proud and stunned. This is my first true attempt at photographing the Milky Way core, less than a year ago I knew nothing about astrophotography and this is where learning on my free time has brought me. Took this in fairly light polluted skies on a beach in Playa Del Carmen, Mexico. This is where I did my first attempt because the Milky Way core is high in the sky at that latitude, as opposed to up here where the core barely peeks above the horizon at best. 16 stacked images to reduce noise, I was battling 90% humidity and constant clouds, and the light pollution made the raw frames almost completely white. I made sure to not completely overexpose the photo, however, so I could keep all the detail. For those who want the deets, sixteen identical 10 sec exposures, ISO 6400 and at f/1.8 with my 35mm portrait lens, 1.5x crop sensor too.



Had to downsize, so think of that as like a thumbnail. The original is like 2100 x 1500. Heres the full res, would recommend/10

Wow is the first thing that came to my head when I saw that pic Gabe. Amazing! Just think that our recent discoveries could place planets around nearly every single one of those points of light you see in that image.
Pics like this make me wonder how some people can show no interest in space whatsoever.
I've given out too much rep, but I will return to rep you Gabe.

I've given out too much rep, but I will return to rep you Gabe.
Thanks so much! Same here rep-wise
And crazier to think of how small of a part of the universe this snapshot is, when there are to our best guesses roughly 1,000,000,000,000,000,000,000,000 stars in the observable universe, and probably many times more planets.... just incomprehensible!

Absolutely. The numbers are stacking up more and more as our technology is getting better at detecting them. To think that a vast majority of those planetary systems also have one of more planets in the so called Goldilocks zone.
It is rather unbelievable. One of the reasons why I am in favour for us not being alone.

Took this in fairly light polluted skies on a beach in Playa Del Carmen, Mexico. This is where I did my first attempt because the Milky Way core is high in the sky at that latitude, as opposed to up here where the core barely peeks above the horizon at best. 16 stacked images to reduce noise, I was battling 90% humidity and constant clouds, and the light pollution made the raw frames almost completely white. I made sure to not completely overexpose the photo, however, so I could keep all the detail. For those who want the deets, sixteen identical 10 sec exposures, ISO 6400 and at f/1.8 with my 35mm portrait lens, 1.5x crop sensor too.



Had to downsize, so think of that as like a thumbnail. The original is like 2100 x 1500. Heres the full res, would recommend/10
so sharp, much pixel, very resolution. Wow!

Nice shot Gabe.
The Milkyway core is amazing to shoot.
It's breathtaking to realise how many stars are in there.

For God so loved the world that He gave His only begotten Son, that whoever believes in Him
should not perish but have everlasting life.
For God did not send His Son into the world to condemn the world,

but that the world through Him might be saved.
“He who believes in Him is not condemned;
but he who does not believe is condemned already, because he has not believed in the name of the only begotten Son of God.
And this is the condemnation, that the light has come into the world, and men loved darkness rather than light, because their deeds were evil.
For everyone practicing evil hates the light and does not come to the light, lest his deeds should be exposed.
But he who does the truth comes to the light, that his deeds may be clearly seen, that they have been done in God.”
(John 3:16-21)
─────────────────────────────────☀
If you confess with your mouth, “Jesus is Lord,” and believe in your heart that God raised Him from
the dead, you will be saved.
For it is with your heart that you believe unto righteousness
and it is with your mouth that you confess
your faith and
are saved.
(Romans 10:9-10)
