I think I found a motherboard worth considering: MSI B550-A PRO

It can flash the bios without a CPU installed, it has a good enough VRAM for non-overclocked (to lightly-overclocked) CPUs, good connectivity, Diagnostic LEDs, an ok price, and good reviews.

And this might be an unpopular opinion, but the ryzen 7 3700x from last generation is still a good CPU and offers better price to performance than ryzen 5000. So if you are after a good value that's it.

For Ram there are too many kits. You should look for something like:

• 2x 8GB (more if you want)
• 3200-3600Mhz
• CL16
• G.Skill, Crucial, Corsair, Kingston, ...

As a boot drive

• >1TB
• NVMe 2280
• PCIe 4.0 x4 or PCIe 3.0 x4 (PCIe 3.0 x4 should be fine)
• Samsung, Crusial, Kingston, Corsair, Western Digital, ...

I think you should wait to buy a GPU and make do with what you currently have in your build.

And you don't have to get a stronger PSU if you don't get a new GPU.

I hope this gives you some sort of direction to make your own decisions.

EDIT: I thought about it and the ryzen 7 3700x is a pretty nice option.

Saw this youtube claim for longest DRSSTC arcs at 3.48m:

I think Mads already had that beat.  Perhaps others too.

Isn't it meant like a record for himself?

This kind of trick works with most computer PSUs. As a tutorial here is one for an ATX PSU: On proprietary PSUs, it will probably be harder to figure out what contacts to jump.

Hi,

I guess the yellow graph is the Gdt output? I think that the voltage for the driver IC's drops too low during switching. Do you mind scoping the 12V on the driver IC? If thats the case a big cap might fix it.

Do you currently have any pseudoload at the bridge output? That could result in some spikes too.

You should twist the wires from the Gdt in the corresponding pairs. Twisting Green and White for example might even be counterproductive.

No lawyer, just an it student here. Therefore I can only comment on the technical aspects.

I wouldn't think they could just say the IP address in court with out the actual packet data.

Another thing to consider is that the public IP i.e. the one seen from the internet, belongs to the ISP. Most of the time the ISP uses 1 public IP to serve multiple endusers, meaning that multiple people connect through the same IP to the internet/look the same. The backtracking who sent the packet can only be done via the ISP. To my knowledge only enterprises have their own IP, which can be tracked directly to them.

To me it sounds like your friend used a torrent client, to download the game. Google "torrent filesharing" if you want an explaination, but in short by downloading something, others can download the same thing from you. For this to happen, you dont need to configure your router or any firewall. It happens pretty much on its own. So unfortunately she could have done it on accident. Although this would only work if her PC was running while she was away and starting the PC while not physically there would be pretty much impossible for a normal enduser. No VPN would make that happen.

Do I understand correctly: A lawfirm downloaded the game from your friend? To me it sounds like the lawfirm was fishing for a case.

I think you should contact a lawyer yourself.

Edit: You might want to post your problem on reddit https://www.reddit.com/r/legaladvice/. I think they can be of more help from a legal perspective.

PS: If you dont mind, keep us updated with how it plays out.

Isn't that a 1:1 Transformer? The white wire has 1 Turn on each other Core. You would need the brown wire to have a single turn on the middle core and the white wire one turn on the blue wire core.

That might be the source of your problems

Turns out it is not, my bad.

First of all I'm sorry if I seemed rude, but it happens too often that people ask for something without having done their own research.

At first you should think about what you want.

Do you want a working Induction Heather? Buy one from Ikea.
Do you want a bit your DIY? Ebay-Kit.
Do you want to dive into inductionheaters? Read something first and then decide.
Do you want to make everything (PCB, soldering, ...) yourself? Start with a simple circuit and in the future worry about power.
...

My opinion is that you should start out simple and then improve/make your system more complex. This way you can learn a lot more than by building an UD-kit coil.

With the driver board do I have to have an interupter and is a interupter just for music and what is arc extenguishing feature. I know what arc extengusing is on spark gap, but on sstc what does it do.

If you want to build a sstc (one resonant coil) you probably dont need an interrupter (most designs dont, but some do), with a drsstc (two resonant coils) you probably do need an interrupter.

A use for an interrupter is the music functionality. Other uses of interrupters can be to limit heat production in sstcs. For drsstc you have to have an accurate interrupter, which can vary the ontime and not just the frequency.

Arc extinguishing is probably the detection of groundstrikes and then an interrupter pulse, to kill the arc and prevent excessive current draw. The UD2.X doesn't have this feature and it works good enough.

Would this be close to correct. Need power supply for the igbt, need the driver board to fire the igbt. What is the frequency limit of the  UD2.5 driver board. Just trying to get a simple block diagram of sstc in my brain. This is going to be next prodject. So much info and bad info it really is making me pissed.

Have a look at this diagramm from the book: DRSSTC BUILDING THE MODERN DAY TESLA COIL

The diagram isnt perfect (like the feedback is commonly on the primary) but it should give you a good idea.

btw I can recomend the book for further reading, also you might want to check out mads drsstc and sstc design guides, or loneoceans sstc II guide.

It is most likely part of the interrupter/driver curcuit, but the "stealing" could look cool too. Especially as the brightness will vary, depending on the fieldstrength.

It would be enough to have a few loops of wire soldered to either leg of the led. You will need to experiment how big the loops and how many turns light the led brightly, without killing it.

I found a video that helped me when getting started with sstcs: https://www.youtube.com/watch?v=gZXYpAr_T0A
He explains a few things surrounding gdts and where to get cores. I have to add that for a drsstc you should have a better gdt than what he is aiming at.

Some thing you should think about:

• good core (there have been some examples already, I used the B64290L0674X830, there are many more good ones)
• wire (some people used ethernet cable, I don't like that, I used solid core PVC wire, the cheap one, and twisted 4-6 x2 lengths together before winding)

This is my latest gdt. It uses a core out of an old car amplifier, which seems to work fine.
The primary side is double wound, while the mosfet/igbt end is just single. Both white wires are primary and the red ones are the two igbt ends.
