The US stock market was due for a correction so pick your excuse and the speculators love a crisis to make a $  :horse: Not to mention what spooked it in the first place. Miracle @ 1600 :palm:

Fresh air and Sunshine after re aligning my Laser and testing it. I have a bunch of 6mm Acrylic to cut next week so the poor little 40W needs all the tweakage it can. 4.5mm Acrylic Router Template test cut.

Only 10 more corners to do .....

BTW Do I need to get out of Bed early tomorrow for Discord or can I  :=\ ?

Yes, I don't like change either but I guess you get used to a new design. It's the functionality that's the issue for me. The update now opens each group automatically, ie beginners, products, computing etc meaning you need to scroll a lot more or minimize each time. The most frustrating thing though is if you open an attachment/photo and then go back, instead of returning to where you were in the page at goes back to the top of it. A pain in the arse if you were down near the bottom of the thread.

Thats also my main issue with the new version :(
I use always the "recent unread topics", and then I scroll down, when I then see something interesting, clicks on it, reads the posts and clicks "back", I will return to the top of the page. The old version would get me exactly at the same spot so I could just scroll on from there. Very annoying.

Beginners / Re: Induction Heating Circuit
« Last post by Berni on Today at 09:02:12 am »
I've downloaded LTspice yesterday and I've had quite a lot of educational fun. I've rebuildt different kinds of induction heaters and am pretty fascinated by how the software gets basically every physical aspect right.

Thank you all for your replys

Yep this is how most people design analog circuits. Its so much easier to play around in SPICE to figure out how it all works before actually building it for real.

But be careful about how you interpret the results from LTSpice. Just because it works in the simulator does not mean it will work in real life. In simulation components can never blow up no matter how overloaded they are, wires have zero resistance and zero parasitic inductance/capacitance, components have perfect values with no tolerance... etc. So if you do get odd behavior in simulation its likely due to one of those aspects of the simulation being too perfect compared to real life.

Based on your previous posts and their tone I would have thought at best is was attempted sarcasm or maybe a poorly attempted put down of what Brumby needs the GPU for. What you consider a joke doesn't always translate from your keyboard when put in context!

Maybe you should get involved outside the Buy & Sell section there is a whole lot of forum out there. Who knows you might even find a new rule to try and tell other people how to behave ::)

Test Equipment / Re: Rigol MSO 5000 hardware/software revisions
« Last post by jemangedeslolos on Today at 08:52:15 am »
The release notes are a copycat of the MSO8000 release notes.

Sighound36 installed the new FW in MSO8000 and noticed many improvements that are not listed in the release notes.

So, the 8000 notes are wrong or, the 5000 may also have some easter eggs.

I don't know if this is good news or not.
I am happy that there are improvements not listed but it gives us the impression of amateurism from Rigol....
Considering the work involved in fixing bugs, lsiting them properly is the least of things.

I can't wait to test all this but my MSO7000 has been going around for 6 days in Amsterdam so I think DHL has lost my package but I won't know until next week  |O

Metrology / Re: AD587LQ

I had a second look. Despite two metal layers and low resolution, after some digital enlargement the image is surprisingly readable.

Need more resolution?

I found out how to fix it using the PC software for the FY6900. When I first ran the software some functions like update firmware or the PC software didn't work. Later I read on eevblog that you need to run in in Admin mode. Curious as to why, is the software doing anything nefarious? Anyway after running it in admin mode I tried to update the firmware but it said my current 1.3 version is the latest.  However others have said there is a 1.4 version. I noticed on option under the help menu to "repair sine". I ran that one and the problem is fixed.

Obviously Feelelec is aware of the problem since a fix is in the PC software. It don't have a good feeling about the problem staying fixed. Am guessing that something is getting corrupted in the flash/firmware causing the sine wave problem. What else is getting corrupted? Why can't it be permenantly fixed in new firmware, because it's really a hardware problem?

KiCad / Re: Schematics conversion into valid Verilog code
« Last post by Doctorandus_P on Today at 08:43:28 am »
I also like KiCad, but never used Verilog and do not know what such a program should do.

As KiCad is fully Free & Open Source software there are a lot of "side projects" around KiCad. From extracting component data from PDF's. scripts for generating netlists, tools for generating different kind of BOM lists and many more.

Some are well maintained, others are in varying levels of bitrot.
I've seen pages on github where some people kept lists of such tools of external projects around KiCad.

File formats in KiCad are also Open and pretty easily readable ASCII, and tools / libaries for writing those files are of course also a part of the KiCad project.

But what sort of level of conversion are you looking for?
Just a netlist thing, or do you want it to automatically insert a softcore if you use a uC in your schematic?
