Which meter branding does it have? --- End quote --- It's installed, and it has the ST branding on it. --- Quote from: GnomeZA on January 12, 2024, 09:25:54 pm ---How on earth did you get this? ;D --- End quote --- The ST people are AWESOME, that's how. That's why when anybody asks, I tell them to get the ST version if they can. The TH people will straight up ignore you until the end of time. --- Quote from: GnomeZA on January 12, 2024, 09:25:54 pm ---Any chance you could do some testing on that baby? --- End quote --- I plan to. 😉 |

Hopefully we'll have a slightly different model's improved version if our friend @tv84 has some time. 😉 --- End quote --- Here, test and report. --- Code: ---Header: 414243446C0B070024951300 Signature: "ABCD" (MAGIC OK) Block1 Size: 00070B6C [00000018-00070B83] Block1 Checksums: 385C [00070B84-000743DF] Block2 Size: 00139524 [000743E0-001AD903] Block2 Checksums: 9CA9 [001AD904-001B75AC] Block1 - Checksum is OK! Block2 - Checksum is OK! --- End code --- |

Well, looks like things are better than they were for sure. This certainly appears to be the best firmware yet. The bigger issues like 100Ω DCR and 100kΩ at 200kHz both look better. The ~700mH inductor looks better than it was, but it still appears to be too far of a jump between those frequencies. Results attached. |

Very promising! --- Quote from: KungFuJosh on January 13, 2024, 02:00:09 am ---The ~700mH inductor looks better than it was, but it still appears to be too far of a jump between those frequencies. --- End quote --- Ah you mean its inductance looks completely different between 1kHz and 10kHz? With inductors and changing frequency like that, I would expect some inductors to behave in unexpected ways. So I'm not completely sure whether to think this is a meter/calibration issue or more data needed. Don't get me wrong, I'm not writing this off, just trying to think through it in my head. All of this said, the results still look incredible! |
