@CircumjovialLLC What an iconic model, absolutely beautiful
Oh, and I recently picked up a new (old) oscilloscope. Since I've started working on power electronics, I needed a 4-channel scope, so I finally pulled the trigger😊 500MHz bandwidth is so nice. It can be mod into 5GSa/s with replacing config resistors btw, will try that later XD
@Dave_Cawley You may want to double-check this modification on EEVblog to confirm that it actually works, as I'm not 100% certain about it
@Dave_Cawley FYI, Replace the yellow-marked component(s) as follows:L1: 15 nH (?) → 10 nH Replace Two Identification ResistorsTop side (near the CPU):Resistor marked L1: 100 kΩ → 10 kΩ Bottom side (near the CPU):Resistor marked L1: 10 kΩ → Remove (Do Not Populate / DNP)
@psycho_fren Thanks! I've learned a lot so far, and I'll be sharing more about power electronics as I continue learning.😆
Over the past few months as a Semiconductor Applications Engineer, I've learned a lot about datasheets and ATEs (Automated Test Equipment). Naturally, I ended up building a similar setup at home—except I vibe-coded it with Codex instead of using LabVIEW :p Here's a ripple test:

@rei_512_ はい、グネグネは 2 並列のシャント抵抗ですね!マルチメーターだと値が測れないくらい低抵抗です。 トランス前の抵抗アレイの方は 72kΩ くらいで、120V レンジ用の分圧ネットワークの一部じゃないかと思ってます

Having fun with ESTKme! 😃 It a way you can store 15 eSIM profiles on a physical SIM
@buildWithDeclan @i_anonimni it doesn’t have FDCAN peripheral
Done. Manufacturing is underway. My first PCB of this year. An external exhaust valve controller for my car.😇 Dual FDCAN and LIN transceivers, STM32G474 MCU core and ESP32-C3 wifi module.
Exhaust LIN frame captured and variations are as expected. I’m building another PCB with LIN transceivers
This project is now open source, everything’s up on my GitHub. But still haven’t had time to write any docs though. If you noticed I went quiet on X, I’ve begun my career at a major semiconductor company and most of my work is confidential. :) github.com/TerayTech/Merc…
