Interested in USB Power Delivery. I don't discover products but discover bugs.

@aroerina2 テスター、すごくカッコいいですね！そう、5Aのe-marked USB-C-Cケーブルは電源と連動してこのように動作します。しかも、電力は単純に最大電圧×電流で計算されるのではなく、条件付きで計算されます。

ちなみに、emarkersを確認する際はご注意ください。非常に扱いにくいです！

A new gadget to review🤔 https://t.co/gR7bheryre

@Adam20751137231 Very close. 0.0336 Ohm = 33.6 mOhm😉

A sample of a 240W EPR cable. Found and reported some issues. Still waiting for some data from the provider.

INA226 vs. 34401A (100V range, 10 PLC). The INA226 with enhanced sampling algorithm has faster response time, slightly better stability, but a bit longer settling time. So, which one performs better?

Introducing my USB adapter/tester for isolated DC/DC converters & modules. One-way assembly, hard to get it wrong.

Hey, it’s time to extend the life of your idle USB tester!

Coming up next: PD 3.1 triggers, rookie USB tester, Shizuku vs. YR1035+ vs. DIY milliohm meter vs. milliohm meter module of my cable tester vs. reference milliohm meters, etc. Hopefully😆

Got a couple of interesting triggers and testers on hand, but don’t know if reviews will be released within this year.

It's been there for a while, just didn't get around to posting it.

Shizuku seems to work with any thermistor

An old project done a few months ago. I needed to deal with temperature measurement and found that Shizuku could use temperature sensor from Witrn-U2.

@Dezmond2014 Yup, exact same MCU with a bigger screen but same resolution. That means slightly lower display quality.

Seems to be the first PD 3.1 USB tester.

@Dezmond2014 Slightly different.

[Magicmeter @USBChargingBlog]

@Dezmond2014 Nothing fancy in the 10A ver. They simply replace the R012 current shunt with a R005 one, add a piece of thermal silicone pad, and remove the MFi function. Yes, r005 is too small to detect tiny currents. Also, be careful with U3, it can sometimes trigger high voltage on its own.

Something maybe you are interested in.

@Dezmond2014 Flash: 1024KB
RAM: 96KB/224KB

[Magicmeter @USBChargingBlog]

@Dezmond2014 240Mhz max, I believe.

[Magicmeter @USBChargingBlog]

@Sol_Huebner Yes. And when I measured the ripple of the charger in this review, I found that U2 would trigger a voltage exceeding 8V by itself.

This is one of the reasons why I don't do a review of it. What do you think?

Seems like false advertising. https://t.co/ePeHR43mWP

Will be writing a review on it.
