Demo #8: Unboxing and Product Review of Rown Fusny R03U Wireless Mono Headset | In The Lab
This post is part of my video blog and you can find more information about this video over here.
You can support this channel on Patreon: patreon.com/JohnElliotV
In this video we unbox and demo the R03U Wireless Mono Headset sent to me for review by Rown Fusny. This headset supports wireless connectivity for both USB and Bluetooth. I really enjoyed using this product and their customer support was first class.
It’s a mono device which means it only has a speaker for one ear, which is really good for your situational awareness because you can hear what’s going on in your environment through your other ear. Both the headphone and the microphone worked properly in both USB and Bluetooth mode.
I wasn’t able to get the USB mode to work on my Windows 10 machine, but I don’t know if that was related to the USB hardware on that computer or if it had to do with Windows 10 support for the device. I was able to get USB mode working on a Windows 11 Pro computer and one of my Debian 12 (bookworm) computers. I tested the Bluetooth mode on both iPhone 6s and iPhone 8.
One thing that I needed explained to me was that after you pair your Bluetooth device you may need to double click the power button on the headset in order to toggle from USB mode over to Bluetooth mode in order to activate the device. That’s why I had to contact customer support, because I was confused by this.
The device gives you status updates via audio. So if you toggle to USB mode it says “USB mode” and if you toggle to Bluetooth mode it says “Bluetooth mode”. If you disconnect the USB dongle or unpair the Bluetooth connection it says “disconnected”.
There is a microphone mute button on the headset and there are volume control buttons too. I tested the volume control buttons via Bluetooth but forgot to test via USB… hmm. Gimme a tick. Yep, the volume controls work on USB too!
Overall I was very pleased with this device and I would happily recommend this product!
In preparing this video I made some notes about my headphones which are still available on my wiki.

Analog Meters for Learning the Art of Electronics
I was flipping through my copy of Learning the Art of Electronics: A Hands-On Lab Course (I have the first edition, this second edition comes out in Australia on 3 April 2025, I have a copy on pre-order, I think it’s already available in the USA) and I noticed that some analog meters are used in the first lab course.
So in preparation for doing that I purchased some analog meters, being these:
- DC Ampere Meter 91C4 Ammeter 1/2/3/5/10/20/30/50/100/200 A V Voltmeter Analog Panel Meter Mechanical Pointer 91C4 Ammeter (5V, 10V, 15V)
- 91C4 Class Ampere Analog Panel Meter Ammeter 2.5 Accuracy DC 50uA 100uA 200uA 300uA 500uA High Quality (100uA)
- 91C4- mA DC Pointer type milliammeter 1mA 5mA 10mA 50mA 100mA 200mA 300mA 500mA Analog Mechanics Plate table Ammeter (1mA, 10mA, 100mA)
- 91C4 Ammeter DC Analog 1A 2A 3A 5A 10A 20A 30A 50A 100A 200A 300A 500A Panel Mechanical Pointer Type Amper Meter Current Meter (1A)
I am planning to start working through these projects on my YouTube channel @InTheLabWithJayJay at a rate of one project every 28 days starting April 1st. April 1st, being April Fools’ Day, is of course the traditional date for launching IT projects and it is also the one year anniversary of my video (which happens to be my most popular YouTube video by a large margin): New Book Teardown #3: Learning The Art of Electronics: A Hands-On Lab Course (2016) | In The Lab.
Interlude #14: Making BNC to Jumper Pins Cables for My Oscilloscope | In The Lab With Jay Jay
This post is part of my video blog and you can find more information about this video over here.
You can support this channel on Patreon: patreon.com/JohnElliotV
In this video we make two cables for use with my oscilloscope or other devices with BNC sockets. The cables have a BNC connector on one end and two male jumper pins on the other end. This is so that I can easily connect my oscilloscope (or signal generator) to a breadboard.
Equipment which I might use these new cables with includes my Rigol MSO5074 Mixed Signal Oscilloscope and my UNI-T UTG962E Signal Generator.
In the video we use the METCAL PS-900 Soldering Station for soldering.
We use the EEVblog BM2257 Digital Multimeter to continuity test the cables and to check for shorts.
We use the Horusdy Soldering Station with Hot Air Gun for shrinking out heat shrink.
We use the Hakko CHP 3C-SA Precision Tweezers for pulling the heat shrink over the wire.
