In this video we make a cable to connect a 6V battery pack with a 9V adapter to a USB Type-A female socket, which we can then use to connect a USB Type-A male through Type-B micro for powering my microcontroller.

I mention that I am reading AVR Programming: Get Under the Hood of the AVR Microcontroller Family which is written by Elliot Williams who is Editor in Chief over at Hackaday. The big thing I am hoping to learn from this book is how to generate tones, but I haven’t read that part of it yet!
The old book teardown which I have been working on is for Electric Circuits.
I have done the introduction for the Maxitronix 30in1: Introducing Maxitronix 30in1 | Maxitronix 30in1 | Learning Electronics In The Lab With Jay Jay but I haven’t done the first project yet. The thing that is tripping me up is making a decision about whether I am going to start doing the LTSpice simulations in the 30in1 videos or if I’m going to put that off until we start our next Maxitronix kit… I will have to make a decision about that soon.
I am working on Jaycar and Silicon Chip Mini Project number JMP003. But I’m stuck debugging it. I hope to catch up with that soon. I have heaps of Mini Projects to do, I am embarrassingly far behind.
I have recorded the introduction for the Learning the Art of Electronics project that we’re just about to kick off: Introducing Learning the Art of Electronics | Learning Electronics In The Lab With Jay Jay but I’m still waiting for the 2nd edition of the book to turn up. Fingers crossed it gets here in the next couple of days otherwise I will need to start on this project using the 1st edition of the book.
There’s a bunch of stuff here that has arrived in the mail so you can expect to see a mail call video covering that stuff soon as well.

We will be doing a total of 27 videos for this feature. 25 labs, this introduction, and a conclusion. Videos will come out on the first Tuesday of every month (hopefully!).
Also a shout out to my mate over on Learning as a hobby for encouraging me to undertake this project.

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.

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:
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.
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.
