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.

We use the METCAL PS-900 Soldering Station to solder our cables.

We use the EEVblog BM2257 Digital Multimeter to test voltage and continuity.

We use the Horusdy Soldering Station with Hot Air Gun to shrink our heat shrink.

Channel News #6: I Have a New Gig! Also I’m Planning Some Things | In The Lab With Jay Jay

In this video I report in about what’s going on around here.

My big news is that recently I got a gig working for Hackaday. You can find my articles over here: https://hackaday.com/author/JohnElliot

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 new book teardown which I am going to need to re-record is for Electricity and Magnetism 3ed.

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.
