You might already know that I have the full set of Maxitronix Xin1 kits, but here are some photos of me unboxing my 200in1 so I could send some pics to my mate Dave Jones:

My day at ElectroneX with my friend

Posted on 2024-06-19 [Wednesday] by Jay Jay

Well. Wow. What a day!

Today was the opening day of ElectroneX in Sydney.

I had the great privilege of spending the day with my very good friend Aleksei. Between us I think we managed to talk to every single exhibitor. By the time I got home my legs were sore and my lips were parched, so much walking, standing, and talking!

I turned up in character. I wore my costume. A lot of people thought that was fun, as did I. :)

I met Dave Jones of EEVblog fame, which really made my day. I knew he would be there and I was really hoping to see him, and I did! He was nice enough to plug my channel, what an excellent human being! <3

And as if things couldn’t get better they went on and did! It was an honour and a privilege to meet Nicholas Vinen, the editor of Silicon Chip magazine. I had hoped that he would be there and I would run into him… and then he was and I did!

All round a super great day. I had a lot of fun, learned a few things about the state of the art, and I even netted a few new subscriptions on the channel. :)

Today was Spring cleaning day

Posted on 2024-06-18 [Tuesday] by Jay Jay

I had to get new batteries in four of my UPS devices which involved a lot of plugging and unplugging. Since I was down there under my desk I took some time to vacuum and do a better job of my cable labeling.

While I was sorting cables I found one with a frayed end which I decided to keep for spare parts. In makes me nervous just looking at this thing. That’s a mains power lead with bare ends, it’s a death sentence waiting to happen! But that bit of cable with that attachment might very well come in handy some time so I will file it in its relevant drawer.

Channel News #3: Announcing Mini Projects | Learning Electronics In The Lab With Jay Jay

In this video I announce the new Mini Projects. These are a new feature of Silicon Chip magazine sponsored by Jaycar. Each month two or three Mini Projects get published in Silicon Chip, and we will be building those projects together on the channel each month!

If you’re interested in Silicon Chip magazine (it’s really good!) then I would certainly encourage you to subscribe.

In this video I misspoke and said this was the “May 2004” issue of the magazine, but of course it is the “May 2024” issue of the magazine! Unfortunately I missed that errata during editing and didn’t include a title clip correction.

I don’t understand what happened that caused that video corruption we saw earlier in the video. I suspect the workstation I was using to record the video had some other processing task which interfered with its recording speed or something? Hopefully this is not an ongoing problem. It’s not a problem I have seen before.

Update: ElectroneX has now been and gone and my write up about the day is over here: My day at ElectroneX with my friend. I got my photo with Dave Jones!
