Good news everyone!

The In The Lab With Jay Jay website has been freeloading off jj5.net for a while now, over here: https://www.inthelabwithjayjay.com/in-the-lab/

But I am pleased to announce that it has now been moved into its new and permanent home, over here: InTheLabWithJayJay.com

There is also a short-link domain which will redirect you to the new site which I put into production to keep the links on my business cards short: jjlab.net

Speaking of business cards I had some made to take with me to ElectroneX on Wednesday:

John's new business card for In The Lab With Jay Jay

I’m planning to show up in costume and hand out business cards, because I am a *genuine* nerd.

As part of the migration to the new domain I improved the content of the site a bit. There is now an about page with contact info and such and also a support the show page with some ideas about how people can support the show!

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!

In this video I put a 2k potentiometer in series with a piezoelectric buzzer to act as a volume control.

I got some help with this simulation over on the EEVblog forum: Help with modeling multivibrators in LTspice.

There are some important errata concerning the above over on the EEVblog:
