Silly Job Title: Component Wrangler

In this video I add improved debouncing logic to the inaugural Silicon Chip and Jaycar Mini Project: JMP001.

Shout out and thank you to Tim Blythman for developing this project.

You can see Tim’s original code and my updates which improve the debouncing implementation.

In the video I mention that we use the pgmspace.h header from Arduino.

In this video I unbox my new Fluke 17B+ Digital Multimeter.

The hard copy manual which was in the box I received was in Chinese (I think) but I found the English documentation available on the web from the manufacturer over here: Fluke 17B+ Digital Multimeter.

Shoutout to my mate @ElectrArc240 who was the person that made me aware of this Fluke multimeter, I learned about it in one of his videos.

If you enjoyed this video and are interested in the Fluke 17B+ you can see a product demonstration over here: Demo #1: How to Use All the Features of the Fluke 17B+ Digital Multimeter | In The Lab With Jay Jay.

Interlude #8: Making My Maker Faire ‘Here There Be Makers’ Badge | 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 I fix up and reassemble my Here There Be Makers badge which I received from Maker Shed in California.

John's Makers PCB badge

This electrified badge was made by lectrify.it and PCBWay.

Previously I had installed a single 3mm LED in the top of this thing, but in this video I remove that (so I can use the hole to hang it) and install two 3mm LEDs on the front instead, which is my best guess as to what I was supposed to do with this thing, which didn’t come with instructions.

There is some information about their Maker Faire event on in San Fransisco later this year over here: https://make.co/welcome/

And also, yes, I should have combed my hair before making this video. :P

This is an old video I found while tidying up my files today. I recorded this back in September 2023, around about a year ago. Figured I might as well publish it on Elliot’s Extras.

In this video I unbox my Yum Cha M6013 Capacitance Meter and my Yum Cha MESR-100 ESR Meter. Then I attach some banana plugs to one of my Yum Cha Probe Tweezers.

Symbol Keyboard | Mini Project JMP001 | Learning Electronics 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.

This is the inaugural Mini Project! I introduced the Mini Projects recently. They are developed and published by Silicon Chip magazine, and sponsored by Jaycar Electronics (which is an Austrlaian electronics store, similar to Radio Shack in the USA, hopefully it doesn’t end up suffering the same fate.)

In this project, codenamed JMP001, we develop a USB keyboard which can send interesting and unusual symbols (which aren’t usually available on a keyboard) to a Windows computer using the alt-codes that it supports in a typical codepage.

For this first Mini Project I felt it was important to actually buy my components from Jaycar which I did for roughly eighty Australian dollary doos. Approximately US$50. The parts I ordered were these:

Belatedly I did also search for rubber feet.

There was quite a lot that went into the production of this video, and we accumulated a lot of links. Those are here:

In the end this first project was relatively successful, and we did get it to work fairly well on one of my Windows computers. As for the rest you can find out for youself in the video!
