Silly Job Title: Code Warrior.

Super big thanks to my new Patreon supporters Ali and Learning as a hobby, it’s really great to have your support, thank you!

In this video we have a look at what has arrived in the mail:

I mention about the ITL Wiki and my Learning the Art of Electronics project, the first lab should come out for that this coming Tuesday, fingers crossed!

Also I mention about the project from Willow Cunningham which is PentaPico: A Pi Pico Cluster For Image Convolution and is what I got my RPi Picos for!

Silly Job Title: Bit Distinguisher.

In this video we build an LED heart. It is beautiful and green.

The schematic and instructions are these:

Instructions in Chinese

Schematic in Chinese

As we discover in the video this circuit is an astable multivibrator made with two op-amps provided by an LM358.

I mention that my copy of Learning the Art of Electronics: A Hands-On Lab Course 2nd Edition has arrived. Very happy about that! I will be getting on with the notes for these very soon.

I mention about the two Logitech BRIOs that I have installed as my “maths cam”. This will enable me to record my maths videos, which I am planning to start soon. I will be working through my old high school mathematics textbooks starting with Signpost 7.

I mentioned my Spivak calculus book, and my Stewart calculus book too, but I can’t seem to find my copy of that at Amazon. If you’re interested in such things check out Calculus by Spivak from Learning as a hobby.

We use the METCAL PS-900 Soldering Station for soldering.

We use the Peak Electronic Design Atlas DCA75 Pro Semiconductor Analyzer to check our NPN transistor.

We use the Peak Electronic Design Atlas LCR45 LCR Meter to check our resistors and capacitor.

We use the Riden RD6006 Bench Power Supply to provide 5V for testing.

We use the Yizhan Digital Microscope to have a closer look at a few things.

We use the Hakko CHP 3C-SA Precision Tweezers for working with small parts.

I mention about these bins which I have purchased recently. They are cheap and a good size but my experience is that the material is very brittle and prone to breaking.

And love to Nirvana for Heart-Shaped Box. 💕

Also, here’s the full list of my ESP32 boards:

Electronics Project #11: TJ-56-428 4-Digit Digital DIY Clock Take 2 | In The Lab With Jay Jay

Silly Job Title: Wattage Warlock.

In this video we build the TJ-56-428 4-Digit Digital Clock just like we did last time.

You read that right. We made one of these before and I liked it so much that we are making one again! I get better at it this time round, I don’t make any of the mistakes I did last time.

In the introduction to this video I mention about my new Blu-ray player which I got so I could watch Colossus: The Forbin Project. Both my Blu-ray disc and my Blu-ray player are for Region B.

As I mention I have been writing for Hackaday! So that’s been keeping me busy.

The instructions for this clock are over here: TJ-56-428 4-Digit Digital DIY Clock (same as last time).

I mention about the new Learning the Art of Electronics project which we’re just about to get started with.

The microcontroller in this clock is the STC15W404AS. It comes in the kit pre-programmed and I’ve not been able to find the software anywhere. Bummer. If you know where to get the software please do let me know!

The temperature controlled resistor is a 10K NTC thermistor which seems to be used for the room temperature function (which I don’t use and didn’t calibrate).

The crystal oscillator is spec’ed as 32768 which is obviously a reference to the clock frequency. See Why do we use 32.768 kHz crystals in most circuits? We check the impedance of this device in the video using the Peak Atlas LCR45.

In the video I mention my mate Joe who helped me out last time I did this project. Thanks Joe!

We use the METCAL PS-900 Soldering Station to do our soldering.

We use the Fluke 17B+ Digital Multimeter to test the voltage on our USB power adapters.

We use the EEVblog BM2257 Digital Multimeter to check our resistors.

We use the Peak Electronic Design Atlas DCA75 Pro Semiconductor Analyzer to test the crystal (we don’t get a reading, which was expected).

We use the Peak Electronic Design Atlas LCR45 LCR Meter to test our crystal. It gives us an impedance reading at 200kHz with both real and imaginary components.

We use the Hakko CHP 3C-SA Precision Tweezers to hold our solder and poke about. At one point I drop a component lead offcut into the board and it shorted two resistors, so lucky I found it and pulled it out!

And that’s everything to know about this project!

Here’s a photo of the completed project installed next to the symbol keyboard on my desk:
