In this video we put the Peak Electronic Design Atlas DCA75 Pro Semiconductor Analyzer through its paces.

My notes about this device are on my personal wiki, here: Peak Electronic Design Atlas DCA75 Pro Semiconductor Analyzer.

The DCA75 can measure triac and thyristor devices but the Peak Electronic Design Atlas SCR100 Triac And Thyristor Analyzer can do a better job of it.

If you want to measure zener diodes the DCA75 can do it but the Peak Electronic Design Atlas ZEN50 Zener Diode Analyzer can do a better job of it.

While reading the manual we learn about the PCA23 SOT-23 test adapter, while searching for that I found this behind-the-scenes deeplink from Peak Electronic Design: https://www.peakelec.co.uk/resources/pca23.html

The manual mentions the International Electrotechnical Commission – IEC 60617 – Graphical Symbols for Diagrams, which is an international standard for graphical symbols of electromechanical devices.

The support page is DCA75 (DCA Pro) Support, from there you can download software/firmware.

In this video I unbox my ATPK3 – Atlas Pro Pack – LCR45 + DCA75 + Case which I ordered recently from element14. This bundle includes:

I will do a demo of the DCA75 and LCR45 in future videos.

I haven’t seen GP23 batteries before, but apparently they are 12V and can deliver 23A. Seems like rather a lot!

I’m not sure what is special about the specific test frequency of 14.9254 kHz, but I have asked on the EEVblog forum.

Unboxing #20: METCAL PS-900 Soldering Station | 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.

In this video I unbox my new METCAL PS-900 Soldering Station which I ordered recently from element14.

I keep my notes about this equipment on my person wiki, over here: METCAL PS-900 Soldering Station.

Before I purchased this equipment I made some notes about my research and decisions and element14 had the best price by far.

As I mention in the video my new PS-900 soldering station uses the METCAL SmartHeat technology. You can read more about SmartHeat over here:

Per the above links the Metcal SmartHeat technology is available in various solutions:

The PS Series (which I got) is the entry level system. You can spend much more than I did!

I found this document Metcal – Tip Temperature Guide which describes the various tip options (Metcal calls the tips “cartridges”) along with their temperature specifications.

As promised the link for my electric scissors is here: Jackcat Electric Scissors.

Electronics Project #10: TJ-56-428 4-Digit Digital DIY Clock | In The Lab With Jay Jay

Silly Job Title: Switch Sleuth

Happy New Year!

In this video, my first video for 2025, I construct a 4-digit digital clock I recently purchased from AliExpress: TJ-56-428 4-Digit Digital DIY Clock Kits with Acrylic Shell, DIY Alarm Clock Soldering Practice Kit for Learning Electronics.

I thought it might be nice to kick off the new year with an actual electronics project, as that is what this channel is supposed to be mostly about!

I translated the instructions from Chinese to English, and those are here: TJ-56-428. These include instructions for use of the complete and fully assembled clock.

This was a great chance to try out my new METCAL PS-900 Soldering Station and I am pleased to report that I am very happy with my new soldering iron! It is a pleasure to use.

The heart of this circuit is the STC15W404AS which is a microcontroller! It has been pre-programmed with the clock functionality, there was no software or source code that shipped with the kit.

Update: my mate @sadata777 pointed out that there was a protective coating on the acrylic and I remove that in this video: https://youtu.be/y9btakLOCHc

Update: my mate Joe pointed out that I had the case on back-to-front which you can see me fix here: https://youtu.be/IyJ3IHgRfiw

Equipment from Peak Electronic Design

The British company Peak Electronic Design has a wonderful range of Test Instruments.

Today I purchased these ones:

Still on my wish list is this one:

The reason for this particular splurge is that after I purchased my METCAL PS-900 Soldering Station element14 sent me an email with a coupon for 15% off. Since these Peak Atlas devices were on my wish list I figured I might as well get them while I can get 15% off.

METCAL PS-900 Soldering Station

Update: my notes about my METCAL PS-900 soldering station are on my personal wiki, over here: METCAL PS-900 Soldering Station.

The other day I was doing some soldering with my Horusdy Soldering Station but I got the feeling its soldering iron was under performing. I just wasn’t getting good solder joints even though I was using good solder and plenty of flux.

So today I did some research and found myself a new soldering station: METCAL PS-900 Soldering Station. I found one for sale on element14 for AU$458.59 which as far as I can tell was a really good price. They were going for more like AU$700+ on Amazon, eBay, and even AliExpress.

I did also research and consider some other options from JBC, Metcal, Weller, and Hakko.

I also picked up a couple of spare tips:

The tip it came with was the METCAL SFV-CH10, 30° Chisel, 1.5 mm Soldering Iron Tip.

I am expecting that the 1 mm chisel tip is going to be my weapon of choice, so I got two of those. (Update: this was a mistake, the 1.5mm or 2mm option would have been a better choice.)

Conspicuously absent on this soldering station is a temperature setting. That’s because these METCAL irons come with SmartHeat technology, as ChatGPT explains. For the SFV-CH10 the Curie point is designed to maintain a nominal tip temperature of around 380 °C (715 °F) under typical load conditions.

In this video I open the stuff that has arrived in the mail recently:

I mention that I’m working on a new book teardown for God Created the Integers.

The epaper modules I’m working with are these ones: WeAct 2.9” 2.13″ 2.9 2.13 Inch Epaper Module E-paper E-Ink EInk Display Screen SPI Black-White Black-White-Red and the microcontrollers I’m experimenting with are these ones: WeAct ESP32 ESP-32 ESP32C3 ESP32-C3FH4 Development Board Wireless WiFi Bluetooth-compatible Module Micropython.

The Arduino Nano you see is one of these: Mini / Type-C / Micro USB Nano 3.0 With the bootloader compatible Nano controller for arduino CH340 USB driver 16Mhz ATMEGA328P connected to an OLED display like this: 1.3″ OLED Display Module White/Blue Color Drive Chip SH1106 128X64 1.3 inch OLED LCD LED IIC I2C Communicate.
