Demo #3: Peak Electronic Design Atlas DCA75 Pro Semiconductor Analyzer | 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 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.

Unboxing #21: ATPK3 – Atlas Pro Pack – LCR45 + DCA75 + Case | In The Lab With Jay Jay

In this video I unbox my ATPK3 – Atlas Pro Pack – LCR45 + DCA75 + Case which I ordered recently from element14. This bundle includes:
- Peak Electronic Design Atlas DCA75 Pro Semiconductor Analyzer
- Peak Electronic Design Atlas LCR45 LCR Meter
- GP23 battery
- AAA battery
- Case
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.

Ferromagnetic Substance Detector | Project 13/20 | Maxitronix 20in1 | 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 we do the 13th project from the Maxitronix 20in1 (the Sensor Robot 20): Ferromagnetic Substance Detector.
In this project we use the reed switch to detect magnetic material. We use an astable multivibrator to generate a tone which sounds when magnetic material is detected.
We use the Riden RD6006 Bench Power Supply to provide 9V for our test circuit.
We use the UNI-T UTi260B Thermal Imager to inspect the circuit board during operation and see the transistors for the astable multivibrator dissipating the most heat.
We use the Rigol MSO5074 Mixed Signal Oscilloscope to inspect the 1.5 kHz square wave which generates the tone for the buzzer.
We use the Fluke 17B+ Digital Multimeter to investigate some currents and some voltages into the base of transistor Q5.
We use the METCAL PS-900 Soldering Station to tin some wire for the DuPont-female jumper.
We also use a breakout board to add a volume control to the buzzer and to substitute a LED for the buzzer.
I really enjoyed this project, I think it’s the best one so far!

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

Magnetism Detector | Project 12/20 | Maxitronix 20in1 | 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.
You can support this channel on Patreon: patreon.com/JohnElliotV
In this video I do the 12th project from the Maxitronix 20in1 (the Sensor Robot 20): Magnetism Detector.
In this project we control a BJT transistor with a magnetic reed switch.
We use the thermal camera to observe heat in the transistors and LEDs during operation.
This is a plain DC circuit with no signals so there was no call for measuring anything with the oscilloscope.
I got myself a little confused about normally open and normally closed circuits during the video, but I think I was clear enough about that in the end.

Equipment from Peak Electronic Design
The British company Peak Electronic Design has a wonderful range of Test Instruments.
Today I purchased these ones:
- Atlas DCA75 Pro Semiconductor Analyzer
- Atlas LCR45 LCR Meter
- Atlas ESR70 Gold ESR Meter
- Atlas SCR100 Triac And Thyristor Analyzer
- Atlas ZEN50 Zener Diode Analyzer
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.
Pen Plotter Robot
I am so impressed! This guy made his own robot: story.md.
Electron Microscope
This guy fixed an old electron microscope which he picked up for free: I Saved an Electron Microscope from the Trash.
Decade Resistor Box
I got two of these Resistance Box 0-9999.9Ω Adjustable Lab Resistor Substitution Box Precision 1W Variable Knob Switch Boxes from AliExpress, but they kind of suck a bit. The resistors are only 1/4 Watt, the precision only 5% or 10%, and I had to mod it myself to replace the terminals with banana sockets.
Today I came across Build a Pro Decade Resistor Box for Cheap! PCB & 3D Print Files Included which includes all the plans necessary to make my own resistor box and with 1 Watt resistors.
I might take this on some time.
