Square mesh holders installed

I’m waiting for some more of these to arrive: Office Desk Pen Pencil Pot Ruler Scissor Cup Mesh Organize Container.

While I wait you can see in the bottom photo the bunch of tools without a home. In the pictures below I have circled in red the four mesh holders I have recently installed. They’re black on black so hard to see, sorry about that.

The two on the left are clipped on with zip ties. The other two are screwed in, one screwed into the second drawer and the other to some load bearing dowel I also installed today.

I’m a bit paranoid about the shelf my oscilloscope is installed in will come away from the wall, so I have buttressed it with a dowel I had them cut to size for me today at the shop (307mm, exactly).

In this video we demo the ANENG A3005 Pen Type Handheld Multimeter. This pen-type multimeter can do voltage, resistance, continuity, and diode testing, among other functions. It’s a 4000 count device, meaning it can display about three and a half significant digits, for instance values such as 3,999 or 3.999 or 0.001.

If you’re interested you can check out all of my equipment from ANENG. They make good stuff! Of particular note is my ANENG AN-999S Bench Multimeter and my ANENG BT189 Battery Tester.

If you’re interested in any of this tech you can find it at AliExpress:

In this video we do the 14th project from the Maxitronix Sensor Robot 20 (20in1) Electronics Project Lab Kit: Non-Touch Switch.

We use the UNI-T UTi260B Thermal Imager to monitor the heat generated by various components. We learn that the resistors emit a lot of heat.

We use the Fluke 17B+ Digital Multimeter to measure the current drawn by the circuits in both the on and off state. The current was 15mA when the LEDs were on and zero amps when they were off.

We use the Riden RD6006 Bench Power Supply to provide 9V for our circuit. The power supply reported the current draw as 13mA which was slightly less than reported by the multimeter.

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.

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.

In this video I take a look at God Created the Integers edited by Stephen Hawking and published in 2005.

Hawking’s other book which I mention in this video is On The Shoulders Of Giants.

I am sorry that my pronunciation of European names is kind of terrible. While working through the book I made some notes on my wiki about pronouncing various names: God Created the Integers.

At 12 hours (the YouTube maximum video length) this is my longest video so far! If you do watch the whole thing through to the end, you are my type of person, so please do let me know! :)
