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.

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 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 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 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!

I accidentally happened upon this while surfing the interwebs this evening and I thought it was a great hack: EXTRA HANDS FOR SOLDERING – OCTOPUS. This person makes a very respectable third hand out of a few scraps.
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.
