I mention that I found a YouTube video which has a look at it: Octopus Hand supports Soldering for only 5$ – Turtle Review but like me they couldn’t figure out what the rubber and bolts on the base are for! If you know please let me know in the comments!

In this video we take a look at my new Peak Electronic Design Atlas LCR45 LCR Meter.

If you’re interested I have other equipment from Peak Electronic Design.

Over on the EEVblog forum I ask What’s special about the frequency 14.9254 kHz? The answer seems to be that this is 1/67th of 1 MHz, which is probably as precise as the microcontroller they’re using can go.

You can learn more about my ALKOY Capacitor Discharge Pen.

There are accessories available for the LCR45. Stuff I am planning to get includes:

I would get the LX30 – Extension Cable for LCR40/45 but it doesn’t appear to be in stock.

There are cases available but I am not planning to get any of those:

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).
