A friend gave me an old defective ITT MX20 Multimeter.
The multimeter is still currently sold under various brands. It’s a very rugged, IP67, electricity oriented multimeter.
The multimeter, now in working order.

In the previous topic where I explained
how to create your BOM from the KiCad’s XML export, I mentioned my own script generator, written in Ruby, xml2csv.rb.
It’s nothing fancy at all and there are already tons of BOM generators out there, but it’s always fun to create your own tool, suiting your very own special needs.

In my previous entry on
how to generate a BOM in KiCad 4, I wrote about “KiCad BOM Wizard” from hashdefineelectronics.com which can produce both CSV and HTML output.
Their website is well documented. But I wasn’t able at first to use that script on my Ubuntu (xubuntu 16.04).

I’m switching from KiCad 3 to KiCad 4.
While version 3 offered a simple, quite un-customizable, CSV generated BOM, version 4 now only offers a raw XML export.
As KiCad website says:
BOM generation is extensible via Python scripts or XSLT, which allows many configurable formats.
“many configurable formats” This is great! It’s even possible to use any program or language other than Python and XSLT to translate the XML in whatever format pleases you.
The downside is, it requires additional steps before you can actually generate a BOM. It seems a bit complicated but it’s not. Read below.

Unfortunately, the PSU you just bought isn’t adequate for your Eurorack system?
It’s common to be confused by the “-V” label.
Yes, “-V” on a PSU is a “negative” output, but only compared to the positive output. Your synth needs more!
So, what is the difference between “-V” and “ground”? How to select and use a proper power supply for your Synth?

If you want to power up your Mini Dual Power Supply, you need to supply it with an AC voltage on its input.
You can either use a simple tranformer or, safer and easier to manage, use a AC/AC wallwart adapter.
It’s not easy sometimes to make distinction between an AC to DC adapter and an AC to AC adapter. They share the same form factor, the same look and feel. But there are clear indications to help you determine the type of each one.
Here’s a quick comparison between the two types with two example closeup pictures, one AC/DC adpater and one AC/AC adapter:
