Hand soldering Surface Mount Devices (SMD) scares a lot of DIYers and Makers, but it is easier than what it looks like. Even sometimes, it’s easier than soldering Through Hole Components. Really!

A quick post about an old design.
This is a simple 3 mono input mixer.
3 Mixer Modules I use extensively

The Passive Multiple is the simplest module you can find in a Modular Synth. But you really need a bunch of them.

I’m working on improving my projects’ “documentation and build instructions”.
This is the next update:
LFO 1.1 BOM & doc 20161215
This is an updated documentation and build instructions for the Attenuator-Inverter module:

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?
