Goal is to prep all the connectors. on the mixer switch project.

Hi everyone, I am going to be starting to work on electronics.

A view showing the DC to AC converter, with the test setup. (Bottom to Top of image) Fluke Scopemeter 115, Fluke 87 V, PEAK POWER 800W DC to AC supply. Plugged in to it is a “Extech AC Line Spitter”
I was looking in to my old 800W 120VAC DC to AC supply, to see just how bad the square wave is.
The test in my view was not complete. I did not load test the supply. To see how the wave forms was effected. Due to missing Nut assembly for the Positive lead. I felt it would be unsafe due to insecure connection that could heat up due to possible arcing issues.
With the unit unloaded I proceeded to do a preliminary look at it with the 87 V, a digital meter. The 87, read that it was 120.2VAC and 61.12Hz.
With that I was curious what was going on with the waveform.
I hooked up the Scopemeter in to the mix. AC Neutral to Ground reference for the probe. The probe hooked in to the AC Hot on the line Splitter.
with that, I set the A input channel to 10:1 and took a look.
with that we see that it is going from +120V to 0 then -120V in reference to Neutral.
So I am looking to move away from Windows 2012r2 to a Linux stack to admin my windows boxes. So far I found UCS by univention. Based off Samba 4 it looks promising.
More to come as I dig deeper.
I was working on updating my hold music on my asterisk lines.
a quick method of doing this. Is as follows
First covert the audio to mono 8000 sample rate “wav” files
Then with sox installed
for f in *.wav; do echo $f ; sox $f -r 8000 -c 1 -s $f.sln -q ; done
rm -v *.wav
finally update the musiconhold.conf file with the directory of the processed files.
Thats it!
So I have been digging in to my past, as I have been performing a migration of archive data. To new hard drives. any ways you can see some of my Lighting design work here .
I have been studying Python, by reading Python Essentials by Steven Lott. It has shown me the basis of the language so far. Coming from a C background, I will be comparing data types to C data types.
The array data structures like Tuples, where you can set a static fixed list. Like
#C
static int myArray[3] = { 1,2,4,5 };
The list structures is very flexible similar to
int list[3];
the difference is in python you can add a element to the list without having a new object to move in to.
I find the Python language powerful, and it hides the nitty gritty. You do not have to manage your own memory.
It will be fun to learn. One goal I have for this is to rewrite my LED sign software.
