Modular on the Lounge - second meeting

A great night had by all.

Visuals were provided with a LZV Vidiot video synth

We will try to hold these events regularly ... every 2 to 3 months

Jerusalem - Mount of Olives Cemetery, Israel.

This is the most important cemetery in Jerusalem. It started during the first Temple period and It is still being used today.


The cemetery contains anywhere between 70,000 and 2 or 300,000 tombs

 During the First and Second Temple Periods the Jews of Jerusalem were buried in burial caves scattered on the slopes of the Mount, and from the 16th century the cemetery began to take its present shape.
(Wikipedia)

..: According to Jewish tradition, it is here that the Resurrection of the Dead would begin. The Messiah would appear on the Mount of Olives and head toward the Temple Mount.

tHE Warriors - Larry Niven

 This issue of IF - Science Fiction magazine (Feb 1966) is the first time the Kzin are mentioned.

They are technically vastly superior to mankind and almost kill humans in their first encounter in deep space.
 
The Kzin have gravity drives and telepaths. After reading the minds of the humans on the ship "Angel's Pencil" they realise that the humans dont have weapons and have been a peaceful race for hundreds of years.










They decide to kill the human crew in the most slow & painful way using an inductive heating weapon. 
The Kzin hope to capture their ship intact for intelligence purposes.
 

 However, the humans use their primitive drive as a weapon, destroying the Kzin ship, and initiating the first Man-Kzin War.

A bit about the Kzin:
The Kzinti were initially introduced in Niven's story "The Warriors" (originally in Worlds of If (1966), collected in Tales of Known Space (1975)) and "The Soft Weapon" (1967), collected in Neutron Star (1968).
The Man-Kzin Wars, has so far reached fifteen volumes.
The first published in June 1988 
Kzinti also appear in Juggler of Worlds (2008) and Fate of Worlds (2012), novels.
They are extremely violent. Often described as anthropomorphic tigers.
They are larger than humans, standing around 8 feet (2.4 m) tall and weighing around 500 pounds (230 kg). 
One human gave an apt description of Kzin as "eight feet of death".  
MKW = Man Kzin War
There are 4 official wars (Wars 5 & 6 are unofficial)

Sequencing notes into a pattern. - Pioneer Toraz Squid

 There are various ways to do this.

1. Play them live.
2. Entering notes into steps (Step sequencing)
3. Use a external midi keyboard
4. Copy from scale to trigger


1. Play them live.
+ Press scale
+  Press Play
+ Press Record
+ Play the notes on the 16 pads.

2. Entering notes into steps (Step sequencing)
+ Press TRIGGER
+ each pad is a note. 
   Change the note value with the Pitch encoder on the top right.
 
3. Use a external midi keyboard
+  You can play notes live into the squid
+  you can also record notes from the keyboard into the pad.
    (trigger section)
 
 
4. Copy from scale to trigger
Find the note you want in scale section.
+ Press copy + the note you want.
+  Go to trigger section
+ Press Paste + the pad you wish to enter the note.

Voltage limiter / Clamper

 Doepfers DIY page

http://www.doepfer.de/DIY/a100_diy.htm

 

it's two low forward voltage diodes and a protection resistor.

You clamp the signal line to the rails using diodes.
Use two 5V zeners. One to +V and the other to -V.

This is a circuit that limits an incoming voltage to the range U1-UD2 ... U2+UD1. The voltage U1 has to be less than U2. UD1 and UD2 are the forward voltages of the diodes D1 and D2. To keep these voltages as small as possible Schottky diodes (e.g. BAT42) ore germanium diodes are recommended because their forward voltages are in the 0.2...0.3V range. R works as a serial protection resistor. A typical value for R is 1k.

A typical application is the limitation of an analog voltage to 0...+5V (e.g. for the inputs of Pocket Electronic or USB64). In this case U1 is connected to GND and  U2 to +5V.

Another application is sound distortion by voltage clipping. If U1 and U2 are variable voltages (e.g. outputs of operational amplifiers of one of the circuits in this document) the clipping levels can be voltage controlled too.

 

A 7805 will do a great job of limiting voltage and adding a current relator as well doesn't require too many extra components. .... +5V
