Wait It Out - Larry Niven

This story takes place in the year 1989 AD
 

This novelette is included in Niven's collections "All the Myriad Ways" 
It's setting is the planet (Planetoid) Pluto.
At the time of writing, Pluto was still classified as a planet. 
It was first published in  "The Future Unbound Program Book", 1968.
It was later published in "Tomorrow's World's", 1969.
 
The previous two novelettes written by Larry Niven concerned manned missions to Mercury & Venus. This story concerns a manned mission to Pluto that goes wrong.
 
 
 

There are 3 characters: Jerome Glass, Sammy Cross &  the narrator.
They had traveled 3.5 years to get to Pluto and are now marooned on its surface. The ship uses ion-jets to get to Pluto, but Nerva-K type atomic rockets to land. It seems that the mission is under the control of the UN.
 
The ship lands perfectly on the icy surface, but melts the ice, resulting in:

"The heat draining out of the Nerva jet had melted that ice. The rocks within the ice had sunk, and so had the landing vehicle, so that when the water froze again it was halfway up the hull. Our landing craft was sunk solid in the ice."
 
 Is there life on Pluto?
The narrator encounters a helium-amoeba alien.
It sounds much like the one on Mercury ("The Coldest Place"). 
 
" Helium 11 contaminated by complex molecules? In that case the beast had best get moving; it will need shade come sunrise. Sunside temperature on Pluto is all of 50° Absolute."


Jeremey, the first man to walk on Mars removes his helmet. 

" he looks damn good. His frost-dusted skin is indistinguishable from marble, and his eyes are lifted toward the stars in poignant yearning."

Buchla 237 - Keyboard

 The Buchla 237 is a rare keyboard.
 

Don Buchla preferred touch controllers like the 218 & 222e, 223e etc
 
 

 



The thunder 223e









 
 
 
Its usually seen accompanying the 212 - Dodecamodule
 Don produced a few system 101s that combined a 237, 212 & 258 (VCO).
 
 
I understand that these keyboards first appeared around 1971.
The 237 & 238  keyboards which were created were I understand, the first polyphonic modular controller keyboards ever. (Do let me know if I'm mistaken)


The 237 was one of the very few conventional keyboards that Don invented. Though he studied piano
Don wanted to free musicians from traditional Western music.


“A keyboard is dictatorial,” he said. “When you’ve got a black-and-white keyboard, it’s hard to play anything but keyboard music.”


The 237 keyboard is amazing however if you consider that it was made in the very early 1970s.
 
 
This is arguably the world's first modular polyphonic keyboard. It has four CV outs and gates.

Reese Baselines - Abelton - using Analog, Operator & Wavetable synths

 Reese Baselines can be made with virtually any subtractive synth.
It's that low grungy rumbling sound that you will have heard a million times.
The synth can be analog or digital.
The original name comes from  Kevin “Reese” Saunderson.
In 1988 he released the classic "just another chance"
 
 
This was the first documented recording of what history from then on named a "Reese Bassline" .
Though it started off in House music it's often associated with DnB, Dubstep.

There are lots of ways to do this and its really down to personal taste what you finally come up with.
It’s basically  two or more detuned saw/triangle/pulse waves that battle.
Because they are slightly out of phase they undergo phase cancellation with one another. 

----------------------------------------------------------------------
 

Using Abelton's Analog Synth
1.load up a saw wave on oscillator 1, and a pulse or saw wave on 2. 
2. Detune each oscillator.
3. Add a lowpass filter, and  play with the resonance. 
4. Add distortion./ another filter... Notch ??
 

Here are the abelton files
 
---------------------
Using Abelton's Operator Synth
 
 

1. Switch to the last algorithm mode
2.  Set voices to 3-6
3. Oscillator A to SAW D (SwD)
4. Oscillator B to Saw D
5. Set both VCOs to 12dB and detune Osc B by 25 (fine adjustment)



7.  Add a pitch envelope
     Turn on Glide. Adjust time 
8. add a Filter. Use this to reduce the highs.
9.  I like 24 db, 4 pole filter MS2 mode.
     Add Resonance to 53 about
10 Add EQ Eight
11. Add saturation

You can download the Als file here:


--------------------------------------------
Using Abelton's Wavetable Synth
 

 
Like the two examples above we need 2 oscillators
The Abelton Wavetable synth has just this ... 2 oscillators
 
Osc 1
 

 

Turn off SUB 
Set Oct to zero
Set Oscillator 1 to 100%
Set Osc to classic
& use Basic Shapes 
(Square or Saw)
PW=66%

Osc 2
use Basic Shapes 
(Square or Saw)
PW=66%
 
Remember to detune each slightly.
 
Or you can set it to a FM synth for a bit of crazyness.
 

I like to add something like a notch filter and distortion at the end of the chain.

The abelton file is here:

Known Space - Larry Niven - Part 3 - Years 2351 - 2650 AD (including the The Man - Kzin Wars)

 

Tales of Known Space - Larry Niven - Reading order 

 
This is part 3 of  a suggested reading order for Larry Niven's novels set in Known Space.
Parts 1 & 2 covering the Belter & Slower Than Light Stories are here.
There are about 9 novels and 35 short stories set in this universe spanning  over 1000 years in the future. The region covers a small portion of the Milky way.
Beginning with the first human explorations of the solar system, the later stories describe humanity's expansion into other near systems.
 
You can probably divide this time span into 4 periods:
1.  Early Exploration (Pre 2000 AD)
2.  Slower-Than-Light (2000 to 2350AD)
3.  Years 2351 - 2650 AD (including the The Man - Kzin Wars)
 
This page covers the 3rd part -- Years 2351 - 2650 AD (including the The Man - Kzin Wars)
Space travel still uses the slower than light ramscoop starships which travel very close to lightspeed in the early books, though later, hyperdrives are introduced, paving the way for the Faster-Than-Light (2651 AD and later) period.

Niven later joined the slower/faster than light periods into a single universe in the short story "A Relic of the Empire" (If, December 1966). Then in the 1980's he started writing stories of the Man-Kzin Wars. The first volume was published in 1988. This filled in the 300 year gap (between 2350 to 2651).

---------------------------------------

Years 2351 - 2650 AD (including the The Man - Kzin Wars)


I think Neutron Star is a great place to begin exploring this period.
It was first published in April 1968.
Ballantine Books.
All stories are set in Niven's Known Space universe
between the years 2350 to 2658 AD 
This collection features the following eight stories:

 

The individual stories were published in If and Galaxy Science Fiction in 1966–1967, 
under Frederik Pohl as editor.  
 
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".

Deluge Synthstrom - Single Cycle Waveforms


The Deluge synth can use SCWF (Single Cycle Waveforms) to create unusual oscillators.
Audio files less than 20ms are perfect.(but it can use waveforms that are longer)
The preferred format is:44.1kHz 16/24bit.WAV or AIFF up to 32bit 96kHz.
You can make these using Audacity.

Steps to load a SCWF into the Oscillator section
There are 2 ways I've found to load these:

Method 1 (short way)
1. Be in Clip/track view
2. Shift + Browse (this loads the first osc to the browser.
3.  ‘bot-toP’ will scroll on the display to
       indicate the bottom-to-top note range.
4.  Press the select button
5. scroll to your SCWF folder
6. to change the SCWF , just press the Select knob again
7. use the audition pads to play.
 

Method 2 (long way)
1. Press the Clip/track button
2. Press the Synth button
3. Shift + Type (grid button) ...
4. Press select twice... you will see OSC 1 displayed
5. press select again ...you will see type displayed
6 Press select
7. Turn select to find "SAMP". (Sample)
6. Select a sample. Navigate to ‘FiLE’
7. Press select.
8.  ‘bot-toP’ will scroll on the display to
       indicate the bottom-to-top note range.
9. press select. navigate to your SCWF folder


To enter the Waveform view
1. Shift + Start
   You should see the waveform with start and end points.
2. You can play it by pressing the Audition Keys.
3. Start = Green
    END = Red
4. Pressing each will cause it to start flashing. You can move the start and end points.
5. You can zoom in using the left/right knob (hold down & turn) to increase the resolution.

Setting the start and end loop points.
1. Hold the start line with one finger and touch the new loop point with another finger
2. Do the same for the end point
3. Start = blue
     end = purple
4. You can zoom in using the left/right knob (hold down & turn) to increase the resolution.

Power Supply - NLC - Build notes

Building a Nonlinearcircuits PSU.
This just supplies +/- 12V for Eurorack modulars.

Andrew's build notes are here:
http://www.sdiy.org/pinky/data/WAMOD3%20%20psu.pdf


The virgin PCBs

 Ok, lets twerk
Keeping Miley happy.

The PCB receives 12VAC from a plugpack/ wallwart
. The 1N4004 diodes split this into positive and negative waveforms.
 
The 4700uF capacitors then smooth out these waves
. The 7812 and 7912 regulators then convert the rectified & smoothed
signals to +12V DC and -12V DC and these are fed to the connectors to be distributed to your lovely modules.
I'm using 250v TDK film caps for the four small 100nf caps
Probably a bit overkill, but it's what i had in stock at the time.


Some pics of the 7812 & L7912 voltage regulators attached to various heatsinks.


 In the NLC build notes, Andrew stresses the importance of isolating the regulators from the heat sinks.

The smaller heatsinks came with grommets and mica insulators, so I think I'll use those.
He also recommended using heatsink paste.

Andrew F recommended I use these - http://www.taydaelectronics.com/capacitors/electrolytic-capacitors/4700uf-50v-105c-radial-electrolytic-capacitor-19x40mm.html

25V caps are okay but better to get 35V or 50V rating. just to keep the action well clear of the edge.

Always bigger is better with heatsinks, smaller ones cant soak off so much heat so will limit the current output of the regs. With a small one you will only get 3-400mA, a big one will get you double that (roughly...very)

The other thing to watch is the proximity of the heatsinks to the caps.
They do appear to be pretty close in the pics.
My sinks don't appear to get hot but they could cause problems if the temp exceeds the cap ratings.
These caps have a rating of 105 degrees celsius.

------------------
This PSU also has space for a 78L05 regulator.
Most of these are rated at 100mA

However, a standard LM7805 can be as high as 1A
A LM7805 might be a good substitution
If you are substituting remember:

1. the pinout is different so the 7805 goes in backwards

2. the 7805 can suck a lot more current than the 78L05 (10x more) and can take as much as the 7812, so keep it in mind and dont try to overwork it.


No need to change caps.

I'm using 1K resistors for the LEDs
