Buchla 200e explores space
Esp the later 200e series. Skylab, LEM, Aquarius, Spider, Snoopy ????
I must thank my friend Justin for enlightening me.
They are all references to NASA space exploration vehicles.
Skylab
Skylab was the United States' first space station, orbiting Earth from 1973 to 1979.
The Buchla Skylab. It's a 10U size system designed to be portable.
The Apollo Lunar Module (LM), originally designated the Lunar Excursion Module (LEM), was the lander portion of the Apollo spacecraft built for the US Apollo program
An amazing piece of engineering to say the least.
Named the LEM 208, it's a BEMI easel, minus the 218 keyboard.
Aquarius
"Houston we have a problem"
The Apollo 13 mission almost ended in disaster. An explosion on board forced the crew to circle the moon without landing. Oxygen tank No. 2 blew up, causing the No. 1 tank to also fail.
The command module's normal supply of electricity, light and water was lost, and they were about 200,000 miles from Earth. Apollo 13 "Aquarius" was used as a lifeboat. It burned up in Earth's atmosphere April 17, 1970 but saved the lives of all crew. An incredible achievement.
Below is the Buchla LEM7 Aquarius, with a 218 keyboard.
Its a great interface module ... esp for eurorack systems, providing MIDI, usb, CVs, gates etc.
The Aquarius LEM Includes:
a 3 module powered boat
225h Midi to CV converter
202u multiples & utilities module
4 half module blanks
Spider
Apollo 9 was the third manned mission in the United States Apollo space program and the first flight of the Command/Service Module (CSM) with the Lunar Module (LM, pronounced "lem"). It launched on 3rd March 1969. It was a luna module test flight. This was the first space docking of two vehicles with a crew transfer between them. The CSM was named "Gumdrop" and the LEM was named "Spider".
The Buchla LEM Spider.
The Spider LEM includes:
3 module powered boat
225h MIDI-CV interface
226h CV-MIDI interface
252e Polyphonic Rhythm Generator
Snoopy
Apollo 10 was the fourth manned mission in the United States Apollo space program, and the second (after Apollo 8) to orbit the Moon. Launched on May 18, 1969, it was the F mission: a "dress rehearsal" for the first Moon landing, testing all of the components and procedures, just short of actually landing.
As you have probably worked out my now, Snoopy was the name given to the LEM.
The Buchla LEM Snoopy
Snoopy consists of :
3 module powered boat
226h (CV to Midi converter),
225h Midi and CV interface,
292h Dual Dynamics Manager
281h Dual Function Generator
261e Complex waveform Generator
Tokyo Tower - Japan
At 332.9 metres (1,092 ft), it is the second-tallest structure in Japan. Built in 1958, Hisakichi Maeda, founder and president of Nippon Denpatō, the tower's owner and operator, originally planned for the tower to be taller than the Empire State Building, which at 381 meters was the highest structure in the world at the time.
Inspired by the Eiffel Tower in Paris, France, it is claimed the tower can withstand earthquakes with twice the intensity of the 1923 Great Kantō earthquake.

Vactrols - Optocoupliers
In the European Union, the production and distribution of Cd-based photoresistors was banned after January 1, 2010. This decision marked the beginning of the end of Excelitas vactrols. However, CoolAudio started manufacturing the VTL5C3 and Xvive is manufacturing the complete range.

Nor is not mov'd with concord of sweet sounds,
Is fit for treasons, stratagems, and spoils."

Modular On The Lounge
All my synth friends were dying for a chance to get together, chat about synths, and get some performance practice.
So we found a living room and couched it for the night.
A great turnout.
We set up a projector and a Video Synth.
Justin from Metro Modular showed us some of his new modules.
This modular just arrived back from Japan.
The MM339A Gainriding VCF
I'm especially looking forward to this filter as it's original designer was Dennis Colins who had a hand in designing the ARP 1047 filter (for the ARP system 2500).
MM6031B Marshall LPF Explorer Edition
Hopefully there will be more of these nights in the future.
