1010 bitbox - triggered by Pioneer squid

 Some notes for using the Poineer's Squid with a mark 1, 1010 Bitbox

The Bitbox has 16  cells to trigger.
Exactly the same format as the Squid
 

 
Set all the trigger cells on the squid to output from midi 1, channel 1. 
 


These notes are good for a Squid

Befaco - Percall - build notes

Some personal notes to build the Befaco Percall.
Its a euro module.

I purchased a complete kit. Has all the parts and a printed BOM, instructions, etc
looks great. Everything is through hole.


ic Headers first


100K rEsistors next
They are small 1/8 watt


Diodes next




Capacitors -- 104 - 100nF

There are 24 of these
101 - 100pF
 


Transistors


 iNsert ICs

 

I made the mistake of placing some of the headers that join the two boards on the wrong side of the PCB.

THE HEADERS ON THE LEFT PCB ARE ON THE WRONG SIDE.

Ed of Elk Elektroniks  helped me correct this error.

Put the jacks on the top PCB but only solder when the panel is firmly on.







 tHIS is what the rear of the module looks like.



All the components should face one another. It's a tight squeeze.

Sci Fi Index

 Sci Fi
 
My sci fi index. 
 
The world of Science Fiction is very important to me.
What is sci-fi ??
Is it space opera ? or Marvel ? Must it be "Hard Sci-fi" to be any good?
No, no, No.

I think that the answer lies in the words: Science & Fiction.
Science is full of facts, reason & logic
Fiction is full of ... well fiction ... stories & myths.
The two words are like the opposite poles of a magnet.
They shouldn't be able to exist together.
Yet they can.
This clash is what makes Sci-fi so powerful.
Sci-fi unifies the two worlds into something new and powerful.

Synthesizers and Sci-Fi go hand in hand. 
Electronic music is about Futurism. 
Synths and drum machines represent a new future where science and technology 
hold the promise of a better world.

From special effects, to movie soundtracks they feed off each other. 
I owe programs such as "Dr Who" and movies like "Star Wars", “Forbidden Planet” and “The Day The Earth Stood Still” a great debt for introducing me to electronic sounds and music. Those early films and programs were enhanced by those synths and they in turn paved the way for commercial artists like David Bowie and Pink Floyd to expose the masses to electronic music.

 I'll update this post over time. .. The link can be found in the index to the right.

Greyscale Algorhythm - pics

Some build pics
This is a super easy build. Recommended for a beginner.

I purchased a complete kit.

aLL the tricky surface mount components are already installed.


The Algorythm is gate sequencer in a very small size. There are smaller gate sequencers, but they tend to loose the visual ability to easily see your sequence as it plays. My fave gate sequencer is the Tip top circadian rhythm, but its very big. You can see the leds light as the sequencer runs. I feel this is a compact version of it.
 
 



 40 pin header first

 

 Jacks next
WQP-PJ3410 jacks with round nut


LED switches next



LED switch (white) PB61303-BL5 (momentary) 4
LED switch (green) PB61303-BL6 (momentary) 8

The top 4 white switches first -- Sw1 to SW4


The lower 8 (green) switches
The red mark is -ve




I found that is the space between the two PCBs was too small, shorting can occur.

So make sure the gap is there.
