MultiStrand El Wire Jacket

My new super great source for El Wire has 'chasing El Wire' too.  I'm thinking of picking up a few strings, my biggest questions are:



  1. How do I want it sequenced? (with an 8 or 16 port sequencer)
  2. Do I want to use Chasing El?
  3. Who do I want to weave it?
    • Evens with Chasing El, Odds being 'normal El' and Sequenced?
    • The whole jacket in Chasing El plus every other loop being  'normal El' and Sequenced
    • JUST every other one being  'normal El' and Sequenced

Air Compressor - Test 2

I bought this cheap/portable Air Compressor
Its powered with 12Volts, has an operating pressure of 7 bar but can max out up to 10 (compared to my pump which is 3).

Fun Facts:

  1. It only uses 3 bar empty 20m of 5mm inner diameter tubing
  2. 20m of 5mm tubing holds around 400ml of liquid
  3. If you dont secure the output hose, the pump can spray blue dyed water over 3 meters high on the ceiling and over 6 meters across to the opposite wall

Air Compressor - Test 1

Its been a busy week ... supplies have finally started arriving (all at the same time) but another post on my newest toys soon to follow.  Included in my bag of goodies was an air compressor.  I've been playing around with using an aircompressor INSTEAD of a pump because they have much more power (10 bar instead of 3 bar/45psi for the pump).  HOWEVER, in order to use JUST an air compressor, at least part if the system would need to be pressurized and for the life of me, I can figure out how the return works.


  1. I understand how to make a pressurized source which will push the liquid through the tubes
  2. However how does fluid return?
    • In an open reservoir to release the air pressure (but how to bring the fluid from the returned reservoir back to the source reservoir)
    • If I make the source and return reservoir one in the same, wouldnt the air pressure be the same all the way around, thus water would NOT flow
    • Ive thought about pressure release valves but that will effectively lower the entire systems pressure, not just one section
ANYWAY ... until I figure out how a closed system works, I'll keep playing around with my open systems.  As it stands right now, Ill use my pump to push the water and my air compressor to push the air (and the water behind it).



So the first conclusions involving the pump vs air compressor involving 20 meters of 5mm inner (9mm outter) schlauch are:

  • Pump needs 14 seconds to fill the schlauch
  • Pump needs 50 seconds to empty the schlauch
  • Air Compressor needs 7 seconds to empty the schlauch !!!
