i was watching the list for awhile, got the bug about five years ago and built my first ccr as a class project. just bought a biopak 240 and will be converting it to an eccr. by the way the guys at meda say they will have a new dsv ready soon for about 300 us.

Welcome to the party Rick! There is a lot going on here and i am sure we can learn from each other. Is there anything you can tell us about the school project and your first Rebreather?

sven

it was a pretty simple design. can type scrubber from pvc, flat hose for the lungs, old metal reg sliced up for the adv, single stage electronics using the oopic pic to an lcd display three sensor, no housings for the electronics just potted them in casting resin. manual o2 and by way of toggle valves. al straped to an old bc. battery pods where pvc pipe glued closed and throw aways. the dsv was the hard part never did get one that i really liked and was not going to spend the money at that time on a divematics one. several of the electronics will be coming over to the new biopak 240.

changing for new unit

2 lcd displays with reed switches in casting epoxy no fancy cases,
controllers 2ea oopic s version b 31 i/o channels and 7 analog inputs per unit
new frog dsv when it comes out modified for oc bailout. anybody got a regulator suggestion
watt mizer solinoid also epoxy encapulated
depth sensor added to one controller
hud added to the other
had thought of grandure and including deco, figured that would be a good way to get bent
will be using a mag ring to trip the switches no fancy litle machining.
i have the factory aga mask for the biopak will need to make a blank to convert for the dsv
will add the wing from a prism i just ebayd does anyone know whos inflator fits it, mine is missing
plan on keep the stock harness right now but that may change

will be using nicads for this units batteries encapsulate then the charging will be done through the sensor feed wire extra conductor

eccr controller costs
lcds 50.00
pics 140.00
op amp boards 75
bits and pieces 50
batttery packs 25.00
connector for sensors 50.
sensors 210
time one weekend to build and one to redo the code
total 600 us

bio pak 240 cost 400
mask cost 140
wings 65
inflator 50
back plate 100
o2 guage 60
dsv 300
bits and pieces 100
already have the regs and tanks using 20cf mount side ways
total about 1700.00 us

but of course will pool dive as o2 unit next week before mods start.
