Your post is jam-packed with amazingly great points. Thank you for taking the time to respond. Genesis is now at the top of my list.

I came here for the headline because I searched "Genesis 3.1 vs. Cuda X". I'm assuming by the messages that Genesis won the Navy contract. The problem is that you can't trust a government contract as any indication of quality. Maybe back in the day, but not now. Most contracts are LPTA...

No HE sensor. You use another o2 sensor. You calculate the displacement of o2 with helium. So if first mixing chamber sensor reads 10.5, you have 50% helium. Then you add o2 back in the 2nd mixing chamber. At least that is what I have been told. It has been a long time since I took the blending...

$4500 for the base model. Whatever that is.

This can be done rather simply. You would need a larger valve than the one that I listed on my GitHub page. Something more along the lines of the link below. The algorithms should still work. They may need to be tuned a bit differently though. My little mini valve tops out at 40 l/m...

I have considered this. I have the solenoid valve, and a current transducer for it, but never got around to implementing it. Being that I started this project with the desire to get something working for my own system which only gets a few hours of run time monthly, I never really got around...

Thank you. I will look into this. These kinds of pointers are exactly what I was hoping to receive by posting the project online. I really appreciate it.

One safety is to set the setpoint to 40 and dial back the o2 regulator to a max of 1-2 PSI above what you are really wanting (eg. 34% for a 32% mix). Then change your setpoint to what you really want. This will provide an upper bound if the proportional control valve gets stuck open. One nice...

I mean it works, but I'm just a very part engineer/developer. The days of doing this kind of work are behind me. I accept that my coding may not be up to snuff when compared to many people much better at it than me.

?

Someone recommended I post this here. This is a work in progress, but a fun project. I have created a nitrox blending solution using a Arduino microcontroller, and a proportional control valve. The Arduino has a PID algorithm coded into it that will allow the user to set a specific setpoint...

I am assuming this is sold. It has been a while.

Does it have the shearwater or HH electronics?

Let me think about this. It would probably make an easier sale. Im surprised no one bought yours for $1000. A couple questions though. Do you have a link or more info? Has the solenoid been upgraded to the new one? I ask because the new one is 85 psi vs the old one at 140psi. Thanks. Jeremy

Selling BMCL conversion for Choptima. This includes everything you need to convert your O2ptima CM to a BMCL configuration allowing you to have 2 units with only swapping the head assembly. Can possibly deliver along rt95 between Baltimore, and Cave Country. $3000. Any questions please ask...

Are you making these? Who is retapping the threads?

DM Sent.

Let's see if I can get some traction on this. I got a new suit and this one will collect dust. $1000 shipped to the US. Includes SiTech oval replaceable seals, dry bag, talc, and tools for replacing seals. If you want the dry glove system add $75.

Shipping in the US is included and local pickup is perfectly fine. I’m in Pasadena, Maryland. Suit and dry glove system was over $2000 new. I’m asking $1500 (ish). Make me a fair offer I may take it. Drysuit for sale. It is in great condition. I originally purchased this from diverightinscuba...

Thank you for reminding me. I was looking for a close thread option but didn't consider the title.
