Hi there!

 

Well things never remain the same nowdays, do they? :=)

 

My friend Stefan, who is helping me with the cable and the housing for the electronics, found a weakness in our RB design while pressure testing the housing & cable solution. The cable is not airtight which means that if water comes into the cable it will be able to run down to the housing and/or into the canister. Well, this was a major headache for me since we can not accept that risk. How could we solve this problem?

 

I spent a sleepless night in bed thinking about this problem and how to eliminate the risk, and I found a solution. The solution meant a higher cost for the project, but we had to accept the cost compared to the alternative.

 

 

We decided to install fisher connectors on the cables and the on the recieving ends. For those of you who don´t know what the company does for a living, well surf to their website and find out more: http://www.fischerconnectors.com

We will try their cable solutions and their patented  locking system:

 

After a one hour discussion on the phone with the sales rep. of fischerconnectors in Sweden and many hours of thinking, we decided on the following solution:

 

1. For the canister part: DBEE 103 A 051-130 E

2. For the cable: SS 103 A 051-130

3. Protective caps feedthrough: 103.2273

4. Protective caps cable plug: 103.2274

The protective caps are for when the unit is being transported to protect the connectors.

 

This solution will also add the extra security for the electronics during transport. Now you will be able to loosen the handsets from the rebreather and transport them safely in a pelican box until it is time to rig the unit before a dive. It makes the transport just a bit more simple and adds transport security to the solution. It also means that you can change the handsets on the fly. Let us assume that one handset is destroyed for a any reason (it can happen even to the best of things) you just unplugg the destroyed unit and plugg in a back-up unit with the same cable configuration in less than 10 seconds and your passive electronics is up and running again! Or if you happen to be rich guy/gal and have spent money on a VR3, well just plugg it in and run it off any sensor inside the canister (there is room for up to 8 sensors in our solution!!!!!) Now that is a flexible rebreather solution!

 

Stay tuned in for more news on the project!

Hi there folks!

 

This week we have been working on the new canister. We have fixed the O2 addition port, as you can se on the pictures, and it is standard metric thread, 12x1. No strange UNF, BNC, etc. We have decided that all threads on the canister follows the metric system. The only tool you will ever need for the canister is a small screwdriver. We have also been working on the housing for the electronics and they are as we write beeing tested down to 70 meters for any leaks. The art of making stuff waterproof is delicate and underestimated. Keep in touch and stay tuned in to the hunchback pages for more stuff soon!
