Hi guys!

I have been thinking about version 8 and I have realized the follwing:

1. I will keep The Hunchback as an MCCR. I have noo need for an ECCR, sure it would have been fun and all, but hey! It works as an MCCR and I have less hassle with solenoid placement and hoses etc. It will just make it all much easier and leaner. Less is more!

2. I will go back to my original placement of bottles. O2 on the left side and diluent on the right side, to keep the hoses as short and neat as possible. The bottles gives good balance to the rig and makes diving easier in many ways. It allows for neat hose placement!

That´s it! Took a while to make up my mind! ;=) Back to the dive garage!

 Have a great weekend folks!

My new rebreather electronics has arrived. I have tried Shearwater electronics for a while, but I have now decided to change electronic supplier.I have now changed to Hammerhead electronics. It looks very nice and I have followed Kevins progress for years now. Well, it was about time for me to give in to his electronic solution for rebreathers, Hammerhead. All I can say is that their sales support has been excellent! It sure looks nice! I will post pictures soon when the work begins to include it into the loop. I still have to find a good solution on how to integrate the solenoid in a safe and efficient way in the canister head.

I have added a couple of nice B/W pictures of version 8 with the BMCL´s! Have a great week!

Hi friends of the Hunchback!

During christmas an RB concept idea had grown on me, I wanted to build back mounted counterlungs, BMCL, for my hunchback! I was tired of having bags on my chest! ;=)

I looked on the several projects of Dave Thompson and read his postings on RB forum for inspiration.... no pun intended.... ;=) and suddenly I realized that the solution was right in front of my nose!

I bought a secondhand BCD for inspiration (due to its size and price), opened it, gutted it and thereafter I put two MSR bags in. These bags can be "molded" into whatever size I want with the help of a simple household iron, read an earlier post. The result speaks for itself! It passes postive and negaitve tests with flying colours. Now if I could only get it to a lab where there is a ANSTI test machine so I could test its breathing resistance then I would be a very happy man....Anyone care to help me???? You can reach me through RB forum, send me a message!

Somethings are missing right now that will be added during the spring:

• O2 addition, manual bypass
• Solenoid, ECCR concept as a parachute
• A hub for all the hoses
• A smal ADV on one of the T-junctions on the back
• Shorter hoses for the back end 
• Spare PO2 display 

Hi friends of the Hunchback rebreather project!

As you can notice I am back to the rebreather table designing and creating a new version of the Hunchback! My motto for this version is "Less is more!”. I will strip away anything that is not deemed necessary to the Hunchback Rebreather version 8.0! Follow my project next year on these pages! I think you will learn to love version 8! I love it already! Take care friends and have a merry Christmas and a happy new year!

I finished version 7 this summer and dove with it for some time and tested it under typical scandinavian field conditions! Since then I have taken a time out from diving due to many things that has happend in my life lately. However, it is time to move on with my life and the best way to do so is to focus on a new rebreather version. It is time to build version 8 of the "Hunchback"! It is going to be a brand new design and the Hunchback will take the last step on its CCR evolution ladder, it is time to become a full blown ECCR! Watch this blog for updates during January 2010! Have a nice Christmas! See You on the other side next year!

I tried a method today to create a customized counterlung. I have used the MRS bags for a long time now and fellow diver in Sweden gave me a good tip that he had found on rebreatherworld. This is how you do it. Take a dromedary lite bag, preheat an iron to the maxiumum heat and firmly press the iron on to the surface that you want to melt for about 30 seconds then quickly remove the iron. This will now have created a perfect seal. You can now customize the MSR bag as you want to. This is great news, at least for me!
