As we're waiting for our factory trip on Monday we're looking into getting conductive rubber electrodes like these created in China. They could be a good alternative to our steel electrodes for people not wanting to make a hole in their CB6000. The cables would probably have to be thinner to attach a connector...
Waiting for 100 tiny parts from Korea related to this hard to manufacture "Surprise" feature. Once they get here we have Jason's authorization to go to the factory and stay at the machine with a technician for as long as it takes to get this to work! That's really VIP treatment!!
The parts should have arrived today. Unfortunately EMS tracking says the package is being held captive at customs. So we're trying to resolve this issue.
Once we get the parts we'll take the 1 hour bus again and head over to the factory through endless fields and broken down buildings, and let's hope they don't stop mid-way to fill it up with 300 liters of gas because it took 30 mins the first time.
There are a few parameters we'll be able to play with.
They're nowhere as complete as PHPBB but hopefully this will deter spam, captcha hackers, automated bots! Please see "Forums top" (top menu on this page).
We'll be adding categories and functions as time permits!
Some breakthroughs with waterproofing after we posted the last entry...
1) It seems the O-rings are all ever so slightly different in size. Perhaps this is because they have to be pulled out of the mold and they get deformed when this happens. So we found the best sized O-ring out of the bag of samples and tried that. Immediately the quantity of water leaked was reduced. We need to verify with the manufacturer why there is a size discrepancy and fix it.
2) To better test the O-ring we replaced some "filled" grommets (without holes) to the real grommets so that the O-ring and screw rings would be the only parts which could leak. We're 100% sure the screw rings do not leak. Therefore we are singling out the O-ring for testing.
3) The bottom of the enclosure has screw holes that are too small, and for this reason the screw has to tap its way in rather than just sliding in effortlessly. This has the side effect that as the screw comes out of the bottom and enters the top of the enclosure, the grooves created in the top are misaligned if the halves aren't pushed together with great strength...
Here are the new enclosures. They are made in China so the finish quality is much lower than the previous ones from Korea. Notice how nicely the rubber attachment fits with the plastic part, using four small screws (black, same as the final rubber color) and how the logo emerges through the rubber (this will be more evident when the colors aren't white and white).
