Philba, thanks again,

I was getting a little wary about halfway through the recent baptism by fire Several times I checked the URL to make sure I was at the right place and hadn't been redirected, to outer space!

Timing is everything! And this timing is near perfect. I am working on retrofitting some connectors on an underseas camera that is used for inspection of underwater bridge piles and cassions. The camera is expected to go to about 200 feet. The OEM camera connectors were tiny semi-rigid neoprene mold...

Hey guys ... thanks.

Now that this thread seems to have slowed down some I'll sit back and consider the opinions before I proceed. I've been stuck on basic since forever and maybe this trick pony needs a few new acts!

Thanks for the info and views...

Chris,

You've said more than a mouthful and I do think that you've been into the mixture a bit! Now, THIS is the end of this thread...

Chris I really hate to do this but here it goes: First, There is enough chest pounding about your accomplishments! I don't need to expound on the papers I may have collected, or the subjects I may have mastered. I Just address these issues with facts. You, however, have not supplied one fact to supp...

Chris, What 'history' am I accused of fighting? Where are the bags for batteries sold? Are they supplied with the batteries? In our society if a battery were to explode and someone were injured because the manufacturer did not supply, or suggest that the battery be in a bag, the lawsuit would buy al...

Regarding the plastic bag idea, well I don't think it would work. When you electrolyze water you get both hydrogen and oxygen. Check out http://en.wikipedia.org/wiki/Electrolysis_of_water for the details. If the atmospheric O2 was the problem how would it get into the top of the battery to mix with ...

Are the batteries getting hot during charge? If so there is definately a problem. Are they servicable, with caps or plugs, if not they may be dry and overheating! Normally, the battery cannot create a vacuum since there are vents for the gas. As for the storage, well that depends on the conditions. ...

BATTERY BOOM!

Modern 'maintenance free' wet cell batteries can be a time bomb! Over the past year I've seen several batteries explode with no obvious reason, but, closer investigation does indeed show what happens. As is well known, charging a wet cell battery causes an electrolyte loss as hydrogen and oxygen ga...

OK, now there are two options, PIC Basic and XCSB basic. Are there advantages /disadvantages to either(disregarding the cost)? Which of the two is the closest to the PBasic I've been using. Do either run like PBasic, program/load/run all in the same setting or are they more involved. Can I still pro...

BASIC to PIC

Over the years I've learned to do some programming with the Parallax line and now want to migrate to PIC's. I want as short a learning curve as possible since it is not a life long need! Preferrably, some of my previous designs could be ported with mnimal rewrites to a comparable PIC. I'm old school...

I might have the issue but will have to dig around. Let me know if you still need it.

Will the finished CD's be available?
