    O-Rings for Oceanic Computers

    I *believe* that the B.U.D. O-ring is the same as the ATOM 3.0/3.1, which I also *believe* is 1.2mm x 27.5mm.

    Importing Oceanlog into Subsurface

    I'm not sure what the format is of the exported Ocenlog data, but I have attached a sample of a dive in subsurface's XML format. I expect that with a little sed, awk, perl, or python -fu you should be able to translate the Oceanlog data into this xml format. From that, subsurface should be...

    Oceanic Atom 3.1 or OCi

    I have an Atom 3.0 (actually, I got two, one for my son as well). Although I don't have a great amount of experience, I generally like the Atom pretty much. I had been concerned about seeing the display (55 year old eyes, nearsighted, but with contacts..) but it hasn't been a problem in...

    Lets make DIVE ATLAS - USA

    The type of info you are wanting to collect sounds so much like climbing sites around the country to me.. Look at Mountain Project | Rock Climbing and see if the data collection and organization would be a decent fit for scuba dives.. They've been at it for 10 years and have 134,698 routes in...

    Underwater Camera Recommendations?

    On the inexpensive end of things, the Canon D30 is 12MP, shoots 1080p video, and goes down to 80' (it will *probably* make it to 100' safely), so it comes close but doesn't meet all of the requirements, but it can be had for $250 (it's about $300 now, but I purchased it for $250 in June). Not...

    D9 Transmitter, Battery Polarity Reversed

    Do we know that the OP's transmitter is dead now? Chicken SCUBA said that he did the same thing with no ill effects. There are two primary ways to go about protection, a forward biased diode in series with the battery, which lowers the voltage by the forward drop (1.2V for most diodes, but I...

    Atom 3.1 or O

    My son and I have been using the Atom 3.0 for a year now.. I got a good deal on them, about $600 each with transmitter. Although we have about 20 dives on them, we did replace the batteries in each. I think that they were sitting on the shelf for several years, so it doesn't seem...

    Devil’s Lake fatality - Wisconsin

    Just visiting Devil's Lake today from Colorado.. (But for rock climbing, not diving). All of the reports I've seen sound like diving alone. I can't imagine any kind of buddy just leaving. Sad report.

    Dive shop recommendation in upper or middle keys for infrequent/newer diver

    Second the recommendation for Rainbow Reef. My son and I got AOW certified and spent three more days diving with them earlier this year. We really enjoyed the trip and always felt very well taken care of. Everyone was very helpful and made sure that we had whatever we needed every trip...

    VT4 O-Rings

    That's what I had thought at first, but was convinced otherwise. 1/16" is 1.58 mm, so it would require quite a lot of stretch to thin it down to 1.2mm. I hope that new designs use common AS o-rings, but I am now convinced that the Atom 3 at least is metric, and a non-standard metric at that.

    DIY Gas analyzer

    Are there any 3d print plans for a housing available? I have no experience with 3d printing yet, but it doesn't seem like it would be too complicated. An arduino nano would certainly be capable of running this. You just need an analog input for the sensor, maybe a reference input as well, a...

    VT4 O-Rings

    Of course, it is entirely possible that it is metric sized.. The Atom 3.1 computer O-ring is 1.2mm cross section and appears to be 27.5mm diameter. I haven't found a source for that size, but 26mm diameter is available. Perhaps this is the size and it gets stretched.. I'll likely buy an...

    O2 + CO analyzer choices.

    OK, so probably not too far off, but sub-optimal.. 1% error certainly isn't significant in itself, but if too many of them start adding up all the same way, it can get to be significant.. This was originally in the context of calibrating the unit with my phone, then leaving the phone in the...

    O2 + CO analyzer choices.

    Of course, you could easily do it with two buttons.. (There is an existance proof..) Alternately, you could do something like long press takes you to calibration, or to a menu where short press advances and long press selects.. Might not be too awkward so long as it's reasonably simple. Is...

    O2 + CO analyzer choices.

    I just wish that it could do calibration without requiring the smart phone present. It seems that it will report all of the readings and log things entirely by itself, but calibration requires assistance from the smartphone. I'd prefer to leave my phone on shore and this requiremet for...

    Looking for Dive Buddy for Devil's Lake Barabo, Wi July 11 3025

    I know on all of the old maps there was mention of potentially finding old wine bottles where a winery apparently used to be just off of the south shore beach, but that was supposed to have been picked over thoroughly years ago. There used to be a dive shop in the area, but it closed some time...

    Changed depth limit for PADI Open Water

    My son in 14 years old, and just got "Junior Advanced Open Water" certified. We were discussing why the 70' limit, and I suggested that it was likely to stay well away from possible narcosis situations and a still developing brain. (Well, presumably developing..) If the 60' OW limit is not...

    Dive light from E-Bay -- Great buy!!!

    I measured the o-rings that came with my light as N2.0x21mm front and N2.0x22mm rear (one of the front o-rings was actually 1.3 x 24mm, but I think that wasn't really the right size). The channels are 27mm and 28mm diameter, so I have also ordered 2.0x26 and 2.0x27 sizes, since I think that a...

    Dive light from E-Bay -- Great buy!!!

    Well, I haven't received them yet, but I have ordered replacements from "the o-ring store" www . theoringstore . com . They have a wide choice of o-rings, including metric sizes. Minimum order for most o-rings is 4 or 5, and shipping is $5 for small orders. I measured the o-rings that came...

    DC1400 resists firmware upgrade

    Well, I hate to say it but it appears that linux has let me down on this one. with the SD card mounted as a vfat filesystem, it appears that the filename is not in the right form for the camera to recognize. I found a windows system and wrote the file to the same SD card with that and the...
