But you've said that trip reports (or content from trip reports) is already being cross posted to Instagram, right? Are/were the originators of the trip report content aware that it has been / will be published to Instagram? Do/did they consent? Is there a clearly visible method to opt in or...

I tried to do what you suggest. Clicking "Cast Vote" with none selected just causes an error message that says in part "vote for at least one option." So in fact it is impossible to indicate "none". Ok, so there is no social media called "none", but why take the comments here so literally...

I think you can expect the dive operator to accomodate your need for a weight check to get you into the ballpark, maybe a few pounds heavy, and in my experience they'll do so willingly. Depending on conditions (weather, group size, experience, dive site etc. etc.) they will want to choose...

Another good tip, thanks. @chillyinCanada, just noticed that the posts in a thread are actually numbered! Glad you figured out what I meant anyway. Maybe I'm finally getting to know how to use ScubaBoard...

I still haven't got my transmitter into the same room as my computer to try recording with the sound card, but I have verified that even though the card samples up to 192 ksps, the frequency response drops off beyond 22 kHz (down -1.7 dB at 22 kHz, -9.0 dB at 23 kHz, -24 dB at 24 kHz and...

@chillyinCanada, I went and deleted it after I saw your earlier message. I've also figured out how the image got there in the first place because I've just done it again by accident. After quoting part of a post, I've been pasting to include the quote (which pastes whatever was on my...

Good to know (lucky I haven't said anything I regret yet...).

Ok - I saw the big delete button but it looks to me like a button to delete the post, which is why I avoided it. Thanks for the help. uwe

Sorry. It the second post on page 8 (the last page. There are a bunch of quotes and the attached image is at the bottom.

No new data yet. @Pkishino, good idea, but right now I don't know an easy way. It would be dead easy for anyone with a storage scope or logic analyser, but that's probably not a whole lot of folks. @dm9876, it doesn't seem to be literally the NEC code, but just using the low-level bit...

Thanks @chillyinCanada. This post: Reading Wireless Air Transmitter using Arduino When I edit the post, their is no text corresponding to the attached image; it just shows up below the edit box, and the image shows up at the bottom of the post.

Hi, I can't figure out how to remove an image file that I accidentally attached to a post. When I go to edit the post, I can see how to do just about everything else, but not that. Is the big delete button at the bottom right to delete the attached file? It looks to me like a button to delete...

What I see at the beginning is 0010000001101... or 1101111110010 ... depending on whether it's literally NEC bit-coding or the inverse. I have two transmitters and this part is the same for both, so maybe there's a constant header, or preamble, or manufacturer id. I can't get a clear enough...

Good idea. My first thought was that it wouldn't work without an analog front-end to amplify the signal and filter power line noise (I see a lot of that on my scope, but it has good filtering to eliminate it). My second thought was that higher sample rates on sound cards are meant for better...

I like this idea. I was setting up my shop compressor when I remembered this thread, so I decided to hook up my transmitter and take a look at the output on my scope. I don't have a tank handy. I don't think it's FSK, PSK, or anything that sophisticated. What I see looks exactly like CW...

As a curtesy to others, would you please mark the post sold, so we don't end up at the end of the comments before we find out? Cheers

Two more things: I'd carefully consider all my requirements now but not make the final buy until I really had to have it: maybe there'll be a shiny new model by then, and I'd want my "old" perdix to be my backup. Max depth of the peregrine is "only" 120m, while the perdix, teric, etc. are all...

The hotline is available to anyone anywhere anytime. You don't need to be a DAN member, or buy insurance through them to use it. I know, I used it once (and argued with the Dr. on the line for about half an hour before he finally convinced me over the growing ringing in my ears to visit the...

My mistake, I guess the PADI course has modified focus since first introduced, and I hadn't bothered to update. Back then I was told explicitly "it's not a solo cert. It's to become a safer diver through self-reliance, not a solo diver, which is unsafe." I see the PADI course description now...

#deepfix: check out "Scuba Regulator Savvy" by Pete Wolfinger. Not just a how-to, but detailed explanations of the theory and specifics of regulator operation, with LOTS of diagrams. It is quite wordy and sometimes repetitive, but if you work through the content you'll either feel confident...
