808 Key Chain Cam - How fit a wide angle lense plus lense comparison video #11 #16 #3 etc.

[josephbilling]

This is a great video! I plan to order this cam soon and thanks to you I know exactly which lenses to order and how to fit them. Top notch!

[bobflyman]

@josephbilling No problem mate. Have fun.

[TheSliekaStyle]

Nice idea! Keep it up!

Where can get that magnetic ring?

[bobflyman]

@TheSliekaStyle Two sticky rings are supplied when you buy the lense.

[Nriku8]

I'm interesed in aplying your fantastic tutorial on my 808 jumbo #11, and I don't know which one did you used. Sku 39814 or 102101?. Thanks. Another thing, did you managed to do a holder for motorcycle?

[bobflyman]

@Nriku8 I use DealExtreme Universal 13mm Wide-Angle/0.67X Macro Lens Attachment for Digital Cameras and Cell Phones 14953 and 15mm Detachable 180-Degree Wide Angle Fish Eye Lens for Cell Phones and Compact Digital Cameras 39814 For paragliding I have a small plastic bracket that fits in the chinguard of my full face helmet.

[alexinshade]

December 2012 yeah :)

I've got me lens off ebay, seller's name fofofovs. I don't like the DX of late...

This is after trying a plastic version. The whole thing is of course inspired by your videos :)

Well, I've got the lens and now I'm about to apply it to my jumbo cam. I have a question though. At 1:00 as you're saying "this is a band new one" I think there is a modification to the view hole in the case it's kinda beveled. Is it important thing to do?

[bobflyman]

@alexinshade I found that you can get some reflections from the inside edge of the hole in front of the lense so I bevelled the edge. It works. Best way is to remove the inards (don't touch the circuit board , hold by the edges) and use a small twist drill by hand. You can do it wil a scalpel blade alternatively. I wouldn't bother unless you have a problem. Have fun with the lense.

[TheJiggz043]

@alexinshade when you got your fish eye , how long did it take and how goo are they cuz i bought them yesterday :) please reply



[alexinshade]

@TheJiggz043 it took them 12 days to arrive.. I think they are as good as they get considering the size and overall DIY approach.

[clarebannerman]

2 Tips: (1)To get rid of those black stripes at both sides of your video, just go to edit video and down at the end under tags add this tag  yt:stretch=16:9 (and save of course)

(2) To record on macro mode just place a hand held magnifying glass over the lens...

[bobflyman]

@clarebannerman Thanks for tips. I have seen the codes mentioned. The video was made with an SD camcorder so is 640 x 480. Interestingly I tried the tag but it had no effect on the review part of the clip. The test clips do present as wide full screen. I've played with a few big lenses and magnifiers in front of the lense. Interestting results.

[clarebannerman]

@bobflyman I'm referring to a video on YT "How To Fix Aspect Ratio on already uploaded videos."....may be of use. Thanks again for all the tips. I use a Flip Camcorder myself..but I have ordered a 808#16 . Someday all camcorders will be this small...so handy.

[bobflyman]

@clarebannerman Useful . Thanks. Have fun.

[clarebannerman]

Thank you very much...very helpful video.

[bobflyman]

@clarebannerman No worries.

[bored1980]

Excellent video, thanks. Can I politely suggest buying a cheap €20 tripod? I just bought a 808 #16 camera a few minutes ago and I like the idea of a fish-eye lens for use as a dashboard camera. Thanks again for a very helpful video.

[bobflyman]

@bored1980 I take your point. I have two or three mini tripods from suction cup types to 3 legged but not one one that's big enough for an overall view. It does add a certain touch of immediateness doing it without!

[justinspirational]

Also-my main purpose of this cam is for rc  flight videos-even with the ring epoxied to the cam, my concern is about the lens itself falling off in flight with the g forces involved as the strength of the magnet is pretty weak-any tips on more securely attaching the lens to the ring, without making it a 'permanent' attachment? Thanks again

[bobflyman]

@justinspirational Not sure what to suggest apart from maybe a string to attach is and maybe blue tack or something? I've made a tube with glass in the end to secure it if I use it suspended in the canopy paragliding. Didn't have any probs with it falling off when I flew it on my leccy glider, but it's pretty gentle flight I guess.

[justinspirational]

@bobflyman do any of your videos show the glass tube you speak of? someone else suggested 'hot' gluing the lens to the ring as it's easier to remove than CA or epoxy

[bobflyman]

@justinspirational I made it really as an underwater housing, not very suitable for rc models (apart frpm big ones maybe.) I plan to use it suspended from my paraglider and it will prevent the lense from being dislodged when I launch. At 5 m 32 s in this video 'HD Key chain and 808 key chain mini dv on Orion glider and underwater housing

[justinspirational]

@bobflyman thank you

[justinspirational]

Thanks for your video-I have the #11 camera and the deal extreme fish eye lens however you can see the edges of the fish eye legs in the corners of the video (see my snow boarding video on my channel)-will shaving away the top, like you did, help with this or anything else? Thank you

[bobflyman]

I had the same problem It's caused by the lense not being in the perfectly same plane as the camera lense. I experimented with it in web cam mode and figured it needed a little angle to it .sorted it after a lot of experimentation and refixing the metal ring different angle. check out my latest 'Video test - HD Key Cam 808 mini DV type 16# with V 18 firmware ' at 1m 24 secs you can see I have virtually elimated it. Fisheye test with 11# paragliding at Freathy has same probs

[justinspirational]

@bobflyman thank you- it seems the fish eye lens edges show more than the wide angle lens edges in your test footage (the latter lens doesn't seem to show its edges at all)

[skotch40]

Thanks for the great video!

[bobflyman]

@skotch40 Glad you enjoyed it mate. Did you see my latest test of the v 18 firmware?

[grey0powerlessnesss]

Another use is to monitor traffic around the car, in case of accidents, criminals, etc. It's cheaper than losing my no-clain bonus or the $500 fee that I must pay if the car insurance claim is not my fault.

[bobflyman]

@grey0powerlessnesss That's true. You can set it up in continuous loop recording useful as a traffic monitor.

[MrSquishedsquashed]

I just glue the ring to 1/2 the case so I can still open it in case I need to replace the battery.

[bobflyman]

@MrSquishedsquashed Yes, I thought about doing that too. Good idea.

[kasuno1]

You cut it to make it parallel to the lens right? I don't understand much English, also it looks to me it's already parallel without cutting, but i suppose it's that.

[bobflyman]

@kasuno1 Yes that's correct. There is a curve to the front of the case, so if you don't cut it the lense will not be facing correctly forward.

[RamjetAlpha1]

Thanks Bob!  Is there a reason you dd not split the case and remove the board, then do the shaving and boring work with the case halves together?

[bobflyman]

@RamjetAlpha1 No reason why not mate, I guess you could take out the board to avoid getting debris on the lense, but you still need to put the circuit board back in before you glue the ring on. You won't be able to open the case after you have fitted the ring!

[nztitirangi]

@bobflyman perhaps you could 1. remove the board, 2. run the re-assembled case across sandpaper to flat, re-assemble cam then superglue the steel ring. Although a new case altogether seems better approach. Something that might support nikon SLR lens mount could be the go...

[bobflyman]

@nztitirangi Actually that would give a very good surface I must say. I wouldn't use super glue though as when I used it on sun glasses once the vapours completely ruined the edge of the lense. I think it would completely f.ck the 808 camera lense. hence I use 5 min epoxy. That seems ok.

[meandjesus4ever]

HI were did you get the lens?? i think i will hot glue my ring on because the epoxy would be hard or impossible to remove without damage to the lens ring! when you have to replace the battery inside the camera

[meandjesus4ever]

@meandjesus4ever never mind seen the lenses part numbers at the end of video THANKS

[bobflyman]

@meandjesus4ever My lense came from DealExtreme, part numbers are at the end of the video. Hot glue would probably be ok. When the battery does need relacement, which shouldn't be a for a couple of years, the ring breaks off the epoxy quite easily so you can open the case. Of course you then need to re glue it, but usually the smooth surface where the ring sat is still there.

[hakank1]

Thanks a lot for your efforts making the video! I think I go for a wide angle lens right away.

[alexinshade]

Cool beans! It's even evident there is much less shaking in the side-to-side comparison.

I ordered a cheapo Jelly glued fisheye lens, still waiting for it...

[bobflyman]

@alexinshade I've had 2 or 3 jelly lenses, they are ok for the money and for experimenting abit, but won't really do the camera justice. The DealExtreme lenses are glass and pretty sharp.

[alexinshade]

@bobflyman Well you got me thinking. I'll play a bit with the plastic lens and then decide. I see the x0.67 lens is also on ebay for a bit less then on DX. The fisheye is probably less practical with the dynamic movements because of the field distortion. I'm using the cam when mountain biking.

Thanks for the videos btw, some of them helpful, some are plain nice to watch!

[darkgilson]

How wide in degrees do you estimate the .67 lens? It looks a lot better !

[bobflyman]

@darkgilson when I get a hance I'll try and work it out.

[bobflyman]

@bobflyman OK angle of view of lenses as best as I could work out. Normal lense =

32 degs.... 0.67x wide angle= 60 degs... and fisheye = 92 degs. All give or take a couple of degs.
