Chronos User Discussion / Fantastic macro lens on eBay.
« on: April 23, 2018, 06:01:21 PM »
Found a fantastic macro capable lens on eBay. I have been playing with it for awhile and think I should share it with everyone else.

Not a super expert on lenses, but want something where you can shoot from a few inches away? I've found the lens.

There are several auctions with this lens or its equivalent. It appears to have been sold under several names. https://www.ebay.com/itm/NAVITAR-MACRO-1-8-12-5-75mm-C-MOUNT-ZOOM-LENS-16MM-MOVIE-CAMERA/281769329972?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649

You can focus until the subject is literally a fraction of an inch from the lens. (Not a good idea, but you can do it.) In the following videos the lens was about 3-4 inches from the tuna. Only reason i didn't go closer was because the cat would knock the camera out of the way.

A fantastic deal for $100 for the used ones. (Plus Shipping) The ONLY downside is that it clips the edges of the image when recording at full resolution, as it is a 16mm lens and not a full 2/3". Record at less than full resolution and you won't notice it. Note: You will need a C-mount spacer ring, but those are easy to come by. Also, mine came with a polarized filter. I swapped it with a UV filter as a lens protector. It takes standard 49mm ones.

Hope everyone finds this helpful.

I have some VERY minor "flicker" with my 100W LED modules. Not enough to be unusable, but still there. I would advise buying one module and testing before buying a bunch.
Yes, i could also just reccomend that.
(If you are patient enough to wait two times for the Delivery from China and also if you care about your money)
I paid a bit extra and ordered from a US seller. There usually is a couple who ship from the US.

Chronos User Discussion / Found lens spacer rings for cheap.
« on: March 09, 2018, 09:08:00 PM »
Well I have been getting more and more comfortable with using the Chronos. However, one thing that continues to annoy me is how far away the minimum focus is, especially with how small some of the things I want to film are and not having the ability to use an HDMI monitor. Unscrewing the lens and spacer technically works, but reproducing your lens position is impossible and leaving your lens loose like that is an accident waiting to happen.

With my testing, it looks like adding 1.5-2.5mm of spacers with the Computar 12.5-75mm lens will let me focus down to 6-12" from the subject. The penalty in terms of image brightness is virtually imperceptible.

Some places online want several dollars per spacer. Thankfully eBay gives us more options.

https://www.ebay.com/sch/i.html?_from=R40&_trksid=p2380057.m570.l1313.TR0.TRC0.H1.XC-mount+Lens+spacer.TRS0&_nkw=C-mount+Lens+spacer&_sacat=0

I personally ordered some of the .5mm out of tolerance spacer rings from Singapore. Copper is soft enough that I'll be able to open them up slightly with my set of mini-files if I need to.

I figured I would post this in case others wanted to get some spacer rings of their own.

What save format are you using? Dumping the whole buffer with the default compressed format gives me files that are only about 710 mb.

You may want to post more information about the settings you are using.

Also, is it okay to mix and match ran in the cameras long as it is all compatible. ie, can I use the 16 gb stick my camera came with and just slap in an additional 16gb stick?

I suppose I could just pop open my camera and see what make/model it already has and go hunt down another one of those.

Splitting this up into another post since this is unrelated to the last issue.

When "Auto Save" is selected, pressing "Stop" on the touch screen causes the camera to begin auto saving. The problem is that there is no way, that I can see, to disarm the camera when auto save is enabled. You will have to let the camera start saving and then abort the save, which is both inconvenient and puts lots of files on the memory card you never wanted to put there in the first place.

Don't know what the best solution would be, but figured I should mention it.

My Chronos has locked up while testing to see if the issues with .3 have been solved.

I was had my camera plugged in on my desk and I was having it simply auto save the whole buffer at the default 1,000 FPS. Once I saw it had finished I would hit record and save the whole buffer after enough time had passed for it to fill.

I left the camera running overnight, recording a few more buffers worth of video as I got ready for work. I leave the camera running during the day on my desk, then come home and start recording more.

After one such save, the camera gives me a grey screen. I try to record, but it fails. I go into the settings and I cannot change the resolutions. I go out to the main screen and the camera gives the "Shutting down" message, but locks up on this screen until I hard power it down.

The card is 64gb and saved video until it was 29.8gb filled of 59.4gb (Don't know if this is relevant.)







Camera works fine after the hard reset.

Chronos User Discussion / Re: Found a good foot trigger.

Great idea! Unfortunately it's currently unavailable.

Well poo.

I went and looked around online and found the makers site where they appear to still be available.

Chronos User Discussion / Found a good foot trigger.
« on: January 07, 2018, 06:07:55 PM »
The "stock" BNC trigger is nice, but it is handheld only as well as needing to be in your hand to trigger. (It's not practical to have your thing happen and then pick it up to trigger.) When shooting rifles and many handguns (Especially the sawed-offs.) by yourself, things can get difficult.

I figured the obvious solution would be to find a foot pedal type trigger. I went on Amazon and after a little searching I found this foot switch, originally for tattoo machines.

https://www.amazon.com/gp/product/B01G1JQONK/ref=oh_aui_detailpage_o05_s00?ie=UTF8&psc=1



I bought one and I am happy to report that this is a fantastic addition to ones list of Chronos accessories.

This pedal and pedal base appears to be made of some non-magnetic cast metal. This gives it a good amount of weight and makes it plenty strong for the task. It looks and feels like it should provide years of use under the most foot-stompy of people. (Provided you don't use it to anchor a boat or drop bowling balls on it from a 3rd story window.)

The "Switch" feels like it is just two terminals, one on the foot pedal and one on the base, making contact. Nothing fancy and perfectly adequate for the task. The spring that holds the pedal up is of moderate strength. Strong enough to prevent accidental triggering if you move it by sliding it with your foot. The bottom has some of that non-slip stuff on it.

This also makes a great "Slapper" hand switch. No need to pick up or hold anything, set it on the table or counter and slap it when you need to trigger the camera.

One thing to note is that the one I received has a RCA connector, not BNC. The cable it comes with matches what the pedal is, but you won't be using the cable it comes with, so plan appropriately.

Hope everyone finds this helpful.

We've experienced the same issue over the Christmas break, with the camera saying there's no free space when there clearly is enough. We'll be fixing that first thing when we go back to work tomorrow. I'll post here when we have a fix.
Thanks for the update.

Overall this is a very good update. Just one minor bug for everyone.  ;D

Same here today. I use a 64GB SD-Card fat32 and after 3,39GB of PixelStuff the  Camera said nope. Enough is enough.
But i got all my Firework-Stuff on Video so i dont really care c:
Yea, finally got around to updating my camera.

New version works great, but on h264 the files now take 700 MB each. That is not a problem, always good to have max quality and edit down in post, except for the fact that I am running into the same 4GB save limit, on a 64 gb card, that others are having

Software Dev / Re: Saving setting across reboots is BAD
« on: January 01, 2018, 07:33:05 PM »
I personally love the save settings after reboots  please leave it
Same. It's incredibly handy, especially when you get things setup absolutely right, but need to shut down the camera to move things around for whatever reason

Hopefully there is an easy way to perhaps have the setting be toggle-able on and off.

I have wanted to get a clip that would be along the lines of the one Taofledermaus has on the main page that would be suitable to potentially use as an example of what the camera is capable of on the main page.



I think I might have done so with this one of my Taurus 445, 44 Special.



If someone is better at making GIF files, I can provide the raw video.

Diagnosed a mechanical problem with a typewriter using Chronos, decided to turn it into a video. Loving this camera!

=)

Very cool vid!  I wonder how much longer it'll be before the general public doesn't even know what a typewriter is...or are we already there?  :D
Lets be honest, there is lots of old stuff that is cool to look at, but you are happy you don't have to actually use.

I have been going to the steam thresher reunion in Rollag, MN ever since I was a child. Lots of fantastic machines. Glad we don't have to run our society off them anymore.
