There are some (not many) LED work lights that you can find in hardware stores that have smoothly powered LEDs.

Nice footage, and congrats on the subs.

Yet another free-fall-follow-focus clip.
Are you free-handing that?

It's a 1.4, but how about a microscope mount?

That may have been the same issue I was having. I was saving a large number of frames but it was a relatively small portion of the full recording, less than 5%. I'll try leaving more lead in and out.
Thanks.
edit: Updated my camera, tried saving both long and short segments but had the same issue and I was unable to cause it to happen on purpose,
It seems to happen more with low resolutions/high frame rates (>30kfps) but, again, I am unable to cause it to happen predictably so it may just be that I have been recording more high frame rate video recently.
Thanks.

I need to spend some time trying to reproduce this, as of now it is unpredictable.
I have had my Chronos 1.4 'overshoot' the end point when saving h.264 videos. I mark my start and end points and the save begins as expected but passes the end mark. The touchscreen then becomes unresponsive, the "abort save" button does not respond nor do any touches in on any other part of the screen. All that I can do after that is to restart.
I had it happen 3 times out of ~20 videos that I shot today, I have not run an online update since the summer (maybe a month after v0.5.0 was released) so I will try that and see if I experience the same.
If I ssh in, is there a way to get debug info on what is going on, or manually unlock-up the UI? Just curious, thanks.

This is the spray from an aerosol can of cooking oil. The nozzle forms 2 streams that re bridged by a thin film. When the film gets too thin it becomes unstable and begins to whip back and forth before breaking up into droplets. When releasing the nozzle the oil speed drops below some threshold and surface tension draws the two streams together.

I just noticed that if the focus aid is turned on it will be visible in the 60fps live recording. Not a problem for me but good to know before you go recording a lot.

The eject dialog works with my 2 USB sticks and a USB mSATA enclosure that I use.
v0.5 looks awesome, the UI is coherent and repsonsive, the web interface looks greats and the 60fps continuous is an awesome addition.

ExperimentalPerception, I noticed the flash of light with super sonic ping pong balls as well. As far as I can tell the air caught between the ball and the surface gets heated as it is compressed and is enough to cause the nitrocellulose ball to detonate, just a little.
What are the specs on your cannon? (Barrel length, air reservoir, air pressure?) I have 8 feet of 1-1/2" barrel with a 5 gallon reservoir at 80psi. I'm thinking of adding more barrel length at this point to get some more speed.

Yes, you set up a shared folder on your laptop/PC and the camera will save files to that folder. I believe there is a thread that goes into the setup in detail.

The camera is connected to the router with an ethernet cable and the PC is connected by WIFI. The setup will be the same as when you use the switch.

I am using one of these (unavailable) https://www.amazon.ca/Gigastone-Media-Streamer-Plus-Built/dp/B00NHWK01C but any wifi router will work. The only advantage to using a portable wifi router is having a self contained battery saves you from carrying an extra power cable.

I have a self contained router with one ethernet port and WIFI, I have used it to wirelessly control the camera as well as transfer footage. The setup is identical to using a wired connection.

« on: April 17, 2020, 02:58:34 PM »Is it possible to control the camera from your phone using this adapter?
I have a portable wifi-router/access point device (this one in particular but anything similar will work https://www.amazon.ca/Gigastone-Media-Streamer-Plus-Built/dp/B00NHWK01C). You can connect it to your camera by ethernet cable and then connect to the router device wirelessly with your phone or laptop. There are loads of clones that can be found on 'over seas' websites.
They are pretty cheap, keep the cable count down on your rig and isolate your camera from the internet/other devices.
