Hi Chris,

Just getting back to my Chronos after a long layoff with life getting in the way!!!

I thought I would upload the latest firmware (ChronoTimer_Ver_1_3_11) however the upload fails every time & I also tried (ChronoTimer_Ver_1_2_7_TROUBLES_FIXED) & (CHRONOS_2_0_JAN_23_2013) no go. I get out of sync issue.

I had to reload (_20121028_Chronos_ArduinoR3_HDR_Clean) to get it to work again.

Have you changed the Arduino requirements? I have UNO with atmega328?

Any ideas?

Thanks.

Steve...

ps. Like the web site, a bit slow from AU.

Steve! Glad to hear from you! I hope a long "layoff" means something different in Oz than it does here. Regardless i hope you are doing well!

yeah the website is having some issues, im trying to work through them. One of the plug-ins seems to be causing the delay.

If i remember correctly we sent the parts and you did the build? this was back in 2012? I think this is before we moved to the Arduino R3. Did you assemble the Chronocontroller? Can you refresh my memory on this?

There have been some minor changes here and there, nothing huge. My first suspicion is arduino reworked thier boards and are now on revision 3. Some things had to change for it to work with the code.

I think your controller is all hardwired right? using the protoboard and such?

that overall design should be fine. You probably just need an R3 arduino (the silkscreen on the back of the R3 is white, not blue)

Then you will need the Arduino IDE 1.0 or higher.

I do recommend moving to the newer code if possible, it is far more robust, it is more efficient, and it just runs better in general.

we may have to make a couple adjustments to get everything working on your controller.

Hi Chris,
You are right on all accounts, by a layoff I was referring to no timelapse photography.
I have a blue UNO, so I will get a R3 version and try again.
Thanks.

Steve, keep in mind the buttons may not be correct int the new code, and might require some code modification. let me know if i can help with this.

Hi Chris,

I have been able to get it all working with the new Arduino.

Now I'm trying to trigger a Gopro using a cam-do wired remote, see here http://cam-do.com/wired.html

All works fine if I manually trigger Gopro, however I get no triggering when I connect Chronos.

It looks like the cam-do wired remote needs a short to trigger & Chronos only drops to about 45 ohms.

Any idea how I might fix this issue?

Thanks.

Steve...

45 ohms is pretty low, at least, it's enough to trigger everything else. Maybe the issue is not the 45 ohms but
the duration of the shutter signal? Have you tried setting BULB to 1 and seeing if a longer signal triggers it?

Trigger length was the first thing I thought of, I did try Bulb at one second. I even tried 5 seconds.

Gotcha.
You could always replace the Optoisolator with a 5v relay. that should work fine. I used to use relays in the first design of this system. I moved to optoisolators because there were less moving parts and dont make that clicking noise.

Hi Chris,

Ok good idea.

Thanks.
