Post Bulb Ramper Shield for Arduino
Hi all,

Here's a sneak peak of the dedicated bulb ramper that I'm working on. I hope this will be a feasible replacement to the Little Bramper. The first prototype is built, and I'm just working on the code. It will be available as an Arduino compatible shield, or a Standalone version (run by 2x AA). The bulb ramper will not work with Nikons.

Features:
Regular Intervalometer or Bulb Ramper.
Millisecond timing precision.
ISO or Aperature stepping.
Stops/100pictures and Stops/hour displays.
RGB LCD screen.
Flashlight.
Auxiliary trigger output (to connect to motion systems like Dynamic Perception or Chronos).
Easy to update or hack the code.

Image

I'm at the stage where I can still take input on features that would be of interest to the users, so don't hesitate to mention anything feasible for inclusion.

Also, there has been talk on these forums in the past of gathering ramping information to make a fully autonomous bulb ramper. Basically the user would enter their location, date, and time, and the bulb ramper would use a ramping profile based on the input data. With the bulb ramper shield, I am planning to be able to "save" the ramping data, then volunteers can later upload it (via the serial monitor in the Arduino IDE) and then email it to me. I don't know if I will progress to a fully automatic bulb ramper in the future, but I would certainly make the data available to anyone who is interested.

I think getting data for ramping would be beneficial to us all. To get meaning full results you would have to standardise the process.
Avoid the clouds and sun in the view finder and say point you camera at the zenith. Shoot a way a couple of hours around sunset on a clear blue sky day, making sure its not going to be a full moon rising. ;)

Post Re: Bulb Ramper Shield for Arduino
I know. I've been thinking a bit about it

I would need to know the latitude and longitude, date, time the timelapse started, and time of sunset.

A multiple choice type of standardized answers would probably be simplest in terms of describing the scene and inputting it into a future controller. Then the controller can "tweak" the curves based on historical data.

Then I was thinking of something like the following:

Describe camera orientation:
1. Towards the sun
2. 45' from the sun
3. 90' from the sun
4. Away from the sun

Describe the scene:
1. Flat horizon
2. Mountanous horizon
3. Close city
4. Distant city

Describe the amount of clouds:
1. None
2. A few
3. Many
4. Overcast

ect.

Post Re: Bulb Ramper Shield for Arduino
The only thing that I could think to add as far as hardware would be another aux trigger.

I would love to see a bramping device that could take in a trigger, execute the exposure, and then tell an external device it was complete.

For example, the MX2 could trigger the bramper, then when the exposure is complete, the bramper would tell the MX2 to move. Then once the MX2 moves, it would tell the bramper to take another exposure.

Post Re: Bulb Ramper Shield for Arduino
I think one aux trigger will be enough to interface with motion controllers. I talked to Jay and Chris and both their systems can operate as a slave with an input trigger. In this case, the Bulb Ramper would be the master (responsible for proper timing), and the motion controller(s) would be the slaves.

Post Re: Bulb Ramper Shield for Arduino
Yeah, if using a bulb ramper i would preffer a dedicated device to provide the timing. Just connect the bramper shutter output to the Input on Chronos and put it in Sync GO (SGO) and it will sync right up.

As I mentioned earlier, the Bulb Ramper Shield will be available in a standalone version (no arduino required). You will still be able to solder on pins and use it as a shield if you want to change the code or download the ramping data.

I havn't done a battery life test yet, but when it is in standby, it draws 40ma - 120ma (depending on screen brightness), and when it is running it draws 70ma - 200ma. Using AA cells with a capacity of 2500mAh, I would expect a run time of at least 10 hours or so. There is also an input jack for 6-12V DC if you prefer to use a power pack that you may have already. Automatic switching is done smoothly between the AA cells and the external power.

To get started i was thinking of doing the following "calibration".
Start recording at the local solar noon on a clear blue sky day.
Use say, 50mm lens and point at the zenith.

1. Latitude
2. Date and time ( in UTC )
3. Angle and distance to local horizon unless setting sun over water which would be ideal for now !

These results should enable us to formulate a basic model of the sun's lighting and be repeatable anywhere on the planet.

John
Q.? Is it jumping the gun to do it now as I dont know if the data from the exif file will do OR wait till your "Shield" is ready to go? I am :-)

Post Re: Bulb Ramper Shield for Arduino
I don't mind discussing this at all. Sort of a "community project". I will say that I am sceptical of a fully autonomous bulb ramper, as I expect there will have to be some human intervention in the final device.

Here's what I'm planning...
The Arduino has 1Kb of EEPROM that I will use. I figure that every minute it will log the current "Stops/hour" that the controller is set to. That would be up to 500 minutes of data points (2 bytes per measurement, over >8 hours).

Once enough input is gathered, it should be fairly easy to sort out the data. I'm quite fluent in Excel, so it shouldn't be too hard. I don't expect the data to be a perfect curve, but be up/down somewhat as the user tries to get the proper rate. That's ok. I can smooth the points in excel. The data points would describe the curve of the sun's descent in stops/hour. This would be independent of the camera's sensor size, focal length, as it is the change in ambient light, which is what we're after.

Also, the best data would be from say 1 hour prior to sunset (no ramping) to, say 4 hours after sunset (20 stops later). I know that most people wouldn't have a full timelapse like this, but if enough people contribute, I can probably fill in the missing points. There will be no wasted data. :-)

In a future controller, the user would enter their location, and describe the scene, and figure out a starting exposure, and there would probably have to be an onboard RTC (real time clock). Then the controller would ramp based on a calculated curve. The device wouldn't need to know the focal length ect because that's all taken care of in setting the initial shutter time.

I would like to know if there's anything I'm missing here. I think all I need to know are variables that would change the scene brightness. (location, time, date, city/rural, cloudy/clear, camera pointing west/east)

Post Re: Bulb Ramper Shield for Arduino
I think all those variables will be too much to automate it for now. However if we start with a basic setup which is repeatable and more importantly predictable anywhere else on the planet then human intervention can tweak for the main unpredictable varialbles eg clouds !

Just an update on progress...

Tonight I did the first test run of the Bulb Ramper Shield. There is significant flicker especially near the end. I suspect that is from the window reflections, but I will check it out. I also want to tighten up the timing algorithms and make a few adjustments.


Then I checked out the ramping data. Below is what I downloaded from the Ramper. Every line is one minute, and the second number is stops per hour that it was ramping at:

I put that data into excel and made a graph. I manually put in the arrows just to show where the sun disappeared (apparent sunset) and the official sunset time is.

Then I inserted the trendline and formula. A 5th degree polynomial was a close fit, but it's not perfect.

It actually works out tighter if I clip the 0's off each end:

From here I just need to run a few more tests and and figure out where the flicker is coming from. Also there's a couple bugs that I need to fix. A user's manual is in progress. The data logger is working, but I'm not sure if I have the capability to deal with the data.

Well Done. Interesting to see that flat curve around the time the sun disappears lasting for half an hour. What is your Latitude and where was the camera pointing?

Looks like you are doing great progress! Quick question: will it have USB support to control the camera?

I know I might be a little too late for suggestions, but it would be nice to be able to power the device from a 12v battery.

It was still ramping after sunset, I just didn't adjust the rate of ramping for 30 minutes.

Location 49.9N, 97.1W
Camera was pointing SW through a window.

Post Re: Bulb Ramper Shield for Arduino
So tonight it was cloudy out, so I thought I'd set up and run another timelapse.

Same start and end time.
Same interval.
Same location.
Essentially the same time of year.
Camera pointing the same direction.
Only difference was the clouds.



I've superimposed tonight's ramp data on top of last night's data.
On the clear night the total stops was 12. On the cloudy night the total stops was 9.8, everything else being equal.

So what is the units for the vertical axis then?

PS. Im around 43 South

Post Re: Bulb Ramper Shield for Arduino
Vertical axis is stops per hour.

eg, if I leave it at 8 stops/hr for 0.5 hours, it would ramp 4 stops. With a shutter time of 1 sec at the beginning, the final time would be 1 * (2^4) = 16 seconds. So just after sunset it's still ramping, but the rate of stops/hour is constant.

Maybe the graph below would make more sense. Its the first run's data (blue) in stops per hour, and the red line is the total number of stops ramped. A horizontal red line means no ramping. The steeper the angle, the faster the ramping.

I can see clearly now :-) the red line ( 1st graph ) is the way to go. Looks like both ( 2nd graph ) are 9 stops per hour then they go their separate ways.

Post Re: Bulb Ramper Shield for Arduino
Just an update on progress, I've been tweaking the code to improve the shutter timing accuracy.

Prior to changes, the shutter time was off ± 1ms, 24 times in 50 pictures. (i.e. the timing was within 1 ms 52% of the time)

By contrast, the JSR Intervalometer which I consider pretty good is within 1ms 60% of the time.

So I changed the code on the Bulb Ramper shield, and was able to get timing within 1ms 76% of the time. I figured there's probably some rounding errors because it doesn't display fractions of a millisecond. I made some temporary changes to the code to display fractions of a millisecond, and here's the results of the timing.

26% of the time it is within ± 0.10ms
62% of the time it is within ± 0.25ms
96% of the time it is within ± 0.50ms
100% of the time it is within ± 0.75ms

I think that's about as much precision I can get. I'm guessing the remaining inaccuracies are just limitations of the mechanical shutter and bulb mode in general.

Post Re: Bulb Ramper Shield for Arduino
Hi all,

I've been working at this project at a fever pitch lately, and I am finally ready to take orders. I will be posting a user's manual and code to the blog in the next few days. I'll also try and make a video tutorial as well.

That being said, I haven't had been able to do an extensive trial period yet. The weather has been too cold lately to get outside and shoot timelapses. For this reason, I expect there to be regular updates to the code as I get feedback from users. If you order a standalone version, just be aware that it is more difficult to update the code (and you need an Arduino Uno to perform the update). The code definitely works, but it isn't the final version yet.

I'm offering a 15% discount on orders placed before April 15th, 2013.

Pricing will be:
Bulb Ramper Shield (arduino required): $85 ($72.25 with discount)
Bulb Ramper Standalone: $115 ($97.75 with discount)

Included is:
3.5mm to 2.5mm cable
3.5mm to PC flash cable
3.5mm extension cable

If your camera needs the N3 connector (50D, 7D, 5D ect):
Canon N3 Adapter: $10 (discount does not apply)

Shipping will be around $10 - $20.

You will also need to supply your own:
Arduino (for the shield version)
2x AA Batteries (for the standalone version)
Camera :)
Optional 12V power source. Both the Arduino and Bulb Ramper Standalone have a standard 5.5mmx2.1mm DC power port.

For orders placed on or before Monday, March 11 2013, I will order the parts, and assemble the units that weekend. Shipping for the first batch will likely be on March 18, 2013.

Post Re: Bulb Ramper Shield for Arduino
I've been getting some inquires from interested people and I thought I would post the answers here for the benefit of all:

Quote:
What is the difference between the Bulb Ramper Shield and the Bulb Ramper Standalone versions?

The difference between the Shield and Standalone can be summarized as follows:

The Shield version is like the assembled MX2 DIY Kit. It requires an Arduino Uno to run, but that makes it easy to upload new code. It can be powered from a USB or the 12V external jack on the Uno.

The Standalone version does not need the Uno. It has the Atmega328 built in, as well as a voltage regulator circuit. It is powered by 2x AA batteries and also has a 12V jack for DC Power. The Standalone version can be converted to a shield by soldering on header pins, and inserting it into a Uno that has the '328 removed.

The Shield can not be easily converted to a Standalone.

Note also that I do not supply the Arduino, you will have to get that yourself if you get the Shield. Also, buying a Shield ($85) and Arduino ($30) would be about the same as buying a Standalone ($115), so you should weigh the benefits of both without regards to the price.

What is the difference between the JSR Intervalometer Kit and the JSR Bulb Ramper Shield?


The JSR DIY kit is a "jack of all trades, master of none" type of device. It's an intervalometer, motor controller, stepper controller, motion ramping, sound trigger, IR remote, has an aux I/O, ect. Yes it also does Bulb Ramping, and it works well, but that's not why it was designed.
(ie, you can only set a rate in "stops/100 pictures", and you can only aperture step in whole stops)

The Bulb Ramper Shield focusses on bulb ramping and has better features for that purpose. You can step in "stops/100 pictures" and "stops/hour", which is more useful. You can aperture or ISO step in fractions or multiples of a stop. It has collision alert and manual x-time settings. I've also included Interval Ramping and Interval Oscillator. You can also easily connect the Bulb Ramper Shield to the MX2 and have bulb ramping with motion control and all the benefits of the MX2 controller.

Post Re: Bulb Ramper Shield for Arduino
For now, just send me an email or pm. After I build the first batch I will have a link on the blog. Sorry if this is less than obvious, but Paypal doesn't have a "place order" button, and I only want to bill you when the units are ready to ship.

Post Re: Bulb Ramper Shield for Arduino
Will the stand alone version have the pins, so it can updated? Looks like it might be a squeeze to add them later.

Congratulations on the project. Looks great have ordered one!

Post Re: Bulb Ramper Shield for Arduino
I was not planning on including the pins on the standalone, but I can add them if you're interested. It looks tight, but they can be soldered on with a regular soldering iron.

You would have to take precautions that nothing shorts across them during normal use. That could cause damage.

Post Re: Bulb Ramper Shield for Arduino
This looks awesome- cant wait to get one. I have a really basic question though- why do you have to connect it to the hotshoe with a cable if it is controlling shutter time etc through the remote input?

Also, id second the idea of adding pins to the standalone to allow updating, unless the software is as close to perfect in the first place as you think you could get it.

Cheers

No. If you can find a sensor and do some coding though, it shouldn't be impossible. The Aux port is on an Analog pin and the Hotshoe port is on a Digital pin (interrupt 0, to be exact).

It's called "shutter monitoring". I wrote about it on the other thread. The hotshoe connection allows the Bulb Ramper Shield to see when the shutter opens and closes.
Quote:
After the controller triggers a photo, there is a shutter lag of between 80 - 300 ms before the exposure starts (average is around 150 ms). After the controller ends the exposure, the camera takes about 40ms before it closes the shutter (this delay is fairly consistent on my 60D, but I expect it varies among camera models). The result is that a timed pulse on the shutter cable (say 700ms) will actually result in an exposure of anywhere between 660 ms and 440 ms. For an accurate 700ms exposure, the camera has to be triggered, wait for the shutter to open, then the controller has to close the shutter BEFORE the exposure is complete.

You would still need an Arduino to do the updates. If you want an update, you could always send it back to me and I can update it for you. Consider the updates a bonus, not a necessity... after all no one could update the Little Bramper (no one even had the code for that thing...)

Just picked up an Arduino and a hot shoe adapter for my 6D. Can't wait to get my hand on this ramper!

Post Re: Bulb Ramper Shield for Arduino
I have added a "Buy it Now" link to place orders to the blog. Here's the shortcut: Buy it Now

You can select whether you want the Shield or Standalone version.
15% discount until April 15th will be included at checkout.
Basic shipping ($10.50) will be added at checkout. If you want a faster service, you can select an additional shipping option and add it to the cart. (Note: for international service outside Canada and the US I recommend the "International - Small Packet Air" service).

If you need a Canon N3 adapter or a DC power cable you can add those to the cart as well.
I will soon have an adapter available so you can use your MX2 camera cables with the Bulb Ramper Shield.

Post Re: Bulb Ramper Shield for Arduino
Mine arrived today in the UK. Loaded the software and fired it up (I got the shield version) . Looks great. Will be running a couple of tests as soon as the weather improves.

Thanks for a prompt service!

Post Re: Bulb Ramper Shield for Arduino
Hi all,

Just an update on things. As most of you probably noticed, the intervalometers I've designed have been sold out for some time. I've been busy at work, but the main reason is I am unable to continue with this hobby on a full time basis. I have been accepted to the seminary in Toronto to study for the Catholic priesthood, so designing and building intervalometers has to be put on hold indefinitely.

The good news is I will be releasing the circuit diagrams, gerbers, code, parts list, ect. for the intervalometers I have built. You will be able to build your own. The bad news is I will be unable to provide support or help if you run into difficulty.

I will be around for approximately 2 weeks yet. I would advise that anyone who has a question should email me, or post it here for all to see the solution. Also, I will put a donation button on my blog. If you've found anything there useful, please consider a small donation.
