Topic: Digital Cameras on Gigapan / High Capacity Battery Hack for Canon PowerShot SX40 HS

Thanks David. I’m not deterred – that’s the kind of life I get from the packs on my G9 so I obviously went ahead and bought the SX40.

This way I just have more power options for the camera, and it was a fun project to hack together.I’ve had camera batteries die in the field which cut short a couple of “GigaPan safaris” because I was on my last pack. I also may be able to get 3000 shots or so from a pack of AA batteries, which could come in handy for REALLY high shot-count panos.

Topic: Digital Cameras on Gigapan / High Capacity Battery Hack for Canon PowerShot SX40 HS


Consider a few things about actual power consumption during a GigaPan. Manufacturer estimates are based on normal shooting scenario. However, GigaPan shooting can be quite a bit better. Power consumption can be minimized and you can take far more pictures than the estimates would lead you to believe. Big power consumer is the display backlight. Either turn it off or minimize brightness and review time. The second big power user is autofocus. Normally it is not turned on, but it will save a lot if off. I took 1859 photos for a 12.5 gigapixel pan with a Canon T2i whose battery rating is around 400 shots. So don’t let the rating deter you when there is no AC around.

Topic: Digital Cameras on Gigapan / High Capacity Battery Hack for Canon PowerShot SX40 HS

I was looking at replacing my Canon PowerShot G9 with a PowerShot SX40 HS. It looked like a great camera for gigapanning, but I was worried about battery life, based on Canon’s published specs (roughly 500 shots per battery) and several test reports. There are few things I hate worse than having to take the camera off the GigaPan robot to replace a battery or memory card in the middle of a panorama. It rarely ends well.

After a bit of research, I found that there’s an AC adapter for the SX40 that connects to the camera through a dummy battery pack. It’s rating is 7.4vDC/2.0A which is just about exactly what you get from six Sanyo Eneloops. I was a bit worried about over voltage, until I tested the stock battery pack and found that it puts out around 9vDC.

I had “hacked” the battery pack connector in my original silver EPIC to use a battery tray with a standard 9-volt battery-type snap connector, so I had all of the parts around to connect one of those battery trays to the dummy battery from the AC adapter.

I’m happy to report that it works like a champ.I expect that the eneloop packs will give me well over 1000 shots per tray, and I won’t have to take the camera off the robot to swap batteries – just snap on a new tray.

Total cost including the AC adapter set is about $60.


Here are a couple of photos of the finished product. I’m still debating whether to mount a bracket or some velcro to secure the battery pack, but for now it sits just fine where it is in the photos.


EDIT – one additional benefit is that in cold weather you can attach an extension cable and keep the batteries in your pocket to keep them warm. My next project is to find a way to add a snap connector to one of the snap-in trays that come with the new EPIC and EPIC 100 while still being able to fill it with batteries. For long panoramas I want to be able to attach a second pack in parallel when the one in the imager starts to run down.

Topic: Gigapan Mechanism / Plug spec for elect. shutter release

Aloysious, good question. I doubled up on the relays because of the way the Panasonics cable release works. The panasonics use a one wire,two different resistance values method – where the camera measures the end voltage of a current loop to detect if its focus or shutter being activated. I originally tried doing it with just one shared circuit, but it was changing the resistance in the loop and did not work, the two stereo cameras need independent circuits. This is not the case with the Nikon 10pin system, which can allow control of multiple cameras with one circuit (it uses two separate connectivity loops, one for focus, one for shutter, so no resistors needed, also, I have had success with Nikon by just using optoisolators so no mechanical relays needed.)

You could probably figure out the required resistance for two Panasonic cameras, but then the circuit would not work with just one camera. Also, I think the cameras themselves when plugged in together on the same circuit were changing the resistance in the loop and crosstalking, they really needed independent circuits.

Topic: Gigapan Mechanism / Plug spec for elect. shutter release

Jason, just wondered why you doubled up on the relays when adding another camera.

Surely one relay should be able to cope with the low currents from the firing/ focus circuits of several cameras?

Topic: Gigapan Mechanism / Plug spec for elect. shutter release

Hi Tom,

I have used the Panasonic cameras and had to build an electronic release for them. The best way to start is to buy a cable release for it off ebay and start modifying it from there. The Panasonics use a couple different resistors for the cable release signal, so its not as straight forward as a Nikon, but very doable if you can use a solder iron. I am not an electrical engineer, just a hacker, so I might not know the best way to do it. My solution is probably more complex than it needs to be as I would use an Arduino mini, two relays, two resistors, a battery to power the Arduino. I have code and sample schematic in the old forum. I can’t think of a really easy way to trigger the Panasonics without some additional electronics (even the epic pro does not support it)

Basically, you use the Arduino Mini to listen for the 5volt digital pulse from the Gigapan on a digital pin set to input, and then have it do a digital output conncted to a pnp transistor to switch a reed relay, the reed relay makes the connection inline with the resistors to fire the Panasonic. In my version, I used two digital outputs, two transistors, and two relays so that I could individually control both focus and shutter- but I have stopped using autofocus due to occasionally missing frames (some sort of feedback loop is needed to detect if the shutter actually did fire and if not, stop the Gigapan, retry shooting, and notify the photographer- but the epic 100 does not have a feedback input- the Epic Pro does) If you are not seeking a programmable focus delay and just want to fire the shutter, its might be possible to skip the whole Arduino and have the Gigapan signal trigger the pnp relay to power the relay and make the connection for the camera shutter (with the resistors inline)

Sparkfun.com sells the Arduino Mini for about $20, I can give you the code needed to program it, but you will have to assemble the rest of the parts (all available from RadioSchack, two reed relays, a pack of pnp transistors, the two resistors {not sure thier values right now, but I can check later}, a small predrilled circuit board, a wire wrap too and wire, a 9v battery and clip, a switch to turn it off, the plugs to connect to camera and Gigapan, and a little box to put it all in, all less than another $20)

Learning Arduino stuff is fun too.

I build one of these to fire two Panasonics for stereo gigapanning, so I used 4 relays to simultaneously fire both cameras with each trigger pulse- it took about one evening to build (I am not scared of the solder iron or putting this stuff together, but this not really beginner project)

Good luck, I think you would be happy with the Panasonic on an Epic 100, size should fit well. The Sony NEX7 seems like a great choice as it has a nice 24mp sensor, but Sony has NO cable relase options for it!

The new Nikon d3200 seems like a good choice too, easy to build the shutter release, would fit on Epic 100, 24mp APS-c sensor, and great Nikon glass.

Let me know how it goes.

Topic: Gigapan Mechanism / Battery recommendation EPIC/EPIC 100

I’m happy with my nickel-zinc (NiZn) batteries. They have a higher voltage than NiMH (nominally 1.6v as opposed to 1.2v) and you can hurt your GigaPan if you’re not careful. I cut a slug of metal from a curtain rod, the same length as a AA battery, and wrapped it in tape to be the same diameter. I use the slug and five NiZn’s in the battery tray and get a bit under 10v with a freshly charged set. Once the batteries run down and the voltage drops, I’ll swap out the slug for another NiZn. They hold their power better in cold weather too.

Topic: Gigapan Mechanism / Plug spec for elect. shutter release

The old forum is a treasure trove of great information, and it still exists, just can’t add new stuff. Its at http://forum.gigapan.org

The Epic100 has an official electronic trigger cable for cannon cameras, and for others, you will need to roll your own (5v pulse could trigger a relay or opto isolator) I know I had rigged something up in 2008 for a Nikon d200 using opto-isolators. What camera do you wish to trigger?

Topic: Gigapan Mechanism / Finding Nodal Point in Canon 100-400mm

Just to save you some time, as you swing the camera side-to-side, observe the way the more distant object moves in relation to the near one:
If distant object moves OPPOSITE of swing; tripod-screw-to-pivot distance too LONG
If distant object moves in DIRECTION of swing; tripod-screw-to-pivot distance too SHORT

In other words, if you swing the lens to the right and the distant object moves to the left of the near object, your pivot point is too far from the tripod screw.

Topic: Gigapan Mechanism / Few questions

I’m using PowerGenix nickel-zinc (NiZn) AA batteries in my Epic 100. They have a higher voltage and I use five batteries and a slug cut from a curtain rod in the GP battery tray. If the batteries are getting low, I’ll swap out the slug for another NiZn battery. NiZn’s have higher voltage (1.6v) than NiMH, do better in the cold and have a longer shelf life. They also are less toxic when recycled than NiMH batteries. I bought mine from Thomas Distributing but I know B&H also sells them.

Topic: Gigapan Mechanism / Voltage

mskp’s link is dead, but I had copied the following from the thread:

Re: Battery Life Problems
In a prior discussion Stoney Vintson stated “Never exceed 9.6 volts. You may damage your imager electronics if you exceed 9.6 volts to the linear voltage regulator.” These NiZn batteries would be at the max limit, providing they don’t have a higher ambient (idle) voltage as do lead acids as the initial surge could do damage. Perhaps GigaPan could test these cells as it might solve some of the battery problems.

Re: Battery Life Problems
by Stoney Vintson on Wed Aug 19, 2009 4:19 pm
Actually we have been using the Energizer lithium batteries which are usually 6 batteries in series * X volts = 9.4 to 10.4 volts. The voltage is fed to a linear regulator which needs the voltage to be in a certain range in order to output a particular voltage such as 5 volts.

[end of copied thread]
On my Epic 100, I routinely use over 9 volts. On my previous early-version Epic, I once gave it about 10.6 volts (IIRC). It clicked and shut down. When I fired it back up with a lower voltage, it had reset everything to factory defaults but showed no damage.

On the old forum (which is now gone) someone posted a spec for the plug GigaPan uses to connect their electronic shutter cord to the robot. Does anyone still have that information? I want the plug that goes into the robot, not the camera, on the Epic 100.

Ron, of course you may hack! But dont start there, start at http://www.stereopan.com/ipan, it already works as a general purpose renderer!

The image pyramid render-er is open source. It works wonderfully on the desktop and iOS devices. It has better speed than Seadragon, but missing much of its animation and inclusion technology [ie. layers on top] (how much can you expect out of 600 lines of javascript?) It only works well on HTML5 hardware accelerated <canvas> browsers (all modern incarnations work well- ie, safari, opera, firefox, chrome) The coding is soo efficient, it should only take 3 months to wrap your head around it entirely and understand its magic (that was my timeframe at least).

That’s great, Jason! Do you mind if I hack (ethically) your JavaScript renderer to play around with this on my own site? I’ve been meaning to explore whether the <canvas> tag would provide an HTML5 compatible way of rendering GigaPans (especially for non-Flash capable devices) – I see now that you’re way ahead of me (as usual).

Topic: api.gigapan.org / API JPG dimensions

So I could not resist myself, I thought, could this tile composting be done in a javascript <canvas> tag entirely in the browser? So I came up with this image pyramid render-er for a very large canvas. Seems my browser could only handle a canvas width of 8000 pixels, so I set this as the upper limit. This is rendered entirely in javascript, use it sparingly as it requests all tiles for a width of 8000 pixels image. Its 4x larger than the api offers.
