About Piranha

  • Birthday 07/31/1954
  1. Andrew, I appreciate you were not aware of the complexity of Snaperture. The software is very extensive and I took great care (as I always do) to ensure that it was well structured and efficient. May I ask you, as a software engineer, if you are familiar with the Jackson Structure Method, or JSDs, as the diagrams are known? I swear by this methodology and would not consider coding without carrying out this planning exercise first. At work, my boss sometimes commented on the fact that my software took longer than expected, but once commissioned, he was delighted to be spared irate irate calling to report malfunctions. I also failed to mention a feature in my device, whereby the camera trigger can occur zero to ten seconds after the sensor activates, in one millisecond increments. This is just one example of a function that involves significant user interface, adding to the versatility.
  2. I take your point about my using this forum to "plug" the device and will refrain from doing so in future, but I feel I have to defend its capabilities and potential. This device is by no means a collection of separate, simple triggers, with on/off response. For example, the range finder can pinpoint distance to the nearest centimetre, up to four metres. This is a digital feature and involves signal sequencing in software, as you will appreciate. If one wished to sense that a body had come within a specified distance, then ensure that it's movement had ceased, followed by a light illuminating, then a noise occurring, it could not be realised simply by a handful of components in a breadboard. This is just a random example, of course, but demonstrates that this device has a great degree of versatility. I agree that if you simply want to detect noise, it is wiser to put something simple together with a few components, however if one wishes a multi-medium, quick response unit that is robust and portable, them more is required.
  3. BeBu Lamar, please tell me the secret of free components.
  4. Andrew, I agree that making a single sensor-activated trigger on a breadboard is cheap and simple. Making a multi-sensor, ergonomically-designed, programmable, robust unit, however, is neither cheap nor simple. Add to that the software involved in providing the user with a wide range of parameters, operational modes and triggering options, and you begin to appreciate the development costs involved. If you want a high-quality, permanent addition to your photography accessories, you should be prepared to pay for it. I agree that there are a few pieces of junk out there (well, I would say that, wouldn't I?), and I would point out that this was the driving force behind Snaperture.
  5. Being an electrical engineer, and a keen electronics hobbyist, one of the first projects I embarked upon, when I took up photography, was to build a reliable device that would fire a camera shutter when sensors were activated. I was unimpressed with what the market had to offer at the time; devices that could read a single sensor only. I designed my system to house a number of senors in its casing, eliminating the need to plug in microphones, PIR sensors etc. This saves on having to carry additional equipment, and allows greater ease of operation. An added feature is that the sensors can be monitored in sequence, allowing for complex triggering events. The four sensors are PIR, Range, Light and Sound, and there is also a real time clock to facilitate intervalometer operation. Recently I added an output port in order to drive the ever-popular water-drop apparatus. This gave me the opportunity to use the additional port also as an input, so now one of a range of external sensors can be added. What springs to mind is using this input to detect operation of a pressure pad, as an animal approaches, or to have an infra-red device that triggers the camera when a beam is broken, such as by insects flying. There must be a host of different events that demand instant reaction in order to photograph them. I am kindly requesting that members offer suggestions for the situations that could be captured using the extra input. Bear in mind that, as an electrical engineer, I can design any necessary circuitry, so no idea will be considered too ambitious. I have attached samples of its use. Thanking you all in advance, Piranha
  6. I agree the results might be just as impressive with video, however the thrill of instant reaction is absent. Have at look at this device. It doesn't need smartphone connectivity and has the sensors built in. There is no need to attach microphones, PIR sensors etc externally. www.snaperturepro.com
  7. There is a device that incorporates an intervalometer, as well as much, much more. Take a look at www.snaperturepro.com
  8. I doubt if you can get a response-time to match this, using a smartphone's microphone. The OS would introduce latency and an unforeseen delay of 1 mS might as well be a week. Photographing a volume of water, vaguely shaped like a balloon, is child's play by comparison.
  9. A dripping tap won't give you results like this.
  10. Camera triggers that rely on smartphone operation are introducing unknowns into the equation and this often produces erratic behavior. I have used a PIR sensor with consistent results, simply feeding the output into a microcontroller, which then fires the shutter.
  11. I need to change my Photo.net Personalized URL details. Upon enrolling it was not clear what should be entered here and I entered my website URL by mistake. I see no way to edit this and I fail to see why it is required at all; surely it should default to the user's name. Can someone please help me? Mod Note Thread moved to Site Help
  12. I use a system that produces very pleasing results. What device are using? I am not familiar with worthington jets, could you please give me the URL?
  13. Check out www.snaperturepro.com Unlike the Time Machine, this unit has the sensors built it, so there is no additional cost for sensors. Also, the sensors can be used individually or in sequence. The real time clock is included, rather than being an ad--on module.
  14. I am a total newbie myself, however I think I have successfully uploaded images. In the top-right corner of the screen, there should be a link for uploading, net to your profile picture. I hope this is helpful.
