Welcome to the Strobit Triggr Project, an open source hackable wireless trigger used in photography lighting by using low cost strobe units triggered remotely via RF. This was started while trying to find a cost effective and reliable solution to the commercial alternatives out there. At one end of the market is the Ebay or Cactus Trigger, which is low cost but rather unreliable. At the other end of the market there is the industry standard, Pocket Wizards, very reliable, but very expensive (i.e. way out of my price range).

What I wanted to do was to create an open platform that anyone can easily build for a low cost and then be expand upon by the community. The pair of prototypes I’ve built were a proof of concept that I can get a camera to trigger a strobe unit reliably at a low cost. From early tests it appears that I’ve succeeded in my goal, but further testing is required.

I’m toying with the idea of putting together a low cost kit for the enthusiast. i.e. PCB, pre-programmed PIC, etc. So we could all benefit with a bulk order of the components. If your interested please email me using the contact form the top menu or use the mailing list signup on the right to give me an indication of numbers interested. Once I finaliaze the design and get some idea of numbers I’ll get a better idea of price. At the moment it will only be available in kit form due to FCC and other Licensing regulations.

Future Improvements:

  • Higher Sync Speed.
  • Frequency Hopping.
  • Forward Error Correction.
  • Power management.
  • UI to change settings, Channel etc.
  • Save settings in Flash memory.
