  1. Atlanta legend Freddy Chancellor
  2. Anybody know this guy?
  3. Diego, at the moment I am testing and researching an hd-sdi solution. I have known others who have used standard deff sdi over baluns like these, but the hd-sdi specifications require a much broader bandwidth. I believe many utilize down converters on hd shoots.
  4. Recently modified my designs to accommodate xlr input and output on both ends. Check it out!
  5. There is an app that I've used successfully in the past for PCB layout called Kicad http://www.kicad-pcb.org/display/KICAD/KiCad+EDA+Software+Suite it's free, cross-platform, and will export gerber files for uploading to any fab house, even print yours out for etching in your kitchen. the downside, it's not very intuitive, but lots of literature online for getting started.
  6. Making a few of these for a friend. This time in shiny aluminum
  7. If you're interested, I'd be more than happy to build one for you, or others. Shoot me an email at dana (at) simmons-audio.com
  8. Thats a reasonable solution. I'll add that functionality to my to-do list.
  9. Hey Jay, yes, it is possible, and I've read through the Belden papers, lots of good resources there. The problem is relying on the village end of these boxes (which are notoriously neglected) to be properly grounded and such to allow the balanced line.
  10. Absolutely, I can customize with RCA's or a combination of bnc, rca if needed.
  11. Lots of room for other do-dads inside the case, so make suggestions!
  12. yup, that's it in a nutshell. There is some resistor magic in there too which adapts the LTC to a more iOS friendly level. But you get the idea.
  13. Here's a little diddy that uses the gpio of the 788t to switch the timecode on/off to your iDevice (iPhone/iPad) in order automagically roll MovieSlate,
  14. If anyone has ever looked at the output of the voltage from a cheap power inverter on a scope, it is way nastier than what TC looks like and much higher voltage!! I'll put a small amount of money on the problem being caused by dirty power. Cheap inverters are even KNOWN to cause problems in TV displays, why not cameras too? Bellow you can see to waveforms, the first is from whats know as a "sudo-sine wave inverter", the second is a "true-sine wave" inverter and is a proper AC source.
