  1. Hi, I'm making a remote roll button for my 788T with a built in LED. The LED flashes when the machine is rolling thanks to the DE-15's logic out pin hooked to an Arduino. The whole circuit works perfectly fine when tested on my breadboard and powering the Arduino with it's 3.5V externally. I really wanted to power the remote roll button via the Ext. DC OUT pin on the 788's DE-15 connector so I can do everything with one VGA cable, but I'm having some trouble with the power that it outputs. I am using a DC to DC converter to step down the 13V coming out of my 788T's
  2. I guess you'd have to have one for each transmitter and connect to it first. This BT receiver has its own battery, but I was trying to figure out if it was possible to power it off phantom from the SM. It would cut down on size considerably.
  3. I had an idea of putting a bluetooth receiver between a sanken lav and my sm transmitter. The mic has a passthrough to the transmitter. I connect to the BT receiver with a cellphone and use the regular Lecrosonics RM app to set settings on the transmitter wirelessly. Here's a video of it working: https://photos.app.goo.gl/2Ji2LvgBHrhiGwH47 Does this violate Zaxcom's patent? Slightly related question: Would anyone buy this?
  4. Ah, so it just gives out what the 788t is getting into it on the hirose jack?

    Noisy R1a?

    It's cause you're using low impedance headphones. Put in a 220 ohm inline resistor like this one: https://www.amazon.com/gp/product/B07FMGTBBL/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 It will kill the noise floor. Then you put the volume higher to compensate for the resistor.
  6. Hey, I'm building a remote roll box for my 788t with some additional buttons on it, and was working on powering it. I noticed that pin #10 on the DE-15 says 10V DC in the manual. Is that an input or an output? It'd be cool to power the external box off one connector, but it seems suspiciously like it's an input.
  7. Hey guys, I'm going to start by saying that this is a very specific question and has no practical use on a film set. It's for a project I'm working on at home. The basic idea is one SMV transmitter with a lav going into it. Call the lav Source A. I need a second source of mic level audio, Source B, going into the same input jack on the transmitter. I would make an external circuit so that when there is signal present on Source B, Source A is muted and Source B is allowed to pass into the transmitter. I was planning on achieving the mic level of Source B by padding
  8. Hey Guys, I was looking into a way to interact with my 788T via a tablet or PC of some kind and there appears to be no really good option anymore. The CL-Wifi didn't work that great when I had one, and the app appears to be no longer supported on the app store. The Wave Agent control mode leaves a bit to be desired and isn't really meant to be used to control the machine/arm & disarm tracks, etc. I want to write an app to control my 788T via a mac desktop and the usb port on the 788T with the 788T set to Wave Agent Control Mode. I've written some mac s
  9. Hey Guys, Was wondering what the best blocks are for NYC nowadays. I used to have all block 26 stuff, but I hear now that it should be avoided. Thanks, Joe
  10. Hey Guys, Just starting to research the new SMWB transmitters and I'm wondering if I'm missing something in regards to the software on the transmitter itself and updating. Is what is available at this link: https://www.lectrosonics.com/Support/category/98-smwb-smdwb.html the software running on the transmitter (the OS) or is this something more low level than that? If so, are OS updates available to do yourself or do you have to send them in? Thanks
  11. Hey Guys, Got a bunch of COS-11's that didn't get wrapped properly last time I used them and they've been like that for a while. The cables are pretty wavy at this point. Any tips for straightening them back to the way they were? Thanks, Joe
  12. Hey Guys, Had a TS-3 come back from camera and they said something was rattling inside. I opened the battery door and this small black plastic piece pictured here fell out of the slate. It's currently rejammed and functioning normally as far as I can tell. (It was still jammed when I got it back. I had to rejam cause I turned it off.) Anyone have any idea what this piece is? Not sure on a scale of 1-10 how dire of a problem it is if we continue to use the slate or if it should be sent for immediate repair. Thanks! Joe
  13. Hey Guys, Thanks for the replies. The question was regarding running a mini mite with the 1/4 length antenna that's usually on the M-216, instead of using the much longer whip that comes with the mini-mite. I tried it out, and didn't notice much of a difference, though the tests I run in my apartment building rarely ever reflect real world applications. This setup was purely done as an experiment to save space/height on my cart. I'm going to try it out for a while and see how it goes range-wise. I'll keep you guys posted. Thanks, Joe
  14. Will this work? The large antenna for the Mini Mite is too big for my current setup. Being fed by a basestation. Just wanted to know if this would work better than just using the small whip by itself. Thanks, Joe
  15. Thanks for the reply. Good to know about the PCB change. That noise was the only finicky thing I heard about the 8xxx series and I'm glad they fixed it. Just to confirm: does the MZG swivel both ways, or only in one direction?
