paulears Posted September 6, 2008 Share Posted September 6, 2008 er.... stuart? the little circles labelled 1,2,3 are the chassis socket pins - the centre section is an XLR cable, with the other side having the opposite sex connector. I practice, you'd build this in two boxes, using an XLR fitted cable to connect the two. If you have never taken apart an XLR plug - this project might be a bit tough - as it involves a bit of soldering, some hole punching and wiring. You ok with this?

stuartm Posted September 6, 2008 Author Share Posted September 6, 2008 Ahh so my good idea was a stolen one! I can do soldering, hole-punching, wiring I have done PCB's just never actually tried with XLR - you never try, you never learn though Link to comment Share on other sites More sharing options...
revbobuk Posted September 6, 2008 Share Posted September 6, 2008 Just decided to pinch the idea, and knocked one of these up myself this afternoon. One alteration - I decided I'd rather have the resistor in the box with the battery, so that a fault in the cable doesn't leave the battery seeing a short circuit. And I know the real thing isn't exactly expensive, but this does also serve as a rudimentary cable tester for an XLR lead! The idea of a second (push to break) switch to flash an acknowledge is very neat. Link to comment Share on other sites More sharing options...

revbobuk Posted September 7, 2008 Share Posted September 7, 2008 Pictures? Here you go - haven't got to work with the label maker yet. http://lh3.ggpht.com/revbobuk/SMPg8rYhR6I/AAAAAAAABw0/uJdFwzK5d8Y/s144/IMG_2310.JPG Link to comment Share on other sites More sharing options...

adam2 Posted September 10, 2008 Share Posted September 10, 2008 To the above suggestions, I would add, use good bright wide angle LEDs , some cheaper types are only visable over quite a narrow angle, and hardly visable at all in well lit conditions.

Neil Hampson Posted September 10, 2008 Share Posted September 10, 2008 Looking at that I want one...I wonder where Zero88 get the 'Go' button from for the Jester, as that would do the Standby, Go and Acknowledge in one nice big button. Link to comment Share on other sites More sharing options...
revbobuk Posted September 10, 2008 Share Posted September 10, 2008 Having finished one of these (and I agree about the choice of LED comments above) I would with hindsight have done it slightly differently. Instead of using a switch on the sender for each LED, I would use a switch that is 3 position, centre off, latch in one direction, momentary in the other (Maplin FH02C) at the sender end. So flip the switch to the latched position (orange LED comes on), wait for the blink to acknowledge, then flip to the latching 'go' position (orange LED off, green LED comes on till you let go). And I'd not bother with the 'blink' switch on the 'go' LED. Makes the whole thing even simpler. Link to comment Share on other sites More sharing options...
