Good morning - I haev another thread that is being greatly helped by this forum and i really appreciate the help i get. because this place is so great i thought i would ask for help with a problem at work.
We haev a NOISY factory floor, on which i have put two phones to save me walking down...
Kinda update and questions.......
Firstly i took off a switch and - well that was confusing.... It has a part that links two pins, then when you press the switch down it connects a different pair of pins whilst also having an arm that moves sideways to connect something else..... I just should...
How about..
1. I tape down (somehow) the buttons
2. I break the track from battery to the switch(s)
3. I use the opto coupler thing to re-make the track and hence turn on the switch
this is not an ideal answer for me but will it work? Obviously the best solution would be a way without the...
Right - Its really hard to read the writing on that chip.. but this is what it says (i am 99% sure)

ANy help???
Its me again....
Firstly - i have managed to take some pictures - will upload them later on. You can see the tracks a bit more clearly on these so.. Wait and see the clarity.
Anyway - Steve - I tested the Resistance and got 1M ohms on most until the button was pressed then that dropped to...
pretty pore i know.
if you look at it with the battery at at the bottom of the pic then the 2 buttons on the left,the top one is OPEN and the lower one is CLOSE, as you will see there is another on the right which is a STOP button,dont know wether this helps or not.
UPDATE!!
News not good... not all bad but not good.
Anyway - I made up the circuit first. before soldering to any part of the remote i thought i would use it to turn on a simple LED. I connected up an led accross a 12V supply to ensure it worked. i then used the 'Optocoupler' to turn it on...
Well thanks for all your help - i have sourced the parts from RS (i hope).. Am going to try and make it this week. Will keep you informed.
As for antennas - SIMPLE really compared to this black magic. Normally cut a piece of metal to a half wave - which is 150000/freq in MHz - then stick some...
Thats GREAT - Thanks! ... The standard supplier i use at my work for antenna components is RS (rswww.com) i have the Resistirs / capacitors all here.. its just the opto-coupler item that i am unsure of purchasing... I have a MAPLIN near me. Oh and my sense of humour comes about when i am...
I thought the remote type would not matter but just had to check. Being honest I have ZERO experience of opto-couplers and can't quite fathom out your very simple idea. Guess my electronics knowledge is worse than most... If you could walka complete novice through the layout I would be...
Hi Resqueline
thancks for the reply.
Dont mean to be a pain but i forgot to mention that the remote for the electric curtains is RF does this make any difference?.
Hello,
Background on me - i work as an antenna designer - so have access to some SIMPLE electronics - and i mean simple....
Issue - a colleague has a work lagre TV screen set up with 'curtain' that opens up via remote control. press once to open (you cant hold the button down) press...
