I will be following this thread and hopefully we can get a schematic. I want one! I see a voltage regulator, some diodes, resistors, capacitor, looks like maybe a crystal over to the right corner. Not sure what the IC is. But this is a start. And no I am not smart enough to make sense of what they do. I can build though.
I will build one or two
If I can get a schematic or one of the more electronic engineer endowed folks could figure out what they did.
Even add a potentiometer somewhere where the skew could be adjusted a bit in either switched mode.
these pics came from a site called Sat industry forums.
I think they do some hacking as I seen a section for "files" "keys".
Get past that stuff and this is on there. I thought about registering to send a pm to the guy who made this.

I was thinking about a pot as well for fine tuning...I think this would be a must. I will check the site out. I always wondered why the vbox (which I don't own yet) doesn't have a skew controller on it. They need a bud version.
Truckracer if you are looking to build something, I once had a c-band feedhorn with a polarotor1 on it (no feedback-just voltage only, reversed the voltage to switch H to V etc) When the receiver I had quit moving it, a very early model I forget which, I went to radioshack and bought a toggle-switch, and put a 9volt battery inside the metal box I mounted it on. Hooked up wires to it all from the feedhorn, and just pushed left or right on the switch to change polarity lol. Crude but it worked until I got a new feedhorn and better receiver.
I was looking to build something more automatic and transparent. Just flip the remote control channels and coax voltage would convert to 5v pulses to change polarity.
I can certainly see where the voltage controlled lnbf's are an asset. I just wish my bsc-621 did better on ku.

I know where your coming from with making it automatic. When I put up my primestar dish it has the stock LNB so it feed V & H on 2 coax's. When pointed at X4 I originally had a to get up and switch a manual switch for V & H. Due to logic issues on the 4DTV it will not accept a polorotor and & LNBF at the same time. I ended up getting an old coax relay from 1989 that had a a 0/5 volt state. The trick was to interface it to the 4D for automatic operation. Using the unknown port next to the polorotor connections on the 4D that can contol a V/H logic state I built a logic switch with a transistor, relay, voltage regulator and a few support parts. That did what I wanted. I kept doing research & experimenting till I came up with what I wanted. So keep on keeping on... and something will turn up for what you want.
I know this is very do-able. Once I did see an old servo switch that did what I want. I think a few of the other members on the board would benefit from this type of device. I emailed DMS international and ask them for a solution. I asked them to incorporate this function in the next V-box.
They created 1/2 the solution to interface new school (FTA diseqc) to old school (actuator arms).
Now we need them to build this into their new v-box.
Imagine even having the v-box remote with a skew buttons! I am still looking
