<div dir="ltr"><br><div class="gmail_extra">oh well thats my job.. ie showing people new shit.. (</div><div class="gmail_extra">btw I did find a usb -> 429 thing but didn't bookmark it..</div><div class="gmail_extra">
Now upwards.. on to my favorite subjects 'what you wanted to know but where afraid to ask' LOL I did a college paper on the math to drive a synchro the easy way.. piece of cake..</div><div class="gmail_extra">1. synchro review (quick I promise) as you know you put 400hz on the cotrol windings of a Tx and a Rx synchro's and then you attach a - a, b - b, and c - c right? so if you move the Tx the Rx will follow... all good so far?</div>
<div class="gmail_extra">2. question. if you put 400hz(ref) on a, and then 400hz(+120d) on b, and then 400hz(+240d) on c what would you need to move the pointer to 120d or 240d on the control windings.. </div><div class="gmail_extra">
<br></div><div class="gmail_extra">If you can give me the right answer on Saturday afternoon (as I have a day off today) and no guessing.. <br>
I will tell you why and how it works I might even right about it on my element14 blog LOL</div><div class="gmail_extra">enjoy the puzzle.... LOL<img src="cid:360@goomoji.gmail" style="margin: 0px 0.2ex; vertical-align: middle;" goomoji="360"></div>

See Cris, here's the problem with you, you keep introducing me to all these cool new boards that I then begin to want to go out and buy. :P I haven't even fired up my Raspberry Pi! Anyways, Himar at V1 told me something similar. They actually started with Arduino, but decided an FPGA solution would provide better performance, scalability, and better signal forming. Like I said, I did find someone who has done it, so I will probably follow their lead just so I can understand exactly how it works, but the V1 box will probably be my final solution...plenty of other stuff to busy myself with!<br>
<br>
My summer sim project will be synchros....I *think* I have a pretty good idea on how to read as well as drive most synchros, which will open up a lot of possibilities for older hardware.<br>
<br>
Thanks for the link though...more 429 gold! I will understand this stuff yet. :)<br>
