Re: Where to hire RPi experts?

I don't get what you are looking for: Are you looking for
1) someone to build a magic tool that turns a Pi running an arbitrary OS and your software into a graphic wonder ?
2) someone that builds a OS image that turns a Pi into a graphic wonder so that you can run run your software on it?

Re: Making: How to fill the gap

There is an autorouter for KiCAD (wrtitten in java) and I have used it on 2 or 3 projects when I leared KiCAD. In the end it was not worth the trouble: it generated bizzare pcbs, so all vias had to be changed by hand, so after some hours I kicked the autorouter. Problems with signal interfering star...

Re: Rasberry pi and virtualhere

my 2¢: Forget android. Install plain Linux on the Pi. Check, how you have access to the data from the console. If that works you have no problem at all, just send the data encrypted to your server and you are done.

Re: Rasberry pi and virtualhere

You most likely do not want a USB-over-internet-thingie. Question is, what do you want? Would be niche if you discribe what you have and how it wrks now, then what you would like to change, and at last how you would want to to the changes.

Re: looking for sw developper web based

So there's no real realtime, it's just one user sometimes opening his webbrowser to get some data? Why don't you just use ssh instead of the whole vpn voodoo, do what ever you want over ssh and maybe write a gui client for yourself that basicly does all the "lowlevel" ssh stuff?

Re: looking for sw developper web based

PRi == RPi with 2 letters swapped :)

So that I get it: you want a HTML page with one button that should turn on something? Usually you get an ESP8266 with arduino for ~ 2 bucks + some wirings and that's it.

Re: Looking for someone to write a program for me

That's no problem at all. For PWM use analogWrite(), for the rest you'll be happy with digitalRead() and digitalWrite(). For key debouncing use delay(50) just at the end of your loop().

EDIT: you mentioned 160ms. Use millis() to build that signal - or use the TimerOne library for that.
