Arduino project chat
having Neural cybernetics as a hobby of old, I was intruiged by this post:
quote:

Presently ( mainly for work at the mo, but have some ideas up my sleeve) , look at this stuff.
Its so versatile and cheap (£17 for the cheapest version)and the uses are only limited by the users imagination .
I have an ATU in the pipe line 
http://www.arduino.cc/
Enjoy, people
needless to say I did, and needless to say it`s what I`v been doing now for over 2 decades, and NO I`m Not trying to belittle it by that, but rather the opposite, I think it`s a Fantastic idea! 
and somewhat "About Time!".
I designed what I called the "G8" board, it was Z80 based and the bare bones basics of a fully working computer on a small 4x4 inch board, and it`s Original job was to expand the Zones on an alarm system.
the Arduinos and their many clones do everything these "G8"s did and more it would seem.
I can imagine the ATU project Easily being made an Auto-ATU with one of these inside with it`s analogue inputs for sensing and digital servo(s) out! or even relay switching (but I like the Idea of a Servo on a variable Cap shaft too).
it might make a nice home based Repeater project too, being able to control and use your Home radio with a handheld radio (a Wouxun for example)via the DTMF keypad.
the ideas are fairly limitless!

Re: Arduino project chat
Digital electronics are a bit out of my league I'm afraid - I still live in the age of the thermionic valve.

Andy nothing like a big Triode under your feet to keep your toes warm !
And they also double as a toaster.... hhhmmmm ..... toast

Im glad you like it.
Ive not been into code writing for long, have always been 'pure' electronics so thats why its a recent discovery for me.
Previously to finding the Arduino, i have done a few PIC based projects. The last one was a variable speed 3 phase tacho generator to simulate a motor for a project at work. It worked very well
There are so many things that can be done with these and their similar devices.
With the ATU , i was thinking of using varicap diodes instead of a mechanical set-up.
I have managed to save £1000s on projects at work using these devices.
As i go along, i can update people on here, if there is any particular interest.
Cheers chaps

Re: Arduino project chat
I absolutely agree on the Valve usage too, I much prefer them for many apps that require transistors and such, and they kick a$$ outa FETs/SCRs for turning mains powered Christmas tree light strings on/off
but I`m comfortable using Both technologies.
anyway, my DFRduino arrived a few days ago and I`v been having a mess about with different "Sketches" (why the HELL don`t they just call it a Program!???), and have also built a little "Sheild" (another unnecessary name for an Interface), and find it`s fairly easy to use.
the Programming language though...
well lets just say it leaves me with "language" of my own! 
it seems a step Backwards rather than when I left off about 15 years ago, I somewhat expected that a modern programing lang would be less Spastic.
not withstanding that, a Step learning curve latter and I expect some interesting results from this tech

Re: Arduino project chat
well I`m slowly progressing past making little Knight Rider lights on my vero board plugin, and have just bought a 7 servo robot arm made by Lynx.
it`s only the arm and servos, so I`v bought a servo controller board too, so that should free up the processor time on this little Atmega 328.
I know it can control the servos too, but that would only leave me about 50% cpu time, whereas I can have 100% if I "Talk" to the servo controller via the serial link.
I`m going to build a "Scutter" type robot as seen on Red Dwarf, give it a broom and teach it to sweep up the shack
I`m only Half kidding!
your Varicap diode idea would probably work for QRP, but these variable caps in larger ATUs need quite some plate spacing to prevent arcing, I`m not sure there are any variac diodes up to that kind of power.
I`d love to be wrong though.

Re: Arduino project chat
This is the code i did for testing a PSU with 5v,12v and 35v O/P and variable inputs between 110v and 240v. Ive split the code in to so i can post it on here. Some of the stuf is in there for debug use too.Its for Arduino Mega:

Re: Arduino project chat
Basically, it measures the 3 supply lines and passes or fails them according to the limits i set. It also passes and fails each input voltage section.The input voltages are supplied by an auto transformer and switched in/out by solid state relays and a contactor controlled by the Arduino.
The measured voltage can be observed through Hyperterminal and a series of 'Pass'/ 'Fail' leds.
