Ok why rs232 and not rs485, you will be needing a multi drop bus for all the Nanos onto a single UNO

Are they (Nanos) responsible for triggering the lock , the LED and reading the RFID . I guess you are sending a data packet from the nanos to the UNO with the door ID and the RFID tag ID. Then expecting a response frm the NANO with a allow or deny door open command as the basic functionality

I am sure this is easily done it just needs to be broken into small manageable packets of work.

PM me if you need more help or ask it here in the thread

Cheers Pete.

None of these are live or have been filled already possibly with the exception of the genius requirement. For that i posed the question about sanity levels as I possible fall into the category of "MAD" genius. I await a reply smiley

I can do it too if you want to go to France and I have a China supplier that is NOT closed for the New year smiley

that not bad at all I use an outfit on Ebay

http://www.ebay.co.uk/itm/350610605051?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649

They do a good offer and they have fast shipping too if you need it. I have had boards turned around in 7 working days including shipping to the France for an extra $15 shipping

Cheers Pete

HI Mike,

         a lot of us here in this section of the forum offer the same services. I can be found at www.EmbeddedAT.com. I don't suppose you would like to share your PCB fabrication contacts with us would you. I currently use some Far Eastern fabricators for both up to  5 Prototype boards and over 100 units.

Cheers Pete.

Or if like me you are trying to keep costs down build it into your PCB using these

http://www.ebay.co.uk/itm/170798024540?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649

Have you tried using the TinyGPS Library.

I have attached it for your convenience

OK I just gave in to temptation and pre-ordered one order #969001636.

A freebie would still be nice though smiley

there a pile on my desk waiting for programming and testing.

Since you are trying to enlist our help in supporting this new venture, perhaps some of those piles can make their way to interested developers to work with pro bona. There is nothing like a new toy to enthuse interest especially if you have one yourself to play with. I may be interested in helping since some of my clients already use solutions I have developed around the XRF.

Cheers Pete.

Hello Benjamin,

I don't live in London but I am currently working with a few artists and costume designers to create interactive pieces. I also have small scale assembly facilities in my workshop.

I have sent you a PM with my past projects and skills.

Drop me an email to my personal account (in the PM) if I can help.


Cheers Pete.

Hello,

        Thanks for the PM.

        OK like i have already said I need more information. There are parts of your requirement missing. Pitch of thread and deg of rotation per step are not really of a great deal of relevance to the way you want to program the system in terms of the user interface with the LCD and the 4x4 keyboard. from the information you have supplied all I can work out is that there are 100 steps per mm but you already know that.

I need to know what hardware you have

  • what motor do you have
  • what stepper motor driver do you have
  • what LCD module do you have and its interface I.E. UART/SPI/parralel
  • what 4x4 keypad do you have
  • what Arduino variant do you have

in addition i need to know your time scale expectations

Once I have all of this information then I can start to give you an idea of development costs.

Cheers Pete.

One option to overcome the shortage of PWM pins is to use the soft PWM library

http://code.google.com/p/rogue-code/wiki/SoftPWMLibraryDocumentation

I use this for LED driving where timing is not critical.

If teleworking is not a problem for you I have already built systems very much like yours for other clients. I have sent you a PM with my details and past projects. If I can help let me know.

Cheers Pete.

Some more information on the User Interface would be good a 4x4 keyboard it a bit open considering the you want the values to be absolute or relative, you need a way to select this using the interface.

Are yo expecting the "steps" of the motor to give you a position based on a fixed calibration point, can the movement be actuated manually, if so then the "step" counter will be out. An encoder wheel on the drive shaft is a better option or a stepper motor with a built in encoder wheel.

I have sent you a PM with some of my other work listed. If I can be of some help please drop me a PM or send to my personal email .

Cheers Pete.

I'll take your money  smiley-lol

Seriously though like Paul said. Why not learn how to do it.

I mean what use are you going to be to an employer designing stuff if all you ever do is buy the design from someone else. They could do that themselves and cut out the middle man.


For the Audio use one of these VS1000 Audio Module http://www.vlsi.fi/en/products/vs1000module.html only $20 and the cost of an uSD card and all programmable using serial commands through the serial port with a nice 5v power rail and TTL level UART

Cheers Pete.
