Hi,

Before you move too far forward with this, you may wish to reconsider the circuit. You only have only one current limiting resistor on the LEDs. The current across this will vary according to the combination or R/G/B you have illuminated. You really need to have one resistor per LED colour and not per LED combination.

I have sent you a PM for creating a PCB from your fritzing files. BTW what arduino are you using for the shield footprint.


Cheers Pete.

Hi Nishant,

If you had taken the time to read my post it said to reply to the forum or my personal email. You responded with a PM. I presumed this was a mistake on you part and you where intending to reply to the forum. I therefore corrected this. If this has cause you  any problems then I apologise.

A wise man once told me that when no offense is intended then only a fool would be offended. I intended you no offense, and since i know you are not a fool i can assume that you have taken none.

Now since we are going to be working on a project together I suggest that we stop "puffing our chests" and start collaborating in a way that is beneficial for our mutual client.

I have resolved the problem of the GPRS code, another developer kindly offered to test it for me for free.

Cheers Pete.

Hi Peter,

I can do it ,I'll take 500USD for it out of which 300USD would be advance.
I have already done a lot of HTTP POST using a GPRS SIM300 and 900 GSM modules , In one project I have used the data to be uploaded to my website and show in good beautiful graph >> http://winacro.com/index.php/playingprojects

Hi Nishant,

thank you for this offer but $500 to test a piece of code I have already written but don't have GPRS  coverage to work with  is just a little too much. If I was asking you to create an application from scratch then this would be about right. Don't forget I am a developer just like you and know how long it takes to do these things about 2 hours I think, less if you intend to re-cycle some code you have already use before.

Cheers Pete.

Hello Folks,

I am in need of some code to send a POST to a server with some data in it and return the response from the server.

The code will be running on an Arduino UNO ATMEGA328. Memory is already in short supply and so it would be great if you could not increase the memory (RAM) footprint.

I will have the address of the server in a char array along with the password and other configuration data like port etc.

I am willing to pay to test this code and get it working if someone can get it to me withing the next few days. I would normally write and test this myself but i don't have GPRS coverage here in the little village I live in in the South of France and so I am writing blind with no testing

I have begun writing this in the structure i would like to have it running it so if you want to take my code and make it work that may be quicker that starting from a blank sheet.


I have a USB->serial bridge attached to pins 2/3 as a debug port so I can see what is happening and the shield connected to the hardware Serial port. You can swap them about if you like for testing.

The code I have started is attached for reference. It was too big to include in the post

You can reply here in the list or drop me an email to my personal email address Peter(at)EmbededAT.com

Cheers Pete.

No so difficult to create a reasonably good UI with touch interface.

Here is what i eventual did for the client in about 2 days including the Mod bus interface.

Cheers Pete

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

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

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

and these

Have you tried using the TinyGPS Library.

I have attached it for your convenience


Cheers Pete.

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

A freebie would still be nice though

Cheers Pete.

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.
