The power supply of SIM900 is from single voltage source of VBAT= 3.4V TO 4.5V. In some case, the ripple in a transmitting burst may  cause voltage drops when current consumptions rises to typical peaks of 2A. So the power supply must be able to provide sufficient current up to 2A.

Yes, that is correct. The peaks are of brief duration but unless the supply has sufficient capacity you can have intermittent problems.

I'm finding that in the UK. They are shipping the stuff in bulk then distributing it from a UK address.

Obviously they think you Antipodeans have more money than sense. But I love the way the Australian flag is scattered amongst the illustrations, appealing to your patriotism. Apart from the fact that the advert is typical of the China based operations.

Google Zambretti - there's an online weather forecaster that might yield useful information!

Please list the exact error(s) you are getting?

The OP has two choices with the AT commands. One is to wait until the modem sends back the OK confirmation, or take the easy way and use delay() which assumes you will get the OK back within that time. The modem won't respond to a second AT command until it has processed the first and returned the OK.

OP, try reducing the delay to 100, and if you have problems increase it by 50 at a time. Or wait until the modem has responded with the OK.

Do a search - I've seen something like this before. It used a stepper motor to move the glass between the bottles and it was raised to dispense the liquid by an optic.

I recall that there was a thread on this subject some time ago. If you do a search it might yield some material of interest.

Does anyone have any experience of decoding the Honeywell HCW80 wireless thermostat, or similar?

I know they operate at 868 Mhz but at the moment that's as far as I've got!

They are. And the bus address is the same.

However, the 1302 has an additional flag to indicate whether or not the clock is halted.

If you want to pay someone to write the code for you, you need to be over at Gigs and Collaborations. Otherwise please post the code you have along with details of the hardware you are using and how it is connected together.
103  Using Arduino / Project Guidance / Re: Sim900 GSM Shield Problem on: June 21, 2014, 08:03:46 am
I think that you can get a GSM library so you don't have to use AT commands, but I don't understand why you wouldn't want to use them in the first place?
104  Using Arduino / Networking, Protocols, and Devices / Re: Problem with gsm module simcom SIM900 ?? on: June 20, 2014, 02:49:49 am
Could you post a link to the SIM900 device you are trying to use?

I used to make my own capacitors by filing down coins for the silver content
