Ryan,
The Aquarium site will be back in a week or so, Just finalising a new
Raspberrypi installation. I now have a really clean www directory and
cleaned up the html. The following ftp site has an older image however if
you wait 2 weeks I will post a new image of my www directory

Hi Mick,
Just wondering if the Rpi is reliable over longer periods. I have just set
mine up and worried about memory leaks. What is your greatest up time and
do you also run rrdtools and apache ?
I have I2C 1wire and a couple of serial devices I am communicating to
running the new Rpi Raspbian
Thanks for the update, I may update myself over the next few weeks. Owfs
seems very reliable on this platform with I2C.

Hi Roberto,
An industrial standard for converting 4-20mA is to use a precision 250 ohm
resistor in series with the circuit. This provides a 1-5VDC voltage drop
across the resistor which is proportional to 4-20mA. 250 ohm resistors are
expensive so I generally use 4 x 1k resistors in parallel.
Hi List,

You cannot connect an RTD sensor to two amplifiers. I would believe the easiest way to connect an RTD to 1 wire is using a RTD transmitter (see ebay). They are about $20.00 and run from 12-24VDC & provide 4-20ma signal proportional to the tempertaure. Placing a 250ohm resistor in series with the

I thought the counter was used with the "tipping bucket" type of rain detector
that measures rain fall for all weather station applications. I use it
connected to a flow meter that provides 4000 pulses per litre. The flow meter
