project completed
Well, seven months after the initial post, and with the welcome assistance from DT to develop the code, the hardware has finally been completed and tested. All that remains is to remove the old commercial ON/OFF stats and hook the heaters and light up to this new unit.
I might look at having some PCB's made up as I've been asked if I could build a unit by other reptile keepers... and who knows, there may even be a market for such a device....

Hi Malc long time no speaky hehehe....
Love the project! very nice bit of kit you guys have developed there!
Been updating my bits and bobs so that I can start developing some bits for my small reef tank etc and cant wait as along with the usual temp reader, im also looking at adding water level detectors (going to try sonic sensors as got a few laying about) and when funds allow, will be having a go at using the larger powered LED's to make a new light unit where i can control dawn to dusk etc (thing with LED's are the large amounts of them you need for penetration/cover on a reef tank)
If I can get anything that remotely resembles the quality bit of kit you created i'll be a very happy chappy
Mark.

Hi mate,
I'm sure if you could encapsulate the DS18B20's in some form of heat shrink boot you could use this project to control heaters in up to 4 tanks, and with the DS1307 and a bit of adaptation program seasons with shortening / lengthening days to switch in those lights.
The version of the code I'm now working on is so far advanced than that listed here, but what is listed can be used as a base if you wish.

Might have a look through the code as I'm rather rusty lol. But hoping to write most of it myself to dust off the cobwebs and it's also a good way to fully understand what's going on etc. But might end up still asking a few q's etc which is why this forum is cool as so many pol willing to help etc.

PCB's
Well I received 6 PCB's that I had made by PCBWing in Hong Kong, which I must say offer a fantastic quick service even on the "economy" option. I chose the 7 day turn-around, and the boards were received around 12 days after placing the order.
Here's the 1st board, not quite completed, but you can see the quality of the PCB. I'm hoping to get the first "production" unit complete in the next couple of weeks, funds permitting. I've already had people on the reptile forum dropping me PM's with offers to purchase it... - Just need to resolve the coms issue in the firmware first !

Excelent Work! Congratulations!
