Hey Guys.
I have been inspired by NSteyn's link on the DIY controller to start a project for a DIY controller. At first I'd like to start with a basic reading/reporting controller:
1. temp
2. pH
3. Saliinity
I think this can be done pretty cheaply and could be a lot of fun. I am a programmer by profession so I am happy to work on it with others on the forum. I have experience programming PIC micros and LCDs (built a tachometer for my RC helicopter).
p.s. just as an indicator of pricing. A pretty decent pic micro will set you back R30, a 16X2 LCD about R60, LM35 temp sensor about R20. So as a start thats a digital Temp display for just over R100 - then you can add circuits for pH, salinity, etc. of course here you would only pay incremental components as the micro and LCD will stay the same for all the additions.
Any ideas, other parties interested?
Cheers
Jason
