News update 2016-07-17The probe for Ph and ORP for Pool controller has been delivered. And iv start playing around with it. i use an Arduino Uno R3 to read the values. I actually i do no much programming/calculation at all, i did make a shortcut in the design and using Ph and ORP circuits from www.atlas-scientific.com.And the sensors are the same as from www.phidgets.com.I have also start looking into making a UV-C light cleaning unit for the pool, that will reduce the need for chlorine and might even reduce cost for running the pool environment during the summer month.
News update 2016-02-02As you all can se, nothing really happens on the site, as the result of work change two years ago there has been a lot less time over for private projects.This year i will try to reschedule my time and start traveling less and hope that i can find the strength to start new or perhaps push some of my earlier projects over the finish line.
So what are these projects
- Pool controller- Part 1 - This project is actually good for me personally in two ways, reducing cost and and development of skills * Automatic optimize water-flow thru the air/water heater for best performance ratio- Part 2 - add heat sources, sun-heater, district heating with goal to use the best economic heating resource at every moment. * Logging Temperature in Pool-water, Outside air, Active Sun hours and radiation to make optimization as good a possible. * Logging of Ph and ORP values to better help decide when it's time and the amount of chlorine to add the system.
- Arduino/Raspberry Pi CAN controllerJust a fun projects due i like things that communicates, and ill think this is a modern way of communication that will give me both a challenge and fun * CAN (like in OBD-II Port used i cars), a nice result would be a color-display showing different CAN-bus information. * CAN (like in NMEA2000 bus used primary used in boats).
- AIS receiver / decoderAs i see this, there is two ways using a fixed radio module receiving AIS-1/2 signals or trying to use SDR, there are a lot of projects out there and ill think ill start with two NRX1 fixed modules for AIS1/2 from (www.radiometrix.com) and a particle (www.particle.io) as the brain unit and see what it will bring to the table.
- PCB manufacturing and component reflowing.As it was many years ago since i last was sending projects to production (actually this has never been done privat, only in the profession i was at time) and today i see som many more options/possibilities today, and id would like to try these out, draw my own PCB and send for a test production and there after mount and reflow the boards. I have an ide that i might build a small test production reflow controller unit that will make future PCB projects possible.
