Dude, good work!! If remember correctly the ELC of the great Manfred (ludens.cl) did not rely on Hummingbird protection features. His ultimate goal was to create a PWM ELC.
Do you think we could tackle it - or do you use the same circuit like the ELC of ludens.columbia?
I see many people think of the Hummingbird Design of Jan as an unstable one -- I always wonder if it's not stable with loads of dump loads. Can we get rid of harmonics and distortions this way?
Nevertheless good work! It's been time for our blue Open source planet to include a reference design for digital micro hydro with protection features.
Do you know opensourceecology.de? I'm involved there, too. opensourceecology is brilliant and the most advanced project of earth's citizens I know of - biggest part is that we gather our people as they otherwise would just introduce too much redundancy, nothing against redundancy, but I think of it as a waste of time in software like freeCAD or libreCAD, these projects should be joined with blender I'm convinced. Data masses are a huge problem anyway, so let's put it all to opensourceecology. It's a physicist who started this movement after his studies, Marcin Jakubowski - opensourceecology.org. Their plans are incredible: Aluminium Extractur, Induction furnace, open clothes, open chemistry, open steam engine designs, 3D printer even for metal!! Simply brilliant!! This is a bright future (if we can get rid of war)!
>Do you think we could tackle it - or do you use the same circuit like the ELC >of ludens.columbia? Yes, I think we can tackle it. I use a more extended circuit. But it's not ready for sharing yet. At the moment, the ELC project has to wait a little because the hydro power site I am involved in has functioning ELCs. They use a system called powerpal from New Zealand, but apparently this system is not produced anymore - at least the website has gone down. Currently I'm working on a prepaid electric meter system, which has to be finished in fall 2013.

Thank you for your interest! Be assured, the ELC project is not dead, but it will take another few months before I will pick it up again. Thomas

Correction, I mixed something up here. The system is called powerflow. The website www.powerflow.co.nz is out-dated, but the product is continued here: http://fastec.co.nz/fastec-powerflow/#powerflow An old manual can be found here: http://www.planetarypower.com.au/info/microhydro/Powerflow_ELG_Manual.pdf
www.powerpal.co.uk is a british hydro power company. www.powerpal.com apparently sells the same turbines.
Thank you very much for your answers! It's a pity that you have no time for the ELC, I know that problem.
I will hopefully gain more experience in the upcoming months and perhaps have the chance to test the hummingbird or perhaps go for the ludens ELC despite of the missing protection features. If I remember correctly Jan Portegjis' Hummingbird did not have these protection features either in the beginning.
Perhaps I can contribute myself then later too. Am still happy you put up this site to share your work!
Keep going and good luck for the meter - a very important circuitry, so much depends on it (I think of proper control relying on badly measured voltages, frequencies and currents, what a desaster that would/could be).
