Re: Thoughts on using a Hybrid Automobile as a power system for cabin

7 hours 54 min ago
I spoke with Randy Bryant over at Converdant, the guy that sells these inverters, and also spent some time looking at the Prius. 

When used as a power system, the Prius will cycle the engine on and off as needed to maintain the propulsion battery pack...

Just got back from a nice visit to the cabin.  I learned a great deal.

1.  The Harbor Freight 45 watt solar panels did an excellent job keeping the batteries up to charge while I was gone.  When I arrived, after having been gone for 2 weeks, the batter...

Give it a try, you will learn a lot that way. I didn't want you to put a lot of effort into it and be disappointed.

If you can get some reasonable magnets in there on some form of iron core you will not struggle with volts.You will struggle with curren...

Well i guess ill do a little experimenting then with this motor. Doesn't hurt to try a few things before stepping into deeper waters =)

Anyways if i could make it to produce 15v max i would be happy.
Ill slap on some magnets read the output see whats ...

Hello all,  i received a quote for the c8 magnets from a recommended supplier for the 2f design.  This is in quantity but the price is 36 cents each before shipping.  I only received 1 quote at just under 4 dollars for 2x1x1/2 n42 nickel plated neos (i...

Still watching with interest.  Love the way this is turning out.
I don't actually have anything to add - except to Clockman, that round bale time has only just arrived here.

Clockman, thats a good looking result thus far... making me look bad

Had a 1 year old 5kw PJ turn up today with a   noisy transformer. It turned out to be one of the totem driver transistors causing the problem... it went short to ground, so the h b...

Most toroid winders do not use a spool type bobbin, they use a long flat form like a stretched H shape that fits through the core. Wind your wire on that and you don't have to twist the bobbin to go through the hole while winding.

Everyone,  thanks for the help so far.  Yes a plasma cutter would be nice and an older lincoln capable of doing the job but thinking to buy a hypertherm.  The model 65 would lead to a probable need for a generator to go with it.  A CNC table would be t...

I am not sure whether this is a commercial venture or a project to make a few efficient machines for producing power.

If a commercial venture the requirements are quite different and absolute efficiency will not get you a viable product you will have t...

Those 'Inserts' seem to be just smaller toroid cores, I think just to keep my big cores from deforming while in transit here.? Anyway they come in handy.

And yes oztules the 'beggers are heavy'.

Just finished the first winding/layer of 1.8mm diameter ...

product design is what is studied in school. what ever i learned about producing electricity i learned right here at otherpower listening to guys like flux, hiker, Hugh and the Dans.

you have to figure out your market.

Mon, 07/06/2015 - 05:30
I agree with the others, you can get something out of it and as an experiment to gain experience it may be fun. In reality it is unsuitable in many ways and would probably need to work on a 48v system to use the original winding.

The poor construction ...

Hi

If you want part of the load to be lighting then I would go for 12V LED. I have a camper and I stripped all the 12V flourescent lighting and fitted LED strip lights. I also have a roll of LEDs and you cut them into multiples of 3 and feed them with ...

Thanks Joe for the info, didn't really thought about that or read about it yet.
I've noticed the coils but wasn't quiet sure about the phases.

i did read on how to position and where the magnetic pole pieces should sit (i think it was zubbly's guide), ...
