Re: Has anyone hacked or examined schematics for Inverter/Generator?

22 min 59 sec ago
Way back I glommed onto a Eu3000 shop manual with the point to point troubleshooting procedures just for the curiosity of  investigating multi-purpose inverter built in/around a Honda inverter generator...

If you need more logic options, controlling this buck converter can be done with a UNO.
I used the PWM output of pin #5 because it is at a higher frequency of 960Hz which makes
it easier to filter. This pin feeds a 750 ohm resistor to a 220uF cap which...

I've been looking for one of these inverter generators for a while with a defective inverter.  I just imagine they use some hybrid parts that make them uneconomical to repair after they are out of warranty. I would then just use the  DC power and feed ...

Re: DIY Air resistive loads?

Don't forget about aluminium clad resistors, available from e-bay.
The Chinese ones are not now that expensive, and available rated to several hundred watts.
Main advantage is you can get pretty close to any resistance value you need, or can get even c...

i actually used them as resistors once.

a 22mOhm mosfet is cheaper than a 22mOhm resistor in the same TO-220 heatsinkable package. the application i needed did not care about thermal coefficient, which as you know for silicon varies by an order of mag...

I know this is not exactly what the topic requested, but why not use MOSFET's as the Dump Load Resistors.  They are cheaper.  You can get a couple of 300W MOSFETs for around $5.  They would need to be mounted on heat sinks.  The bigger the heat sink, t...

Nice location! Bet the hunting is awesome. Propane is a pain below -20f. I rented a farmhouse with a propane furnace and several times I had to heat the regulator with a hair dryer to get things flowing when it dropped to -27 that winter. Only rented t...

I have never seen this anywhere else either, but its an excellent idea.

Doing it all at high dc voltage and low current means the efficiency will be very high.

I am doing something similar with a mains transformer rectifier, to generate a high dc volta...

This is an excellent idea, and a great writeup by Opera House.
A great deal of thought has obviously gone into developing this circuit.

I have been using a similar method of control in my own home built solar controller, although my own circuit is very...

i had full intentions of recording a bunch of videos on how all the different systems  functioned at the cabin last weekend.  But it was the first night with the new propane stove in the addition. The regulator froze up.  And killed my motivation.  Lol...

My son had a pallet load ( 130 panels )shipped from Miami to Idaho, turned out to be $6 ea. There is a minimum $2.50 ea shipping to get them from wherever to Miami for distribution. Only saw one with broken glass, a little dinged up and scuffed from be...

Waiting to see the energy side.  Best fire starter ever is shredded paper (those one inch crinkled types) mixed in a tub of melted candle wax. Long slow burn that starts even damp wood.

   Low Cost Power Point Controller, Linear Current Booster

This is an update on the simple Power Point controller proposed a few years ago. Using this
300W 40V 8A ebay buck converter, a decent 5A charge controller can be built suitable for small
appli...

Bought that old Findlay 2 years ago for $400 in decent shape.   Despite Their history they are not that great for cooking or heating.  It's a lot of work to keep the oven up to temp. But a lot of fun as well.

That lovely wood stove remains me of going to grandma's. Those make great coffee!
Thanks for sharing.

Been a little while since I've posted on here. I've asked a bunch of questions over the years on here. Thought maybe it was time I made a little video tour of the place.  It's my cabin in Ontario Canada. It's been a labor of love. A lot of the infrastr...
