Hi,
Brother who lives in a country town in Victoria, Australia, has to rely on electric hot water, (came with the  house when he bought  it).

It died about 6 months ago and he purchased one of these heatpump type hotwater heaters.

After 6months of winter conditions, (daytime winter average max not lower than 12C, nighttime -1C to 4C) he says its one of the best things he has done.
Power costs down, he is downloading an analysis of his power usage to get a better idea of how much.

He heats the house with good old wood and recycle-aircond.

Whats the BTUs? it would take about 180,000BTU (wood) to heat this house. ;)

People used to bank houses when winter didn't thaw till spring.
Now houses like yours need a different version of winter coat.

Jeez. Where are you? Alaska? Finland?

Two or three hours spent thinking and reading documentation solves most programming problems.

I only thought of Canada after I had posted Reply #1701 - sorry.

I spent a few very enjoyable days in Banff several years ago, followed by an unforgettable cab ride from there to Kamloops in a freight train.

Same place I got the 12V 5A Switching PS
http://www.ebay.com/itm/151002940216

I now have 2 5V 6A versions of the same enclosure and screw terminals. And adjustment screw pot(?) differs from the 12V.

Finally got some WS2812 strips.

I have to hand it to those cheap caged PSU's.
Mine have been on for over 9 months and never switched off apart from the odd short grid failure.

24V, 12V and a 5V hidden inside the test bed.
I do have a tiny fan raped from a graphics card on a small grille though. Not much CFM but seems to be enough.

I checked them for output and left them set.

Then just used some Chinese regulator boards with displays for adjustments outside the test bed.

It may not be the answer you were looking for but its the one I am giving based on either experience, educated guess, google or the fact that you gave nothing to go with in the first place so I used my wonky crystal ball.

Hi.
Altronics Catalog and next edition of new electronics mag DIYODE.


The magazine is new, so we now have 2 electronics magazines, the other SILICON CHIP.
They are not clones of each other which is good, each has different approach and level of project and presentation.

Trouble is they both appear on the newsagent shelves within a week of each other, I get them put away and pick them up in different pay weeks.

I got a bunch of FETs to be able to switch Amps through lots of leds and then I find that the strips I like don't need em!

I live in Arizona, what is a furnace?
I'm not disparaging the differently abled. It's just that thirty years of community college has literally made me mentally retarded.

Electric supercharger (eBay)



ok, so i haven't purchased this, but the thought of having a supercharger in my 2014 Chevy Spark (1.2L engine) is highly amusing. ;)

I missed the bit about the 1.2L engine when I first saw your Post.

You would probably get better performance just by gluing the fan to the roof and using it for direct propulsion. :)


I always thought 1.2L engines in the USA were just used as starter motors.

I've worked on V-12 engines with a single cylinder larger than that.
