Skip,
I'm working on an Arduino based system that will put everything up on one or two
2.8" touch screens - I am squeezing this into a Long EZ so space is a premium.
It'll replace my tach and EOP/EOT gauges as far as location.
It'll do full engine monitoring (put some of the commercial systems to shame),
air data, economy and performance, and a handful of other things while I'm at
it. I'm a bit of an engine geek and learning the electronics side of it.
If you'd like to learn more, I'm more than willing to share what I'm doing...

I think the Samsung 5 phone has the better amoled screen. What screen
type does your tablet have?

In my RV-10 I installed 2 (computer type) cooler fans in the dashboard, with the
main purpose of cooling the atmosphere behind the instrument panel to keep all
the panel electronics happy.
Those 2 fans get power through a thermostat, whose temperatures (to turn the fans
on and off) can be set.
Further to this electronics cooling function, and copying other fellow builders
idea, this fans may also be used to defrost the windshield interior surface.
But for this defrost function, I want to be able to turn On the fans independently
of the thermostat, so I decided to put a switch for this.
Now comes the question: how do I wire this switch in relation with the thermostat
circuit?
Do I have to use a diode?
Thanks in advance
Carlos

Carlos,
Just wire the thermostat switch and the defrost switch in parallel.
When the electronics temperature is high the thermostat will turn on the
fan, no matter the position of the defrost switch. Also if you turn on
the defrost switch the fan will stay on until you turn it off. If you
have two switches in parallel, either one or both on will power up the
fan.

A simple bimetal switch is all you need as a thermostat. It consists of a
bimetal strip which deforms as it is heated and closes the switch contacts.
I am not aware of any thermostat that would be harmed by paralleling it w
ith a switch. What thermostat are you using?

So the question that is begged is what will blowing ambient air on a frosted
windscreen do. In your car the defrosted air is heated additionally the air
conditioner compressor is activated (temperature permitting) to reduce mois
ture. Your body is constantly creating moisture ( primarily through respirat
ion and sweating) this condenses on the inside of your windscreen under cert
ain conditions. Unheated blown air will have little effect. It will have les
s effect on ice on the outside. Perhaps a small electric heater will help.

Now comes the question: how do I wire this switch in relation with the
thermostat circuit?
Do I have to use a diode?
Thanks in advance

Subject: | Re: Defrost switch |
At the other end of the spectrum, I live in Canada, and did several flights this
winter with temperatures in the -25C to -30C range. I have the same configuration
- just a couple of computer fans mounted in the glare shield, whose purpose
is to blow air from behind the instrument panel, where the air is heated
from the instruments and cabin heat output by the feet.
I can say that at least in my case, it's worked perfectly. If the cabin is kept
reasonably warm through cabin heat, which is what you'd want to do anyway, it
doesn't have any problem keeping the windshield clear in my RV10. The only
case where heated blown air might have helped is during runup and initial taxi
before the engine has gotten warm enough to heat things up sufficiently. But
when underway, the windshield has remained perfectly clear (not the same to be
said of the side windows that didn't have the fans blowing on them - they tend
to get quite icy in those conditions).
One thing working in my favour is our winters are typically exceptionally dry,
so the humidity of the air is very low - with the exception of the humidity generated
by the occupants.

compressor is activated (temperature permitting) to reduce moisture.
Your body is constantly creating moisture ( primarily through respiration and
sweating) this condenses on the inside of your windscreen under certain conditions.
Unheated blown air will have little effect. It will have less effect on
ice on the outside. Perhaps a small electric heater will help.

the fan will stay on until you turn it off. If you have two switches in parallel,
either one or both on will power up the fan.
