Ideas for resources you would like on this site
Wolvenar:
I have (very slowly) been working on building up some helpful web apps/calcs etc.
I am looking for ideas for what would be the most valuable things we would use here.
A few ideas of mine are a wire loss calc , metric converter, solar calc..
It would help if you have any links to such that is freely (legitly) usable.
Rover:
Wolv,
Just a thought, but if you put some home grown stuff, or links to others. Might be nice to place them not in a thread, but rather have them as static links.
Yep just a static old fashioned web page.

philb:
I'd like to see the apps or static links be controlled by admins that reside here.
Common stuff we can use regularly like ohms law, wire loss, ampacity charts, NEC wire run stuff etc. all would be very handy.
It would be easier to point newbies and us forgetful older folks to them if they were local to the site.
Some charts like this would be helpful http://www.windsun.com/Hardware/Wire_Table.htm
I'll have more time this weekend.
BTW, I've enjoyed 'My Bookmarks' you added.

Or, since we have a quick one-click link to IRC, we could invite them in there.
RossBot already does most of these things, and the icing on the cake is there is usually someone in IRC who can talk to them about what they want to do and perhaps avoid some of the common mistakes.
(Dare I say, things like measuring the distance between PV and batteries, calculating voltage drop - but forgetting to DOUBLE the distance for 2 runs!!)
The 'bot instantly solves a good many questions that are commonly asked - eg:
What series resistor and power do I need for a LED running on 24V at 12mA?
<RossW> !ohmslaw 12ma 24v
<RossBot> 24.000 volts at 12.000 milliamps through 2.000 kilohms for 288.000 milliwatts
How much resistance does 10 AWG wire have?
<RossW> !awg 10
<RossBot> 10 AWG wire is 0.008155 square inches (5.261167 square mm, 2.588191mm dia), 3.189406 ohms per Km Cu (5.046409 Al)
What is 16 sq mm wire in AWG?
<RossW> !2awg 16
<RossBot> 16.000000 sq mm (0.024800 sq inch) wire is 5 AWG, 1.048750 ohms per Km Cu (1.659375 Al)
How far is 3.75 metres in imperial, or 2' 8" in metric?
<RossW> !m 3.75
<RossBot> 3.75 m is 12 feet 3.60 inches
<RossW> !ft 2 8
<RossBot> 2 feet 8.0 inches is 0.813 metres
How often do you get those trigonometry questions when making a tracker or support frame and can't remember how to do it? The bot can probably help.
(Two sides and an included angle:)
<RossW> !sas 3 60 4
<RossBot> Side a= 3.6 Angle A=60.0
<RossBot> Side b= 3.0 Angle B=46.1
<RossBot> Side c= 4.0 Angle C=73.9
Or two sides and a non-included angle even:
<RossW> !ssa 3 4 45
<RossBot> Side a= 3.8 Angle A=64.5
<RossBot> Side b= 3.0 Angle B=45.0
<RossBot> Side c= 4.0 Angle C=70.5
Even converts your currencies:
<RossW> !$ 215 usd to yuan
<RossBot> 215.00 USD = 1356.40 CNY 215.00 CNY = 34.08 USD (From United States Dollars to China Yuan)
if you don't know the codes, use the country name usually gets it:
<RossW> !$ 3.15 canada to australia
<RossBot> 3.15 CAD = 3.07 AUD 3.15 AUD = 3.23 CAD (From Canada Dollars to Australia Dollars)
Does so many things, I can't remember them all.

RossBot is a show off! :P
Ross give me a cheat sheet once on the commands. I've saved it as a bookmark. Very handy.
