PV Web Apps - any other ideas, suggestions?

[TomCatt]

I've been collecting and writing some web apps (calculators at the moment) that may help some (and amuse others, I'm sure ) in rebuilding rebuildables.

I have a Ohm's Law calculator; a 'Coil Length & Ohms' calculator; and a calculator to determine how wide a piece of SS mesh you can roll up and still have it fit in your genny-style atty wick hole. I've extended the Ohms per Inch table for various resistance wires and have my own version of the "Wattage Table".

Does anyone have any ideas or suggestions for additions to the PV Web Apps page?

What a great tool! Thanks for pulling this together and hosting the web site.

Here are three ideas:

1) How about linking the Ohms Law Calculator with the Coil Length Calculator to get a standardized power measurement: Watts per inch/mm of coil wire?

2) A calculation that provides distribution of power over the coiled wick length: Watts per sq inch lateral surface area of the coiled wick length?

3) A calculation that incorporates the "amount of mesh you need to roll a certain diameter calculator" to provide a power to coiled wick volume ratio: Watts per cubic coiled wick length.

Probably much easy to describe than implement. But it may help people to understand why certain people get great results with their mods and why people can not replicate them. Myself included...very often.

Hmmmm, very very interesting. Let me cogitate on that some ....

Here are a few other interesting liinks. Reference chart and a sliding calculator for determining wire temperature, etc.

Thanks, g. I haven't forgotten your suggestions, have been busy elsewhere recently. I hope to work on them some time soon.

All good.... just wanted to put a placeholder/suggestion in here for reference. I have number of these book marked on my PC.

Tomcatt....

Not to keep you busy, just another nice calculator.

Some people ask the question, "How long will my battery last?"

This will allow them to find out based upon what type of battery they are using.

peukert is around 1.2 to 1.3 for our application based upon a bit of research.

Sorry I have a bit of OCD.....

Hey g, added a voltage selection in the 'Calculate the Length of a Coil' calculator to now obtain a wattage value.

Re-doing the Ohm's Law Calculator (writing it from scratch, instead of the copy that I had done) to be able to set up the Battery Life calculator. Should have it done soon.

Got the batt life (and # of 'draws' per batt life) calculations working; but the page formatting is all wonky. Will hopefully get it straightened out tomorrow and uploaded.

I got everything looking ... OK . And it all seems to be playing nicely together.

Updates:

Ohm's Law Calculator/Battery Life Calculator -
You can enter a Voltage and Resistance to calculate the Current (amps) and Wattage. A default Battery Capacity and # of seconds per draw are entered just to keep things straight; this is for the Battery Life/# of puffs calculations. You can ignore the Battery Life/# of puffs if you're only interested in the Ohm's Law calculation. BUT, you will need to enter a battery voltage and atomizer resistance in order to generate a Battery Life/# of puffs.


Calculate the Length of an Atomizer Coil (Ohms/Watts options) -
The Ohms (resistance) of the coil had been added a while ago; now there is a wattage calculation added if you select the voltage from the associated drop-down list.

Wow. Fantastic work.

Thanks for your efforts here.

Thanks for finding these equations g
