Andriod App to help build coils

[ScottP]

So I got tired of manually calculating how long my wires needed to be cut and of what gauge and how many wraps I needed to get my coils to the proper resistance that I wanted. So I decided to make an Android app to do that for me. I also decided to put it up on Google Play as a free app.

The app is call Vaper's Toolbox.

Basically it calculates how long your wires should be, how many wraps to use, etc. to get the right resistance that you wanted.
I appreciate any feedback and I hope it helps you build the perfect coil every time.

NOTE NON-US/UK users: When I made this app I forgot that many countries use a comma to separate the decimal portion of a number. As a result the app may force close if you use a comma instead of a period. I will try to fix this in the next few days and re-release for my non US/UK friends. In the mean time try to make sure you use a period to separate the decimal portion of the numbers.

Real handy, appreciate the time and effort you put in it. I usually have my cell with me when I'm building so it'll be a good reference.

Awesome!!!!

Thanks for the app!

I have recently build my first coil, which worked perfectly to my surprise. I downloaded this app and I know it will be a big help to me. Thanks for this!!!

I only played with it for a minute, but it's a pretty handy app. Thank you for building it.

Very nice! Going to play with it when i drag my 30 or so gunked up evod heads out .. hold my phone over them and wait for it to build the coil. Can't believe you aren't charging for it! Woot!

I've meaning to do a similar app for iOs for some time, but been pretty busy updating most of my existing apps for iOS 7

Depending on how well this is received/used in Android I had already considered porting this over. I don't think it is overly difficult to do.

Very helpful.
Thank you!!

I don't have anything to use this on, so I have not looked at it, but I wanted to ask. As the number of wraps will very depending on the wick, (thicker wicks use more wire per wrap, thin wicks less) how does the app handle all the different combos?

Downloading now, thank you so much!

Great work ScottP!
Might I humbly suggest an addition? I.e another field to input the diameter of coil.
Would be good for those new to recoiling if the field has a drop down selection for, let's say
1) 1mm silica
2) 2 mm silica
3) 3 mm silica
Etc.
Last option would be to leave it empty for user to input in the diameter if the target coil is not in the selection.

Good job on the clean and simple interface!

Very nice! Installed... Nice clean uncluttered and functional interface!
Love It!!
THANKS!!!

When you fill in the diameter field, it uses that to calculate the circumference of the coil, then taking into account the lead length, it figures out how many wraps are possible with the remaining length of wire.

I will say this, if you are wrapping around a solid item with a known diameter such as a drill bit, screw, or nail, it will be much more accurate. If you are wrapping around something squishy like straight cotton yarn it may be less accurate since you could actually be winding the coil smaller that the specified diameter. For instance if you are using a piece 3mm cotton yarn, and wrap as tightly as possible you can compress that cotton down to as small as 1mm diameter.

If you start by filling out the fields on the 1st page do the fields on the other 2 update to match?
I.e., IF I put 30 gauge Kanthal -A on the 1st page is the diameter on the next page correct, or do I have to remember what diameter 30 gauge Kanthal-A actually is?

The Diameter is the target diameter of the coil not the wire. So if you are going to wrap around a 2mm drill bit to make the coil then use 2mm in that field.

Now if you change the wire type, gauge, or resistance on page 1, the length of the wire will be automatically recalculated and sent over to the first field of page 2. It then also recalculates the number of wraps needed. The diameter field will only change when you change it based on what you are going to wrap around.

Nice work!
