Resistor App

[Guest benboy00]

Hi guys,

I made this app recently, as kind of part of a school project, and i was wondering if anyone could test it on their phones. I already tried it on my desire hd, and it worked ok. I'm mainly interested in how the graphics look, but if you see any other problems with it, it would be great if you could tell me. I hope to publish it to the market when i know it totally works, thanks :lol:

Basically, the way it works is you put the resistance you want into the box, along with the tolerance, and press convert. It then turns this into the appropriate colours and displays it on a picture of a resistor. You can also select colours for the resistor bands, and then press convert, and it will tell you the value of the resistor. I hope later to add other stuff, like parallel/series resistance calculators and other electronics stuff, but i want to see if this works first.

(btw, there is kind of a small easter egg. its not very good/big, but i thought it might be fun anyway. make sure your volume is on)

(also, this was made in AppInventor, so sorry i cant do anything about the size :) )

Type 42 into the resistor value box...

Plz download, it will only take like 5 min to test.

Thanks,

Works on my ZTE Blade and the easter egg makes a sound too.

As for the layout only thing I can think of atm is might be an idea to label the colours either on the resistor pic or by the band selectors somehow.

Thanks very much for the quick response :lol:. Do you think it would work if i put the name of the colour in the colour band itself, in a slightly different colour (so you can see it)?

Hello,

I just tryed out your app, it works :)

The only thing I saw is that there are two colors missing for the third band (gold & silver).

The startup thumb should be a little bit higher in resolution :lol:

Thanks for the help :) However, the only the fourth band of a resistor is supposed to have silver or gold.

Will change the resolution accordingly :)

Sorry but that's not true, how can you display 1 Ohm or 0.1 Ohm with your program if you didn't have those two extra colors ?

Your SW can only display 10 Ohm but not under ;)

I'm using such resistors for shunt's so I'm very sure of it :lol: look at the 27K series.

Sorry for doubting you :)

Although, i've never actually seen <10 ohm resistors.

But thanks very much for testing my app :)
