Identifying Resistor Values using iPhone’s Camera

at 10:21 pm. Filed under Electronic Hacks

 

Are you  color blind? Then it would be hard for you to recognize the resistor value while working on projects. Rich Olsan from nothinglabs developed a cool iPhone application for you guys which helps identifying the resistor values through its camera. All you need to do is install application on your iPhone and follow these steps.

“Using resistor ID is easy:

1. Take a photo of a 4-band resistor using the app

2. Drag the numbered bars over the corresponding resistor bands

3. Resistor Photo ID provides you with the resistance and tolerance of the resistor!

If for any reason Resistor Photo ID doesn’t detect the correct color for a band – you can easily override it”.

    I’m pretty sure it’s faster for a color blind person to just use a multimeter or something…
    This app might only be useful if the resistor is already mounted on a fully populated board (it’s not possible to measure it with a multimeter then because it might be in parallel with another resistor or something)

    [...] Photo ID app for iPhone via Hackedgadgets. Rich writes – I shipped a new iPhone app a few weeks ago – “Resistor Photo ID”. [...]

    @Brad.. An Ohm Meter could not give a resistor’s tolerance value, temperature rating or even its resistance value if were defective. If the app is truly intended for the color-blind you would think its interface would be optimized for contrast instead of using color. Perhaps it has a setting to toggle between ‘color-blind’ and ‘stupid/lazy’, err.. ‘teaching’ modes.

    It’s not clear what value the ‘iPhone App’ form factor gives over a portable application that could take input from any imaging device or graphic image file (which already exist); nor is it clear why an app for a device intended to run apps would be featured by a “Hacked Gadgets” feed.

    Wouldn’t a universal OSD color to color-name converter be more helpful, in general, to a color-blind person using a mobile device? With that they could read the color bands of a resistor and also know the color of anything they encountered in the world. Why limit such a tool to such a specific simplistic singular purpose? It could provide single pixel conversions or range conversions along a single pixel “cross-hair” (or other target shapes) to quickly identify virtually anything they were previously unable to (boxer/sports-player by color of trunks and shirt, flags, traffic signals, food, etc..). Quite often, less is more.

    Now if it could do 1% and 2% resistors, that would be useful.

    what is the old school saying to remember the colour pattern?
