content: Hey, long time without visiting the forum, just wanted to show my iPhone appand hoping you guys can give me some feedback, the app is going to becomea toolkit for every electric engineering student, currently it can solve linearequation systems, determinants and it can approximate a given resistance withcommercial resistors.Best part of this, it'sFREEhttp://itunes.apple.com/us/app/matsol/id389393518?mt=8Some screenshots:Tap the value of a resistor to get the color code:Looking forward to hear your comments.

content: Looks great!How hard is it to start using Objective-C? I read that you require an Intel Mac to compile the iOS App... is it true?Did you pay 99USD to be able to publish your electronics App?Sorry for the questions hehe... I'm just curious.

content: Just installed this on my iPod Touch, looks very nice.Thought I would suggest a few things you could add:Ohm's Law calculatorResistor Color Code calculator(enter color code, get value - enter value, get color code)Binary, Decimal and Hexadecimal converteretc...

content: Quote from: migsantiago on September 15, 2010, 03:20:37 pmIf you are comming from C++ it is very easy, or even C. Yes you need an Intel Mac to compile apps running in iOS, though to be serious that's just a trick Apple is doing to make everyone move to Intel, the same thing they are doing with Snow Leopard, they are setting it as a requirement for most of it's software. You have to pay if you want to publish something on the app store, even it it is a free app.We are planning to add more things, please keep the suggestions comming & thanks for downloading/using the application.

content: Quote from: Vexer on September 15, 2010, 10:26:14 pmWe are adding the Color Code calculator in the next release and in a future release we will be adding the Base converter! Thanks for the suggestion!If anyone else has any other suggestion please post it here or in the app store page, thanks a lot!!

content: I'd like a Windows version, even if it's command line (no fancy graphics) I'd be happy.Even better, make it open source so it can easily be ported to many platforms.

content: Quote from: Hero999 on September 28, 2010, 03:19:27 pmThe UI would need to be different, and you probably wouldn't use objective C either, so what part would you reuse? It's not like the math is obscure. A javascript version on the web might be less work, if there isn't one yet.

content: Quote from: ArtemisGoldfish on September 28, 2010, 06:34:36 amWindows Mobile is probably the worst Windows ever made. How about open source your app so someone can port it to mobile Linux (Android and others) and maybe even Rockbox?

content: Quote from: alm on September 28, 2010, 03:53:05 pmDamn, I hate to admit it but a Javascript version of this would be great, though I don't have the time to rewrite it and I kinda hate jsBTW, there have been a few updates to the software, it has a base converter now, go, check it out:Feedback is greatly appreciated!

content: Quote from: yoshiki on December 23, 2010, 07:02:21 amI like javascript , you should make a js version, so that your software has a longer lifespan. I have seen good softwares that couldn't handle newer os and slowly fade away. It's a shame really, endless hours writing and debugging and the software goneBy the way, do you use your software frequently and have other student engineers find it useful? I too know how good it feels to have other people using softwares we write.

content: Quote from: MrPlacid on December 23, 2010, 09:01:44 amI have to admit that you are right about the lifespan of a software product, specially a free product but oh well.Yes, I have seen lots and lots of students using this @ my University I haven't seen whats the use they give it in other Unis but I guess its similar, it's a rewarding feeling knowing someone uses software you have written.

content: i have made a VB version of a resistor colour code calculatorhttp://www.resistorhelper.orgit will convert colours to values and vice versa, 4 and 5 band resistors plus gold and silver multiplier bands as wellits only in windows though
