[QUOTE=DrDevil;43760702]I would like to see proof for your claims.[/QUOTE]
Easy,
for a start, usually the best equipment is made by companys or groups that designs specific things.
A peice of equipment like that is almost cirtaintly made by a single group of people.
If i buy seperate equipment, say, tektronix make the best oscilliscopes, agilent make damn awesome powersupplys and weller make the best soldering irons.
or if you go with an agilent oscilliscope, agilent powersupply and wellet soldering iron
likely the oscilliscope and powersupply are designed by seperate groups, as a result they will likely be better then say, a powersupply-oscilliscope combo :P
Another example:
If you have a group, 2 experts at soldering irons, 3 experts at hot air guns, 2 expert at powersupplies,
likely the product will be worse off compared to, if you have a entire team on each product.
Also, at our college we have a frequency counter - powersupply - frequency generator - volt meter combo and if one module breaks, the rest of them do so too... there is my argument...
Also, you shouldn't need proof, im an astronaut riding a horse, what more proof do you need.

What you're saying is utterly ridiculous and isn't in any way or shape proof. What prevents the company from just getting together a bigger team?
Do you need an expert to create a basic powersupply or soldering iron? If you want high end products you have to buy high end products. We're clearly talking about hobby/mild professional use here. Really the only substantial argument you brought up is that if one part breaks, you can't just replace it. But that still stands against my space saving and free power sockets. In the end it comes down to personal preference, but the all-in-one products aren't generally worse than seperate products.

Wait why has he got to prove anything? Its you making the claims... Cmon guys this is an engineering thread proof is an objective quantifiable thing not your opinion
[QUOTE=metallics;43761557]Wait why has he got to prove anything? Its you making the claims... Cmon guys this is an engineering thread proof is an objective quantifiable thing not your opinion[/QUOTE]
And he is equally making claims it's not, i have given my own proof (the products breaking down at college)
I don't use kiddy supply and equipment, i use equipment from proper brands (Agilent, Weinstein, HP, Hitachi) not cheap Chinese crap like most of those combo products.
While those things are 'fairly good value for price' they often will not last as long compared to professional second hand gear from my experiences.
2 or 3 in one products usually use the same power supply internally, this means that if one part breaks, there is more of a chance for the rest of the parts to break, compared with 2 pieces of test gear on your bench.
I also like individual equipment because it looks more professional :)
Mabye it is just my opinion, but still, try proove me wrong, i have yet to see a single 3 in 1 or 2 in 1 product in any workplace ive been too.

I think we're talking about two different things here. I am talking about combo-gear in general, while you seem to be talking about cheap chinese crap?
Of course the chinese crap won't ever be as good as proper gear. Proper gear always has the better value for money (even though the price is usually way higher), but chinese crap gear has better entry point prices. You have to see what you can afford and if it is worth getting it for this price.

(Also I really don't wante to continue this discussion, seeing as it is really pointless)
So I found something today called Processing 2, and this picture should say quite a lot about it :v:

I can not really explain a lot about it because I didn't use it myself yet, but I found it [URL="https://www.youtube.com/watch?v=2_c0yE9QHNI"]trough this video[/URL] and it looks very interesting. I've been wanting to make programs which can read serial data and use it for stuff for a while now, and this looks exactly like what I need.
Anyone have some advice for getting started with arduino stuff? Like what to buy (Shields, extra hardware, etc.)? I'm studying electrical engineering right now, but I don't have too much experience with electronics (only basic circuitry stuff). I'm familiar with simple coding though.

i would get the Arduino Mega, Ethernet Sheild, Protosheild for the Mega, mabye a few others
when you are more comfortable with it, get somthing like a STM 32 F4 Discovery, thats what im playing with atm
To be fair the Uno has been plenty for me for a few years. If you tend to run out of pins, you can still use clever tricks to "gain" pins
[editline]6th February 2014[/editline]
but if price is no issue, you might as well get the mega to be 100% you will have enough connection points.

Just keep in mind: You're going to become an engineer. Arduino is an artist tool, and in your case is only really useful for dipping your toes into the world of microcontrollers.

With that being said, AVR is arguably the best microcontroller all around. I recommend the Atmega88 as its the "Smorgasbord" platter of utilities (UART, I2C, ADC, PWM, etc).
Look into using the [URL="http://winavr.sourceforge.net/"]WinAVR library[/URL] they have a very [URL="http://nongnu.org/avr-libc/user-manual/"]comprehensive documentation[/URL] along with it being supported universally by the AVR community (AVR Freaks is a great place).
Alternatively you can use the arduino as an AVR development platform (arduino runs on AVR).
Was replacing a SIM card holder on a phone, managed to break the holder and rip off a pad. fml.
the Arduino and that processing stuff might be artist tools, but they're a good place to start at as they're friendly to use. After that you can specialize in stuff.
Arduino is also easy to use when making very early prototypes, as you can change stuff around quickly.

How on earth do you break so much stuff, are you de-soldering with a blowtorch or something ?
I love the arduino, it seems to get so much stick simply because the barrier to entry is so low.
There's one under the dashboard in my car that has been converting the propriety Citroen steering wheel buttons to the sony head unit standard... faultless for the past year, even if it did look like a pile of crap. I built the prototype and it worked so well I left it.

Before this I was using PIC16s and programming in C. I personally wouldn't go back to that.
I do think there's lots of people out there doing things with them that could be done with fairly simple discrete circuitry, though.

been playing around with this chip
calculations are easy enough for a 12 year old to do...
going to give the circuit a try tommorow, managed to prototype one of the demos in a single lesson period, did the math out for my own to make tommorow evening :)
here:
Vinmin = 25V
Vout = 12v
Ct = 0.33nF
Rsc = 0.15R
Lmin = 50uH
Cout = 80uF
R2 = 13k
R1 =1.5k
took all of 15 minutes to do :)
I want to play with an Arduino Due-- anyone have any experience with it, especially mobile uses of it?

I believe most of them are some shady old russian stocks that were rotting away in some siberian warehouse until someone found out that you can sell them for lodsemone on ebay.

Processing has been around for quite some time, longer than arduino IDE (As it is a decendant of processing IDE).
I love processing as a concept, it is really easy to "sketch" up some code for visualization of data, or just play around in... Plus it can run stuff in HTML5 and on android too!
I do miss proper IDE functionality though (same goes for arduino IDE).
Processing can be used as a library in eclipse, that helps alot if you are already familiar with java (You have to do a little boilerplating to get going, and you can't use any of the pre-compiler trickery of the processing IDE).
Alex's guide to cheapskate repairing mobile phones:
Alright first find the problem and look at the original replacement part cost. Now what you have to do is look up for something close to that part from off the shelf parts ( fuck paying $10 for an original sim card holder). In my case i wasn't able to find ( didn't even search that much ) an exact replacement, however the one i got was close enough.
For repairing something and sensitive to ESD as a phone you should wear an ESD strap.

Make one yourself from some tinfoil, crocodile clips and 1Mohm resistor ( fuck that expensive $1 shit on ebay)
Alright, now get the old part off that board with any tools you seem applicable ( i used a dremel with a cutting disk )
Now since I'm a cheapskate my part didn't really fit the old solder pads, so i had to extend some of the part's pins to the solder pads using resistor leads. Also used some magnet wire to connect directly to power decoupling capacitors since i ripped off one of the solder pads.

After you are done, don't clean the flux off as isopropyl is expensive and not in a cheapskates inventory.
Add tape to make this abomination repair job sturdier.
Tomorrow we'll start programming an Arduino using AVRstudio(4) at my study, combined with the WinAVR compiler. Does one of you have any experience with it, and perhaps some things I should remember?
So my coworker took apart a laser printer and gave me the laser module itself, complete with awesome lenses and optics... and a little motor looking device that upon simple research is actually an electromagnetic clutch.

It took me a minute to recognize how it was used but now that I know what it is its pretty obvious. Also its adorable, but thats because the closest one to it I'm familiar with is

Now, my question is, what could I use this thing for?
Oh electronics, you are such a heartless bitch at times.
