    Do you remember when work was fun?

    The problem with ISO9000 is that it introduces changes in the way companies are managed. The paperwork becomes a support for all the top management decisions. But what really happens nowadays is that managers don't like being told what to do, so instead of following the ISO "advices", they just...

    I'm hoping that this is not typical corporate behavior...I guess

    I once worked in a firm like the one you say. My boss was a lousy manager and the specifications for the project I was in changed daily. And instead of refusing this situation with the client or billing him for it, he expected me to put in overtime to compensate and to meet deadlines that...

    Variable power supply

    It is! If you want to control the heat, you must do some circuit with a temperature sensor. ;)

    Variable power supply

    Thanx, I've came up with the LM338 from Linear Technologies, that allows me to connect these devices in parallel in order to achieve higher current output at variable voltage. And without any additional components. ;)

    Variable power supply

    Hello, I'm trying to build a variable DC power supply, I'm using TL494 for PWM and a NPN transistor as the switch. I'm using a Buck topology, and my problem is that my voltage is fine without any load applied to it, but when I connect a simple led with a resistor the voltage drops a lot. I'm...

    what language should I use?

    I would go for VB. It's quite simple to build an application as the one you described. I've made one with little or no difficulties and had very little knowledge of VB at the time. Depending on your microcontroller, you can use baud rates that will give enough speed for the application (I used...

    How to resign amicably from a job

    I guess the best way is to be honest and show you current employer that this is an offer that you cannot pass on. Along with it should say that you care for the company and you're willing to pass any info about your work to the person that will be filling your place. However, you shouldn't let...

    Thermistors

    Try searching some Application notes in www.epcos.com. In any datasheet you can find a lot of info about the specific Thermistor which is similar to everyone. ;) Don't forget to keep an eye on the response time of the thermistor... Some take a bit of time to settle in the desired measure...

    Exhaust and particle capturing

    In my company we're building a new maintenance shop and we need some sort of portable exhaust for the fumes and particle capturing. Can anyone give me some brand names that may have this sort of product? :\ Thanx in advance

    I do two jobs and get paid for one

    Hello, I think that if you're getting paid and you feel conmfortable (besides the fact of the two jobs) you should stick to that. People are more close and friendly in smaller companies than in big companies. And by doing a variety of tasks you're only gaining value in the work market. ;) It's...

    Getting back into engineering

    Hello, I believe that when something is understood, it never leaves us. The brain just tucks it away under a big matress inside our heads... What we have to do is just lift the matress and see what's there. It's easier said tha done, though... LOL If you're planning on doing construction...

    Mobile phone flasher

    My laptop doesn't flinch when my cell phone rings... I know this for sure. However my pc monitor in the work place will. :\ It's not the flashiest solution, but... It's a solution :P Thanx

    How to get more satisfied on what you do as Job?

    I'm currently going through some problems like the ones KOUA11 is having. I'm in the maintenance area and my boss is in the company since the year I was born :| And everyone trusts him with their problems and some times just pretend that I don't exist. This is in part because of the fact that...

    Mobile phone flasher

    Hello, It's like this, My new office will be a bit noisy, so I'm planning on working with some sort of headphones on my hears. Since the headphones will most likely damp the noise from the cell phones ringing, I thougt on doing a gadget that will flash a light every time the cell phone rings...

    Buggy Software

    You definitly made a point there. Cars are as complex or more as any software, because they are a mix of software and hardware. But the caring, knowledge, testing, and more testing that cars are submited to makes a difference. Software on the other hand is made and tested only once or twice...

    Automatic delete files

    If you needed a solution for your problem, you've just got it from above. If you want to learn how to code it, Google will have the answers for you. :P

    Mobile phone flasher

    Does anyone knows how to build a mobile phone flasher? I guess it has some sort of coil which transforms the waves in power, but I haven't found out how. Thanx in advance, Carlos Cardoso

    Automatic delete files

    Try using the FileSystemObject. It allows you to perform several tasks on your file system. Put a timer interrupting from minute to minute and checking if it has reached the pretended hour. Then you just need to delete the file via FileSystemObject. Don't forget you must keep the program on...

    Buggy Software

    Most of the times these bugs appear because of poor management... Either high management gave the customer impossible deadlines that the software designers couldn't keep and something missed checking. Or maybe the software designer didn't have all the information to begin with... Another...

    How high of a degree should I get?

    My advice is for you to get some real work experience. See what you truly would like to do for a livin' within the engineering business. And then decide on what should be the best step to take. Engineering is a field where we must always be up to date with new technologies, and the evolution is...
