    Seattle Area?

    That's a good enough impression of the Seattle area, now for some details: Quote:Culture in general. Atlanta's is predominantly either rich white people trying hard to be sophisticated urbanites, or really, really poor people with a lot of crime - often within a stone's throw of each other. Suffice it to say I'm not a big fan of this arrangement. -Along the I-5 corridor between south Seattle and Tukwila is basically the poor area with plenty of crime (see White Center and Rainier Beach) while Mercer Island is the rich area. Outside of those two areas, it's pretty varied... Quote:Weather. Believe it or not, Seattle's climate appeals to me, over the nightmarish oven that Atlanta becomes during the summer. Just to make sure, here's a rundown of the general climate: -General: Cloudy... except for the summer -Winter: Wet, snows maybe a couple days of the year, except for the occasional snow storm every few years. Everett gets most of the snow if there is any because of the Olympic Mts. A warning though, an inch of snow on the ground causes almost every driver to panic and traffic grinds to a halt. -Summer: Clear and cool, 75-85 day, 55 night, with some occasional rain and maybe a small heatwave or two. Heat waves tend to last at most 3 days and it's a big deal on the news because only 10-20% of households have air conditioning. -Spring: Wet -Fall: Wet, windy Quote:what areas should I avoid? Crime reasons: Rainier View, Rainier Beach, White Center, south Seattle, Renton along Rainier Ave, Tacoma Quote:What kind of areas should I gravitate towards Redmond, Kirkland, and Bellevue are the big ones for the software person, maybe Seattle too, however it may be a bit pricey. The general area east of Lake Washington is fine but it's recommended to move somewhere where you can avoid taking I-405 to work... Quote:Are there any massive downsides to the area to be aware of? TRAFFIC: I-405 is horrible and I-5 in Seattle gets squeezed down to two lanes each way. As for information on real estate and the like, I dunno, internet I guess.

    Requirements to get an entry-level software dev position?

    The whole job fair thing: at the school's engineering job fair a while back, the common theme: "we don't have anything right now, but plan to have some openings in the spring, but we'll be happy to take your resume;" it was either that, or "just check our website for openings." It's really stupid to have the only engineering career fair 1 month after school starts in the fall instead of spring. I have no desire to give up on analog/RF and my intent with this is to get hired as a programmer at a company that also hires analog/RF engineers and hopefully try to transition internally from a programmer to an analog/RF engineer should an opening arise. Unfortunately, it was a big mistake on my part to not to do an internship over the summer (I had two summer classes) or to not slow down and postpone graduation a full year to take an internship (required classes only offered one quarter a year). Nearly all of the EE classes have lab components and projects. For example an RF circuits class would be: design a 3.3GHz amplifier with 300MHz bandwidth and 16dB gain and signals around 6.6GHz, 9.9GHz should be attenuated (since everything likes to repeat after high frequencies), now build and test. Some analog classes would be: 1) based on the professor's patent, design a filter whose corner frequency can be tuned by reconfiguring the filter to an oscillator via switches and tuning the oscillation frequency (since oscillation frequency and filter corner frequency should have some relation) or 2) design a fully differential opamp with 50MHz bandwidth, 60deg phase margin, 80dB gain, 100dB common-mode rejection, at 1.2V using 130nm technology with grades loosely based on which team had the lowest power consumption when no signal was present... I like the idea of sending unsolicited applications to companies I'm interested in and will try that. As for career fairs, I guess I'll try to be a little more enthusiastic about them but the previous career fair did not exactly give a morale boost to recent grads.
  3. I've graduated as an EE with a focus on the analog and RF side and right now I can find a ton of jobs in my area of study. The catch: everyone is looking for engineers with >10 years experience and rarely will an entry-level position appear. As I continue searching for suitable job openings, I've decided to try for an entry-level software development position (since they're plentiful around Seattle and I have an interest in it). I have do have a little programming experience (intro to java plus data structures and algorithms classes were required of all EE's at my university). Question: What is required of someone to get an entry-level software dev position? [EDIT] A better question would be: If you were interviewing someone for an entry-level software dev position, what do you expect out of that person with respect to the technical side of things?

    Im going soft in my old age

    Quote:Original post by bzroom I just moved from Sammamish to downtown Seattle and i was so happy to be getting out of spider country. But then within a few hours of being at my house i saw the biggest spider i've ever seen in my life. It was about 3 inches across its legs. These are the kinds of spiders that terrify me. I have this illusion that if i go to step on it, it will like slip out from under my foot, landing me on my back and then attacking me. Or if i try to smash it on the wall it will like evade the weapon and leap onto my hand. Anyways, i smashed the crap out of it. Layed it on the counter until i could identify it. It was the non-aggressive type house spider. Scary looking though. I haven't seen any spiders since then. I'm definitely on look out. First time i see one around my bed the whole room is getting fogged. I used to think, oh i'll let it live, they eat other bugs.. Sure they do, but they also multiply by the thousands every year. So if you kill one, you prevent millions. I dont want wolf spiders raining from my ceiling, so they all die instantly on sight. I paint houses over the summer and two years ago I was painting a house on Queen Anne, just the windows, soffit, and front porch since it's a brick house. Both the front porch and soffit were gray (original: white) due to the sheer amount of spider webs. You paint a section white , come back the next day and see that its gray again... I hate spiders and especially hate their webs so it's kill-on-sight for me. Best way to kill em if you can't stomp em I've found is to take some masking tape and wrap it around the end of a pole with sticky side out then shove it towards the spider and its web. The tape is sticky enough to catch a couple legs, then bring it down to the ground and stomp on the sucker. If you got a fast spider, try spray glue, after a few seconds the spider should be slowing down as the glue becomes real sticky, eventually stopping it.

    Educational CAD software

    Autodesk does have a student thing where you sign up using your university/college email account and you get to download AutoCAD and other software that work uninhibited (for educational purposes I'm sure)for 1 full year. After the year is up, they usually have a new version and you can download that. http://students2.autodesk.com/

    noob oscilloscope question

    Quote:Original post by bzroom I use scopes as cracked out volt meters. A 4 channel scope is invaluable for debugging a serial comunication bus. So i'd recommend at least a 4 channel, and preferably one that has a webserver so you can log in from your computer and download/view information. Good for posting on forums with questions about what you see. Or asking the manufacturer. Sounds like a waste of o-scope resources if you ask me... If your debugging only concerns digital data ie you only care about 1s and 0s, then you should instead use a logic analyzer, you can get like 32+ channels and it should have a PC interface. Shoot, you can probably find a few diy logic analyzer projects online that can sample at a few megahertz. O-scopes are for the analog waveforms. In the digital world, that means that o-scopes look at the rise and fall times, whether there is ringing, etc. A 4-channel o-scope will obviously cost more than a 2-channel and most times you can get away with only 2 channels. By the way, I REALLY DONT recommend getting a one channel scope. Quote:Original post by oldoldoldman Since I'm in my 60s and don't have any training you have a good point. I have been fixing monitors by comparing them with each other, that is one that is working with one that is exactly the same but is not working and slowly running down the bad parts that way. I found out that I SEE a lot more with a good multi meter (FLUKE) than with a cheap one. I keep finding new parts that I want to see into what they do and think I can learn to use a scope on my own time with time. What do you think? If you really want to learn to use a scope, buy a few opamps (741, NE5532, etc) and build a few analog circuits that work in the audio range. This should get you acquainted with the oscilloscope and what various knobs and buttons do. The last thing you want to do is fry a channel on your scope or the device under test because you connected something wrong (eg high voltage signal for backlight) on accident; I killed an RC car electronic speed controller that way.

    noob oscilloscope question

    Don't know the specifics of vga/hdmi but I'd guess that a 60-100MHz scope might work for most repairs. Probably want to up the scope bandwidth as you get to bigger resolutions and standards such as hdmi. Keep in mind that for signals over 100MHz, an active probe is pretty much required and those are expensive. Also, if you get an (X)MHz scope, does not mean that you'll be able to see an (X)MHz square wave, you have to keep in mind all the extra harmonics of signals and that will push the required o-scope bandwidth up.

    What's a good book to get started with electronics?

    Fundamentals of Electric Circuits I've heard is a good book. I had this one Electric Circuits, it sucks majorly in the beginning (aka the fundamentals) but becomes more useful in the later chapters in my opinion. From there, for diodes and transistors, Microelectronic Circuit Design seems pretty good, plenty of examples and derivations, it also has stuff on amplifier design. This one, Microelectronic Circuits, is also recommended by others. For some nonlinear stuff, the later chapters of both Design with Operational Amplifiers and Analog Integrated Circuits and Design of Analog CMOS Integrated Circuits have some info how some nonlinear circuits work. The opamp book has some pretty good stuff in general and do recommend, while CMOS book is only maybe good for some of the nonlinear stuff unless you actual went into industry doing this kind of stuff. The Art of Electronics book is dense for the beginner plus I don't recommend getting it because there should be an updated version out in a year or two. By then you should have a nice grasp of the fundamentals for the AoE book to be useful. Those books should help you with any analog circuit design, as for digital, I don't know, I'm finishing up my EE degree in analog/RF while digital I'll learn over the summer (the tools for digital are much cheaper than analog/RF).

    Space Exploration!

    Quote:Original post by Talroth Depending on the nature of the probe, having a few thousand isn't that unreasonable. A few thousand advanced rover probes wouldn't be likely, but very basic stationary probes? The more the merrier of those. Just think of the useful data you could get in 2 years with 2000 soda can sized sensor probes scattered all around the Red Planet. Since this seems like an interesting project idea, what kind of sensors do you think these probes would have? Is the probe stationary? Are the probes far apart from each? Is it 2000x of the same probe, or are there different types?

    Did I just get electrocuted?

    Quote:Original post by benryves Quote:Original post by Marmin It's the current that does it, not the voltage.Current being a function of voltage and resistance, of course. [wink] And by that, contrary to what Ravuya says, DC can kill. Lightning is mostly DC and it can kill no problem. Difference with lightning vs a car battery is that lightning produces a voltage potential in the 100s of millions to billions of volts (breakdown voltage of air is 6 million volts per meter) and 600+ million volts across a human (10s of millions of ohms for dry) can still produce enough current to kill. By the way, most places/books/whatever, assume that anything above 48V, DC or AC, is high voltage. Oh, and the 120V for US is average (RMS), peak is +/-170V.

    PIC programming anyone?

    Quote:Original post by Krokhin Quote:Original post by aleisterbukowski I have just recently really gotten into PIC programming lately, and I'm wondering if there are anyone who devotes their hobby time to making PIC programs for or as games. Rather it be a small game on an LCD, an LED game through input from a computer application, or robotics modeled to play a certain game? For robotic models more suitable Analog Devices microconvertors ADuC841++ or other analog controllers(Fudjitsu etc),based on 51-instructions set.They have enough memory size for C language stack,almost AVR(RISK) speed and free C compilers.In addition you will have ADC/DAC devices on-board,ability to write in program code flash in your program and pretty fast code upload in processor via simple USB-UART bridge:) PICs from 16F and up all have ADCs on them, not sure about the smaller ones. The dsPICs also have a DAC on it along with a DSP engine. For robotic purposes, there are usually motor controller variants that have more PWM outputs than the general purpose versions. The 18F series and up are designed to be used with C (but of course you can still use PIC assembly though not really recommended). Some of the 18F chips like the 2550/2553/4550/4553 also have a full-speed USB peripheral that you can set up and use. As for the OP, I've got a bunch of free IC samples from Microchip and all I need now some free time to learn and do some projects ie a robotic arm. In retrospect it would of been better if I had bought a kit instead of getting the ICs themselves even though I have plenty of components lying around. I'm really digging the PICKIT2 programmer with it's UART tool and logic analyzer though I wish the logic analyzer could handle higher frequencies.

    Christmas list

    Quote:Original post by DarkInsanePyro I am not selfish... I have tried to ask for nothing but it tends to make things even worse in the long run. Even though that is true, everything I want is out of my families price range so they are SOL anyways. :x What I asked for was BestBuy gift cards, as I want some new equipment (HDD, etc). What is my real wish-list than? [Quite Expensive] 1) Dual-Channel 1GS/Sec Digital Oscilloscope 2) Dual-Output Power Supply (specifics not included but exist) 3) Function Generator (again, specifics can occure) 4) Tablet Laptop [Found a good HP one for $900] 5) External MyPassport Harddrive (500GB for Powersuppy-Less Version) [~$200] [Averagely Expensive] 6) 1.5TB Internal Harddrive [Easily $100 at most] Now, this is just on the top of my mind. There was a few more but at the moment I cannot remember. Again, I am not expecting to get any of this, and I wouldn't even ask for them in a serious manor. These aren't really for thought, as it is more equipment than personal material. :P I know it's out of the price range but to nitpick, you would want to also specify the bandwidth of the oscilloscope. Just because the o-scope does 1Gs/sec doesn't mean its analog input stage would be able handle very high frequencies without degrading the signal (ie phase, amplitude...). For example, there are oscilloscopes (equivalent time sampling) out there designed to measure repeating signals to very high frequencies (>1Ghz) while using ADCs that sample only around 20-100Ms/s, so while the ADC is slow, the analog front end needs to handle the high frequencies. As for my list: [Once I graduate and finally get enough money] -100MHz (or greater) Dual channel oscilloscope (digital or analog) -Dual Polarity Variable power supply (100W is good enough) -Function Generator (25MHz square wave seems good enough though expensive) [This Christmas] -This Aoyue 968 SMD Rework Station ($100 from family, $50 from me)
