Found the Mother Load

That's right, I found my department's stash of old parts.  Tons and Tons of carbon comp resistors, caps and Trannies.  Cha-Ching.

Are OC41's good for anything?  I looked for the obvious OC44s and AC127/8/9s and haven't found any yet.

The OC41 Datasheet gives them an hFe of 35... not too great for fuzz really, other uses? Dunno.

Taylor

So do you just have free access to all this stuff, or...?

aziltz

well yes and no.

its fair-game for my research projects, but I don't really think people will miss a few components that won't ever be used anyway.

there are a ton of older opamps and tubes. I'm hoping to grab any usuable Ge devices.

I will hopefully be having some similar luck soon. The Assistant Lab Director told me he'd round up all the old tubes the department had left and that I could have them since he didn't want them. I am thinking of asking him if they have anything else they want to get rid of because there is just rooms and rooms full of old parts that will never see use again because they are outdated and Bradley ECE Department doesn't have any classes on analog charm or engineering in the 1950s. :P

Pretty neat, guys. I guess you deserve some cool parts after dropping 30k a year.  :icon_smile: If you guys run across any matched transistor arrays, I hope you'll let me know...

I've scored a lot of cool old stuff from my school by helping out and keeping an eye on the electronics recycling area. That's where I got the metal can ua108 for my Rat. I also got a bunch of those old GE transistors that look like top hats. I could probably make $50 on ebay selling some of the trannies, but I like the idea of using them better.

who's dropping 30k???  i think anyone who pays for graduate school is getting ripped offl, no offense.

for the record, this is physics and I'm lucky enough to get paid to study.

i'm in grad school, they're paying me to be there.

I'm still an undergrad... One more year to go.

Not really. You had better send them my way so that I can dispose of them properly... :P

Hmmm. Maybe make some buffers out of them?

::) I'm very happy for you, but chill out. I took a quick look at the website of the only school mentioned here (Bradley), tuition's 30k. How am I to know you're a grad student?

Electrical/Computer Engineering

Basically Electrical Engineering with the Computer option track of digital courses so I'm technically an ECE major instead of an EE...

it really wasn't meant as a look-at-me comment.  I've edited it several times now to try and get the right message.  No harm done I hope.  I admit I got my wires crossed about the 30k comment...



ECE sounds pretty cool.  I really wish I had more electronics background.  I end up using more than I really get to learn and its frustrating.  They don't really teach you apparatus design and construction, you kind of learn on the job, which can also be fun and rewarding.

OK, this has got me interested - who can translate this 'graduate' / undergraduate / whatever thing in to English?  And by that I mean 'as in the Queen's'!!

I quite often hear these terms, and assume they apply to post-High School learning - but we use completely different terms in this part of the world:  High School is High School until 17-18 (or 16  ::)) years of age, then you go to University, typically to "do a bachelor's" = ie the obligatory BSc etc... then, if you want to do any more, it's typically in to a Master's degree, then a Doctorate.  Or at least something along those lines...

So where do the North American terms fit in this scheme of things?

(just interested!!)


aziltz

Undergraduate refers to the first 4 years of "College" or "University" in the EU.  Working towards your first "Bachelor's Degree"  I went from High School straight to College for 4 years and I now have a Bachelor of Science in Physics. (BS)


I'm now in Graduate School, working on a Ph. D. in Physics.  This will take about 6 years and I just finished my first.  I'll also get a Masters of Science Degree (MS) after next January as a stepping stone.  Its also called Grad School because all the students have already graduated with a bachelors degree in something.

They're are also Bachelors of Arts and Masters of Arts degrees, which for all intensive purpose signify nothing.  They usually correspond to taking a few more classes outside of the chosen field than the "Science" Degrees, but it depends on the school.

I think it would be nice
if members would post there location
along with there real name.

You graduate when you get your Bachelor's Degree. If you continue to study, you therefore are doing graduate studies (towards a Master or a Doctorate). Typically these graduate students have brains, but no money. After they graduate, they get to work for people who have no brains, but do have the money... Maybe they would have been better off, dropping 30K for not having to do graduate study....

I know, but the pedal i built does not boost...it just increases volume!

i don't see 30k for a BS will get you farther than any graduate degree.  you just have so many options out of grad school its silly.
