I have only come here seeking knowledge. Things they would not teach me of in college.


best website for cheap shit is www.taydaelectronics.com

standard NPN transistors for 13c, 555 timers for 10c, this place is a goldmine.
I had to buy 600 LEDs for my LED cube. I live in ireland, and to buy them from radionics here it would have cost me 140 euros. From tayda, it only cost 36! and that included shipping from HK!
great website/shop.

I love them but they do not do pre-made kits and you can find better buys on the same items sometimes by looking over reputable eBay sellers with 1000+ sales.  I've put together a couple of "kits" of inductors (my two LRC meters says their inductors are pretty loose on their numbers too) and caps with them and it's a bit of a pain.  With that said, they are great, ship out of Colorado, and get it to me in under 7 days usually.  I think they aggregate out there in Colorado so a lot of this is in the USA when they ship.

Just be thankful your not trying to enter into the world of 'golden ear' audiophiles. They select and buy their capacitors as if they are rare vintages of wine.




Ha. Ha.  What a bunch of tools.

I actually consider many audiophiles (aka golden ears) 'victims' that are feed upon by rather unscrupulous electronic suppliers that know better but can't help relaxing their morals for the temptation of high margins/easy profits that selling to such a population can be had. Many such audiophiles have a high emotional attachment to their love of music and the audio equipment they use to playback their music on.

As I said they give electronic components and circuits the same emotional attributes one might give to wine or art appreciation. When told about measurements (or even well run double blind hearing tests) not supporting such opinions on such 'magic component' they will just say that you are not measuring the right thing or that measurements can never substitute for one's refined hearing properties.

But in most cases such people can certainly afford their rather uneducated technical opinions with a higher then normal 'disposable income', so it's not surprising that there are people that will encourage such beliefs just for the easy profits. So as I said they are in many cases as much victims just succuming to other audiophile peer pressure and the technical gobbly gook that certain predatory electronic dealers are happy to feast upon. 



I'm going to be buying some capacitors and was wondering which ones were best. Ceramic or Electrolytic?

Depends on what you want to do with them.

Electrolytic caps are usually higher values (in the microfarad to thousands of microfarad range) and are used for low frequency filtering and power supplies. They, however, have a relatively high ESR and are useless at high frequencies, making them worthless for bypass capacitors.

Mylar and ceramic caps are much better as bypass caps, have a much lower ESR and lower leakage, but are only available in the picofarad to fractions of a microfarad range.

Which capacitor you use depends on what you need to do... there is no one "universal" type.

Where would you buy from? Spark fun does not have any.

Radio Shack. The prices aren't that great, but if you only need a few and you're in a hurry, that's the place to get them.
