Buying from Ebay

[PolyPhukin]

Not sure if this belongs in this section of the forum, but anyway..


Does any one ever buy IC's, germanium diodes and what not from ebay sellers?

Is there anything to lookout for in terms of buying duff components?


I really want to build this

Taken from www.musicfromouterspace.com

Its an LFO with two sine, triangle and square wave oscillators.

If you're not fussed for the sinewave you can leave out R10 and everything south.

Pretty much any opamp will do, although I recommend sticking with the TL082/TL084 chips because they're cheap and fairly reliable (except, it seems, in Ensoniq Mirages).

oops i forgot to put in the full link of that page; http://www.musicfromouterspace.com/analogsynth/NewAugustSIN_TRI_SQR_LFO.html

I just thought it might be useful to have a small box with various LFOs in so i could hook it up to my bent machines and have different Parameters affected by them.

Thats quite a good idea to cut the schematic down an only have triangle and square waves, makes for a smaller PCB to stuff inside things 

So Ebay is ok to purchase from?

I've never had any problems with buying components from ebay apart from the fact that'll it'd probably be a lot more expensive than just buying from a company like Rapid, especially if you buy from more than one ebay seller and have to pay multiple inflated postage charges

I've actually found eBay quite cheap to buy bits from, but you need to shop around.  Some companies will charge maybe £2 for a TL084!  Others will charge that for a pack of ten...

Yeah ive found a few rather expensive sellers, then theres the odd one or two that has everything in bulk for cheap. Its just a case of shopping around i think.
