Transistor Crossover for Roulette Wheel Project
great! thanks guys! i have a 2n3904 from a previous project...i just need to follow the schematic about where the e,b,c goes right? or is the schematic symbol itself for the BC213L different?- electricman12

Transistor Crossover for Roulette Wheel Project
this circuit http://www.edutek.ltd.uk/Binaries/Prj%20Roulette/Roulette%20wheel%202.pdf needs a BC183L transistor...sadly this is a European transistor and I need an American crossover/equivalent... can anyone tell me what transistor is the EXACT crossover...or a transistor that would...- electricman12

Can someone check this Circuit?
so in the schematic linked above...i just need to switch the polarity of the capacitors? no need for re-evaluating the entire circuit right?- electricman12

Can someone check this Circuit?
Is there something I need to change on the circuit? because I am just about to solder it... also, while i was building I noticed that the negative end on the capacitor is hooked up to the positive end of the battery...is this ok? I really don't have much experience when it comes to this...- electricman12

Can someone check this Circuit?
hey, i got a transistor from a guy who told me it was a 2n4403 npn...which is the same thing as the 2sa1175 npn...but on the back of the transitor: there is a squiggly symbol (like an approximation equals to sign) and 330...and right below it says 4403...so did he give me the wrong transistor?- electricman12

Can someone check this Circuit?
I got this off of a site and i need someone to check the circuit before i finish buying all the parts (they are REALLY expensive and i cannot salvage right now lol) --circuit-- http://www.electronicpeasant.com/projects/ledlamps/ledorgan.gif --project site--...- electricman12

I cannot find an eletret condenser microphone?
I am trying to follow a guide that I found online and it requires an eletret condenser microphone...which no one seems to carry (my electronics shop, Fry's Radio-shack). I am still a started level guy so I really don't know what to look for when it comes to microphones so I was hoping one of...- electricman12
