Im having problems making this stupid Drawdio. Im currently in school for manufacturing engineering so I know nothing of electronics and im not the best at soldering so I thought I would try this to get a start. Not very happy at this point because I have about $25 in the stupid thing when a kit is $18 but at this point its just about finishing it.
Here is what I was trying to follow - http://www.parallelpoints.com/node/35
Seems that it is from a british site so many of the items they have referenced cant be found easily in the US but heres what I got
2 - .0022uf 100V Ceramic Disc Capacitors
1 - 10k Resistor
1 - BC559 which translated to a 2n4258 I believe
1 - 3VDC Mini Buzzer (I think this is the source of many of my problems...I cant find a sounder anywhere)
and finally I dont know how I screwed this up but I got the US equivalent of the BC548 which should be 2n3906 but I got the 2n3904 which is the NPN version appearently and I have no idea what that means or what effect that would have on this.
And if you watch the video how they make it sound with pencil lead or by touch or the sink with running water, I can do none of that. The only way I can make the buzzer sound currently is by touching the wires directly to each other. Please help me save this before I destroy it
