Such wonderful information.im trying to make a simple transistor radio.but so far i couldnt..i dont have radio amplifiers like MK484 or else.im trying to make 5 transistor as a darlington pair(simple NPN 2n3904).when i play the circuit with LED in it.it becomes very sensitive.but when i attach inductor capicitor to it.it doesnot gives any audio output.please explain where can i put the tank circuit (to base?) and also explain what is a feedback coil.what does it do,where to put it at collector?

Try Googling "regenerative receiver" for your feedback coil. You might prefer "crystal radio" to that, though, and searching "transistor amplifier" comes up with lots of good circuits. Good luck!

Where could you find real instructions how to build silicon microchip?

@iamsnail

I'm not sure these days, but if you google Jeri Ellsworth, she's a young woman who has designed chips. There my be something that you could learn from her story.

Nice job. I'm still trying to understand the transistor. Why is something so simple so hard?

[acmeschool]

I wouldn't be surprised if the Atomic Physicists weren't still arguing over how they work. I just concentrate on how they act, rather than how they do it.

"we'll hold on for a few seconds, in the case you wanna pick up notes". I loled.

Great series by the way!

waht bout ben frklin?

in the intro the dog is so funny

[Sexualeddrbob]

Uninformative at all look on my channnel at my vids way better...

[agent008chico]

In my limited time exposed to electronics this is one of the best explanations I ever had on transistors. If finally made me understand.

[pfloydguy]

wow, amazing explanation. Thanks.

[rpttc]

Its a great work my friend, the topics you have described are realy a great help for beginers. thanks a lot for nice work.

Keep it up

haha suckers i can pause the video, have more than few seconds now

For all you guys having trouble remembering the table or are still looking of a "cheat sheet", I wrote a free program to help you out. Here is the link to the quick tutorial on how to use the program. The download link is in the description. youtube.com/watch?v=nolRA9ZmK-­U

the transistors in chips are used to form logic gates, which preform the actual math involved in computing.

[MSTLOM]

The arrow in a schematic of a Transistor or Diode drawing is not really to indicate current flow. The arrow is just to indicate the Anode(+) and Cathode(-) aspects of the Semiconductor. This helps the Technician see how the Semiconductor is Forward or Reverse Biased. It just so happens that the arrow points in the direction of “Conventional Voltage Flow” while “Conventional Current Flow” is the reverse direction,. from Cathode to Anode. This is for those who seek clarity is all.

2 dolors for a microprossesor mine cost 400 bucks!
