    Free sample chips!

    There was one site on the first page of this topic(says that it only passive devices next to it).  I like to see what I am ordering too, so I dont use mouser or digikey, I use www.allelectronics.com.  I was thinking today about how radio shack turned from an electronics store to a crappy...

    How many people here scrap old electronics?

    I just take stuff apart because I know somewhere down the road I will be looking for something that radio shack doent have, and dont want to order online(I start off with a $5 list and end up with $50, I cant stop!).

    How many people here scrap old electronics?

    Am I the only one that takes apart broken or stuff for the garbage and takes the chips, transistors, capacitors, resistors, chokes, coils, and wire(if there is enough)?  I used to take apart old printers that we had and just take the LEDs, but now I take just about everything(except SMT).  I...

    Free sample chips!

    I dont really need chips, I need more passive stuff.  Do any of those companies offer resistors, capacitors, pots and that stuff?  I am also looking for some transistors and diodes that I cant find at my local radio shack (radio shack sucks).

    Astable multi vibrator, some help?

    I have been using the schematic for awhile now and its working fine.  When both buttons are pushed, both guns on the game shoot at the same time and same speed.  If I was to take out the variable resistor, would I replace the link between the 5v and R3,R4 with a 100k resistor, just a wire, or...

    Astable multi vibrator, some help?

    Oh sorry, I forgot to post the values.  Here they are R1(variable resistor) - 100K R2, R5 - 470 Ohm R3, R4 - 4.7K Ohm R6, R7 - 1.8K Ohm T1, T2, T3, T4 - 2n222(or any other switching transistor)

    Programing an IC, how does it work?

    I was thinking, how do you just plug an IC into a programer, put some stuff on it and it works?  Whats physically inside of an IC?
