Hi,

You know those jumpers you find on computer motherboards well I'm looking for something like that, something really small. Anyone know if Digi-key sells anything like that. I did a search on "jumper" but I couldn't find what i was looking for.

Also I'm looking for some suggestions on some interesting Ics like the 555timer or 4017 Decade counter. Something like that something easy to use. Maybe an Ic that does some interesting sound related stuff or An IC that can "fade" an led on and off gradually.

I am looking for an Ic that can drive a seven segment LED display. So I could make a clock using the display.

thanks for any suggestions.

thanks ivancho but i was thinking of those jumpers that have 3 pins. they are like 1cm or so in width. I have one on my motherboard thats used to start your computer up with the BIOS screen. thats the jumper i'm refering to.

If you are talking about the pins that are attached to the board, those are usually headers. The standard 0.1 size are very common and digikey has many different types. In any case, a 3 pin 0.1" is digikey part wm4001-nd. Hope this helps.

Like the ones I told you about, they are called Shorting Blocks or Shorting jumpers, that is why I thought you were refering to. :D

Those other ones are headers and uou can buy them in a long strip ans then snap them to size. Jameco has this headers for cheap
