LM555 Timer IC (8 Pin DIP)

These are well made. Granted, you can go to the dollar store, and if you buy enough calculators and timers, you'll identify a brand that you can reverse engineer out many of these parts for pennies. But for convenience and quality, this is outstanding. No defects after using hundreds.555's, op-amps and regulators are the heart of most electronics today. If your electronics or circuit analysis texts cover op-amps before transistors, get a new book!Regardless of how experienced you are with 555's and op-amps, we can all use a little help and fun, so here are two very tiny, inexpensive "manuals" that will do your heart good while playing with these two amazing components:1. 555 Timer Applications Sourcebook Experiments (Howard Berlin) and2. Timer, Op Amp, and Optoelectronic Circuits & Projects (Forrest Mims III)These are only 120 pages or so and $10 bucks or so, but they will greatly enhance your enjoyment of these components. I probably don't need to mention Forrest Mims, as he's a legend!Happy engineering!

Got item ok I make starships and jewelry and my wife makes quiltsWe work for the family jewelsThe flashing lights I call my starship motor and sells for about 20 bucksWhen the lights flash toward the center from each side make a patternReplaced with the proper set of magnets they should produce motion in space

I just realized, I didn't receive the IC

I needed those timers for my class! well I bought a dozen and everything worked great! none stopped working so far... I even accidentally overcharged one of the timers with 9 volts and got pretty warm, but still worked after that.

The IC was fried on arrival.

I am real happy with item.I have been able to complete all project with product.I highly recommend to everybody.Great item to have on hand.

its what the doctor order
