Barnes & Noble is putting on a Mini Maker Faire next weekend at stores across the country. As part of the event, Windell will be at the San Jose store on Friday, Nov. 6 at 1 pm with The Annotated Build-It-Yourself Science Laboratory.
Ken Shirriff has written an excellent exploration of the 741 op-amp, including decapping a metal can package AD741. There’s a very cool interactive viewer so that you can click on the components in the schematic or on the picture of the die to see what each one is and does.
…The 25pF capacitor in the 741 has a very small value but takes up a large fraction of the chip’s area. You can see the capacitor in the middle of the die photo; it is the largest structure on the chip. …
Our very own XL741 is referenced in the footnotes, too.
You’re invited to our annual open house!
When: Thursday, November 19, 5 pm − 9 pm
Where: Evil Mad Scientist Laboratories
175 San Lazaro Ave, Suite 150
Sunnyvale, CA, 94086
From the archives comes one of our favorite food projects: Halloween Cuisine: Sweet or Savory Specimen Jars.
What good is a specimen jar if you can’t serve it at dinner? The contents of the jars should be genuinely edible, made out of real food. Plastic snakes and spiders are right out.
