Datasheet Digest 🧐

Optocouplers are fun! They can be used to isolate two circuits up to 5,000 volts! Check out the Datasheet Digest Podcast at DatasheetDigest.com! Thank you for watching.

A thread about neat 555 facts and stories. Doing some research in the 555 timer. Did you know that the 555 timer was originally released in both a standard DIP-8 package along with a metal can package? Does anyone have one of these? 🧵🪡

Today I got a hilarious and wonderful Christmas surprise in the mail from @MakeAugusta! Not in a million years would I have been able to guess what was in this package when he told me something was headed my way. David does pcb event badges and design - all USA made - 100% worth checking out!

Feeling bored. Might destroy a transatlantic cable later. Idk. - Dr. EOW Whitehouse (probably)

@lauriewired neat!

What operating system does your AirPods run? Sounds like a weird question. Until you realize you have the equivalent processing power of an iPhone 4 in *each* ear. Bluetooth audio SoCs are seldom talked about, but a fascinating field.

Twenty years ago, the Internet was a work in progress.

@geerlingguy I just got one and haven't noticed an improvement from my M1 MBP. Could you suggest something that will make the improvement of evidence to the everyman?

M4 efficiency is stunning. First machine I've tested getting over 5 Gflops/W with HPL, and in fact it goes beyond 6 Gflops/W... with fan only spinning up to a quiet 2500 rpm. Maybe this is why Qualcomm abandoned their marquee Dev Kit—it is thoroughly trounced by M4.

oh boy

Werner Siemens named his custom-made cable laying ship after his dear friend Michael Faraday. That's really nice. He and Faraday worked together solving issues in telegraph cables in the middle of the nineteenth century. CS Faraday en.wikipedia.org/wiki/CS_Farada…

Have you ever wondered how some parts got their part number? 1N4001? 2N2222? That story started over 100 years ago. Learn more in this article from @digikey Magazine. The Rise of Designators: The Semiconductor Part Designation Origin Story: emedia.digikey.com/view/539611426…

Gerber is a familiar name to many in the electronics design and manufacturing industry. It is the name given to the manufacturing automation instruction files generated by printed circuit board (PCB) layout software. allaboutcircuits.com/news/celebrati…
