Checkout this cell Jammer or we can say Dirty transmitter. A Dirty transmitter transmits junk within the cellular phone bands. This model is good enough to knock out pesky cell phones for about 10 to 15 feet, just perfect for a quite cup of coffee in your favorite coffee shop.

It’s not the smallest transistor out there, but the boffins at IBM have constructed the tiniest carbon nanotube transistor to date. It’s nine nanometers in size, making it one nanometer smaller than the presumed physical limit of silicon transistors

A man who helped make our world smaller died last week. As noted in the New York Times obituary linked below, Norman Krim didn’t invent the transistor , but he was a driving force behind its use, having persuaded his employer, Raytheon, to manufacture them on a large scale.

Yes, graphene is amazing and possesses many useful / otherworldly properties.

Andrew Angellotti has built and documented a DIY Brushless Motor Controller if you ever wanted to understand how a brushless motor controller worked or perhaps build your own this would be a great article to read. Once you have a good understanding of the heavy lifting electronics you should have a look at the second part of the DIY Brushless Motor Controller where Andrew goes over the code that makes the controller tick. “The half bridges use TIP120 darlington NPN transistors on the low side (emitter goes to ground, collector goes to the output/high side), with a 470 ohm current limiting resistor between the base and the input to the board

Where can you find Orson Welles, Marconi’s daughter, Alexander Graham Bell’s grandaughter, and inventors of the transistor and television? You might try To Communicate is the Beginning , a 1976 educational publication tracing the history of electronic communication, which AT&T recently decided to exhume from its archives of Bell Labs material. The 30-minute video’s just the first in a series, too, as AT&T’s website is already playing host to films about the origins of the laser and integrated circuit too, with more on the way

When I first took a look at this HDD Eyez project done by Jani ‘Japala’ Pönkkö over at MetkuMods I was thinking big deal, a few flashing red LEDs but the cap does some nice smoothing and results in a memorizing display. Via: Hackolog “We receive pulses from motherboard’s hdd led header

While you can’t buy a QUE proReader until summer it seems that you can buy the company. Well, maybe not you but someone with a few hundred million in the bank. At least that’s the way the Financial Times is framing a piece focused on UK investor Hermann Hauser, whose venture capital firm has a stake in Plastic Logic

It’s just been a little over a week since IBM researchers announced that they managed to open up a bandgap for graphene -based field-effect transistors, but they’re now already back to show off what that’s made possible: a 100GHz graphene transistor. What’s more, this latest record-setting transistor (which IBM hopes will one day replace silicon transistors) was made using processing technology that’s compatible with that currently used in advanced silicon device fabrication, which should no doubt help speed up its eventual commercialization.
