Researchers have developed a microfluidic technique for fabricating a new class of metal-organic framework (MOF) membranes inside hollow polymer fibers that are just a few hundred microns in diameter. The new fabrication process, believed to be the first to grow MOF membranes inside hollow fibers, could potentially change the way large-scale energy-intensive chemical separations are done.

This instructable will show you how to build your own stopwatch to record multiple splits using an ATmega328 programmable microcontroller. When one presses the start button (or slaps the metal band in my watch), the screen displays the last lap for a second then continues the time on the next lap. It’s great for all […]

(Phys.org) —A recent article, appearing in the Journal of Urban Economics, authored by Penn State faculty member Brent Ambrose, Smeal Professor of Risk Management in the Smeal College of Business, and former doctoral student Moussa Diop examines the effects of subprime mortgage lending on the multifamily renting market. They found that subprime lending had a significant effect on rental defaults, which affected rental rates and property valuations.

Oculus has announced (via its website) that the first batch of preordered prototype Dev Kit 2s has left the company’s manufacturing facilities and are en route to distribution centers—they will begin shipping to people that preordered them starting July 14. Those in line to receive a kit will be sent a notification email—unfortunately for those that placed their orders later rather than earlier, the first batch will only be 10,000 units, thus, they will have to continue waiting—preorders were made for over 45,000 units

fun with ATMega328 and rtl-sdr Yesterday came to my attention a project that turns the Raspberry Pi into a FM transmitter. It is totally awesome and you should check it out. While reading an article about it, I thought to check ATMega328 and its fast PWM mode I showed you in the previous article for electromagnetic […]

Bacteria love to colonize surfaces inside your body, but they have a hard time getting past your rugged, salty skin. Surgeries to implant medical devices often give such bacteria the opportunity needed to gain entry into the body cavity, allowing the implants themselves to act then as an ideal growing surface for biofilms.

This is a simple 6 port USB device charger with a individual current monitor on each port. The charging current is indicated using RGB LEDs. Blue means slow charge (under 250mA), green means 250mA to 750mA, red means over 750mA, and purple means over 1500mA (for tablets). This circuit involves an ATmega328P (if you do hobby electronics, […]

Okay firstly the reason I wrote about the clock system instead of I/O ports or something else in this second post of the XMega series is simply because of the fact that without understanding clock configurations you won’t get what you want from your chip. Since XMega’s clock system is software-level configurable and complex at […]

Introduction Sound Bite The Automated Juice mixer is a juice mixing device that allows user to create desired drinks with up to four different ingredients through a user friendly interface. Summary Mixing juices can be a very tedious job.  We have created a juice mixer that allow user to mix drinks with desired amount and […]

After the success of my first nixie clock made out from a rosewood block, I decided to lose no time and to carry on with the next one. As some of you guys already know, or imagine, lately I’m indeed a little bit addicted to nixie-mania. I’ve bought many nixie tubes on eBay, and I experienced […]
