ImmersionRC Vortex Race Quad - Oculus R/C. 12V Step Up / Down Voltage Regulator (605070) This powerful step-up/step-down regulator efficiently produces a fixed 12V output from input voltages between 3V and 30V while allowing a typical output current of up to 2A when the input voltage is close to the output voltage and offering typical efficiencies of 80% to 90%.
Its ability to convert both higher and lower input voltages makes it useful for applications where the power supply voltage can vary greatly, as with batteries that start above but discharge below the regulated voltage.The flexibility in input voltage offered by this regulators is especially well-suited for battery-powered applications in which the battery voltage begins above the desired output voltage and drops below the target as the battery discharges. Without the typical restriction on the battery voltage staying above the required voltage throughout its life, new battery packs and form factors can be considered.

In fact, the biggest problem is keeping up with the stuff you really want to remember. It’s so easy to read an article or discover a new webapp you like, only to forget it and never find it again. Fonts and icon packs seem to be the easiest for me to forget; I’ll find ones I love, and then somehow never be able to find them again later. There’s no reason you have to lose stuff you find online, though. Even in our fast paced society with new tweets and notifications coming in all the time, you can still keep up with the stuff you like online.

Self built MC HCK for $5 - mchck.org. From the beginning, the MC HCK was conceived to be not only cheap to produce and sell, but it was also conceived to be buildable at home, at a low cost.
In this post, we’ll show how to build a MC HCK at home. Getting the Parts All required and optional parts are listed in the BOM. Let’s quickly go over how to get the required ones. The MC HCK boards can easily be ordered from the usual suspects in China. You can sample a compatible MCU directly from Freescale. Passives These are common parts, and many people will already have them in some way or another. 100nf decoupling caps Cost: $1.85 for 100 2.2μf regulator caps Cost: $1.89 for 20 33Ω resistors Cost: $2 for 100 1kΩ resistors Cost: $0.99 for 50 LEDs Cost: $0.99 for 15 buttons Cost: $6+$1 for 50 Assembly Check out this soldering stop motion sequence taken while hand soldering a MC HCK: Software Once your MC HCK boards are soldered, use the wiki to get started with the software library.
ITEAD Studio 2Layer Green PCB 5cm x 5cm Max. Very good service, quality PCB and price Highly recommended for professionals and amateurs electronics technicians.
PCBs are very well made I will do more PCB. Very cheap, good quality This is my first not professionale PCB made in the Far East. Good shipping time to Italy with the regular postal mail (three weeks from order to delivery). I am satisfied Quality is good, delivery can be little bit shorter, generally, I am satisfied. Very decent pricing, Fast shipping Delivery was surprisingly quick and the quality was superb. Excellent quality, price and service I've already ordered 5 times and will do more as I need new PCBs, I wouldn't think of anyone else for my PCB needs.
Very good service, quality PCB and good price. IoTgo - Open Source IoT Platform.
