USB battery charging rev. 1.2: Important role of charger detectors

The USB Specification Evolves Other than generous helpings of coffee, what helps industry decrease time to market, drive down cost, and focus more of the design cycle on innovation? Hint: standardization. By defining protocols and operating characteristics, standards have impacted all aspects of technology: device package sizes, pin outs, data and communication interfaces, software drivers, connectors, ESD ...

Exar’s USB serial bridge devices

Exar has announced a new family of USB to serial bridge devices for industrial applications. The XR21B142x family interfaces with RS-232 or RS-485 serial networks. The XR21B1420, XRB21B1422, and XRB21B1424 provide 1, 2, and 4 UART channels respectively. The XRB21B1421 provides a single channel UART and uses the native operating system HID (Human Interface Device) driver. The XR21B142x devices are fully comp ...

USB Game Pad With Tilt-accelerometer Mouse using an Arduino

Make a game pad with an accelerometer inside! This project tutorial will show you how you can convert a console game pad into a USB keyboard mouse for playing games on your PC. The USB game pad can be used with nearly any software, such as a MAME emulator, game, simulation software, or for custom user interfaces. We'll start by turning the buttons of the game pad into keyboard buttons, so that pressing 'up' ...

Lithium Battery Solar USB – iPhone – Arduino Charger

One of the most fun and useful projects on instructables is to create your very own solar USB/ iPhone charger. They're not overly difficult to make, nor are the parts overly expensive or hard to find. For the most part they do a rather good job of charging up small gadgets. Mostly. The big flaw in the DIY solar charger world are the batteries. Nearly all the designs on instructables (including all of my des ...

Arduino USB

LOG: Made a correction/modification Step 3 and added a picture step 5. So many Arduino users have RBBBs(Really Bare Bones Board (Arduino))  or Anarduinos or Boarduinos that could use a USB interface to program and power them but don’t want to spend $15-20 for a USB BUB or FTDI cable. This Lazy Old Geek is one of them. Theory: Most Arduino clones are programmed with a PC using a USB port. Theoretically, they ...

TI aims at audio with low-noise low-power op amps

Description   The OPA1662 (dual) and OPA1664 (quad) series of bipolar-input operational amplifiers achieve a low 3.3 nV/√Hz noise density with an ultralow distortion of 0.00006% at 1 kHz. The OPA1662 and OPA1664 series of op amps offer rail-to-rail output swing to within 600 mV with 2-kΩ load, which increases headroom and maximizes dynamic range. These devices also have a high output drive capability o ...

Turn your Arduino Uno into an USB-HID-Mididevice

While building an Arduino Uno based Midi-Controller for Ableton Live, I came across the HIDUINO project ( http://code.google.com/p/hiduino/ ). It allows you to turn your Arduino Uno (or any other device using an AVR-USB chipset like the 8u2) into a driverless HID/Midi device. It's much more comfortable than using a software based serial to midi converter which has to run in the background all time. The only ...

Assembling the ZIFduino USB 1.2

The ZIFduino, for all intents and purposes, is an Arduino with a ZIF socket. It's geared toward those that want to do prototyping on the platform, but then move the ATMega chip to a stand-alone environment. The pin layouts are exactly the same, so it should be compatible with most shields designed for the Arduino. The PDF of this instructable can be downloaded at bittyware.com/instructions/Assembling-the-ZI ...
