Re: Bluetooth to xbee bridge, or is MicroUSB possible?

You can use either Google's ADK or MicroBridge to make an Arduino and an Android device talk over USB.

Hope this helps.

Re: usb host shield - 5v regulator getting very hot.

I had the same issue plugging in my ZTE Blade. I left my Arduino spewing logcat messages out over serial for about eight hours and when I came back everything was still working fine, so don't worry.

Re: Google ADK/ADS non-Arduino Mega2560

@PhatBob: nothing, really. There's already a port to the Fez, and I think YTai will add support to his IOIO pretty soon, too.

Re: ANDROID ADK Compatible Arduino Mega Board

In the mean time you can use the $25 USB Host shield that Sparkfun already sells. http://romfont.com/2011/05/12/google%E2%80%99s-open-accessory-development-kit-on-standard-arduino-hardware/ Personally this is my favorite board so far: http://diydrones.com/profiles/blogs/new-diy-drones-product-previe...

Re: Google ADK/ADS non-Arduino Mega2560

You don't need the kit, you can buy a standard Arduino and Oleg's USB host shield. Here's a write-up on how to do it: http://romfont.com/2011/05/12/google%E2%80%99s-open-accessory-development-kit-on-standard-arduino-hardware/ If you don't have a 2.3.4 device, you can use the ADB protocol instead: ht...

Maybe OP can simply print a circle of the correct diameter and use that for reference?

Re: Nordic nRF24AP2 - 1-channel ANT Connectivity IC

It's meant to interface phones with external sensors, might be pretty fun for wearable electronics, body area networks, or just wireless ...

Re: Simple LUFA USB capable board / bridge, like Teensy

@souplogic: the first implementation of the PS3's USB sploit was on AVR, I believe using a at90usbkey. These were then quickly sold out worldwide, as well as teensy and others. Chinese manufacturers have since taken up production and with no way to differentiate, prices have been driven down to the ...

Re: Simple LUFA USB capable board / bridge, like Teensy

For those who are looking for just a an Atmega16u4 or Atmega32u4 on a board without anything, you could always just get an 7$ PS3 jailbreak dongle from DX (http://www.dealextreme.com/search.dx/search.jailbreak). If you're looking to buy a teensy, try this: http://www.dealextreme.com/p/designer-s-min...

Re: PNI Spacepoint RM3000 9-axis sensor+magnetometer+Kalman filt

@paul.c: if you haven't already, have a look at http://code.google.com/p/imumargalgorithm30042010sohm/. I'm currently using it in conjunction with an IMU3000-EVB and an Ardupilot. The algorithm is much less computationally complex than the Kalman filter yet equal in quality, quaternion based, and do...

Re: USB host dev boards

@mcuaust: the UNO's chip only supports USB slave, so it can connect to a host (i.e. your PC), but you cannot connect slave devices to it.

Re: USB host dev boards

@mcuaust: the reason Arduino is popular I think, is that it's a bit like a swiss army knife. It has loads of I/O such as GPIOs with input capture and PWM, I2C, SPI, UART, ADCs, etc. The fact that you can pretty much hook anything up to it is a big advantage. To me, adding USB to the list just seems ...

Re: USB host dev boards

@mcuaust: USB stands for 'universal serial bus' :) There's loads of stuff you can connect over it but most importantly, it's a standard used in commodity devices. So instead of getting an expensive $30 bluetooth-serial bridge you might be able to get a $3 dongle from DX and use that instead: http://...

Re: InvenSense MPU-6000 - tri-axis accel and gyro in a chip

The problem with Invensense products is that although their hardware looks nice enough, their support isn't great. No proper documentation and no proper code for working with these chips :/
