PSD Distance Sensor & Speakers

The PSD Distance Sensor is not easily available in the US is there similar models to this one?

Something from either http://Digikey.com , http://newark.com , http://www.mcmelectronics.com/ , or http://www.mouser.com/

Could these work for speakers?

This looks like it could run the speakers

So are they the same parts? GP2Y0A21YK0F and the one originally posted GP2Y0D21YK0F

Awesome thanks will have to get to ordering soon.

Does anyone know how many Raprio's have been built and sold to date?

The distance sensor can be found here:
https://www.sparkfun.com/products/242

There is a pigtail for it at the bottom.

Is the distance sensor to attach to the rapiro board or the raspberry pi?

Also i found these to use with the speakers: http://usd.dx.com/product/6979-lm386-20-times-gain-circuit-audio-amplifier-module-blue-901179381#.Uxkp4_ldWSp

I've gotten TTS working, but am having power issues with wifi dongles.

The sample schematic shows JP1 for sensor and another for I2C but I think on the PCB it's listed as a different number above the I2C.

What wifi do you have. The cheap one's on the bay or anyone that sales Raspberry Pi's have compatible.

I have gotten quite a few from this seller http://www.ebay.com/itm/USB-Wireless-Adapter-2-0-802-11n-g-b-2-4GHZ-150Mbps-Wifi-WLAN-nano-mini-/151020085653?pt=US_USB_Wi_Fi_Adapters_Dongles&hash=item23297fa195

EDUP with the same form factor work just as well. If you want one that can act as an access point search raspberrypi.org forums they would do well with Rapiro running it's own web server.

The one I linked to on the bay should have the RT5370 chipset and the instructions below show it compatible to make it a hotspot.

I already tried to connect a distance sensor to rapiro. When I finished soldering the I²C and JP1 connectors to the controller board, I recognized that the A6 and A7 pins of ATmega328, that are proposed to connect a sensor, do not provide digital IO capabilities. Meaning you only have 2 analog inputs on the sensor connector. So I had to use the I²C port (A4 and A5) to connect my distance sensor. (I used the HC-SR 04 and fixed it between the 'eyes' using a rubber band.)

I'm using this wifi adapter: http://www.adafruit.com/products/814

The pi randomly reboots after a few minutes of use or high traffic conditions. Seems to be power related. I am using a 12V5A power supply but have ordered a 10A one and will see if that makes a difference.

SiggieBooh - how many connectors does the sensor you used have? The one suggested (that i linked above, which actually has a mount build into the mold, just inside the chest area) only has 3.

The HC-SR04 has 4 pins: VCC, Ground, Trigger and Echo. It is much bigger than the Sharp sensors, so it does not fit into the desired place. To perform a measurement you give a 10microseconds high pulse on the trigger pind and then measure the duration of the echo pulse. For such a sensor I need digital IO logic at the microcontroller pins. Unfortunately I damaged my sensor, so I'm currently waiting for a shipment from Hongkong. I will report about experience with it.

The Wolfson Audio Card, produced in collaboration with Wolfson, the premier mixed-signal semiconductor and audio solutions company, offers Raspberry Pi® users similar flexibility to a PC soundcard to capture audio alongside their camera, and experiment with stereo digital capture and playback.

I want to hack one of these onto Rapiro hope it's an easy patch

Hi, I am using this amplifier
http://www.robot-r-us.com/sound-voice/3w-mini-audio-stereo-amplifier.html
and these speakers
http://www.robot-r-us.com/components/speaker-0.5w-8ohm.html

It works nicely.
