Re: Wanted Digital Audio Out Adaptor

Couldnt this signal be pulled from I2S via GPIO? All you need is to put this signal against an RCA Female adapter?

Setting up WIFI via Wireless access point on RPW

Has anyone been successful in using the Raspberry Pi W (RPW) to dynamically boot to an access point when wifi settings need updating? This is similar to what another user is doing via bluetooth and an app , but I have been mostly following http://imti.co/post/145442415333/raspberry-pi-3-wifi-station...

Re: WiFI AP with Webserver to configure wifi

I am looking at doing something similar. The (untested, still in progress) steps are: setup hostapd to make the pi an access point run a webserver (nodejs express) with small webpage capable of updating /etc/network/wpa_supplicant (and rebooting) run a bootup process to test for wifi continuity, and...

Re: OLED Display 128x64 python library

Can anyone help me with ideas of why I can get this LED to work fine with python libraries (per instructions here), but not with node (https://www.npmjs.com/package/oled-js-pi)?
I suppose that rules out the hardware/os issues mentioned in this thread?

Re: Setup WiFi access via Bluetooth

This also seems like a generic feature that would benefit a lot of people (and myself!). I thought there would have already been a solution out there. I'm also working on a headless "box" that needs to be deployed by end users on their own wifi. I'd be happy to give this ago, I'm more software/firm...

Re: Controlling a car with Node.JS

Per other comment, highly recommend verifying the "blinking led" first, as you might find the dc motor pulls more amps than the pi can put out.

You might have to control the motors via a transistor or other mosfet type.
