High speed rotary encoder reading

Does anyone use the Raspberry Pi to read rotary encoders at high rpm? I have some HEDS-5500 encoders on the back of some nice DC motors. I want to build a small robot and use the encoders to have drive wheel feedback. I wrote some very simple code to read the encoders using interrupts with wiringPiI...

Re: Wifi AP, Non Realtek WIFI dongles?

I have a Realtek 8188 and I have been able to setup as an access point. I used apt-get to install all components (although there were a few config file modifications from the out of the box setup). My system can even switch back and forth between access point mode (to connect directly to the pi) to ...

Re: Wifi Hotspot/Access Point and Client - best solution

You may consider looking at a project I have done. The Pi boots up and goes into 'master' mode, where you can connect to the "RPi" access point with whatever device. Once connected, your device is on a network where your raspberry pi is the gateway. You can control the pi by pointing whatever softwa...

Wi-Fi with no ethernet cable: connections stop working

My setup involves a headless Pi on WiFi only. You need to use it at multiple locations, so static IP isn't an option. When the Pi boots, it is configured as a router in Wi-Fi master mode, and you connect to it with your mobile device and point your browser to the gateway address to reach the web ui....
