Versatility of PoKeys device makes it well suited as a component of an environment monitoring system. PoKeys device functions as a data acquisition point, as many different sensors can be easily connected to it. Acquired data can be stored directly with PoKeys software logger or sent to local or remote server (like ThingSpeak IoT service) [...]
PoRelay8 board with 8 relay outputs can be connected to any device, which can communicate over I2C protocol (see example for Raspberry Pi and PoKeys). If 8 relay outputs do not satisfy your demands, additional 9 boards can be daisy-chained over CAN bus, even with long cables between boards. Here we present an example of [...]
First part of this blog (you can find it here) was about connecting and controlling single PoRelay8 board with Raspberry Pi. Relay board and Raspberry Pi were communicating over I2C bus. Setup in this example has two limitations: First, I2C bus was developed for communication between devices on same PCB and can be used only [...]
Late in December Xively IoT platform has announced retirement of its free service Xively Personal, support for which was already integrated into our Ethernet PoKeys devices. One of possible alternatives is ThingSpeak IoT platform. Free version offers up to 3 channels, each can contain 8 data fields. Number of messages is limited to 3 million [...]
PoRelay8 is a relay board and features 8 relay outputs. Up to 10 boards can be daisy-chained over the CAN bus for up to 80 additional outputs. In previous blog (Using PoRelay8 with PoKeys and long cables) we wrote about connecting PoRelay8 relay board to PoKeys57U device over the PoExtBus. The PoRelay8 is an updated [...]
Porelay8 board allows expanding the number of outputs of the PoKeys device by using the PoExtBus. It features 8 relay outputs. Up to 10 boards can be daisy-chained over the CAN bus for up to 80 additional outputs. CAN (Controller Area Network) bus is a robust bus standard initially designed for automotive use to allow [...]
Fix We fixed which was causing software crashes when selecting and opening file in Recorder.
The latest release introduces new features and improvements Low pass filter on analog channels We're introducing low pass filters to smooth out signals on analog inputs. This is very useful feature to get rid of noise and improve trigger stability. Filter on analog channel Improvements Improvements of trigger Improved stability

The organizers would like to thank all the participants that they devoted the last few months to preparations for the competition, which they also attended. Special thanks also [...]
Digital Machinist article: Encoder Threading with Mach4 Lathe and the usb cnc controller PoKeys57CNC I was excited to hear that threading with Mach4 Lathe and the usb cnc controller Pokeys57CNC with an encoder was now working. I just had to try it, since I had mixed success with index only threading in Mach3 Turn. I had [...]
