Data acquisition with PoKeys and logging with Raspberry Pi

By |March 22nd, 2018|Other|

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) [...]

Arduino Mega2560 and PoRelay8 relay boards with CAN bus

By |March 16th, 2018|Home automation, How to, Other, PoKeys|

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 [...]

Raspberry Pi 3 and PoRelay8 relay boards – Part 2 (CAN bus)

By |February 13th, 2018|Other, PoKeys|

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 [...]

PoKeys meets ThingSpeak – reporting data to IoT cloud

By |January 17th, 2018|Other|

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 [...]

Raspberry Pi and PoRelay8 relay boards – Part 1

By |December 21st, 2017|Home automation, How to, Other|

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 [...]

Encoder Threading with Mach4 Lathe and the usb cnc controller PoKeys57CNC

By |January 24th, 2017|CNC, CNC controller, CNC Machine, Other, PoKeys|

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 [...]
