Model Railway Automation with Raspberry Pi.

The popular and inexpensive Raspberry Pi1) tiny PC offers some interesting I/O like I2C and GPIO. Because the I2C bus is a common and standard one, the idea to use it for Model Railway automation was born in 2013. Together with Peter Giling, who lives in the Netherlands, we have developed a range of modules for use with Model Railways. And I am Rob Versluis, living in Germany, the founder and main developer ...

IBeacon Entry System with the Raspberry Pi and Azure

In late March I went to a hackathon at Universal Studios. We created a system where guests could bypass the queue line by completing a series of tasks that would lead them around the land the ride is in where the average completion time was 66% of the current ride wait time. This system pulls people from the queue line while providing the incentive of a more rich experience, less down time, and potentially ...

Raspberry Pi Sega Mega Drive/Genesis II Case

I received my Raspberry Pi and decided I needed a case. I didn't have much available to me in terms of laser cutters, 3D printers or woodwork skills etc. so I thought laterally. I'd previously had the idea of using the Pi as an emulator so I thought, "why wouldn't a Pi fit in a Mega Drive case?". About an hour and half later of taking my old Mega Drive II apart and thinking about the best ways of keeping ev ...

Cheap solderless reset button for Raspberry Pi

This is my first Raspberry Pi. I've bought it as an XBMC home-theater box (and a "we'll see later on what else"). One of the annoying things I've found out right away was that it didn't have a reset button. You can politely shut down the thing from software, but how do you turn it back on? This is especially important in the beginning when you're still "breaking it in" and have to reboot often (or even cras ...

Tank Day 9: Power to the Pi

Last time around, we proved that the Raspberry Pi could indeed be integrated into a Heng Long Tiger I RC tank, and so control its functions. That’s a significant achievement, but there’s plenty more to do. Firstly and most importantly, we can’t yet drive the tank around because the Raspberry Pi is still dependent on a power source, keyboard input and video output – each of which is a cable connecting the ta ...

Raspberry Pi and I2C devices of different voltage

After my recent posts on using the MCP23017 I/O expander with the Raspberry Pi several people have queried the connection of an I2C device running at 5v to the Raspberry Pi’s 3v3 I/O. The reason why this is safe in this case is that on an I2C bus the clock and data lines are open-drain lines that are pulled high and devices on the I2C bus pull them low to communicate, in this case the Pi is pulling the line ...

AUTOMATIC DOOR OPENER CONTROLLED THROUGH SLACK

The post was originally posted on http://www.visuality.pl/posts NodeJS Based Office Door Opener with using Raspberry Pi and Slack. Sesame At one of the hackathons we decided to automate our door opening process. It was a pain to do this manually because lots of clients and delivery guys (especially at lunch times) were visiting us. So we have decided to make a door opener that will be controlled by Slack. W ...
