Forget Me Not - Summary

Posted by kipe Oct 24, 2014
Foreword I guess my approach to this challenge was a bit different from other competitors. I didn't set out to solve specific problems, instead I wanted to implement my current system the Way I Want To™. In the meanwhile, it's not a bad idea to add sensors like the ones provided in the EnOcean sensor kit. Even if I didn't achieve all that I wanted to, I sure did accomplish a lot. And best of all, with hours to spare compared to the deadline   Hardware From the get go, my plan was to ...
Just a brief post with a video, I finally managed to code a basic UI for the current development phase. Sorry, don't have time or interest to cut the video right now, damn deadlines   Video shows the UI in action. Keeping with the idea of automatically searching the devices, I started with an empty database. Once the software is started (around 30 seconds or so, feel free to skip there), the 1-Wire bus is scanned for devices. After this, I push the rocker switch and it's added automatical ...
Thanks to Pekka Jäppinen for comments on the text.   BackgroundMy initial inspiration for getting into home automation was the fact that my dad started to build a house to “the middle of nowhere”. He currently works about 800 kilometers from the house with visits to the house being on average about every two weeks or so. As the occupation is so low, there’s no point in having the house at a constant +22 degrees Celsius. The energy bills would be massive, especially as ...
ForewordBeware, a lot of images, problems, failures (with a mix of success) to follow! Also, written quite hastily, so the text itself might be confusing The events following occur during 2 days. For some reason, my Linux decided that it doesn’t want to create ZIP files compatible with Windows. This delayed the PCB order for 3 or 4 days, but I finally received them on Thursday. Lucky for me, this was also the same day the TBS1052B-EDU oscilloscope arrived from service After a brief inspe ...
Finally!   The PCBs arrived yesterday, I've done the full assembly and it seems to be working. I'll post a longer update in the weekend or early next week, now I've got to try fix some problems with the PCB In the mean time, you can read about the properties of the PCB in the previous post. ...
ForewordAs I (might) have mentioned before, the initial reason why I got into home automation was the house my dad built in the middle of nowhere. The current system is based heavily on 1-Wire, which is pretty much a wired equivalent for EnOcean standard. 1-Wire bus uses only two wires and each device has an unique address, much like EnOcean. My goal for the design is to create an add-on for the Raspberry Pi, which will include all the stuff needed for the current system, with the addition of ...
First of all, sorry for my absence... A small list of excuses: a) been sick, b) been busy with school, c) haven't really got anything worth telling about done, ... ... ... z) lazy. Feel free to pick your favourite What I’ve done during the absenceCircuit DesignI finally got around to making my prize order, should arrive next week It took this long, as most of the stuff is components for my custom home automation add-on for the Pi. It'll include 1-Wire, RTC, 8-ch relay controller, "wat ...
Here’s my (quite) brief review of the oscilloscope received as part of the Forget Me Not -challenge, which includes using the scope to measure powering of the Pi B+ with a cheap DC/DC converter. The review is written as a flow of mind, so I'm fairly sure there is typos, mistakes etc. There's also some notes about using the scope I'd like input on, if someone has found a better way to do them... IntroAs part of the kit, every selected competitor received a Tektronix TBS1052B-EDU oscillosco ...
Just a brief post now, as I just managed to get my Python library hosted on PyPi and GitHub.   The GitHub page does get through the basic installation as well as a demo-script, showing a "proof-of-concept". The library can't be considered in any way stable, as I'm sure that I'll run into some problems when I'll start using it for real. From now on I'll be focusing on a demo-application by creating a Django-based web interface using the library.   So, basically you can checkout the l ...
As you may know, I’ve been working on a Python -library for the EnOcean Pi and sensors. At the moment of writing, the library is pretty much working, I just need to do more unit tests before I publish it. This is to allow easier integration of (hopefully many) pull requests. The basic stuff is supported by the library, receiving data from the sensors, parsing the sensors provided in the kit to human readable form and sending/receiving commands to the TCM 310. Network based sensor nodesI ...
I received my Raspberry Pi B+, EnOcean Pi and sensor kit on Wednesday. The Raspi and EnOcean Pi were easy to setup, as I expected, just do a normal install and disable the default serial console on Raspi and you’re ready to go. Other people have covered this topic already, so there’s no need for me to go over it. Unlike most of the contestants, I didn’t install any specific software to the Pi at first, just opened a serial console with ‘screen’ and pressed the le ...

Forget Me Not - Intro

Posted by kipe Aug 2, 2014
Hi, I was one of the lucky few to be selected for this awesome road test, and as I wait for the hardware to hack, here's a brief introduction to my project. The following is part application, part new text, so might be a bit confusing at times A small introductionI've been studying electrical engineering in Lappeenranta University of Technology since 2007. For the last couple of years I’ve been also working there part time, participating in energy measurement development for solar a ...
