DIY monitor for Smartmeter
It has been a while since my last post. But I have been working on something I waited for so long. I have a real smart-meter (instead of my previous Iskra ME162 digital meter that has no I/O ports that are active (infrared) or any other useable way to read out the meter without breaking the seal)
PHP Solarpanel monitoring via Rasperry PI
As promised some time ago here is the post explaining how I use my Raspberry PI to monitor my SolarPanel Output. I use PHP for this mather. When I bought my solar panels back in november 2012, I knew that i wanted a Raspberry to communicate with the Solar inverter and read out the values to store them in a database. My preferred language to use was PHP. I will show you how I did this. First a summary of the equipment I used : 11 x Sharp ND-R250A5 High-performance […]
DVB-T Fun with a Raspberry PI – Weatherstations (Part 3)
Welcome back to part 3 already with DVB-T Fun with a Raspberry PI. In this part I will show you how you can profit from receiving all the data of your neighbors fancy wireless weather station data and use it for your own benefits. Weatherstations with wireless sensors are very common and cheap now-a-days. Prices vary from 80 euro to a few hundred euros. What most of them have in common is the use of the LPD433 (Low Power Device 433 MHz) or unlicensed ISM band/SRD bandfrequency to transmit the […]
DVB-T Fun with a Raspberry PI – Airtraffic (Part 2)
Hello and welcome back! Part 2 of the series “Fun with Raspberry and DVB-T” In this series we are going to use our previous setup to receive aircraft information with dump1090 . What aircraft is flying where? What altitude? Where is it heading to? All this information from the airplanes near the reach of your antenna can be grabbed from the air (1090Mhz) .. and all this with your little Raspberry and a cheap DVB-T Dongle.
DVB-T Fun with a Raspberry PI – Playing Radio with Linux (Part 1)
In this chapter : Playing Radio with a Raspberry PI and a DVB-T Dongle. You have probably heard about the cheap little USB Dongles made to receive digital Television and / or radio. They come in many shapes and forms (and prices) but you can find some cheap ones around the net. You can score one for around 10 € easy on ebay.
2013 , A good year for Solar panel owners
2013 was, i want to believe, a good year for the my Solar panels (2750kw) . The year brought a lot of sun (for Dutch concepts). With a total of 2527.01 kWh and a total run time of 4227.56 hours I saved an equivalency of 200 gallons (757 litre) of gasoline, 1.5 Acre of forest and 0.668 tons of waste sent to the landfill. More about my solar panels and how I read out the statistics from my inverter in a later blog. If you have any questions already you […]
Expanding and upgrade my storage on Synology to Raid 1 (Part 2)
I promised to come back to the 2nd part of my post. After the checking of the consitency was done I expected to do 1 more step, expanding the drive to it’s full capacity. So when I woke up this morning, the first thing I did was checking my precious disks. Big was my surprise that the Synology DSM software already decided to use the full capacity of the disks. So, tadaa.. Fully mirror RAID 1 and 4TB (3,6TB effective) for my movies and stuff. I love it.
Expanding and upgrade my storage on Synology to Raid 1 (Part 1)
I have a Synology 1512+ which is doing it’s job perfectly for my needs. Let me explain what was my situation and how it’s now (and how I did it) .. just in case whenever you cross the same situation. The Synology 1512+ is a 5 bay diskstation running Linux as base. On top of that OS Synology made it’s own “Disk station Manager” called DSM. All these actions where performed with DSM v4.3.3810 Update 3. Any older version of DSM might not have the functions I described and used […]
