    Simple Arduino Home Energy Meter

    I wonder if anybody has built something like this for a three-phase powered house (400V). I presume it is at least three times as complicated :)

  • Display Temperature and Humidity and upload to ThingSpeak

    I just built something like this yesterday using Rbpi zero and a DS18B20 plus a USB WiFi module. I chose to use DS18B20 instead of DHT11 because I do not need humidity and have found the temperature accuraty more reliable. The total cost (without general cables) was ~ $18 consisting of the Rbpi zero, a MicroSD card, a DS18B20 and a WiFi module. The system can, of course be extended with DHT11 modules and several Dallas chips.

    The Ultimate PVC Quadcopter

    Can anyone explain what 1" Schedule 21 PVC pipe means physically? I cannot find any reference table as to what it would be in the metric world. 1" is ~25mm but what is the wall thickness of the pipe used? Fractions of an inch are ok, of course.

    Thanks, I tihnk I have now something to do during the winter. Next summer we will see what our local brown bears think about a DIY quadcopter :)

    Breathe New Life into an Old Computer

    Please stop repeating that nonsense. People have used SSDs with success for years and know the benefits. As for myself I have been using SSD drives only for five years now, currently I own almost ten of them, all of them in daily use (three workstations, one laptop, one server, a few external cases) and NONE of them had failed so far. If you care to read some of the torture tests you could read that any SSD will very probably last several decades in normal daily use. I have used the cheapest Kingston and Sandisk models without one single problem. I would NEVER again go for old-fashioned hard drives even though I have used them since early 1980s and sold hundreds of them in my computer shop days.I am using HDs in just two places: a 4GB tertiary backup station and my secondary backup (a m...see more »Please stop repeating that nonsense.

I would NEVER again go for old-fashioned hard drives even though I have used them since early 1980s and sold hundreds of them in my computer shop days.I am using HDs in just two places: a 4GB tertiary backup station and my secondary backup (a mirrored NAS). Once 2TB SSDs become available the days of the NAS disks are gone as well.There is quite a bit of statistical data as well if you are willing to search for it. The hard drives today are getting more and more unreliable and have already lost the reliability battle.What you are writing might have been valid 5+ years ago but not today. Please stop spreading nonsense.
