A mostly .NET but also some other cool techs blog. Power, I2C and DMX. The first board for my home automation project needs to provide everybody with Power (5V DC). This is the main purpose of this board and because this is a very basic requirement it’s the first to be described here. But this board handles two more jobs:. Create 5V DC from input voltage of 12V DC. Convert a 3,3V I2C bus to an I2C bus capable of speaking with 5V components. Driver for the DMX signals. I use a simple SN75176 differential ...

A mostly .NET but also some other cool techs blog. Accessing git repositories with hg (mercurial) tools. Once upon a time we switched from subversion to Mercurial. Or hg) as source control system. We choose hg because at that time the tool support on windows was much better for mercurial as for git. Not all of us wanted to go the console-only approach and I still love my TortoiseHg. Very much. We are very happy with our hg setup and have no intension to move away from it. The Hg-Git Mercurial Plugin.

A mostly .NET but also some other cool techs blog. Push buttons as input. To control the lights in a house or in my own apartment switches and buttons near the doors in the wall are a very useful thing. But first of all the signal from the buttons needs to be received by my micro controller. I will use 12V DC for all buttons, to avoid higher power like 110V or 220V AC. To protect the electronics and don’t get trouble with long wires at all I use optocouplers. The signals itself are received by a PCF8574 ...

A mostly .NET but also some other cool techs blog. How to catch SqlExceptions and don’t get into trouble about aborted transactions by SQL Server (or: how is it possible that a transaction is only executed halfway). It looks like the transaction was only executed halfway or like a broken rollback. But we were using Microsoft SQL Server and I could not imagine the existence of a bug that does such a thing and wasn’t already fixed to the current version. Id (PK, int, not null). Data (varchar(50), not null).

http://www.ticklishtechs.net/2011/01/05/do-it-yourself-home-automation
A mostly .NET but also some other cool techs blog. Do it yourself: home automation. For my new apartment I imagine some nice (or nerdy) infrastructure things. Since the apartment is currently building and I can decide how to do the wiring: we will get CAT7 Ethernet nearly everywhere for gigabit Ethernet. We will get a lot of power outlets, HDMI cables from the stereo to the TV and to a potential place for a projector and so on. Control every light in every room of my apartment. Optional (or later on):.
