Replacing a laptop screen

Broken Laptop screen
That moment when you open your laptop, press the power button and you’re greeted by the rainbow colours of a cracked LCD screen.

With the design of modern laptops it would appear that this would mean the end of the device as the screen is secured inside the plastic housing with no obvious way to replace it. Fortunately with a little know-how it was relatively easy to source and replace the screen of my Toshiba Satellite C660D-1HK.

RISC OS Portsmouth Show 28th September

I had not been to a computer show featuring RISC OS for a few years so when I found out that there was to be one in Portsmouth I made sure I was available. The last time I had been to a show that featured RISC OS was the Acorn User show at Wembley Exhibition Hall in 1992 and I was not sure what to expect. Things have certainly changed during the last 21 years and Acorn no longer exist as a company but their legacy lives on in the ARM processor and RISC OS.

Multi threaded LabVIEW execution

Using four different RS485 serial ports to communicate with four data acquisition devices, each with four channels it should be possible to sent commands to the each device in turn while waiting for a response from the first. This will greatly reduce the time required to poll all channels. So why is it taking over 40 seconds for all channels on all ports when it takes less than 10 seconds to poll all channels on one device. LabVIEW should be able to run each port in a separate thread.

Running LabVIEW as a Windows Service

Today I finally got around to using Visual Studio to create a Windows Service that will call a LabVIEW executable every 10 minutes to log temperature to a database.

We have been running a LabVIEW application as a service using a free version of FireDemon but found today that our corporate anti virus software marks the executable as a Trojan. Getting an exception for this will take ages so after referring to google I found an article on MSDN with the title Windows Services: New Base Classes in .NET Make Writing a Windows Service Easy.
