The toy shop from which I bought the magnet
Button magnet is very convenient when we want to attach our circuit boards or any not so heavy boxes to some metal surfaces.
I was working on a project in which a PCB containing coil tracks has to be attached to the rotor disk of a motor inorder to test the inducive sensor used for measureing the speed or the rotor. We have designed the PCB such that the it can be attached to rotor disk using a magnet.
But there was a problem, we dont have a suitable magnet. Lot of vendors are available online, but they will take some time for the order to be delivered. So I went searhing in the hardware shops around Kanthaswamy temple, near pookkada, parrys market for a button magnet. In the hardware shops only black ferrite magnets were available. After searching a lot i got the shining neyodymium magnet from a toy distributor shop. There was only one type available(10mm dia x 1mm thickness) and it was perfect for our requirement.

Beyond Compare and options

Beyond compare is one of my favourate diff tool. It has lot of options like
  • compare folders
  • comparison with code syntax highlighting
  • edit and merge available from the diff viewer
  • options to choose what to compare(while compare two c source code files, we can ignore difference in comments)
  • binary comparison, etc etc
these are a few features out of hundreds..
Recently I was trying to get a portable version of beyond compare from internet. But later I relaised that the installer itself provides an option for portable installation. Even the lisence will be available in the portable copy.

It will be handy to have a C compiler which is ready to be used without installing.Mingw is the windows version of the open source gcc compiler suite. It can be used to compile both C and C++. It is possible to use the Mingw from one pc to another by copying the C:\Mingw folder, but there is some problem regarding the folder path settings and update functionality.
Portable mingw from portableapps.com is a portable version of mingw compiler which contains batch scripts to invoke the commandline with the environment variables set and also has an update batch script. Previous versions of this package even has the msys environment.
Here I have uploaded my copy of Mingw Portable installation. In which the larger file is an older version, but contains msys.
