An easier way to do circuits

Is there a particular reason for loading all the images via https?

Even if you have an Arduino... you can't do everything with it... 
external analog components are still needed and this is where these can 
be very helpful.

why should I buy this? A simple breadboard is more flexible and if I 
have SMD components I can buy very cheap adapter PCBs from ebay.

Kalus,

You are right.

We are just trying to offer a kit to people that offers everything they 
may need for their projects.  The idea is we want them to use a bunch of 
our Simple Circuits and when they need a push button for instance, we 
will have that for them which can be easily integrated into their 
project rather than an "off the shelf" button.

Also even if you have an adapter board, there are still components that 
need to be added.  ie you cant just put an OP AMP IC down on a breakout 
board and expect it work correctly...  We have already done that work 
for you so it is simple to integrate into you projects.
