Why is it necessary to use pads for IC's when mounting them on vero board ? I have heard they get short circuited. Is that really the reason? If so why do they get short circuited ?
Thanx in advance

dont file it buy a small sanding block or make one
using cloth makes a nicer edge and cuts the oose spirals at the same time
also one you finnish sizing and cutting the tracks apart for component breaks
place the board on a flat surface
and stick white labels to it neatly

If the object is very shiny you will have reflections and depending on the dynamic range of the camera they (reflections) will be more or less unpleasant..
You can spread LED around the camera lens and to do this you can use a vero-board and connect the LEDs in strings of 3 in series and then 7 strings in parallel. This will give you supply volag

Strong interferences injected by the power supply have to be considered in electronic design. Electronic products are required to be hardened against it by EMI regulations.
