All of the Clocks and Timers on this site have had a cosmetic face-lift: for modern browsers that support HTML5 you can now click anywhere on the 'face' to make the display go 'full-screen'.
The Resistor Colour Code Calculator has been updated to show the colour codes for actual resistors, automatically chosen to be the nearest 'standard value' to a given resistance.
Electronics engineers can now calculate the resistance of a current-limiting resistor to run an LED at the correct voltage and current.
The Every-Purpose calculator, that can calculate all text formulae has had another update, allowing you to update equations even after the first calculation is complete, so you can easily investigate the effects of changes, or correct mistakes. Further updates will follow later this year, so please accept our apologies for any rough edges.
