Logic Friday

Today I wanted to quickly calculate a truth table for a simple boolean equation. Whilst this can be done very simply on paper it becomes tedious with lots of inputs.

A quick Google search found “Logic Friday”, available at sontrak.com. Boolean operations can be described using logic gates, truth tables or an equation.

Cooking with gas, my first SMD board

My first bunch of boards arrived back from BatchPCB and I’m really impressed.  Great printing for the silkscreen and a really professional looking product.  One of the boards I ordered was a breakout board for the SMD PIC 18F2321, the first surface mount board I have tried.
