Circuits & Electronics
Warning! Some of these designs use a mains power supply, thus treat the whole circuit as being at mains potential. Disconnect before making any adjustments etc. If you need to use an oscilloscope or other grounded instrument for debugging, the circuit MUST be operated through an isolating transformer. The finished design MUST be enclosed in a suitably insulated case, and if switches are used, they must have a mains rated insulation.
This information is provided 'as is'. Readers should only attempt to build mains rated designs if they are competent at electronics assembly and understand the dangers of mains voltages. No responsibility is accepted for any damage, injury or death (however serious) caused by anything remotely connected to this website.
