Warning This Project Has Changed Again!

Still working on a new prototype hence no pix yet.

WARNING: ELECTRIC SHOCK HAZARD Working with high voltage is dangerous! It only needs about 5mA through the thorax to stop the heart, and 500VDC is quite capable of doing this. Therefore never poke your fingers into a live circuit! Adopt a proper safety procedure and follow it every time – before the circuit may be safely touched, switch off the mains and pull the plug. Then make sure that the HT voltage has discharged to at least 50V; if necessary discharge with a resistor (not a screwdriver!). The proper industrial procedure includes shorting the HT with an earthing strap, you could do this but don't forget to take it off before turning the power back on. (Alternatively a high value discharge resistor, say 1MΩ, may be permanently incorporated into the power supply.) This procedure follows the acronym S.I.D.E. – "Switch off, Isolate, Discharge, Earth". Don't cut corners!
