Left to right : Pulse1, Pulse2 and Voltage adjustment
I did however test the dual pulse before tackling this job and I am very pleased with the results. It works better than expected and you can use any one of the two pulses by turning anyone off or use both. At this moment you get two bleeps when you use the dual pulse and one bleep when you use one pulse, it is very fast though and sounds more like a long and a short bleep. It's things like this that needs a little attention.
I will try and have it finished by next weekend and hopefully get it on youtube.
