>>12161517Fine, Anon. I'll share with you my idea.
I want to combine the precision of electronic detonators (which have an electronic time delay element) with initiation by non-electric means.
Non-electric detonators are initiated by a shock-tube which consist of a long tube with a thin layer of explosive mixture on its inside wall. The tube is initiated by electric spark of sufficient energy. The shockwave travels through the tube and when it reaches the detonator, it initiates so called explosive train, which consists of a pyrotechnic delay element (usually some metal powder mixed with oxidiser) and primary explosive. The pyro delay burns with constant speed, although it can be really whimsical. The primary explosive initiates secondary explosive and the detonator explodes (detonates).
My idea is to convert the thermo-mechanical shock from the shock-tube into an electric current by means of piezoelectric element. The current "created" this way would supply energy to the electronic time delay element and would therefore allow for a precise detonation time.
This things (high precision and vibration control) are super-critical in mining and are of the most importance. The biggest problem though is that I'm really bad at electronics or electricity in general.
The min. current needed to fire a detonators depends on its current class. If you have electric (electric detonators are a third type of detonators and they do not have electronic delay element. They have traditional pyro delay element inside and are initiated by electrical means. Also they have so called electric match inside or a fusehead) detonators of class 0.2A, the min. all-fire current is 0-8 -1A.
There you go. Now you know my genius idea.
