Talking Electronics Sites previously shared the new book The 200 pieces prepared for transistor circuits I mentioned. Author of this type continues to free.
Many of the circuits simple circuits 555 in the book is set up with very few elements oscillators, timing, LEDs, motor control and you have to practice a lot more

Air Core, Toroid Coil Calculator Programs
The coil has an inductance (expressed in Henry and submultiples – “L”), a ballast to the passage of alternating current (expressed in Ohms – “X”), a resistance to the passage of direct current (“R” – in Ohms) , a factor of merit.
L ‘inductance is the ability to store electrical energy in an electromagnetic field. The ballast is an electrical resistance element that offers to the passage of an alternating current having a certain frequency. The factor of merit (or quality) expressed with the letter Q is the ratio of the reactance (inductive in this case) and the sum of all the losses associated with the decrease in energy in transit
