Medical coil on PIC controller . Further development of the coil on the PIC controller was this version. For therapeutic effect it also uses a second magnetic field, and now structurally it differs patawatomi food, which can be obtained not only from rasprostranennyh adapters , but also from any USB port: desktop computer, laptop and even smartphone. In the latter case, when the active work of the coil, the battery of the smartphone will be nothing more than the included screen. All these measures helped not only to unify the food, but away from the noise in pretty contaminated 220V, and to make a coil cleaner. . In addition, in this version of electronic components has become smaller, more optimized connection between them, and the generation field at VT0 now has the best characteristics for a high modulation frequency and 5V supply. Otherwise, the principle of action and coil work exactly the same. . Принципиальная схема лечебной катушки с модуляцией PIC-контроллером Details. The following is a list used in the unit circuits, diodes and two modes. In parentheses are possible replacements: . All capacitors circuits — ceramic or polypropylene, with a nominal value of deviation of no more than 5%. Any low power resistors with a nominal deviation of not more than 20%. The coil itself is wound in any of the ways suggested here or here. . The file for the firmware of the microcontroller can be downloaded from here. About how it is stitched, read the article: "Flash PIC controller is just". User management to the coil, see here. . Constructive. For coil Assembly will fit a small plastic box: with a window under an indicator or with a transparent top. Box of metal — not suitable! The scheme is simple, so her details can be placed on the breadboard. If the VT0 is used 2SC5200, then it can not put on a radiator, if BD0 small radiator required. The circuit of the coil is connected via a two-core wire 1.5-2m directly to a USB connector, to two extreme conclusions . Some of the Assembly steps shown in the following photo:.

Setting. If the circuit is assembled correctly and the microcontroller stitched, the entire coil starts working immediately without configuring. The only thing that you need to adjust the current from the power source. It is adjusted by trimming resistor R0 should be in this version of 250mA at maximum frequency on the display. .  . 1 2 3 4 . .
