A simple FM transmitter circuit powered by a 9 volt battery pretty small SMD resistors used in PCBs
Your offer is very simple compacts zhuchok transmission signal with a range of 100-150m good sensitivity and low current consumption. scheme consists of a bass amplifier for the first transistor and the proper frequency generator in the second. transmitter divided transitional capacitor that allows you to set up a cascade separately.
At that shows the value of all the details and transistors! Reel contains 5 turns enamelled wires 0.35mm to send a diameter of 3.2mm (rod of the handle or auger).Setting devaysa boils down to the installation shown in the pattern of voltages through appropriate resistors, and then check the current consumption – it should be about 10mA antenna – a piece of wire 40cm. Here you can see the bug assembly factory performance
Balancing Li-ion Li-Polymer Batteries Battery Balancing Circuit Balancing Li-ion Li-Polymer Batteries Battery Balancing Circuit Many projects are usually carried out with a single battery. serial battery connection is required for higher voltages if the charger does not have balancing, deterioration occurs according to the capacity of the batteries, the batteries that are loaded early are overloaded and deteriorated, and this problematic battery, the charging circuit for charging the batteries prematurely finishes charging before the other batteries are charged. For example; We need 12V in our project 3 Li-ion batteries in series with full charge 1 battery voltage 4.2V in this case 12.6V charger for 3 batteries needed We have started to charge our batteries and each battery has a different capacity and occupancy rate Some batteries have an early filling the middle battery in the schematic reaches the limit value of 4.2V and the others are not fully charged in this case the total voltage will not stop charging until the 12.2V charge cycle is 12.6V.
