Zasilanie z zasilacza 10-24V stabilizowane 7809 na 9V, potem przez diode prostownicza na 8,4V. Opornik 10ohm stanowi kontrolę prądu do lądowania akumulatora 2S Li-Po 7,2V (tu zasymulowany przez kondensator 1F). Mogą to być dwie połączone szeregowo identyczne baterie z telefonów komurkowych. Przy akumulatorze mniejszej pojemności należy zmienić opornik na 15-20ohm (akumulatory 800-1500mAh), a przy wiekrzej pojemności można zmniejszyć wartość opornika do 7ohm, co spowoduje podniesienie prądu lądowania do 1A (TYLKO PRZY AKUMULATORACH >= 4000mAh!) Następnie stabilizowane jest ono przez przetwornice (bezstratnie) lub stabilizator 7805 (stratnie) na 5V do zasilania arduino. Stabilizatory 78XX roboczo zastapilem stabilizatorami z diodą zenera. Power supply of 10-24V stabilized power supply to 9V 7809, then by the rectifier diode to 8.4V. Resistor 10ohm a control current to charge the battery 2S Li-Po 7.2V (here simulated by capacitor 1F). They can be connected in series two identical batteries of mobile komurkowych. With smaller capacity battery should be changed to 15-20ohm resistor (batteries 800-1500mAh), and at a larger capacity can be reduced to a value of 7 ohm resistor, which will raise the charging current 1A (only the batteries> = 4000mAh!) Then it is stabilized by converters (lossless) or stabilizer 7805 (lossy) at 5V to power the Arduino. Stabilizers stabilizers 78xx tentatively replaced the zener diode.
