Simple pathway lighting that will provide illumination for that path during the night. Extension for that Solar garden Light. The torroid is bifilar wound. The Torroid is 10mm and Cat 5 cable is wound round the same.
Solar power panels of three.5 maybe hard to procure using 2 2V panels in series might be used. Should you choose use 4V panel then suggest you add another diode in series with 1N4001 to decrease voltage to contain voltage towards the battery.
The characteristic voltage for any white LED is 3.2V however the addition from the torroid offers the boost they are driving the white LED. If you fail to procure battery as suggested you should use 600 mAH battery then don't exceed 3/4 LED’s.
