Robottino Android con led ad alta luminosità

thingiverse

Remix of the Android Robot. Added high-luminosity LEDs in the eyes, activated by a microswitch on the head and powered by two miniature AAA batteries (with a resistor in series to lower current and increase lifespan). Modified battery housing by adding an extra battery (high-luminosity LEDs require a power supply between 3.18 and 3.3 V), achieving a total of 4.5 V. As shown in the circuit diagram, the LED draws a current of 1.32 mA, while the voltage drop across the resistors brings the operating voltage at the LED terminals to 3.18 V (in line with LED specifications, preventing damage). In the C-shaped enclosure created on the foot block, insert a contact lamina to electrically connect the poles of the two batteries, and pass the negative pole through the hole at one end. In the top part, insert springs or contact laminae to create the + and - terminals of the power supply. Post-Printing. Custom Section
