Régulateur avec disjoncteur pour train HO

thingiverse

Regulator for HO train with resettable fuse after power loss. Plan a supply of 12V to 15V. A voltmeter and an ammeter may be connected. If the ammeter is not connected, plan a bridge at the level of its socket. Plan four screws of 16mm in M3 for the face of the two parts At the end of printing part 1, you will need to make a pause in printing to lock in the screws (to facilitate heating the screws with a candle for a few seconds) Components: Diode 1N4007 x2 Resistor of 1/4W x5 (470 ohms, 2.2K ohms, 4.7K ohms, 10K ohms, 270K ohms) Resistor of 5W 0.82 ohms x1 Potentiometer of 1kohm x1 (to be soldered on it) Potentiometer of 10Kohm x1 LED of 5mm x2 (color of choice) Charged capacitor of 100uF 25V x1 Optional: charged capacitor of 10uF 25v x1 to delay the triggering of the relay Transistor 2N2905A x1 Thyristor BT149D x1 Relay HK19F-DC 12V x1 Darlington TIP142 x1 3-pin button ON - ON x1 6-pin button ON - ON x1 4-pin connector not of 3.5mm x1 2-pin connector not of 3.5mm x2
