About Material

Portal 6W 0.8W Solar Panel



This compact 80mm x 40mm Polycrystalline Solar Panel can be used to build portable solar chargers for cellphones and small DC batteries. It can also be used to power small electronic loads like garden lights, staircase lights, or even a small solar toy.
Each panel is rated for 6V 100mAh, because of the small size it can be easily connected in series to increase voltage rating or connected in parallel to increase current rating.
Note: Appearance and Size may differ.

Specifications of Solar Panel

  • Material: Polished
  • Power: 0.8W
  • Voltage: 6V
  • Size: 70x70mm
  • Weight: 12g

RS-555SH DC Brush Motor

        The primary magnetic pole and brush are assembled on the stator of a brushed DC motor, while the winding coil and commutator are assembled on the rotor. The brush and commutator allow the dc power supply's electric current to enter the armature winding and produce armature current. The main magnetic field interacts with the magnetic field produced by the armature current to produce the electromagnetic torque, which causes the motor to revolve in order to drive the load. read more

    18650 Li-ion 2200mAh Rechargeable Battery 



            18650 battery is a Li-ion rechargeable battery with a 2200 mAh Battery Capacity. This is not a standard AA or AAA battery but is very useful for applications that require continuous high current or high current in short bursts like in cameras, DVD players, iPod, etc. A 18650 cell can be charged and discharged up to 1000 cycles without much loss in battery capacity. They are safe to use, environment friendly, and have long battery life. It comes with high energy density and provides excellent continuous power sources to your device. It should be used with a protection circuit board that guards the battery against over-charge, and over-discharge of the pack, and avoids over-current drawn. Important: Please note that this cell is a copy version and is not original, hence the capacity and performance of the cell might vary based on charging and discharging parameters in your application. We do not recommend this for power-critical applications. You can check out Original Hongli 18650 cells for demanding applications. Simply glue the wires to the terminals to use the cell in any circuit, and you can quickly swap out spent cells by using 18650 battery holders. Li-ion batteries must be handled carefully because they are flammable and volatile and shouldn't be handled violently or punctured. Additionally, avoid overcharging and discharging past a certain point since gases that have built up within might cause explosions and fire. So whenever utilizing Li-Ion batteries, always utilise the protection board. View additional cells here. 3.7V Rechargeable Li-Po Battery, 9V Hi-Top Battery, and 9V High-Watt Battery

    220 ohm, 1/4 watt register with 1% tolerance

    This is a set of 10, 220 ohm carbon film resistors with 1/4 Watt and 1% tolerance. Each resistor has strong leads and easy-to-read color coding for breadboarding. In addition, the leads are about 0.55 mm in diameter and are constructed of tin and copper plated over steel wire. This allows them to stand well with repeated inserts into the solderless panels.

    Features of 220 ohm, 1/4 Watt Resistor with 1% tolerance

  • Highly Reliable 220 ohm Resistor
  • ±1% Tolerance
  • Power Rating: 0.25W
  • Package: Axial
  • Mounting Feature: Through-hole
  • Composition: Carbon Film Type
  • Excellent Heat and Humidity Withstand Performance
  • Long Life
  • Automatically insertable

1n4001 diode



        A diode is a device that allows current flow through only one direction. That is the current should always flow from the Anode to the cathode. The cathode terminal can be identified by using a gray bar as shown in the picture above.
For 1N4004 Diode, the maximum current carrying capacity is 1A it withstands peaks up to 30A. Hence we can use this in circuits that are designed for less than 1A. The reverse current is 5uA which is negligible. It can withstand a reverse voltage peak up to 400V.

Features of 1N4007 diode

  • Average forward current is 1A
  • Non-repetitive peak current is 30A
  • Reverse current is 5uA.
  • RMS reverse voltage is 280V
  • Peak repetitive reverse voltage is 400V
  • Available in DO-41 Package
