Dual USB Voltage And Current Tester

₦ 8,250

This simple device can be used to operate or test servo motors. There are 3 modes to check servos;

  1. Manual mode: turn the knob
  2. Neutral mode: make the servo go back to the neutral point
  3. Automatic: window wiper mode: make the servo swing like a window wiper in the biggest angle. Push button to change between modes. Lights indicate mode.

You can connect 1-3 servos simultaneously. It can also be used to check the operation of any servo motor whether fitted or not.

Description:

Dual USB Voltage and Current Tester

This is a great volt and amp meter to see the load used by modules and microcontrollers. You can easily see, as an example, how much power is consumed by your microcontroller project.

Use the USB Charger Doctor to measure the working voltage and current output for any USB port and project. This plastic dongle plugs between a USB device and passes the data lines through. There’s a 0.05-ohm resistor in line with the power pin that is used to measure the current draw. The Doctor’s digital display instantly reads the numbers out for testing devices such as chargers, cables, and cell phones.

You can use this device from 3.5-7VDC input voltage (although most USB devices tend to hover around 4.75 to 5.25) and up to 3A of current. It displays both voltage and current readouts. It’s a very handy tool for testing USB devices, checking load levels, and debugging battery chargers and boost converters.

Specification:

  • Voltage range: 3.3V-9V
  • Current range: 0-3A
  • Voltage display: red
  • Current display: blue
  • Output: 2 USB
  • Size: 52mm x 34mm x12mm

    0.5 Plastic Gear Kit – 46 Kinds

    ₦ 4,500

    Description:

    This is an assorted pack of 46 different commonly used plastic gears

    Gears play a huge role in much of the technology around today. For example, car engines, drills, lathes, mills, CD/DVD Drives, printers, mechanical watches, children’s toys, in fact, gears are almost everywhere there are motors and engines which produce a rotational movement.

    Nylon Spur gears have significant advantages over their metal counterparts in several ways. Nylon Materials used in gears are, in general, engineering plastics such as polyacetal (POM) and MC Nylon which is essentially polyamide resin. This allows for weight reduction in machine design. They are quiet, absorb vibration and do not need lubrication.

    Applications:

    • They are used to reverse the direction of rotation, for example when selecting reverse in your car.
    • Gears are also used to transfer rotational motion to a different axis.
    • Gears are used to alter the speed of rotation which in the same way can be used to alter the end turning force or torque available

    Package Includes:

    • 1 x 46Pcs Plastic Gear Assorted Kit Set with Various Gear and Axle Belt and Pulleys for DIY Car Robot Project
