We deal with advanced multimeter with PC interface ( USB option)
It seems like everything plugs in to your computer these days, and this digital multimeter is no exception. This auto-ranging multimeter will test AC and DC voltage and current as well as capacitance, resistance, frequency and even temperature. It features a large, easily readable display for use in the field as well as the ability to connect to your computer for data logging, processing and analysis. It has all of the basic functions that you expect from a good digital multimeter including continuity check (with buzzer), diode test and data hold. Data logging and analysis software is included on a mini-CD and you can also download it below.

Note: The included CD contains all versions of the software. The version that has been tested to work with this unit is version 3.0. You can also just use the download link below.

Note: This meter does have a USB interface, but it's not clearly RS232. The meter needs the proprietary software to function and you cannot simply read the data directly without a driver and the software.

Product Details:

Standard BLDC 30 amp ESC Electronic Speed Controller with Connector is specifically made for quadcopters and multi-rotors. It provides faster and better motor speed control giving better flight performance compared to other available ESCs.

STANDARD 30 amp ESC Electronic Speed Controller can drive motors that consume up to 30A current. It works on 2-3S LiPo batteries. The onboard BEC provides regulated 5V(2A max draw) to power the flight controller and other onboard modules. This is useful to control our brushless motors with a 2-3S LiPo (make sure the motor doesn’t draw more than 30A).

If you are wandering to build a drone and don’t know what will be the best ESC for you then worry no more, we have got your back. At Robu, we have everything for you to get started with your drone project.

1. Overview
IR Remote control is a combination of Infrared transmitter and Infrared receiver which contains 4 relays and 1 Fan Speed Control through TRIAC, which can be controlled wirelessly. This makes the unit very easy to operate and integrate with existing systems. The remote control operate the corresponding relay on the receiver board, i.e. Light 1 operates relay 1, Light 2 operates relay 2, etc. Relay contact can control any equipment in momentary mode (On till key pressed) or Latch Mode (Toggle on each key press). Each relay has indicator LED showing current status. The transmitter uses a modulated 40 kHz carrier to transmit data about which button is pressed. This method is used in all IR remote controls as it offers a high degree of noise immunity against interfering light sources. At the receiver end the IR receiver module extracts the data signal from the carrier.
This active HIGH output is used to operate a relay via ULN2803 which is an octal transistor array.
Special Feature:
Memory backup - Memory backup saves last condition of relays if power has gone with FAN speed also.
Custom Build Remote Control with Sleek match

Illuminated LED Eye Loupe

Description: When working with small parts, sometimes you need magnification and some extra
light. This is a monocle we use regularly in our production facility. It has a 10x lens with a
working distance of about 1-1/2". This product is very similar to our illuminated monocle
magnifier, but there is no attached aluminum-core headband.

This loop magnifier set itself apart in our eyes because of the little LED on the side. Trying to
view SMD connections is hard enough - the LED on the side is a huge help for those close up
inspections. The LED provides sufficient light at the working distance.
LED battery comes installed.
