Hand vein patterns are unique and universal. Vein pattern is used as biometric feature in recent years. But, it is not very much popular biometric system as compared to other systems like fingerprint, iris etc., because of the higher cost. For conventional algorithm, it is necessary to use high quality images, which demand high-priced collection devices. The two approaches for vein authentication are repeated line tracking and maximum curvature method. Currently we are working on maximum curvature method. Here we are putting forward the new approach for low cost hand dorsa vein pattern acquisition using low cost device and proposing an algorithm to extract features from these low quality images which are used for personal authentication. 

Order Code : RDL/PVA/13/001/V1.0 

The robot is controlled by a mobile phone that makes call to the mobile phone attached to the robot in the course of the call, if any button is pressed control corresponding to the button pressed is heard at the other end of the call. This tone is called dual tone multi frequency (DTMF).

Order Code : RDL/CPO/13/001/V1.0

Break to fit. 40 pins that can be cut to any size. Used with custom PCBs or general custom headers.

Order Code : RDLFBS/13/001/V1.0

Burg Strip Male with Right Angled bent pins. Total of 40 PINs with standard 0.1 inch pitch. Can be broken easily into any number of pin groups.

Order Code : RDL/MBSR/13/001/V1.0

These are small DC Geared Motors which are very comparable to hobby servos for power, at a fraction of the cost. Perfect for low cost Robotic Kits and applications.

A DC motor is a mechanically commutated electric motor powered from direct current (DC). The stator is stationary in space by definition and therefore its current. The current in the rotor is switched by the commutator to also be stationary in space. This is how the relative angle between the stator and rotor magnetic flux is maintained near 90 degrees, which generates the maximum torque.

This is an IC base for 18 Pin IC's. This base is very useful for your circuit because if your IC burns out you can easily change the IC without the need of desoldering.
