Dual Polarity Power Supply

This supply gives both positive and negative outputs. Appropriate Fuses should be used to protect from fire hazard and overload of transformer.

Dual Polarity Power Supply

The Filter capacitor C1 4700uF has an impedance of Xc = 1 / (2 * 3.14 * f * C) which comes to 0.6 ohms at 50 Hz. The impedance of the load at 2A for 24V is R = V / I that is 12 Ohms which is more than 20 times the impedance of the capacitor at 50 Hz. That means less than 1 / 20 of ripple current will flow thru the load. The Regulator also reduces the ripple a little.

Surgical Tools useful for Manufacturing

Small Boards, SMT circuits and hybrid electronics need special tools. The soldering and handling require some tools and custom jigs which can be custom designed. 

Some product are mass produced, some tools for managing and working on Tiny PCB's and parts may not be available in the market at an affordable price.

Electronic Product Production Manufacturing

So affordable solution can be created, the jigs are supplemented by surgical tools. These are the Clips and Tweezers that a doctor uses when he conducts an operation.

Surgical Tools useful for Manufacturing

Let use see one here an Hemostat Clamp and other tools at P J Tool and Supply

Call it Forceps, Tweezers or Pliers. These tools, both the bent/arched/curved one and straight are useful.

When you go to a Surgical Supplies Store, Buy some Filter Paper, capillary tubes and a spirit lamp as well. These can find a lot of good use in the ultimate quest for the God Particle. Beat the Swiss to it.

Electronic Fifteen LED Roulette

The following was submitted on July 11th, 2007 at 12:47AM (PDT).

Message: I want to combine Ne555 with 74154 IC.The indication of the outputs must be shown with LED's but up to so far it need 15 outputs ,is it possible the way i did? if not i will need your assistance

Mail from CY

Electronic Roulette

See these circuits you will get an idea, Using CD4514 is also possible.

Virtual Robotics Lab – building a mobile robot

Robotics is the Magnum Opus of Engineering, It combines Electronics, Mechanical, Computing and also the toughest science know to mankind.... Wireless Networking!

Ethernet Networking itself is complex, A self healing, hack proof and plug-play Wireless Router has to be the first step to make safe robots.

From Virtual Anthropomorphic Robots to Androids

Just imagine a Wireless Router or even a Internet Router as easy to tune as a FM radio, no entering numbers, no admin with browser. Just keep it in a room and all gadgets and computers form a fuzzy network, all by themselves. The very idea of technology is to make things simple, cost-effective and efficient.

The real need of robots now is to avoid Humans in Hazardous Environment. Right from Outer Space to working in a Plant with Toxic Chemical Gases, Even machinery and equipment that injures the limbs or damages the eyes.

Virtual Robotics Lab - building a mobile robot

Virtualization in Robotics -

If workers can wear a coat of sensors with force feedback actuators, they can control a semi-automatic robot in Real-Time. This enables a worker to navigate a robot into a hazardous environment, perform an upgrade or make repairs. An accident or mishap will damage the robot and it can be easily rebuilt or maintained.

The robot is automatic and will have reflexes defined by software. The wireless networking will connect the Robot mechanically to a human in a safe enclosure. This makes the Worker present virtually inside the Robot, because he is connected by optical, aural and mechanical-muscle feedback-sensors. This will create Virtual Anthropomorphic Robots for Industrial use and may help to finally develop Fuzzy Robots or Androids, which is still in the relm of science fiction.

K-12 Experiments in Robotic Software
The ROVer Ranch is an interactive, Web-based robotics workshop for assembling the hardware and instructions for a software robot to perform a mission in a virtual environment.

Animatronics is a multi-disciplinary field which integrates anatomy, robots, mechatronics, and puppetry resulting in lifelike animation. Animatronic figures are often powered by pneumatics, hydraulics, and/or by electrical means, and can be implemented using both computer control and human control, including teleoperation.

VirtualRobot is a freeware software suite
Its beginning, on 1998, was motivated by the need of a remote graphical application for programming, monitoring and simulating multi-robot cells on the control system GENERIS (Generalised Software Control System for Industrial Robots) developed by European Commission Joint Research Centre.
