Crystal Oscillators are the Time Base on a wristwatch or a home clock, analog or digital, Mechanical clocks have become rare due to the Maintenance and Accuracy. Some crystals can change dimensions on a electric force, some generate electricity on Mechanical Strain. Ceramic Resonators – “The ceramic componets are made of high stability piezoelectric ceramics that functions as a mechanical resonator. The frequency is primary adjusted by the size and thikness of the ceramic element.” In the mechanical gramophone a metal needle and a horn would amplify the sound. When Record players came, the use of magnetic pickups made the [Read More ....]

The Apple Home Computer set a revolution in computing and these Personal Consumer Computer developments led to IBM making the IBM PC, which became a standard. Various associated Technologies and Components including the Windows from MS evolved from this IBM PC. From XT to AT, then from 286 to 586, the evolutionary trend continues. The Speed: GHz, Space: GB and Software: Linux-XP, have grown rapidly. The other vital things Interface, Networking and Power Consumption moved a bit slower. So some suggestions on the New Desktop for Small Office and Home Standard, that is crucial in the present computing scenario. Enterprise [Read More ....]

The PC is now an economic and common equipment at home or office. To interface it to the real world is a step in learning Automation and Robotics. In Automation we have both Industrial and Home. Experimenting with Home Automation and Building PC based Instruments is the first step. An Electronics card needs to be interfaced by Serial, Parallel or USB Ports. Some Small VB6 Software Source for Virtual Electronic Instruments are available here for Learning and Developing. You can Read More about it at my Data Interface Circuits section Computer Data Interface These Programs use a component Inpout32.dll from [Read More ....]
Moving Coil Voltmeters, Ammeters and Resistance Bridge were combined to make AVO Meters a field instrument. They were used alongside hand cranked meggers, current-potential transformers. Valve based Electronic Instrumentation with Nixie Tube Displays cannot be forgotten, taking readings from nixie tube displays can be more satisfying than reading a plain LCD. The Vacuum Florescent 7 segment display array was popular till very recent times in some cash registers, calculators. Talking of cash registers read this story … “Busicom (Nippon Calculating Machine Corp changed its name to Business Computer Corporation) was a Japanese company that owned the rights to the first [Read More ....]
Many times we cannot carry big or expensive test instruments to the field, so we have to have a troubleshooting tool kit. Continuity testers, Logic Probes, DMM, Clamp Meters etc.. It also is sometimes required to build a quick jig or fixture with electronics to troubleshoot, simulate a problem or to test the reliability or aging of components and systems. Here you need to be cost effective, fast and innovative; and build a simple system with available, affordable or procurable resources. Hence a bit of circuit design, firmware and software are essential skills for production engineering. You can troubleshoot and [Read More ....]
