Measureall Workbench Test Instrument

This was a Student Project of mine, it is a very basic instruments that could do most of the tasks on a test bench. The cabinet used, was available as a part of a Hi-Fi DIY System, The Range and Mode switches were Modular Stackable Interlocked MultiPole Switches. The rest of the Interface were wirewound pots, jacks, sockets and plugs. The front panel was Engraved Acrylic, the panel was the toughest issue we tackled. I wanted it to look well engineered, at least on the outside. It was a total analog instrument except for the digital indication of ICL7107. Thanks [Read More ....]

Electronic Shift Monitor

The Security Guard duty monitor below, shown in eight circuits at Digital Circuits – 1 are examples of logic circuits, i have converted them from the DOS Orcad to Orcad 9 and corrected some errors a few years back. These circuits can be used for looking at the logic blocks or to learn. This product was built and sold to some firms many years back. Now these designs are best done with a PIC or Atmel chip. Here is the user manual Electronic Shift Monitor ESM9000

ICL8038 Device Information The ICL8038 waveform generator is a monolithic integrated circuit capable of producing high accuracy sine, square, triangular, sawtooth and pulse waveforms with a minimum of external components. The frequency (or repetition rate) can be selected externally from 0.001Hz to more than 300kHz using either resistors or capacitors, and frequency modulation and sweeping can be accomplished with an external voltage…. Low Frequency Drift with Temperature 250ppm/oC Low Distortion 1%(SineWave Output) High Linearity 0.1%(Triangle Wave Output) Wide Frequency Range 0.001Hz to 300kHz Variable Duty Cycle 2%to 98% High Level Outputs TTL to 28V Simultaneous Sine, Square, and Triangle Wave [Read More ....]

Digital Clock Web Gadget for Date and Time This Web Gadget is for the Google Homepage, Web-page or blog. It has seven segment display, similar to traditional Digital Clocks in the dashboard. It will also indicate the date and week. Add to Webpage seven-segment-digital-clock The Project Page The javascript is as close as possible to a c program that you could write for a PIC processor, So then try and make a gadget which is 3D, using PIC or 8051.
