Another round of cool reads for you to enjoy!

And as always, we want to thank the hand that feeds us. So here's to the great folks at M.E. Labs for steppin up again. Check 'em out below.

That's it, Enjoy!

 
Spreadsheets - The Forgotten Analog Design Tool

 
Like Edgar Allan Poe's The Purloined Letter, the spreadsheet has been in full view for over 20 years now and yet has remained virtually invisible to the average electronics enthusiast. Far from being only a financial tool, it can easily be coerced into performing a number of useful, repetitive, and complex operations that really take the tedium out of customizing circuits.

Smiley_s Workshop
Smiley's Workshop 29
C Programming * Hardware * Projects


Previously, we got a little shifty with the 74HC595 and 74HC597 shift registers, wrote some software SPI (Serial Peripheral Interface) code, and built a new and improved (twice the eyes!) Cylon Eyes project. All to prepare for learning about hardware SPI so that we can use it to communicate with external Flash EEPROM memory.

Learning Systems for PICs

This is an educational learning system - not just another experimenter board -  for all levels of programming from beginner to expert.
 
Learn the fundamental concepts of programming, from plain-English descriptions of software tools to concepts including program flow, loops, coding techniques, binary manipulation, device-to-device communication, user-interface design, and more.
 
14 Lessons use a building-block approach to teach you incrementally, from a six-line program to a working user-interface.
 
Tutorial assumes no prior knowledge of programming.
 
All necessary hardware and software included, all you need is a computer with a standard USB port.

Light-Sensitive Circuits
Light-Sensitive Circuits
 
Electronic optosensors are devices that alter their electrical characteristics in the presence of visible or invisible light. The best known devices of these types are the LDR (light dependent resistor), the photodiode, the phototransistor, and the PIR (passive infrared) detector.
Low Voltage Insulation Tester
Build a Low Voltage Insulation Tester

Ground faults are a curse to fire alarm systems. Even a small amount of current leaking to ground somewhere in the building can cause an unscheduled fire drill. Worse yet, a second ground fault somewhere else in the building can short out the whole system. An easy modification allows a low tech analog ohmmeter to detect insulation faults that a high tech digital ohmmeter fails to find.
