For a while we have been sharing many electronic projects for engineering students and then we found out there was a huge demand for embedded projects, especially PIC microcontroller based projects. After a short break, here is another outstanding one that is not only suitable for electronics engineering but mechanical engineering students too. Now coming […]

Why op amps are important Op amps are a key component in analog circuits. An op amp takes two input voltages, subtracts them, multiplies the difference by a huge value (100,000 or more), and outputs the result as a voltage. If you’ve studied analog circuits, op amps will be familiar to you, but otherwise this […]

BELMONT, Calif.–(BUSINESS WIRE)–A comprehensive study of electronics hobbyists released today found that over 68% of hobbyists believe electronics as a hobby is essential to fueling the American economy. Over 1700 electronics hobbyists participated in the study, the Great American Electronics Hobbyist Census, conducted by electronic component distributor, Jameco Electronics. In 2014, electronic component shipments in […]

A stable single transistor sine wave generator, that works with many values of input voltage.  In PartSim you can easily change the value of the resistors and capacitors and observe the effect on the frequency of the oscillator.  If you are manually calculating the frequencies, make things simpler by keeping  the values of the resistors […]

This project has only a few modifications from the “Single Chip, Four Channel Datalogger” article by Dan Gravatt in the 2008 January Issue of Nuts&Volts (page 42), so I won’t go into much detail. Below is the schematic.  The changes from Dan’s datalogger are that I used the PIC16F886, which is pin-compatible with the PIC […]

A few years ago I needed a function gen – erator for my home laboratory. In my job I had worked with some expensive commercial models and initially I had planned to buy one of these. However, none of them really was what I wanted – too complex for simple use – and so I […]

At the start of this series of posts, I said I did not want a PC to control my Milling Operations, so some local delivery method of supplying the gcode files is required. Having said that, the system is ‘open’, and a simple XON/XOFF terminal program running on a PC can be used if required. […]

Aurora 9 bar – The Essence of Aurora Since the introduction of Aurora 9×18, I received many requests for the kits and PCBs. I’m still quite undecided about making those available for a few reasons. However I really want other LED lovers (ok that might sound too much to be able to build one themselves. […]

The Compact Flash Library provides routines for accessing data on Compact Flash card (abbr. CF further in text). CF cards are widely used memory elements, commonly used with digital cameras. Great capacity and excellent access time of only a few microseconds make them very attractive for microcontroller applications. In CF card, data is divided into […]

What enclosure to use for your electronic device and how to sort them when there are several ones on one place? That´s the question reaching almost to beginnings of electronics. No wonder, that since those times a lot of solutions were developed, which were so good, that they´re actual even nowadays. One of such examples […]
