Reverse Engineering A Counterfeit 7805 Voltage Regulator
Posted on: 10 Oct 2017
Under a microscope, a silicon chip is a mysterious world with puzzling shapes and meandering lines zigzagging around, as in the magnified image of a 7805 voltage regulator below. But if you study the chip closely, you can identify the transistors, resistors, diodes, and capacitors that make it work and even understand how these components […]
Site enables detailed component comparisons
Posted on: 10 Oct 2017
Choosing components is a series of time-consuming tasks, from surveying the market for possible candidates to properly evaluating performance. As a hardware engineer who has worked in Silicon Valley for 10 years, I have spent significant time developing test plans and specs, building fixtures, and testing components. One of the reasons comparing components takes a […]
IR Tracking Turret with PIC and C
Posted on: 10 Oct 2017
This is a good learning project that is fun to build – I got a lot out of making it. I think this has been done quite a bit already, but I did not find a straightforward way of doing this with PICs. When I finally got it working, I thought I’d share it. It […]

Red Light for Astronomy Observing using PIC12F683
Posted on: 10 Oct 2017
When doing astronomy observing at night preserving night vision is critical. This requires using the minimum amount of light that makes the sky charts readable. What is this minimum level depends on how dark are your surroundings, how much time you have spent in darkness, how well your eyes adapt for night vision, what type […]
How to make a computer controlled Robot Project Using PIC16F877A? using pic microcontoller
Posted on: 10 Oct 2017
After a short break, we’re back to the DIY robot projects series and I am sure you’ll love this one too. Before that I suggest you to go through all our earlier simple robotics projects for engineering students as well. This time, major difference is the added security to access the robot; you can control […]
Do you know, what´s a top-class programmable power supply capable of?
Posted on: 09 Oct 2017
If you need to simulate overvoltage, slow start, fluctuations and other situations, which may occur in real life, then the TDK Lambda power supplies won´t disappoint you. Imagine a laboratory (testing) power supply able to provide a virtually any function. Switching on, drop-out, repeated switch-on and many other functions, by which we can test our […]
Tape Head Pre-Amplifier
Posted on: 09 Oct 2017
Description The circuit is built around a popular Sanyos stereo head preamp IC LA3161. Low electrical signals from the playback heads are fed to pins 1 and 8 of IC1 via DC decoupling capacitors, respectively. Components between pins 2 and 3 and pins 6 and 7 provide adequate equalization to the signals for a normal […]
LDO regulator is qualified for automotive designs
Posted on: 09 Oct 2017
The MAQ5300 is an automotive-qualified, ultra-small, ultra low dropout CMOS regulator (ULDO) that is ideal for today’s most demanding automotive applications including infotainment, camera module, image sensors, and anywhere PCB space is limited. It offers extremely low dropout voltage, very low output noise and can operate from a 2.3V to 5.5V input while delivering […]
