“There is nothing more satisfying then building a circuit and having it work as you intended and nothing so infuriating at it failing and not knowing why! There’s usually a few main culprits that can cause a circuit to …
“My first dub siren build was a little over complicated. Although it worked well, you needed 3 x 9V batteries to power it which was overkill and I had to build the main circuit on a prototype board. The first …
“OPAMPS and 555 timers are one of the widely used electronic ICs that we use regularly, So we need to make sure that whether ICs are working correctly or is faulty. Thus we need to make a tester that will …
“Can you be electrocuted in the bathtub? Sure — but only because the water’s not pure. Many people don’t realize that absolutely pure water doesn’t conduct electricity. This is because the hydrogen and oxygen atoms don’t have …
“Dub Siren! Man – I didn’t even know that these existed until a DJ friend asked me to make him one. I had to do some digging (a lot of digging actually – there isn’t much on the net surprisingly …
“If you are getting started with robotics, one of the first project that beginner make includes a line follower. It is a special toy car with property to run along a line which normally is black in color and in …
“Building a “semi-directional” radiation and cosmic-ray detector is not an easy feat. I aimed to design, construct, and test a portable and versatile Silicon photo-diode Radiation Detector suitable for the 5keV-10MeV detection range to accurately quantify low energy gamma-rays emanating …
“An electrocardiogram,or ECG, is a very old method of measuring and analyzing heart health. The signal that is read from an ECG can indicate a healthy heart or a range of problems. A reliable and accurate design is important …
“We built a system that modifies an existing idea that is used extensively in public restrooms: faucet automation. We created an updated design that will lead to more efficient water use in faucets. We chose this idea because the existing …
“I made surprisingly good ECG from a single op-amp and 5 resistors! An ECG (electrocardiograph, sometimes called EKG) is a graph of the electrical potential your heart produces as it beats. Seven years ago I posted DIY ECG Machine on …
“This is an LM741 op-amp built on a breadboard. The LM741 op-amp is an 8 pin IC chip, but I thought it would be fun to build my own on a breadboard. There are four sections to the chip, it …
“You might have seen my discrete 555 and 741 IC electronics kits. Well, a while back I had this idea about creating a discrete version of a microprocessor, but it just sounded too difficult, time consuming, or impractical. And part …
