Ghost touches on a touchscreen occur on smart phones and tablets when the screen registers touches or taps without any actual input from the user. This issue can be frustrating, but there are several potential reasons and solutions for it: Screen Calibration: Check if your device has a screen calibration option in the settings. Calibrate →
Electrolytic capacitors blow up when they are pushed too hard. That’s normally a very bad thing. This hardware hack uses exploding capacitors as a propellant. For purely for innovation and engineering, this YouTube experimenter built a working capacitor revolver and tested its capabilities. I Built An Electric Capacitor Revolver! https://youtu.be/4Fy9bZEufx0?si=1iZFB-Kvs1GvOzR8 Funny idea, but not the →

I saw this circuit design at “I take pictures of electronics part @Facebook” https://m.facebook.com/groups/ElectronicParts/permalink/2237548103101179/ As many circuit designs posted to Facebook, this has it’s problems and non-idealities. Here are some comments on this circuit design: 1. At worst case LED will shine bright as a star in the sky until either it or the transistor →
IT’S A HUMBLE ‘SCOPE, BUT IT CHANGED OUR WORLD https://hackaday.com/2023/07/06/its-a-humble-scope-but-it-changed-our-world/ Now anyone seeking a connection with both Pong and the Apple II can have one of their very own if they have enough money because [Al Alcorn]’s Tektronix 465 oscilloscope is for sale. He’s the designer of the original Pong and used the instrument in →
A high voltage probe allows an ordinary voltmeter to measure voltages that would otherwise be too high to measure or even destructive. Typically normal multimeters are typically designed to measure voltage up to hundreds of volts or one kilovolt. If you need to measure higher voltage, you need to use a high voltage probe. A →
I got a mains power (230V AC) surge protector for teardown and analysis. This one is designed to be installed to DIN rail on the small electrical distribution panel or inside electrical equipment. This one was in original package but already the indicator showed that it was broken. This protector protects against voltages above 320V →
What is low Z on multimeter? Dual impedance digital multimeters have feature to control the input impedance of the multimeter. LoZ stands for Low Impedance (Z). This feature presents a low impedance input to the circuit under test. A typical digital multimeter has typically around 10 megaohms input impedance, which loads the circuit being measured →
Passive Etherner hub is special device I have seen in use in 1990′s. Nowadays there is no real use for Passive Ethernet hub, because it will not work with modern Ethernet standards (it only worked with 10BASE-T). Actually using Ethernet hub is nowadays past days as they have been for a long time replaced with →
Bang on design and use! ‘Forbidden reach around’ Tell people – just because it fits you should not plug it in. Did you know that figure 8 power cable plug (IEC 60320 type C plug also known as IEC C7) fits into XLR make connector? If it’s round outside, don’t plug an AC cord in, →
