What's the difference between 74HC595 and 74HC164? Hey guys, if you are an electronic DIY lover, you will always find a lot of similar or interchangeable components, which have subtle differences in the specs or features, therefore lead to the wrong application, 74HC595 and its similar components is an example I'm going to mention today. 2. Misunderstanding of Voltage Sharing Problem of Series Diode Since the reverse withstand voltage of the  step-recovery diode is limited, when used in a high- voltage environment, it is often necessary to use plurality of step-recovery rectifier diodes in series to meet the need of reverse withstand voltage. Due to the inconsistency in the volt-ampere characteristics, turn-on time, and recovery charges of the diode during the production process, the voltage sharing problem occurs when used in series, which causes the reverse voltage of a certain diode to be too high and damaged, disturbing the normal operation of other diodes, which ultimately affects the reliability and stability of the entire device. 3. Turn your old useless laptop screen into an external monitor For far too long I possessed an old Dell Studio laptop. It served me well for a good 5 years with a number of service centre visits, battery and hard disk replacements, formats and OS upgrades. From the past few years I have ditched the old laptop for a Macbook. Yet still, I never bothered to dispose of it. After all it still works (slow af but works!). <em>What if there is an ‘emergency’ situation where I need to use this ancient piece of technology?</em> I tried selling it, but the act itself and the price I get for it is honestly not worth it. Giving it to someone for free feels like a punishment to the person (most smartphones have better specs). Disposing it off just doesn’t feel right (yeah right! That’s the middle class in me speaking. Also not very good for the environment). 4. DIY: How to Program a Police Scanner Programming a police scanner is easy-peasy if you’re someone who’s
