SMD VS THROUGH-HOLE The advantages of using SMD components (surface mount) as opposed to the conventional though-hole versions is that SMDs are smaller. Because of that SMDs does not consume too much power. The disadvantage of using SMD components (that exists in millimeters)is that soldering them is really a b*tch. My original decades old circuits […]

A Relay Delay
Well, I have a problem now. After going through the Datasheet again, I need to either give it the correct voltage or at least close to 80%. In other words, these 5 volt relays require a minimum of 4volts before it can do anything. It was so sad last night when I rushed back home […]
20220629 The TR-595E Lower Interface modifications
It’s getting there but I am not sure if my method worked until this design becomes a reality. I mean, there are so many ‘good lucks’ when I was doing it and, well, this is too good to be true. But today, which was the very next day, my Luck changed. For the very first […]
20220630 The NE555 Multi-Channel Waveform Generator Module Sine Triangle Square Wave DIY Kits
I got this Electronic Kit some time ago, way before the Pandemic started. At the core of the circuit is a 555 IC with the circuit configuration of a waveform generator. Everyone uses this versatile chip in a lot of applications and not just for electronic kits. Kits such as sirens, Electronic pianos, LED blinkers, […]
20220623 THE FRONT ARRAY PCB
In just two weeks, the first of the three PCBs designed by Arky has arrived. I can never get bored when it comes to opening the vacuum sealed plastic. It is like opening and touching new PCBs for the very first time. I know it’s no big deal but man, my fingers were trembling. So, […]
