THE FUN OF AUTO-ROUTING I am starting to appreciate the auto-routing features in the EaglePCB. It gets the job done and looking at the image below, saved me hundreds of hours. I am very thankful of that fact. Auto-routing is so simple. I just prepare the PCB design, make sure my schematics are correct, and […]

20220707 BiColour LEDs
I love LEDs a lot, and even more if it was in a Tricorder. And this was what got me through as an Engineer (barely). In those days, the only LEDs I could ever get was the normal dim 5mm reds, greens and yellows. Then came the ones in 3mm and later on, instead of […]
20220703 The Modified TR-595E Decals
Today is Sunday, and after personal some reflection plus its hot as heck here, I took another look at the decals. There was something nagging at the back of my mind; The TR-595E’s original front sensor array decals did not have the two white oval-like details for the pair of alternating green LEDs in the […]
DIY or BUY a SMD reflow Hot Plate?
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 […]

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 […]
